DEVICE FOR RECOVERING HEAT FROM WARMED HOUSEHOLD DRINKING WATER

摘要

The aim is to achieve, without using a heat pump, heat recovery, which operates simply, with low maintenance and without energy, from if possible all types of hot waste water occurring in the household, after these have been separated from the cold waste waters, it being the intention that the possibility should also still exist of using the waste water subjected to the heat recovery as toilet flushing water. This is achieved in that the tank is designed as a distributor tank and equipped with an inner wall filter and in that the outlet leading into the waste water duct can be shut off by means of a shut-off member via a solenoid valve and a temperature sensor measuring the water temperature in the distributor tank and in that the distributor tank has a second outlet, via which, above a given adjustable temperature, the waste water cleaned by the inner wall filter can be led off into a second pipe into a heat exchanger tank and in that the heat exchanger tank is connected via an overflow pipe to the waste water duct and has a heat exchanger pipe coil, through which cold drinking water is conducted, which can be supplied via a third pipe system to the consumer points of the household on the one hand and via a fourth pipe to a boiler on the other hand, the boiler being connected via a fifth pipe system to the individual consumer points of the household and there being connected, where applicable, to the overflow pipe of the heat exchanger tank a waste water collecting tank which is connected via a sixth pipe to the toilet cistern so that the drinking water consumption in the household is also reduced hereby in that fresh drinking water is not used for the toilet cistern.
