Purpose and goal

The purpose of developing the PMX system has been and is to put an end to the huge excess consumption of water that occurs in older buildings that lack circulation on their tap hot water. The consequence is that hot water is cooled down when no tap occurs in the system. When people need hot water, the cold water is flushed into the drain. The global over consumtion that happens every day means that hundreds of billions of liters of water are flushed into the sewers every year.

Expected results and effects

A final solution has been achieved. The system has the capabilities of on one global market saves hundreds of billions of liters of water annually. The PMX system contributes to increased comfort for residents, eliminating the risk of legionella bacteria developing and, of course, lowering the costs of water and sewage.

Planned approach and implementation

The development of the PMX system has been going on for over 2 years and extensive work has been done to find the optimal technical solution. We believe we have achieved that goal. The PMX system is easy to install, reliable and with a short pay off time.
