Drawing off hot drinking water from heating installation - involves two separate circuits with pressurised fresh cold water supply to secondary circuit

摘要

The arrangement is for drawing off hot domestic water of drinking quality from a heating installation with one or more heat sources and a hot water container. An intermediate container (12) has a connection (22) for drawing off the water, combined with a circulation pump (16) and a heat exchanger (5). These together form a circuit (20) in a predetermined directional flow. There is a constant connection (15) for fresh cold water under pressure in the circuit. The hot water container (1) forms a second circuit (10) with the same heat exchanger (5) and a second circulation pump (6). A control circuit (25) is activated by signals from a flow recorder (26) and a thermometer (27) controls the pumps (16, 6). USE/ADVANTAGE - A simple and convenient hot water arrangement in a house can supply drinking quality water.
