METHOD FOR SAVING ENERGY AND HEATING SYSTEM WITH PRODUCTION OF DOMESTIC HOT WATER USING THE SAME

摘要

The yield of the boiler 2 is improved by cooling a branch pipe 7 for returning the heating fluid, before entry into the main bundle 1 of the boiler, by heat exchange 4 with the additional mains water 6 injected into the hot water circuit 19, 18, 20, then preheating in a complementary bundle 5 of the boiler, only when the boiler consumes energy.
