Choosing the right Radiator FAQ:

Can I have a radiator in the colour of my choosing?

Most manufacturers offer a colour chart allowing for a bespoke colour to help match your decor. Please see our Bespoke category or contact us with your requirements. In some instances, we are able to provide a colour swatch from the manufacturer.

Click here to see our Bespoke range!

Can I replace my existing radiator with a radiator exactly the same size?

The chances are yes, you can. We supply a wide range of both imperial and metric sizes. A radiator of the same size, length, in particular, saves the need for amending your pipework, enabling just a straight swap. Put your desired size into our Find A Radiator calculator or contact us with your requirements. Some of our products display the radiator Pipe Centres, which will assist when replacing an existing radiator. Contact us if you require assistance.

What heat output should my radiator be?

The required heat output for a room is determined by a range of factors which include room size and the type of room. You could begin, as a guide, by using a simple heat calculator which will give you an indication of the heat required for a specific room.

However, always get a second opinion from your plumber or heating engineer as they will be able to take into account any elements that might potentially impact the heat. There are more complex calculations for properties that have specific issues due to age, location, heating system etc. so if you think your property will have issues, ask a heating consultant to do the necessary calculations.

Please be aware that the heat outputs of your chosen radiators probably won’t be exactly the same as your heat requirement, so for that reason, choose a radiator with a higher rather than lower heat output and fit thermostatic radiator valves so you can control the room temperature. Remember as well that you may have more than one radiator in a room, so combine these radiators’ outputs.

What colour and finish radiator should I choose?

Radiators have come a long way since the days of ‘you can have any colour as long as it’s white’ – today radiators, and not just designer radiators, are available in a wide range of colours and finishes. White Radiators are the standard radiator colour.

They are quickly available, they look clean and modern, generally have high heat outputs and they tend to be a little less expensive than their more colourful peers and they will fit within any home or office decor. In most instances, they blend into the background and that may be the ideal solution for most homeowners who seek a practical and cost-effective heating solution.

Radiator Colours are becoming very popular for homeowners, architects and designers. A lot of our radiators are available off the shelf in a non-white colour. Choose radiators from a wide range of factory colours available, or, if you would like a particular radiator in a specific design or colour, contact our team who will work with you to help you achieve your look.
Chrome finish Radiators have recently become a fashionable and stylish choice of finish for radiators, particularly in bathrooms, but now in lounges and kitchens. As a rule chrome radiators have a lower heat output, so remember to bear this in mind when specifying your radiators.
Stainless steel Radiators are a great material to consider when specifying your radiators. Stainless steel will not corrode, flake or peel and there will be no discolouration of the finish. Stainless steel is also a very stylish, on-trend material and will look great in a modern home and commercial settings.

What material should my radiator be made from?

Most radiators are made from steel, but there are many different benefits of using alternative materials for radiators such as aluminium, cast iron or stainless steel. Aluminium tends to heat up faster making it an excellent heat conductor, aluminium is also more eco-friendly than steel to produce.

Cast iron radiators are an excellent fit for those wanting exceptionally well build and heavier radiators, blending a classic look but built to modern standards. Cast iron radiators may take longer to heat up but once the central heating is turned off, the heat dissipates longer than traditional steel radiators. You can enjoy the warmth for hours after your central heating has been turned off! Steel radiators are excellent heat conductor and compared to cast iron, heats up reasonably quickly.

Should I choose a Designer Radiator?

Designer radiators have become very popular in recent years. Designer radiators are a design statement and can in themselves, become a focal point in any room. If you are looking for a statement piece, perhaps an unusual shape, a particular material or a radiator in a bespoke colour, and you don’t want a standard radiator, consider a Designer radiator.

What radiator should I put in my Kitchen?

The choice is yours! Vertical radiators are a great choice for kitchens, click here to see our kitchen range for suggestions!

What accessories should I buy with my Radiator?

We have a fantastic range of accessories ranging from valves to towel rails! Most of our radiators don’t come with valves and they will be a separate purchase, but our team is always on hand to lend a hand if you need any help choosing accessories.

What is the difference between thermostatic radiator valves (TRV) and manual valves?

The difference between Thermostatic Radiator Valves (TRVs) and manual radiator valves is that one has an in-built temperature sensor and the other is effectively a tap. A TRV, with its in-built sensor, will the room temperature at a constant level. The manual valves are effectively the same as taps – you turn the valve to control the temperature of the room. However, with no thermostat, you will have to keep an eye on the temperature yourself as the radiator will stay at that temperature regardless of how hot or cold the room actually is. TRVs are recommended to be installed on your radiators because they allow for full control and therefore energy efficiency. Rooms of high humidity such as a bathroom may be better controlled with manual radiator valves, as these rooms may provide false readings for the TRV.

