It is not possible to install tall radiators everywhere. In many rooms, low window radiators are the right choice and 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 window radiators for use in rooms with sloping ceilings or attics?

Dimensions of low window radiators
Regulus under-window radiators can have various dimensions. You can choose from models ranging from 40 to 200 cm in length and from 9 to 18 cm in thickness. The lowest radiators can be only 12 cm high and, including the legs, 20 cm high. The under-window radiator may have different efficiency depending on the dimensions and the fan used - 24 V or 230 V. You can choose not only radiator models mounted on legs, but also those mounted on hangers. If the window sill is located low, the only choice is a low under-window radiator if no channel radiator was planned at the stage of building the heating system.
Why are radiators usually mounted under windows?
The radiator installation location should allow for effective heat distribution and therefore have good air circulation. This exists under windows and sills. Efficient circulation of warm air compensates for the 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 finishing it with a material that will not quickly get dirty after one or several heating seasons.
Window walls are the coldest element of the house, even if their surfaces are well insulated, so installing radiators in this place is absolutely necessary. The choice of the place from which the heat spreads is very important because it can be distributed evenly. The radiator under the window acts as a kind of thermal curtain for the cold air from outside. The radiator should be mounted 10 cm from the floor and windowsill and 3-4 cm from the wall.
Low copper-aluminum radiators, perfect for the attic
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 deserves attention. This radiator is perfect for low-temperature heating systems using condensing boilers or a heat pump. It is characterized by resistance to variable and high pressure. Heat is emitted through radiation and convection, which ensures effective operation. Such a radiator quickly reaches full power.
The thermal power is 684 W at standard operating parameters. It is worth knowing that the heat demand in homes ranges from 60 to 200 W/m2. It depends on the method of insulation. In well-insulated houses it is 0.3 W/m2K, and in less insulated houses - 0.7 W/m2K. In turn, in houses without insulation, the heat demand ranges from 1.2 to 1.5 W/m2K. The above radiator can be adapted to an installation operating at 75/65 degrees Celsius, i.e. a supply temperature of 75 degrees, a return temperature of 65 degrees and an indoor temperature of 20 degrees Celsius.
A good choice for the attic may also be the Regulus SOLLARIUS S4/140 copper-aluminum radiator with side connection . It achieves a thermal power of 1771 W at parameters of 75/65/20 degrees Celsius. Therefore, it will be suitable for a larger, well-insulated room with an area of approx. 25 m2 or a smaller and moderately 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 spaces in the attic, e.g. a loft , the Regulus SOLLARIUS S4/200 copper-aluminum radiator with side connection may work well. This model has a thermal power 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 matched to any room due to its universal colors. You can order it not only in the standard white color but also in any color from the RAL K7 palette - at no extra charge.
You can choose from feet for mounting to the floor or hangers for wall mounting, included in the price. It is also worth paying attention to the compact bottom-fed Regulus DUBEL DSD4/60 radiator, 18 cm thick. Its power for the 75/65 °C system is 1159 W. It is perfect not only for attics, mounted on wall hangers, but also anywhere as a free-standing one, attached to the floor using mounting consoles. It can be used in any type of installation: copper, plastic or traditional steel. 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 windows, low window sills, or under benches (tribunes).
