Energy-saving central heating system has solar collectors for sole heating during the supper, heat pumps for winter operation, and resistance heating system

摘要

The arrangement has solar collectors and heat pumps. The collectors (10) supply heat energy to a central heating system via a heat exchanger (20), a regulator (30), and a heat pump (60). A resistance heating system (100) is connected behind the arrangement. A geothermal energy exchanger is switched parallel to the solar collectors.
