Why should I buy from Feature Radiators?

Choice can be a gift and a curse, the more we have to choose from the better? Or too much to choose from and how do you differentiate?

The designer radiator market is now full of choice, many different products and many different retailers to choose from. Feature Radiators is a pioneer in this market with 19 years’ experience within the industry. We were ‘The’ original radiator retailer, only focusing on radiators, not bathrooms, not kitchens, we specialise in radiators!

Now in a diluted market we try to stand out by continuing our longstanding ethos of quality products and quality service. All of us here are self-professed radiator geeks with an eye for interior design.

For you the customer how do you possibly select the best company to go with? It would be easy enough for us to write, ‘just use us, simple’, but we think it’s best to justify that somewhat.

If Feature Radiators being the pioneer in the industry isn’t enough then consider the fact that we do evaluate literally every radiator that we sell. A strict process is undertaken when we look at a new radiator, we quite literally feel and touch the product. We obtain a sample in exactly the same way you would receive it, so we can make sure everything from packaging to labelling and how the brackets are sent are as we would expect.

Our range is second to none, just because a radiator exists doesn’t give it the privilege to adorn our website and brochures, we scrutinise quality, style, heat output, size variants, price, to name a few. What you see on our website are the best radiators, selected by people with an extensive overview of the market and in combined years, over 95 years’ experience. The people here have lived through the start of this designer radiator movement when there was literally a handful of models available to the now saturated market with copycat models and inferior models available from one pop up radiator site to the next.

We actually exist! Seems odd we need to let you know that we live and breath and we have an office, 10 humans and the UKs largest radiator showroom, in the online age this is oh so relevant, we champion those points!

Due to the fact we are humans we want to know you, not necessarily down to the knee complaint from tennis but certainly your next room décor ideas or any mood board ideas, we work with you sending emails back and forth, giving you a quick call to check the finer details, we like to communicate, we don’t disappear into the online abyss at the drop of a hat.

We’re not competitor bashers, as we are confident in what we do. That said, something we do want you to know is that a good amount of the first pagers on Google are what we deem as ‘pop up’ retailers, short life span, set up by larger e commerce companies who in the background sell anything from light bulbs to online payment systems, they are far from specialist, stacked high sold cheap. They imitate and we innovate.

Choosing radiators

Although Feature Radiators’ team is often complimented on our comprehensive range of products, we are sometimes asked by our customers why we don’t offer certain other radiators that are available from other retailers.  

Feature Radiators’ aim is to ease the decision-making process for our customers; one of the ways we do this is by using our expert knowledge to eliminate products that don’t add anything new to our range. 

There are 3 key reasons why we may choose not to sell a particular product:

1. We want to ensure that all our products meet our strict quality standards, regarding both the product and the service attached, as some radiators do not;
2. We want to avoid overwhelming our customers - There is now a huge range of “feature radiators” available, so if we didn’t limit our range, we would be offering literally 1000s of different models including numerous duplicate offerings; and
3. We want to ensure that our products offer good value for money.

To ensure quality, our business is ISO 9001 accredited; this is an internationally recognised quality accreditation and means that we have strict processes regarding what we sell and how we sell it.  To ensure that we offer the best quality, we have a step-by-step process in place for introducing new products. 

Identify a new product

1. We identify a potential new product.
   1. Either radiator manufacturers approach us with new products; or
   2. Our team seeks out a product to fill a specific gap in the market.
2. Is the supplier on our “Approved Suppliers” list? 
   1. Yes – great.  They have been scrutinised and passed our “Approved Supplier Process”; this checks things like quality and service standards, company ethos and financial health. 
   2. No – then they would need to pass the “Approved Supplier Process”.
3. We request product information and images from the manufacturer.

Scrutinise the product’s specification

1. We do this by completing a New Product form which ensures that we have considered all relevant factors when introducing a new product.  These include:

• Heat output – Does the radiator produce a good output, particularly in relation to its dimensions?
• Quality of the product – Do we feel that the quality stands up against the price?  Have the smaller details e.g. brackets been considered?
• Does this radiator add something new or different to the market? – We don’t want to duplicate products that we already sell.  
• Range of sizes
• Range of finishes
• Availability and lead times
• Delivery service   

1. Once the New Product Form has been completed it is passed to the sales, technical and marketing team and the Directors who then submit their feedback. 
2. A decision is made at this point as to whether to proceed with further inspections or not. 

