How to buy a radiator

There’s a lot of factors to consider when buying a radiator. The room it’s intended for, its suitability for your decor and the heat it needs to provide are all important factors.

To help, we’ve put together a guide to buying radiators online or in person in six easy steps.

1. Confirm your heat output requirements

Please use our Heat Output Calculator for a quick guide. However, we recommend you check outputs with your installer before making a purchase. 

It is essential you know how much heat you will need as this will determine the size of your radiators.

2. Choose your design

Select from over 52 exclusive and affordable designs. 

Our range has everything from traditional cast iron and steel radiators to modern feature radiators. We even sell an environmentally-friendly aluminium range

Each of our stylish radiators comes in an extensive choice of sizes, colours and outputs.

3. Choose the colour you want

With over 230 colours and special finishes you are able to match your colour scheme or introduce an accent colour to create a striking feature. 

To help choose your colour most products belong to a colour group shown in the overview section of each product.

You can also look at all our colour groups within the finishes page where you can see all colours and products available in each group.

4. Find a Valve

To complete the look choose from our wide selection of radiator valves and add any accessories that complement your choice. We recommend using TRV valves in all living rooms and bedrooms to maximise the efficiency of your radiators. 

Please remember valves will increase the overall width of your radiator unless you select underneath (B2) connections.

5. Order online or from your nearest showroom

It’s easy to buy your radiator online with The Radiator Company. Simply browse our range, choose the size you require and add it to your basket. 

Once you’ve added everything you need, simply head to your shopping cart and checkout, where you can make your payment and add delivery details.

If you prefer, you can also use a local merchant or find a showroom near you to browse our range in person.

What is BTU? The BTU rate of a radiator is how much heat the radiator will emit, and is there to help you decide if a radiator is the correct size for your room or not. It’s important to know how much heat your room needs in order for your system to work efficiently.
