The EXIT swimming pool heat pump is an alternative for heating up swimming pool water. The heat pump turns the outside air into heat and is already effective with an outside temperature of 10 degrees. The transferred heat can then be used to heat up the swimming pool water up to 40 degrees. The EXIT heat pump can easily be connected to the swimming pool and the filter pump with simply two tubes. One tube connects to the filter pump and the other one to the swimming pool. The EXIT heat pump for swimming pools is straightforward to operate by means of a digital screen to set the desired water temperature. The pump will turn off when the water has reached the set temperature and will automatically turn on again when the water reaches a lower temperature than programmed. This way, the pump only consumes energy when needed.