Inspect a sample of the product

1. A sample is ordered. 
2. We assess the radiator and its delivery service from a customer’s perspective.
3. Negative comments are fed back to the supplier so minor issues can be resolved.  For instance, we may flag up that the packaging is not adequate.
4. Our conclusions are passed to the directors to make the final decision.

Introduce the new product to our range

1. A name is chosen based on the product’s appearance and characteristics; it may highlight a key selling point. 
2. A pricelist is completed and added to our website; this will include images and all relevant information for a customer, not just prices and heat outputs, but also useful details such as “Wall to front face measurement”.  
3. A display model is hung in our showroom for members of the public to view.

Differences between flat panel radiators

Dansk flat panel radiator

 

There are a wealth of minimalistic flat panel radiators on the market, available at a wide range of prices, but how can you tell which offer good value for money?  This article provides a clear guide on what to look for when buying a flat panel central heating radiator. 

Flat panel radiators in white are a popular option as they provide a simple inoffensive design that sits close to the wall.  This type of radiator provides a discreet “designer” option as an alternative to a bolder “feature radiator”.

A customer asked me the other day, “What’s the difference between these flat panel radiators as one is much more expensive than the other?”  So I answered the question, justifying the price difference and realised that this is a common enquiry and something worth addressing properly.

“Designer radiators” are becoming increasingly the norm in homes with a high quality finish and consumers often demand more than the “bog-standard” pressed steel, corrugated panel radiators that we are used to seeing in so many British homes.  As a consequence, the market for more stylish heating products has grown rapidly to include a wealth of flat fronted radiators but with significant variations in quality and price.  Architects, especially, are looking for radiators that optimise the space they are developing, so want high quality, slimline minimalist radiators, which take up as little living space as possible but provide a great heat output.

However, although price is often an issue, opting for the “cheapest” option in heating is rarely a worthwhile investment in the long term and customers find that they get what they pay for.

So how do flat panel radiators vary?  What differences should you be looking out for? 

Below we have detailed the various points to consider when purchasing flat-fronted or flat panel radiators. 

General

·         Guarantee period: A relatively short guarantee period may indicate lesser quality welding or thin steel.  You should be looking for a radiator with a minimum guarantee period of 5 years.

·         Independent testing: Are the radiators tested to EN442, the official European Standard?  This certificate guarantees that a radiator meets the minimum standards on various aspects including heat output, product labelling and safety. 

·         Heat output confirmation: Has an independent laboratory tested the heat output of the radiator? A BSRIA (Building Services Research and Information Association) certificate or similar will confirm that the heat output stated has been confirmed by an independent expert. 

·         Awards and accreditations: Independent recognition helps to ensure that the radiator is of a good quality design.  Look for signs that recognise the quality of the radiators and materials used such as the “RAL Steel Radiator Quality Mark”.

·         Country of manufacture: The country of manufacture does not always dictate the quality of the product but you may want to consider it alongside other factors.  Flat panel radiators are usually made in Europe, mostly in Denmark, Germany and Turkey but there are increasingly more models being manufactured in Asia.  Some bespoke models are made in Great Britain. 

Design

·         There are 2 types of flat panel radiators:

1.       Specifically designed flat-fronted radiators: These have been designed for the architects market, offering clean lines and a high quality finish.  They consist of a neat, simple design that sits close to the wall and often have a plain flat top rather than a grille top. 

2.       Standard-style corrugated steel radiators with flat panels fitted to the front: These have been designed to try and replicate the same look as those specially designed flat panel radiators, but these are usually the less expensive option as behind the flat panel is usually a mass produced, commodity product.  The nature of this construction makes them often deeper in design, causing them to protrude more into a room, and the top of these radiators may be covered with a grille. 

·        Sizes available: Increasing popularity of this type of radiator has led to an increased range of sizes available.  For instance, flat panel radiators are now available in both horizontal and vertical designs, with widths from 200mm to 3000mm and heights from 300mm to 2000mm.

