Also called Absorbermatte, used primarily for heating pools and swimming pools, absorber mats made of rubber have vulcanized connections for the supply and discharge. The rubber must be heat-resistant up to 120 degrees C, permanently elastic and withstand cold. No control and memory components are required here. The absorber surface should be between 50% and 80% of the
be large to be heated water surface. The system can be installed on the ground, in case of lack of space and, if the statics permit the weight, also on a roof. Temperatures of 50 degrees C are achievable.
If plastic collectors are to be used for DHW production, which of course is also possible, they must be connected to a storage tank.
