Water cycle heat pump  
 

With built-in Wilo pump, the series of heat pump can be connected to existing heating system at home directly. When you have a solar hot water heating system at home, the heat pump can be a back-up system for hot water without adjustment of the original system. Two kinds of system help you to save more. If you connect it to existing water tank at home directly, it makes a simple heat pump hot water system.