Do I need straight or angled radiator valves?

The type of valves that you need would depend on the pipework of where the radiator is required and the style you’re looking for. With hundreds of different valves and accessories available, we understand it can be daunting. 

If the pipework comes from the floor, you need straight valves. But if the pipework comes from the wall, angled valves would be the best choice.

Check out our accessory range today!

If you’re ever in doubt, feel free to contact a member of our team and we would be happy to help!

Horizontal or Vertical radiators?

Horizontal radiators are by far the more popular choice and have been for a number of years, however, Vertical radiators take up less wall space at a lower level which enables more flexibility with interior design and decoration, such as more options with re-siting furniture. Vertical radiators also provide an exciting design solution and can in themselves become a focal point in the room.  

Why would I choose Cast Iron radiators?

Some of the benefits of cast iron radiators are that they are extremely well built to a modern standard with a classic style. As cast iron gradually cools down, once the room hits an optimal temperature you can turn off the heating and enjoy the warmth for hours to come! Click here to take a look at our cast iron range today!

Why would I choose aluminium radiators?

Aluminium is a fantastic modern material for a radiator with a heap of benefits to make you choose it over steel. Aluminium is more eco-friendly to manufacture, not only does it take less energy to manufacture, but it also uses less energy and water to heat up the radiator! Available in central heating and electric, we have a great abundance of ranges to choose from in a range of sizes and designs! Click here to take a look at our aluminium range today!

What radiator should I choose for the bathroom?

Traditionally, a towel radiator is best suited for a bathroom. With an abundance of towel radiators to choose from, it can be difficult to choose the right radiator for you. With electric towel radiators becoming more and more popular, with good reason, choosing an electric radiator can save you money on your household bills all year round. Most houses at the moment may have a radiator in the bathroom that is connected to the central heating, and when the heating is turned on, the bathroom is absorbing heating even when no one is using it. Resulting in a higher energy bill, but when you convert it into an electric towel radiator for your bathroom, have full control over the energy consumption! With full control over the bathroom’s heating supply, you have the ability to switch the radiator on when you need it and off when the bathroom isn’t in use. But the final choice is always yours and if you have any trouble choosing, our team is always here to help! Click here to check out our bathroom range today! 

What are Low Surface Temperature (LST) radiators and why would I need them?

LST (Low Surface Temperature) radiators are created with safety in mind, mainly seen in hospitals, schools and nursing homes. LST’s are manufactured so that if someone were to fall or touch the radiator, they wouldn’t be burned by the heat of the radiator but still offer an optimal heat output. 

What radiators should I use in an office?

Much like any home, an office isn’t complete without a radiator. It can be a key feature that stands out from the decor of the room or it can be a part of the furniture that blends into the room.

Whether you’re looking for a radiator for a commercial or a domestic setting, we have a wide spectrum of radiators for you to choose from!

If you’re looking for a standard radiator that serves more of a practical purpose than a fashion statement, check out our range of Myson radiators! But if you’re looking for something a little more stylish, take a look at our Purmo radiators!

What is a P1, K1, K2, P+ AND K3 Radiator?

P1 – Single panel without any fins, K2 – Single panel single convertor, P+ – Single panel double convertor, K2 – Double panel double convertor, K3 – Double panel, triple convertor.

These are just some examples of the terms used, but some manufacturers use different terms. Click here to learn more about the different terms used.

If you have any issues or questions about the terms that we use, please feel free to contact a member of our team and we are happy to help.

I need a boiler, pipework and other plumbing equipment, where would you recommend?

Check out our sister company for all your plumbing needs! BHL can source over 130,00 different products from plumbing parts to garden supplies.

Can you bend radiators to fit around a bay window for example?

We wouldn’t recommend bending a straight radiator as this would void any warranty if something was to go wrong. But we have an extensive history with the manufacturers of the radiator we sell, if you contact us and provide us with the measurements needed, we will be able to see if the radiator can be manufactured as a bespoke/one-off radiator.

Feel free to email our team at [email protected] or call us on 01226 369631.

How are the heating outputs in BTU and Watts calculated?

The heat output or BTU (British Thermal Unit) is an efficient way to calculate how much power a radiator needs for each room. Several factors will need to be considered when estimating the BTU required, such as the size of the room, what type of room the radiator is needed for and if the windows have double glazing or not.

But to help you calculate an estimated BTU, our team has created a handy calculator for you! Click here to visit our BTU calculator.

Are radiators now a design statement?

Installing a Radiator FAQ:

Do you have preferred installers you can recommend?

Our headquarters are located in Barnsley, South Yorkshire and if you’re in the local area we recommend Bumford Heating Ltd as a local heating specialist. Operating since 1968, Bumfords has extensive experience in installing, servicing and bespoke solutions across South Yorkshire and Derbyshire.

