Where is the best place to put a radiator in a bedroom?

Last Updated: 23rd April, 2020

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.

Hereof, how far should a radiator be from the wall?

The distance from the wall to the radiator should be from 2 to 5 cm. In some cases, the wall surface must be coated with special heat-reflecting material before installing the radiator.

Beside above, 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.

Besides, 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.

Where should you place radiators in a room?

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.

Can vertical radiators be horizontal?

Vertical Radiator Benefits
Vertical radiators can be fitted in any room and bring a different heating experience to the home. You can utilise more space in smaller homes with vertical radiators as they can be installed on walls that aren't wide enough for horizontal radiators and still effectively heat the home.

Why are radiators placed near the floor?

When cold air enters the room, it falls to the floor and moves across the room, which is felt as a draught. A radiator placed under a window counteracts this effect and warms up the cooler air, so preventing the draught progressing into the room.

How high should a radiator be from the floor UK?

Recommended height from the floor to the base of the radiator is 150mm minimum.

Should a radiator be level?

In a steam system it is important that the radiators be level - or they can slope very slightly toward the inlet valve through which the steam enters. Just as radiators must drain easily, so too must pipes in a steam system be pitched slightly so all of them slope down toward the boiler.

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.

Can you put a sofa in front of a radiator?

For example, if you have sofas or chairs in front of radiators, then this will block much of the heat from reaching the rest of the room and it will take much longer for the room to heat up. Even just moving the sofa away from the radiator a few inches can help.

Can curtains catch fire from a radiator?

The water circulating in those “radiators “ is at about 70 degrees Celsius, and will not put anything on fire. The main objection to having long curtains hanging over the radiator,is that it either reduces the convection airflow,or directs it away from the room and up a window.

Why are radiators always placed under Windows?

Why are radiators placed under windows? This interacts with the cold air from the window, and this cold air then helps push the hot air from the radiator into the room. This in turn keeps the room warmer than it would be if the radiator was in a different location.

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.

Can a radiator start a 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.

Should curtains go over radiator?

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.

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.

Should long curtains touch the floor?

As a general decorating rule, drapes should be long enough to touch the floor. The amount of drapery material reaching the floor depends on the desired look of the curtains once they are hanging around the windows.

Do double radiators make a difference?

Single panel convector radiators will emit less heat than their double counterparts, due to only having one long panel that sits against the wall, whereas with a double panel, two panels will sit on the outside of the convector fins. This essentially means there is less of a surface area for heat to come from.

How do I work out what size radiator I need for a room?

To effectively calculate what the BTU output for any room is, you have to start by getting a tape measure and measuring the height of the room, the width of the room, the length of the room and then finally the size of the window area (that's the length by width of a window in m²).

Can a radiator be too big?

A radiator that is not powerful enough will not be able to heat the room adequately, but a radiator that is too big will not only overheat the room but will cost you unnecessary money to run. A radiator's size (or power) is measured in BTUs.

How many radiators will a 30kw boiler run?

As a rough guide most apartments and smaller houses, with up to 10 radiators will require a 24-25kw boiler. A 28-30kw would be installed for a medium to large 3-4 bed house with up to 15 radiators, and a 33-35kw and a 40kw would be for a large house with anything up to 20 radiators.