·        Heat output performance: A critical aspect when choosing any radiator, no matter what type, is the heat output.  A well designed flat panel radiator will have fins or “convectors” hidden behind the front panel to maximise the heat output.  Without these fins, heat output will be significantly less, so don’t be fooled by a cheap, ultra skinny flat panel radiator; it could give you the same amount of heat out as a couple of light bulbs!

·         Finishing of the top and sides: Flat panel radiators can have open or closed sides; this does not affect the performance of the radiator and is purely cosmetic.  They can also have an open or grille top; the effect on the heat output of the radiator is negligible when adding or removing a grille.  A grille is usually added for practical reasons (mostly to stop small children putting toy cars down the back!).

·        Valve connection positions: These types of radiators come with either “side connections”, like standard pressed steel radiators, where the valves are installed at the bottom of the radiator on either side, or “underside connections”, where the valves are situated underneath the radiator, either centrally or at either end.  Underside connections are a popular choice especially on vertical radiators as they mean that the valves sit directly underneath the radiator meaning you don’t need to allow any more space to fit the valves in.  There may also be other valve connection options available should you require them.  Whichever valve positions you require, it is essential that you check with your radiator specialist that the radiator you are considering will be suitable.  

·        Design of brackets: To maximise space, look at radiators with cleverly designed brackets that keep the radiator as close to the wall as possible.    Look for the “wall to front face measurement” to confirm how far into the room a radiator will protrude, not just the depth measurement, as this may not include space for the bracket.  

Materials

·         Grades of steel – Pressed steel radiators in white are a popular product but the quality of steel can vary between models.  A thick grade of steel, such as 1.20mm or 1.25mm internal construction will help ensure a long life.   Front panels should be a minimum 1.1mm thick steel; top quality flat panel radiators may even be 2mm thick steel. 

·         Pressure-testing – Flat panel radiators should be tested to a minimum of 10 bar. 

·         Paint quality: Flat-fronted radiators in white or coloured paint finishes are “powder coated” and should have a smooth, semi-gloss surface, similar to those seen on home appliances.  Poorly finished radiators may have a “orange peel” effect due to little paint being used. 

·         Quality of brackets: Brackets can give an immediate indication of the quality of the manufacturing, as a poor quality bracket may well reflect a poor quality radiator.

·         Packaging: Make sure the product you are purchasing is adequately packaged as transit damage could cause delays to your project.  Ask your retailer how the radiator is packaged. 

Service

Always bear in mind the service provided when you purchase heating products.  Follow the guide below to ensure you get the best service possible and minimise the chance of encountering problems. 

·         Choose a reputable supplier.  Look for reviews or feedback online, or ask friends and family whom they used when buying a radiator.   

·         Look for awards and accreditations.  Independent recognition of the supplier will help back-up their reputation, and will indicate that they have a brand they care about and wish to protect.

·         Use a radiator specialist.  Even kitchen, bathroom or bedroom retailers may have limited knowledge on heating.  By using a true specialist, you can get any technical and installation questions answered quickly and accurately.

·         Ask how long they have been selling radiators for.  Although the “designer” radiator industry is relatively young, a reputable supplier should have a number of years of successful trading behind them. 

·         Avoid online only sellers and “Add to basket” shopping.  If a radiator is chosen without expert advice, it can often lead to the wrong products being ordered, causing problems for all parties involved. 

·         Find out if they have a showroom.  High quality premises can indicate a long-term outlook for the business. 

·         Ask about after-sales service.  For instance, does the supplier have technical specialists and a helpline?  Some retailers have been known to fob off customers with the phone number of the warehouse, when they report a faulty product.

It’s clear from the above that choosing a flat panel radiator may not be the most straightforward decision, but by following the guidance detailed above, your radiator won’t be a false economy.

How to Bleed a Radiator

To ensure effective performance of a water-filled radiator, you need to make sure that the radiator has been "bled" properly.  Bleeding a radiator means getting rid of any air that has accumulated at the top of radiator. When air is present, there is no water, which means no heat. Bleeding a radiator is done by opening an “air vent” otherwise known as a “bleed valve”.  Ideally radiators should be checked for air accumulation at least once a year.

To bleed a radiator you will usually require an appropriate tool, namely a flat headed screwdriver, a “bleed key” or a spanner.  Bleed keys (vent keys) are not included as standard but can be purchased from a plumbers' merchant or home improvement store. 

