It is not possible to install tall radiators everywhere. In many rooms, low under-window radiators are a suitable choice, which can be very efficient. It is worth paying attention to the offer of the manufacturer Regulus available in the Onninen installation wholesaler . What is worth knowing about low under-window radiators for use in rooms with sloping ceilings or in attics?

Dimensions of low under-window radiators
Regulus window radiators can have various dimensions. Models from 40 to 200 cm in length and from 9 to 18 cm in thickness are available. The lowest radiators can be only 12 cm high, and with legs 20 cm. A window radiator can have different efficiency depending on dimensions and the fan used - 24 V or 230 V. You can choose not only models of radiators mounted on legs, but also those that are mounted on hangers. If the windowsill is located low, the only choice is a low window radiator, when a duct radiator was not planned at the stage of building the heating system.
Why are radiators usually mounted under windows?
The radiator's mounting location should allow for effective heat distribution, and therefore have good air circulation. This exists under windows and window sills. Efficient circulation of warm air compensates for losses associated with mounting the radiator on an external wall. It is also worth ensuring that the wall is properly insulated before installing the radiator and that it is finished with a material that will not quickly get dirty after one or several heating seasons.
Window walls are the coldest part of the house, even if their surface is well insulated, so installing radiators in this place is absolutely essential. Choosing the place from which the heat radiates is very important, because it can be evenly distributed. A radiator under a window is a kind of thermal curtain for cold air from outside. The radiator should be installed 10 cm from the floor and windowsill and 3-4 cm from the wall.
Low copper-aluminum radiators ideal for attics
Low under-window radiators made of copper and aluminum are a great choice for the attic. It is worth getting to know the offer of the Regulus manufacturer and choosing the right radiator for the surface of the room and the location of the wall on which the window is located. Among the low aluminum radiators , the Regulus SOLLARIUS S2/100 copper-aluminum radiator with side connection is worth attention. Such a radiator works great in low-temperature heating systems using condensing boilers or heat pumps. It is characterized by resistance to variable and high pressure. Heat emission takes place through radiation and convection, which ensures efficiency. Such a radiator quickly reaches full power.
Thermal power is 684 W with standard operating parameters. It is worth knowing that the heat demand in homes is from 60 to 200 W/m2. It depends on the insulation method. In well-insulated homes it is 0.3 W/m2K, and in less insulated homes - 0.7 W/m2K. In turn, in homes without insulation the heat demand is from 1.2 to 1.5 W/m2K. The above radiator can be adapted to an installation operating in the parameters of 75/65 degrees Celsius, i.e. supply temperature 75 degrees and return 65 degrees and temperature inside the room 20 degrees Celsius.
A good choice for the attic may also be the Regulus SOLLARIUS S4/140 copper-aluminium radiator with side connection . It achieves a thermal output of 1771 W with parameters of 75/65/20 degrees Celsius. It will therefore work well for a larger, well-insulated room with an area of approx. 25 m2 or a smaller and medium-insulated room, e.g. 10 m2. Like the previous radiator, it works well in low-temperature systems and cooperates with a heat pump or condensing boiler.
For large attic spaces, e.g. loft type , the Regulus SOLLARIUS S4/200 copper-aluminum radiator with side connection may prove useful. This model has a thermal output of up to 2642 W for a system operating at temperatures of 75/65 degrees Celsius. The depth of 90 mm means that the radiator does not take up much space, and the length of 200 cm with a height of 39 cm guarantees effective heating of a larger space in the attic. The radiator can be adapted to any room due to its universal colors. It can be ordered not only in standard white but also in any color from the RAL K7 palette - at no extra charge.
A choice of floor-mounted legs or wall-mounted hangers included in the price. It is also worth paying attention to the compact Regulus DUBEL DSD4/60 bottom-fed radiator with a thickness of 18 cm. Its power for a 75/65 °C system is 1159 W. It will work perfectly not only in attics, mounted on wall hangers, but also anywhere as a free-standing unit attached to the floor using mounting brackets. It can be used in any type of installation: made of copper, plastic or traditional steel. It works with solid fuel and condensing boilers and heat pumps (very large heat exchange surface). These models are used not only in single-family buildings but also in large public interiors, under large display windows, low window sills or under benches (stands).
