How to Select a Radiator

Hot Tips

Radiator Placement

Radiator Placement

The first thing to consider is whether you want to match your existing radiator size and position or to place new models elsewhere. Moving them will require reconfiguring pipework, which could involve removing floorboards and/or plaster – this is quite common for whole room refurbishments but may be more involved if you are just replacing the radiators. Our range of stock models has been carefully selected to accommodate both requirements.

Traditionally radiators were placed under windows as this helps to counteract any cold downdraughts and prevent condensation, plus which this position is often unobtrusive. However, with double glazing and modern levels of insulation it is easily possible to locate your radiators away from the window in the position you decide is most pleasing aesthetically. Tall slim radiators can be installed in areas which are otherwise unusable and can also make a great feature. Removing radiators from under windows also allows for floor length curtains to be used.

For large areas of glazing, which may be prone to condensation, consider using low level radiators such as our Flow Form.



Manual valves: these have no labelled settings. Simply turn the valve head until the radiator is giving out the amount of heat desired. They are most suitable for use in rooms where your heating needs will be fairly constant e.g. for towel radiators in bathrooms, or where the preference is for a more subtle and discreet appearance.

Thermostatic valves: these come with an inbuilt temperature sensor and have a range of temperature settings. The thermostatic valve will maintain the room at the temperature you have selected,by automatically adjusting the heat output from the radiator. This helps to save energy as it means that you can take advantage of any "free" heat the room receives, such as from the sun or electrical items. Thermostatic valves are especially useful for rooms that may have large changes in occupancy or use e.g. open plan kitchen/diners.

When deciding which valve set to use with which radiator, you will need to consider where the heating pipes are coming from i.e. the wall or the floor.



Poor pipework installation can spoil the final look of your lovely new radiator. However this can be easily avoided by planning the pipework with your plumber beforehand. Some solutions may cost a little more but are well worth it in the long run.

If you’re placing the new radiators in the same position as old ones then chose a length which is as close as possible to your existing ones so that the pipe connections are the same. If this isn’t possible, then discuss with your installer how the pipework can be made to look as neat as possible (this can be simple as careful readjustment of floorboards). Or consider ordering a bespoke size that will fit exactly - delivery times will be longer but the lasting appearance will be much improved.

Often central heating pipes come from the floor and connecting these to a tall, vertical radiator, which is positioned higher up the wall, can result in unattractive lengths of pipework. One alternative is to sink the pipework into the wall as you would with electric cables. Your plumber may charge you a bit more for this but the end result should be worth it. For shorter lengths (under 300mm) consider using our chromed pipe and shroud kit.
