Abstract

Heat recovery system (3) and a shower comprising such a system. The heat recovery system comprises a waste water 5 discharge line (ll) and a heat exchanger (15) with at least one waste water channel (23) and at least one fresh water channel (24) in heat conductive connection with the waste water channel. The heat recovery system further comprises a reservoir (9) for collecting waste water. The discharge line 10 has a lower end in open communication with the reservoir and a pump (13) for pumping water upward from the reservoir via the waste water channel(s) of the heat exchanger.