Bleeding a radiator is a simple process:

1.    Ensure both valves at the bottom of the radiator are open;

2.    Get a bleed key (vent key), screwdriver or spanner ready to open the bleed valve (air vent) at the top of the radiator.  Have a rag or cloth ready to catch minor drips;

3.    Use the tool to open the air vent and release the air holding the cloth underneath;

4.    Listen for the change in sound; you will hear a hissing noise at first, which is the sound of air escaping.  Vent the radiator until the sound changes and you get a steady stream of water.  At this point you can retighten the air vent using the tool.

5.    Once you have bled the radiator, turn the heating back on and leave the system to flow for half an hour.

Please note: On first filling a system, it is air that is vented from a radiator. However, from then on the periodic venting required is actually releasing hydrogen that is the by-product of rusting in the system.  If regular bleeding is continually required, then this is a strong indication that the system requires draining, cleaning and refilling incorporating a corrosion inhibitor to prevent further rust in accordance with BS5449 section five commissioning.  Alternatively, if regular bleeding is required then this could indicate a leak that is letting air enter the system.

Alternatively modern radiators do sometimes come with “automatic bleed vents” which release air from a radiator whenever necessary, meaning that you do not need to bleed the radiator manually.  These are great for convenience, however there are instances of automatic bleed vents causing damage to a radiator as regular venting can mean regular water seepage which can lead to corrosion.

Hotting up for Summer

With summer just around the corner, the time to store away the winter bedding and take the heating off its timer is fast approaching.  But before you bask in the sunshine and the harsh winter nights become a distant memory, spare a thought for your radiators.  Not surprisingly, most of us don’t think about heating our houses until its cold.  But when it comes to changing your radiators, summer is the best time to do it.  No need to shiver without heating in the cold months, wait for your plumber to slot you in, or limit your choice of radiators to stock items because you need warmth quickly. 

 
If it’s stylish radiators you want, then there’s good news as there is now a wealth of stunning designs on the market.  From traditional cast iron to cutting edge contemporary designs, there’s something for everyone.  While some radiators are designed to make a striking statement in a myriad of colours and finishes, others can blend discreetly into walls so you barely notice they are there.  There are central heating, electric and dual fuel formats and with a wide range of pricing, there are models to match every budget.  “Feature radiators” are now a firm favourite amongst architects, developers, heating engineers and homeowners alike, not just for their aesthetic appeal but also for the high heat outputs they can provide.  

As heating requirements change to reflect the way we live, the market has been quick to respond with innovative products to match demand. For example, electric radiators, such as the award winning iRad from Feature Radiators, have become the product of choice putting the heat and all year usability into garden buildings and summerhouses.  And in line with the increasing number of sliding folding doors and large picture windows gracing our homes, “trench heating” has been launched, an ingenious and efficient heating solution that has the additional benefit of eliminating condensation and the cold feel of glass.   

Choosing the right radiators for your home is crucial and contacting a true radiator expert will ensure that you get it right.  Look for a company whose sales team don’t work on commission to ensure that the advice you receive is genuine and unbiased; a knowledgeable and solution driven sales person will guide you to the best product in terms of heat output, budget, style, dimensions, finish and lead times; quality is vital as well as functionality, design, and of course value for money. 

It is crucial to consider that your particular situation will have its own unique set of requirements and restrictions, whether the issue is lead time, budget, heat output, limited wall space, design or all of them.  So if you want to review your heating system to find the best way of meeting your specific heating needs, then speak to a radiator specialist.

Radiators for kitchens

The kitchen is increasingly becoming the heart of the home, so it’s no surprise that radiator experts are often asked: “Which radiator is best for a kitchen?” The answer will depend on the specifics of your kitchen, but there are some common factors that apply to all kitchens when considering heating.

Heat output
This is always the first and most important factor. Speak to a radiator specialist or heating engineer to find out how much heat your kitchen needs from radiators to ensure a comfortable environment.

Space
As kitchen cabinets often take up the majority of wall space, finding a suitable place on the wall for a radiator can be a challenge. However, with so many different shapes and sizes of radiators available, there is likely to be a simple solution, such as a vertical radiator that can be positioned behind a door or on a pillar taking up otherwise unused space.

