Method for saving energy in central heating and hot water systems uses individual time relays near each hot water tap which switch on water pump with preset delay, heat, light or motion sensors connected to pump over-riding relays

摘要

The method for saving energy in central heating and hot water systems uses individual time relays (1 - 4) near each hot water tap which switch on the water pump (50) with a preset delay. Heat, light or motion sensors connected to the pump over-ride the individual relays automatically.
