What size convector radiator do I need?
The easiest way to work out what you need is to use our Heat Calculator. You can put in the dimensions of your room and various other pieces of information and you will be given the heat output you need in BTUs or Watts, the formal measurements of heat outputs.
All convector radiators on our website show their heat outputs in BTUs and Watts

What is the difference between single convector radiators and double?
While a single panel just has one part to it, a double panel radiator will have two equal sections with a grill in the middle called convector fins. These help increase the surface area of a double panel radiator to help it heat a room faster.
You can get more information on the different features a single and double panel radiator have from our blog by clicking here.
What is a radiator pipe centre?
You can then select a new radiator that has a Pipe centre measurement similar to the distance between your pipes. On all of our convector radiators suitable for a conventional hot water central heating system, you will see a ‘Pipe Centres’ measurement."
What type of radiator valves do I need?
We offer three types of valve – straight, angled and corner valves and which one you need depends on the position of your existing pipework in relation to the radiator.
To view exactly what we mean more clearly, please view our helpful illustration
We also offer the choice of non-thermostatic valves, which keep the radiator operating at a constant temperature, or thermostatic valves, which allows you to vary the temperature of the radiator they are installed on.
If you are purchasing an electric convector radiator, you do not need radiator valves.

Do your convector radiators come with wall fixings?
It used to be popular to install radiators under windows, however with modern double glazing and insulation this is now not always necessary, so you may wish to install your radiator elsewhere. In this case it is likely you will need to have changes made to your existing pipework, so please consult a plumber to discuss it first.
Can I install my convector radiator myself?
It’s preferable to hire a professional to install your radiator for you as this will ensure the job is done correctly and will possibly identify other issues you may not have been aware of.

Should I add chemical inhibitor to my convector radiator?
With hot water constantly running through your central heating system, there can be a chemical reaction between the water and the metal of your pipework or radiators which can quickly cause erosion inside your system. This can result in small pieces of metal breaking off into your system, causing radiator sludge, placing strain on your system and stopping your radiators heating up properly.
Simply adding chemical inhibitor can dramatically reduce this process and keep your heating system running smoothly.
To see what happens when you don’t add inhibitor to your system, please see the video below

What should I use to clean my convector radiator?
Hot radiators attract dust, so you can use a vacuum cleaner to remove excess dust front the panels, convector fins and grills.
When wiping down the radiators, please use a soft cloth and warm water with a small amount of washing up liquid. Do not use an abrasive brush or household detergent as this could damage the finish.
