Abstract
A system is provided for heat recovery from shower greywater. An outlet for greywater is connected to a heat exchanger's inlet for greywater and the heat exchanger is designed so that a cold supply water flows in the opposite direction through the heat exchanger relative to the relatively hot greywater, so that heat exchange works under a counterflow principle and heat energy is transferred from the hot greywater to the cold supply water. A manifold having a nozzle outlet for hot supply water is connected to a waste pipe so that the manifold nozzle outlet for hot supply water opens into the waste pipe at a position downstream of the waste pipe inlet for greywater but upstream of the waste pipe outlet for greywater.
