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.

Correspondingly, how far off the floor should a radiator be?

Vertical radiators come in many sizes, but typically 1800mm high and 600mm long. Typically, standard radiators are mounted so that the bottom of the radiator is 150mm from the floor. The governing factor from an aesthetic point is the height of the skirting boards that will be present.

Also Know, where should a radiator be placed in a house? 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, why should a room heater be kept on the floor?

HEATER is placed near the floor because hot air rises up and the room will be heatness will spread even. The density of air depends upon the temperature. Hence, heater is placed near the floor because the air currents move upwards so the hot air fills up the whole room.

Is a radiator better under a window?

As described in the other answers, putting the radiators (or hot air vents in a forced-air system) under the windows offsets the greater heat loss of the windows, but there is another reason. As room air flows over the surface of a window, it will lose heat to the window (and the outside).

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.

How high should a radiator be from the floor UK?

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

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.

Are all radiator brackets the same?

Examine your brackets
The two brackets are the same, there is not a left and right. However, each has a large side and a small side. You should hang the radiator from the large side as this holds the radiator further out from the wall giving you better air current and heat flow.

What is a standard radiator size?


3: What Size Radiator Do You Need?
Single panel single convector Double panel double convector
Height (mm) Width (mm) BTU
600 600 3745
600 700 4370
600 800 4994

How high should a towel radiator be from the floor?

The bottom of the towel warmer should be located 36-inches from the floor to prevent leg and foot burns.

Can I put a vertical radiator behind a door?

In some instances, particularly in smaller rooms, positioning a radiator behind a door may be your only option. Since radiators move heat around the room via convection, positioning the radiator here shouldn't be a problem. However, this depends on the temperature of the space that the door connects to.

Why air conditioners are never installed near the floor of the room?

Originally Answered: Why is an air conditioner never place at the floor of a room? That's because cold air sinks and warm air rises. These type of units work by mixing the cold supply air with the room air at high level to attain the desired temperature before the air reaches our body level.

Why the heater is fitted at the bottom of the tank?

Most convective heating devices are kept at low levels in the space because they function by warming air, which rises due to lower density and is replaced by cooler air moving along the floor.

Why are air conditioner installed near the ceiling of rooms?


Answers and Solutions
Answer: this is because, when it is installed at a height it cools the air that is closer to the ceiling first and as we know hot air rises up because of lower density, the cool air comes down making the room cooler. this not only helps in cooling the room fast but also helps save elctricity.

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.

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 it matter which way round you connect a radiator?

A normal radiator or towel it doesn't matter. If the radiator is not fitted, then the tails will not heat up. Fit the radiator, if it's the wrong way round, all you have to do is swap the rad valves round - I think the instructions will just be referring to the TRV's, nothing to do with the radiator itself.

Can a radiator be too big for a room?

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.

Will a double radiator make room warmer?


The longer the panel, the larger the heat emitting surface area, so bigger radiators will emit more heat, but also remember that a double panel radiator will emit more heat than a single panel radiator of the same length.

Do you need a radiator in the hall?

Radiators can be found in every room in the house. Unlike the living room or the kitchen, the hallway has no function other than to get you somewhere else, much like the roads of a property. They are a means to an end, not a destination.

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.
