Clivet's WLHP (Water Loop Heat Pump) is widely used in shopping centers, office buildings, hotels and in the most different climatic conditions. Clivet has developed and improved these solutions over the years, even acquiring the English VERSATEMP brand.

The system is based on a hydraulic circuit (ring/loop).The water flows pushed by pumps and in typically "neutral" conditions with refernce to the environment (20-30°C), which acts as a source for energy producers formed by water-air or water-water heat pumps The loop circuit allows efficient transfer of energy between zones with opposite needs (heating/cooling) and activates the dispertion or integration systems only when the temperature of the water tends to stray from the optimal operational interval.

The WSHP system (Water Source Heat Pump), system variation of WLHP, is based on heat pumps which use sea/river or lake water as a renewable energy source. The heat pumps are connected to one another by one or more closed loop circuits with energy transfer and provide the cooling or heating capacity needed to maintain the desired comfort conditions
