Control process for hot-water heating in heating system

摘要

The process applies to a heating system with a heating boiler and a hot-water heater combined with the hot water tank. The switching off of the burner occurs not when the required hot water temp. (TS) is reached, but at a lower switch-off temp. (TA). This is set sufficiently below the required temp. for the required temp. to be reached during the running time of the tank filling pump by further energy transfer from the water in the boiler to the hot water for consumption. This prevents the water running out too hot.
