The traditional place to position your radiator is the coldest part of the room. Whether that's beneath your window or against the wall. This is due to conduction, with incoming cold air causing more effective heat conduction and pushing the hot air from your radiator into the middle of the room.

Beside this, where is the best place to put a radiator in a bedroom?

The best place is in the coldest part of the room, usually under a window, as cold air creates better heat conduction (pushing the hot air from the radiator into the room). In double-glazed homes there may not be a cold area, so put them where they won't affect the use of walls.

Beside above, how far should a radiator be from the wall? 2 to 5 cm

Also, should radiators go under Windows?

While you no longer need to fit your radiator under the window, there is some logic in doing so. Historically, radiators were fitted in the coldest part of the room – the exterior wall – where cold air would enter and drop to the floor.

How many radiators should be in a room?

In most cases 1-2 radiators will suffice, however for larger rooms you may require more. The amount of BTU's required per radiator will depend on how many radiators are within the room – so divide the total BTU requirement by the number of radiators to calculate the average BTU's required per radiator.

Is it OK to put a sofa in front of a radiator?

Never put furniture in front of radiators - it will damage the furniture and stop the heat moving around the room. The same goes for curtains.

Do double radiators make a difference?

The main difference with a double panel convector radiator is that it can emit more heat, and quicker, than a single panel radiator. More efficient still is the double panel double convector, with two rows of parallel convector fins.

How much space do you need around a radiator?

The space required around the radiator so that there is no impedance on heat output due to insufficient natural air movement, is a minimum of 10% of the height of the radiator. In reality, it is aesthetically better to have at least 150mm around the radiator due to the protrusion of the thermostatic valve.

Can you tuck curtains behind radiators?

If your curtains hang over the radiator, tuck them behind. Don't have floor length curtains covering your radiator. They may look fabulous but you're wasting energy. Place heat reflective foil behind your radiator to prevent loss of heat through the walls.

Should curtains hang over radiators?


The rising hot air from a radiator meets the falling cold air from the window, which would otherwise collect on the floor of the room. Correctly fitted curtains should not cover the top of the radiator, but should stop just below the window ledge.

Are old radiators less efficient than new ones?

new radiators. Larger radiators are more efficient as they can run at a lower temperature and still heat the room sufficiently. Some older radiators may not be able to handle the output from your new boiler, especially if you are getting a combi or a larger boiler than you had previously.

What type of radiator gives out the most heat?

Central heating radiators
These radiators have the highest heat output and greatest heating efficiency of all plumbed radiator styles, making them a popular choice in many homes. They use corrugated panels (convectors) to radiate heat into the room.

Can you place a TV above a radiator?

You could always hang your TV above your radiator on a full motion wall bracket that can be pulled away from the wall to avoid the rising heat when the heating is on. When the heating is on you could just pull the bracket into the out position and when the heating is off you could fold back to the wall.

Are radiator covers a good idea?

Radiator covers with the proper backing can distribute heat more efficiently than an uncovered radiator. But more heat would be lost by blocking the convection upward with a cover, particularly if it is holding books or plants; you want the heat to go to the ceiling, that is how the radiator convects heat.

Does painting radiators reduce efficiency?


For painting the radiators to have any effect on the efficiency, it would need to lead to more heat escaping. It may make it slightly slower to heat your house, since it has to heat the paint first, but it won't make it less efficient - the heat still ends up in your house whether it goes via the paint or not.

Why are radiators put underneath windows?

Why are radiators placed under windows? In a room with single glazing, the reason it is more efficient to place the radiator under the window is due to conduction. On a traditional radiator most of the heat that comes from the radiator is emitted as hot air through the top of the radiator.

Can a radiator set things on fire?

Water radiators generally will not start a fire because they do not become hot enough. However, fragile materials placed close to or on a water radiator can burn.

Do radiator shelves stop heat?

A radiator shelf (yes, a shelf)
A radiator shelf just above a radiator helps to throw heat forward from the radiator into the room, rather than letting it rise up to the ceiling.

How much is it to install a radiator?

If it is beyond repair, standard radiator replacement cost ranges between $292 and $1193 for both the parts and labor involved in the installation. The average cost for radiator replacement will be near $671. The cost will vary significantly depending on your model of car and the complexity of the work involved.

Are tall radiators efficient?


Contrary to popular belief, vertical radiators work just as well as their horizontal counterparts. Science has shown vertical radiators are in fact just as efficient, with a 5000 BTU vertical working just as well as a 5000 BTU horizontal.

Do vertical radiators give out enough heat?

If your radiators are vertical, they won't give out the same heat output as horizontal radiators as they don't have the same length to draw cold air up for convection.

Should you paint radiators?

Yes, some lower cost paints could chip and peel over time, but most good quality emulsion paints can be used to paint your radiators. You just need to be sure you cover it over with a clear radiator overcoat after you've applied the emulsion.