Hanging tea towels
You may wish to dry tea towels on a kitchen radiator so options could include a heated towel rail in ladder style with towel hanging space or, for more heat output, go for a radiator with a towel-hanging rail attached.

Valves
Due to the fluctuating temperature of a kitchen, from the hob, oven and other appliances, experts recommend the installation of thermostatic valves. Thermostatic radiator valves (TRVs) have an in-built temperature sensor. The thermostatic valve maintains room temperature, by automatically adjusting the heat output from the radiator.
This means that you can make the most of any “free” heat the room receives, such as that from the sun, gas cookers or electrical appliances. As the valve is controlled automatically, it turns itself up and down, ensuring the radiators perform as efficiently as possible, reducing energy waste. For this reason, TRVs are the environmentally friendly valve choice.

Hygiene
It’s always worth considering hygiene when choosing appliances and materials for use in the kitchen. Radiators with a smooth finish are generally easier to wipe clean than radiators with a textured finish. Where possible, it is a good idea for the radiator’s pipework to come out of the wall instead of up from the floor. This will make mopping the floor easier and will limit areas where dirt could build up.

Matching
In order to really finish off a room and ensure a high quality finish, clever matching of finishes is essential. This can be done in all manner of ways as considered below.
Is there an Aga or Rayburn in your kitchen? If so, look for a matching paint finish on your radiator.
Going for granite worktops? Then consider a granite radiator; choose from a variety of stones such as Nero Assoluto. You can now even get radiators made of Silestone, a natural quartz material that is popular for use on kitchen work surfaces.
If you have a cooker hood in a brushed finish, then why not consider a radiator in brushed stainless steel to match.
And for those finishing touches, don’t forget your valves; a high quality valve in a matching finish can link key features together. Why not match your radiator valves to your light switches, cabinet handles and/or plug sockets for a high-end look.

Don't rush into a decision when considering the radiator(s) in your kitchen design. Think carefully about the position, design, practicality and finish of your radiator. Speak to an expert who will be able to guide you in the right direction, helping you avoid common pitfalls and enabling you to make the best choice for the heart of your home.

Which radiators are most efficient?

The question “which central heating radiators are most efficient?” is not straight forward, as in this context the word “efficient” means different things to different customers.

An official definition of the word “efficient” is:

“Acting or producing effectively with a minimum of waste, expense, or unnecessary effort.”

http://www.thefreedictionary.com/efficient

It can be argued that all central heating radiators are equally efficient insofar as the energy put into a radiator will equal the amount of heat it gives out. In other words, all properly functioning radiators with same heat output capacity, will give out the same amount of heat as one another and will use the same amount of energy to do so.

Radiators are just vessels designed to release energy in the form of heat. The amount of heat they release will depend on the amount of energy put into them.

In asking “Which central heating radiators are the most efficient?”, customers could mean:

1. Which radiator gives out the most heat for its size?
2. Which radiator is the cheapest to run?
3. Which radiator wastes the least fuel?
4. Which radiator heats up the quickest?

Relevant factors to consider in answering the above questions and ensuring you get the right radiator(s) for your specific needs are considered below.

Size and surface area

Its surface area determines the maximum heat output capacity of a radiator. The larger the surface area, the higher the potential heat output.

Surface area will be greatly increased by convectors, fins, or double or triple panels. So for example, the heat output capacity of a flat single panel radiator will be considerably less than a radiator of the same size (height x width) with double panels, and/or convectors or fins.

When considering one model of radiator, then generally, the bigger the radiator, the bigger the heat output. However this is not necessarily the case when comparing one model of radiator against another.

Water content

In theory, the less water a radiator holds, the less time it takes to heat up, and the less fuel is would require to reach full temperature. Consequently, the lower the water content of a radiator, the more “efficient” it could be considered to be. However, in reality, there is little difference in the level of water content across radiator models, although over an entire system the slight variation would multiply.

Design
The shape of a radiator and its design does have an effect on the amount of heat it radiates, but again this is due to the particular surface area of the model. For example, a tubular radiator with hollow tubes offers a lot more surface area than a flat panel design without fins as the heat can be emitted from both the outside and the inside of the tubes. So the design of a radiator does have a direct effect on its maximum heat output.

