WATER HEATING PROCESS AND WATER HEATING DEVICE

Abstract

The present invention relates to a process for heating water to regulate a water storage temperature in a storage unit (12C) by means of a hot water generation unit (14C), in particular a heat pump, wherein the power of the hot water generation unit (14C) is regulated. In a process step, the power of the hot water generation unit (14C) is regulated based on the difference between the storage temperature and a reference temperature, whereby if the difference between the storage temperature and the reference temperature decreases, the power of the hot water generation unit (14C) is progressively and / or continuously reduced.
