PRANA water-water heat pumps use water as energy source and use it for heat transfer to the environment
Rivers, ponds and also the sea are all important energy sources. Thanks to the property of water to maintain a constant temperature, PRANA water heat pumps ensures the highest performances whilst reducing the energy consumption up to 50%.
In this system the exchange of heat is possible thanks to two wells, one for the water extraction and the other for draining. Simple in design and operation but able to provide a significant number of advantages, these ground water systems are highly efficient, even if they have some prerequisites.
First of all, installers need to observe local laws and regulations on the extraction capacity and the temperature variation of the water that returns to the soil. The distance between the dewatering and immersion wells should be at least 10-15 m and the characteristics of the water must accurately follow the technical instructions included in the technical bulletins and manuals.
Furthermore, it is extremely important that the amount of water is enough; this can be easily calculated before the system is installed.