Where do radiators need to be in the room?

The location of a radiator will depend on where the pipework is built into your home, if the pipework is in a place that isn’t preferred or isn’t long enough or is too short, it can be moved/adjusted but this will have to be done by a professional plumber.


Does moving my radiator affect my interior?

Removing a radiator can be a simple procedure, we always recommend hiring a professional plumber to remove the old radiator and install the new one when it has been delivered. Removing a radiator doesn’t necessarily affect the interior of your home, but depending on if you’re changing to a different size you may need wall brackets behind the radiator to support it.

Does the condition of my wall matter?

In most cases yes, all radiators will need wall brackets to support the weight, this is vital for vertical as they will need to support a lot more weight than a horizontal radiator. If the wall that the radiator is being attached to is weaker than normal or has structural damage, we recommend speaking to a professional plumber to see if this is something that they can repair.

Can I hang my radiator on a stud wall?

In some cases, yes. Aluminium radiators are known to be lighter and can be fitted to a stud wall. But radiators that are made out of cast iron and steel are too heavy to be added to a stud wall.

Can the pipework be laid before the radiators are delivered?

We recommend that everything is prepared before the radiators are delivered and installed just in case there are any problems, but yes the pipework can be laid out before the radiators are delivered. 

Who should install radiators?

If you have the knowledge of how to install a radiator, by all means, you can install the radiator yourself. But if you don’t have the experience, we would recommend speaking to a local professional plumber to have the radiators installed. This way, if you were to run into any problems with your heating system, they can be resolved straight away.

Are electric radiators safe?

Yes! Electric radiators are incredibly safe, and with testing standards so high, electric radiators go through rigorous testing to make sure they are suitable for home use. 

Can I replace just one radiator on my system or do I need to change all of them?

If you need one or two radiators, it isn’t necessary to replace all of them in your home. You will need to drain the radiator first of any excess water before removing it to prevent any mess from being created, this may create more work for a singular radiator but this means not all radiators would need to be replaced in your home.

What radiators do I need to use with my heating system?

All central heating radiators can run off most heating systems, but electric radiators are cut off from the heating system and can be run from the electricity of your home and dual fuel radiators are the best of both worlds that can be switched from one to the other.


Can radiators be used with microbore pipework?

Microbore plumbing pipe is a type of small-diameter plastic or copper tubing used to supply hot water to radiators from the boiler. Most of our radiators can be adjusted to be installed on microbore pipework but you will need a bore reducer for this to work.

Here is a link to all of our accessories which include microbores and more!

I’d like a bespoke, made-to-order. Can you provide it?

Yes! We offer a broad range of bespoke radiators in different sizes, colours and styles. Our team at Radiators can source a number of radiators fit for any room including towel radiators, column radiators and even cast iron radiators!

Radiator Maintenance and Trouble Shooting FAQ:

Do my radiators need bleeding?

A great way to check if your radiators need bleeding is to see if there are cold patches but the top and the bottom are warm, if this is happening to you, your radiators may need bleeding. This is when you let traped air out of the radiator so that the water within can circulate properly.

My radiator is leaking! What do I do?

If you have a small leak on your radiator, it may be a manufacturing issue. But if the radiator is leaking from the pipework or is leaking a large amount of water, this may require a plumber to resolve.

If you’ve bought the radiator from us and you’re ever unsure please feel free to email the details and photo’s of the leak to [email protected] and our team will be happy to help.

How do I keep my radiators clean?

Cleaning a radiator can be a simple process, follow these steps to help you clean your radiators:

Step One: Turn off your heating/heat to your radiator.

Step Two: Vacum inside and around to remove as much dust and debree from the radiator.

Step Three: Use a damp cloth and brush over the radiator to clear up any final pieces of dust/dirt on the radiator.

Step Four: Dont forget the skirting boards! Use a damp cloth and wipe up any debris that may be caught on the skirting board.

My existing radiators have a few dents and scratches. What can I do?

If your current radiator are scratched, we may be able to source touch up paint to get the radiator looking fresh again! But if the radiator is dinted, there may not much that can be done. But you may be able to source a local radiator repair company that could repair your radiator rather than replace it.

Why don't all my radiators get hot?

If you find that not all of your radiators are not getting hot, you may need to powerflush your system. A powerflush is when chemicals and water are pushed through your heating system at a high pressure to push out any debris, dirt and blockages within your system.

This can only be done by a specialist plumber, and may require a days work. But at the end of the powerflush you will have a more efficient heating system and all of your radiators will be heating up and back to normal.

How do I stop a radiator from making a noise?

Noise coming from your radiator may be caused by trapped air in, try turning the radiator on fully at the valve to force any air out of the radiator. Failing this the radiator may need to be bled to release any air trapped within.