Material
A radiator’s material of manufacture does not have a direct impact on the amount of heat it gives out. However, the material will be a determining factor in the speed in which the radiator heats up and cools down. For instance, aluminium heats up quickly and cools down quickly, whereas cast iron heats up at a slower rate and cools down at a slower rate.

Finish

Science proves that the finish of a radiator affects its heat output in varying degrees.

There is a principal known as “emissivity” that enables experts to measure the ability for heat to leave (or radiate from) the surface of an object.

Levels of emissivity vary between finishes of radiators. Painted radiators have a higher level of emissivity than bare metal radiators, meaning that painted finishes absorb and release heat more than bare metal finishes. Matt finishes have a higher level of emissivity than gloss radiators. Even the colour of the finish can affect the level of emissivity. For instance, black paint has a higher level of emissivity than white paint. However, the difference in the emissivity of radiators is negligible and would only be realised in laboratory conditions.

Only a chrome finish has a noticeable affect on the heat output of a radiator as chrome has a very low level of emissivity. The chrome coating works on the same principal as the space blankets (the silver insulation blankets) used to keep athletes warm. The chrome coating, whilst looking beautiful, does reduce the ability of the radiator to radiate heat. Chrome (chromium plated) radiators are proven to emit approximately 20% less heat than the equivalent sized radiators in a painted finish.

In theory, the optimum radiator when looking for high heat output and rapid heat up time, taking all factors into account (no matter how minimal their impact) would be a matt black aluminium radiator with the greatest surface area for its size.

In practice, there are many other aspects that will determine the best radiator(s) for your project, including, aesthetics, dimensions to fit your space, budget and availability. Your choice will be governed by which factors take priority.

