Heating system e.g. for disengageable main heating system, has heat source such as solid fuel boiler, and second heat source such as oil burner and consumer

摘要

The system has a heat source (1) such as a solid fuel boiler, a second heat source (2) such as an oil burner and a consumer (5). A memory (3) is provided having a lead line (31) and a return line (32) and a CPU (6) with two mixing valves (13, 14). The first valve is compounded in a first position with a first-connection line (30) or in a second position has a backward-connection line (40). The first pre-connection line is compounded with the second valve in a first position with the second-connection line (10) or in a second position with the return line (22) of the second heat source.
