Diffusion of heat can be ensured by different types of heating emitters. Underfloor heating is an increasingly popular emitter for its many advantages, but it is possible that the installation of a heating floor in your home is too complicated.
Discover in this article an alternative solution equally effective but easier to implement in renovation: the heating ceiling.
What is the function of the ceiling heating?
The operation of the heating ceiling is similar to the operation of the heated floor. There are two types of ceiling heating: the electric radiant ceiling and the hydraulic ceiling.
The electric radiant ceiling
There are two types of radiant ceiling:
– The Modular Radiant Ceiling (PRM), consisting of heated modules assembled and attached to a metal structure fixed to the ceiling.
– The radiant ceiling plaster (PRP), made of a heating film integrated in an insulating panel fixed on a metal frame.
The assembly is then covered with special plaster plates. The electric radiant ceiling, whether modular or gypsum, works by radiation. It produces heat that is diffused into the room.
The hydraulic heating ceiling
This system, powered by a boiler or heat pump ideally, consists of a network of hydraulic tubes fixed to the ceiling and operating in a closed circuit.
It is more expensive than the electric radiating ceiling but allows to regulate the temperature of the housing according to the outside temperature as well as the ambient humidity rate.
Efficiency of ceiling heating
Ceiling heating is just as effective as underfloor heating.
To guarantee the quality and comfort of this solution, it is strongly recommended to have a good insulation of the whole housing, thanks to insulating panels (glass wool for example), in order to limit the loss of heat.
What are the advantages of the heating ceiling?
The heating ceiling has similar advantages to underfloor heating, but with some additional positive points.
– First of all this heating equipment ensures optimum comfort since it diffuses a warm and homogeneous heat in all the rooms.
– This heating system does not encounter any obstacle to the diffusion of heat (carpets, furniture, etc.). It is therefore very reactive: in less than 30 minutes, the heat diffuses and the room is heated to the desired temperature. This saves money on energy consumption.
– This solution of heating by the ceiling is also aesthetic since the absence of radiators saves space. With a thickness of 10 centimeters, the installation reduces very little the ceiling height of the rooms.
– Unlike underfloor heating (advantages / disadvantages of underfloor heating), which has contra-indications concerning the coating, this solution leaves the possibility of choosing any floor covering.
– This ceiling heating solution requires no maintenance and is suitable for new as renovation.
Moreover, the hydraulic heating ceiling is a reversible solution offering the possibility of refreshing its housing for more comfort in summer. It ensures a thermal comfort of your accommodation all the year.
What are the disadvantages of ceiling heating?
Although the advantages of this solution are numerous, there are also some disadvantages to be taken into account.
– First, the heating ceiling requires a minimum ceiling height of 2.40 meters to avoid the risk of overheating. This minimum height is also recommended to maintain a proper ceiling height after installation which reduces the height by about 10 centimeters.
– But the main disadvantage of this solution is the cost of the installation, which is higher than that of underfloor heating.
