ABSTRACT:
A heat pump with a compressor arrangement whose condenser forms a heater for water, and whose evaporator is arranged to be heated by air which by means of a fan in a fan space is blown through the evaporator. An air path for ambient air or an air pass for room air is connected alternatively to the fan space. A control means is arranged between the fan space and two air passes for selective connection of one or the other air pass to the fan space, and with the control means in a first position, the fan is arranged to blow air through an air path with ambient air and through the evaporator for water heating, and with the control means set in another position, the fan blows air through another air path with room air and through the evaporator.
