BOILERS AND STORAGE BOILERS

PUFFER COMBI

USE: The combined system of this flywheel-producer is made up of a receiver and a distributor of energy, produced by various traditional or alternative sources, directly or indirectly, through exchangers inside the flywheel. The hot water necessary to feed the different types of heating systems is taken from the flywheel. It will be at high temperature when the taking takes place in the upper part of the flywheel. It will at low temperature for radiant floor systems when the water is taken from the lower part . In this system, the preparer-storage tank for domestic hot water is inside the flywheel.
CONSTRUCTION:S235JR EN10025 quality steel sheets, assembled and welded with the use of automatic controlled atmosphere systems. Fixed spiral heat exchangers (depending on the models) with S235JR EN10025 steel pipes welded to the tank.