Air vent - A small valve, which enables air that has accumulated at the top of a radiator to be let out or ‘bled’ from the radiator using a special air vent key. Also known as a bleed valve or bleed vent.
Angled valves - Valves that have a 90° turn on them for use on radiators with side valve connections, where pipe work is coming up from the floor or out of the wall. Also used on radiators with underside valve connections, but only where the pipe work comes out of the wall. See also "Straight valves".
Balancing - Adjusting the flow of water throughout a piped central heating system in order to achieve a similar drop in temperatures across all radiators. It is important to ensure that heat is distributed evenly to all radiators so that they all run at equal temperatures and all take an equal amount of time to reach their operating temperature. A plumber should ‘balance’ the system after installing radiators. Lack of balancing within a system is often the cause of cold spots on radiators, radiators failing to heat up properly or noisy radiators.
BBOE – Bottom Bottom Opposite Ends - Radiator valves are installed at the bottom of the radiator, on either side.
Bleeding a radiator - Getting rid of any air that has accumulated at the top of radiator, using an air vent or bleed valve. Trapped air in a radiator will result in a radiator failing to heat up properly.
Bleed valve - see "Air vent"
Bleed vent - see "Air vent"
Boiler - a device that heats water using gas, oil or electricity. This is the most common way to provide hot water central heating for domestic properties.
Bracket - a part used to secure/fix radiators to the wall
British Thermal Unit - (BTU or Btu) is a traditional unit of energy equal to about 1,055 joules. It is approximately the amount of energy needed to heat 1 pound (0.454 kg) of water (therefore around 0.1198 gallons) from 39 to 40° F (3.8 to 4.4° C). This unit of measurement is now being replaced with the alternative unit of measuring heat output, Watts.
BS 3528 - The old British standard for radiators. BS EN 442 has now superseded this.
BS 5449: 1990 - The British Standard for internal room temperatures, identifying acceptable comfort levels.
BS 7593: 2006 - The British Standard for the treatment of water in domestic hot water central heating systems, including the use of corrosion inhibitors and cleaners.
BS EN 12828 & 12831: 2003 - British Standards for designing heating systems.
BS EN 442 - The official European Standard for radiators. It covers various standards that radiators need to meet including heat output, minimum material thickness, pressure tests, paint quality, product labelling, safety, etc.
BTU – See "British Thermal Unit"
Bush – see "Reducer"
Central Heating – A system that provides warmth to the whole interior of a building (or portion of a building) from one point to multiple rooms.
Closed System - A piped central heating system that is "closed" or "sealed" means that the water contained within the system is taken from the water mains upon installation. Once filled and pressurised the system is sealed off and then the water within the system is circulated repeatedly around the system and is not (unless actioned via the filling loop) replaced by new water entering the system.
Combi boiler - a device that provides both central heating and hot water. A combi boiler is a high-efficiency water heater and a central heating boiler, combined (hence the name) within one compact unit. Therefore, no separate hot water cylinder is required, offering space saving within a property. "Combis" are a very popular choice for domestic properties.
Combination boiler - see "Combi boiler"
Convector - a device that is designed to "convect" heat, using the physics of warm air rising and cold air falling to create a natural cycle of air circulating around a room. Radiators convect heat as well as radiating heat.
Corrosion inhibitor - a chemical that installers add to the water in standard piped central heating systems to prevent internal corrosion of non-inert metals as per BS 7593: 2006. Examples of corrosion inhibitors include Fernox MB-1 and Sentinel X100.
Direct System - Cold water is taken from the mains and goes directly to points of delivery (taps) around a property where cold water is required.
Dt - Also written as Dt or Delta t. "BTUs" or "Watts" are a measure of how good a radiator is at heating a room at standard temperature; the Dt value defines what that standard temperature is. Naturally the hotter a radiator is, the more heat it gives out. Since water cools on its passage through a radiator, the temperature of the water entering it is higher than the temperature of the water leaving it. The mean value of the inlet (flow) and outlet (return) temperatures is taken and the approximate room temperature is subtracted from this figure, universally quoted as 20°C. The difference, known as Dt, is the operating temperature that is given in the radiator’s specifications.
Dt of 50°C - Delta t 50: The European standard for the operating temperature of central heating systems, which determines the heat outputs achievable from radiators.
Dt of 60°C - Delta t 60: The British standard for the operating temperature of central heating systems, which determines the heat outputs achievable from radiators.
Duel Fuel - A radiator that is connected to the central heating system, but also has an electric element for use in the warmer months when the central heating isn't turned on. A popular choice for bathroom radiators.
Economy 7 - An electricity tariff, where you pay a different price for your electricity at different times of day, so the electricity you use at night costs less than the electricity you use during the day - a bit like peak and off-peak phone calls. It's called "Economy 7" because you get cheaper electricity for 7 hours each night. Some appliances, like storage heaters, are designed to take advantage of the cheaper electricity available during the night.
End bush - see "Reducer"
Expansion tank - The tank at the top of on open system, which allows the expanding hot water from the cylinder to spill out and be stored.
Expansion vessel - A small tank used in closed water heating systems and domestic hot water systems to absorb excess water pressure, which can be caused by thermal expansion as water is heated. The vessel itself is a small container divided in two by a rubber diaphragm. One side is connected to the pipe work of the heating system and therefore contains water. The other, the dry side, contains air under pressure. This is not the same as an expansion tank.
Flow - In central heating terms, this refers to the water coming from the boiler and also the point at which water enters radiators. See also "Return".
