Solar water heater control method

摘要

The method involves recording the temperature of the water flowing to the solar collector (1). When a prescribed difference between the temperature of the water flowing in and out of the collector is recorded, the water flowing into the solar collector is fed directly to a primary heat exchanger (35). This heat exchange is heated by a burner (36). When a prescribed higher positive difference in these temperatures is exceeded, all the water is directed through the collector.
