Central- and washing-water-heating control system - regulates flow through washing-water heat-exchanger dependent on medium temperature

摘要

The flow through the primary side of the exchanger, and/or of the washing water through the secondary side, are controlled dependant on the temperature of the heating medium. This is done by a thermostat valve (10) in series with the secondary side (30) of the exchanger (2) and the draw-off point (3). This is controlled by the temperature of the medium in the central-heating circuit. It is also provided with a drive (32) which is connected to a control switch (15) wit a sensor (17) in the flowing medium. ADVANTAGE - Reduces heating-up time, even if flow through primary side is not continuous.