Heat calculations - These are performed in order to work out the heat output requirement of a room. The calculations are based on numerous factors, but are primarily based on the volume and type of room. The actual size of the radiator required to achieve the required heat output can also be affected by other factors: see "t" and "Mean Water Temperature".
Heat output - the amount of heat that is emitted from a heat source. The heat output can be measured in units of Watts or British Thermal Units.
Indirect System - Cold water is taken from the mains and enters the property. It has one draw off point (generally the kitchen sink) as well as pipework that feeds the cold water tank. The stored water in the tank feeds all other cold water points in the property.
Inert metals - Do not corrode when in contact with oxygenated water. Examples include stainless steel, copper and brass. Non-inert metals include mild steel, cast iron and aluminium and are used on central heating systems in conjunction with corrosion inhibiting chemicals as per BS 7593: 2006.
Joining nipple - a metal collar with opposing threads at each end, which acts like an internal nut and is used for joining radiator sections together.
Lockshield - A valve that is used to restrict the flow of water on the return side of a radiator in order to "balance" the radiator on the system. Valves usually come as a pair and the "lockshield" valve is supplied along with either a "thermostatic" or "manual" control valve. See also "Return" and "Balancing".
Manual radiator valve - Act simply like taps as they directly control the flow of water into a radiator and consequently how hot the radiator gets, regardless of the surrounding room temperature. Manual valves have no labelled settings – you simply turn the valve head until the radiator is giving the amount of heat desired.
Mean water temperature (MWT) - The mean temperature of the water in a central heating system. For example; a system operating at 90-70-20°C will have a mean water temperature of 80°C
Microbore (piping) - pipe that is only 10mm and 8mm in diameter that is narrower than the standard 15mm copper pipe or traditional 22mm pipe.
Nipple - See "Joining nipple"
Open System - an un-pressurized central heating system. Water is drawn into the system from the mains when required via the expansion tank. As water heats up and "expands" in the system, the excess water is released as necessary back into the expansion tank, which is usually, but not always found high up within a property. Also known as an open-vented system.
Pipe centre measurement - the measurement from the centre of one pipe to the centre of another pipe and the measurement from the wall to the centre of the pipe. This measurement is useful for the installation of pipework for a radiator; especially where pipework is to be installed before the radiator is present.
Pressurized system - see "Closed System"
Radiator - a device that is designed to "radiate" heat, to force heat outwards. In reality, most radiators also convect heat to some degree, for example most standard corrugate steel panel radiators radiate 85% of their heat and convect 15% of their heat.
Radiator valve - see "Valve"
Reducer - a part that is designed to reduce the size of a connection, often used on radiators. Also known as an "end bush" or "bush".
Return - This refers to either the water going back to the boiler or the point on a radiator where the water exits. See also "Flow".
Sealed system - see "Closed System"
Secondary Hot Water System - a piped central heating system where the water that runs through the system is the same water that comes out of your taps. As a consequence, the water needs to be clean and free from chemicals, so radiators and parts on this system need to be made of inert metals such as copper, brass or stainless steel. Parts made of mild steel, aluminium and cast iron, which need to be used in conjunction with corrosion inhibitor, are not suitable.
Straight valves - Valves that are straight for use on radiators with underside connections where the pipes are coming out of the floor.
Tap - A valve controlling release of liquids or gas. The word 'tap' is sometimes used as an alternative to 'valve'.
Tapping centre measurement - The distance between the valve connection points on a radiator.
TBOE – Top Bottom Opposite Ends - Radiator valves are installed at the top on one side of the radiator, and the bottom of the other side of the radiator.
TBSE - Top Bottom Same Ends - Radiator valves are installed at the top and bottom on the same end of the radiator.
Thermostatic Radiator Valve (TRVs) - Include an in-built temperature sensor. A thermostatic valve will maintain a space at the temperature selected, by automatically adjusting the heat output from the radiator. As a thermostatic valve is controlled automatically, it turns itself up and down, ensuring the radiators perform as efficiently as possible, reducing energy waste. For this reason, TRVs are the environmentally friendly valve choice as they prevent energy wastage.
Towel radiator - A radiator that is designed specifically to warm towels as well as a room, often used in bathrooms or kitchens.
Towel rail - Historically this phrase just meant a rail for hanging towels, but over recent years this phrase has come to mean a radiator that has been designed to keep towels warm and dry. It is now used in both instances. Other terms used included heated towel rail and towel radiator.
TRV – See "Thermostatic Radiator Valve"
Un-pressurized system - see "Open System"
Valve - A device that regulates, directs or controls the flow of a fluid by opening, closing, or partially obstructing various passageways. In radiators and central heating systems, valves are used to control water flowing around a system and particularly in and out of radiators.
Wall tie - a device used to attach a radiator or similar to a wall. Sometimes called a wall stay.
Watts - A derived unit of power in the International System of Units (SI), named after the Scottish engineer James Watt (1736–1819). The unit, defined as one joule per second, measures the rate of energy conversion. In heating, watts are used to measure the heat output given by a heat source such as a radiator.
75-65-20°C operating temperature - Water on a hot water piped system will leave the boiler at 75°C and return to the boiler at 65°C losing a nominal 20°C across the whole system. See also Dt 50°C
90-70-20°C operating temperature - Water on a hot water piped system will leave the boiler at 90°C and return to the boiler at 70°C losing a nominal 20°C across the whole system. See also Dt 60°C
