The Kensa pond mats are specifically designed to ease installation while maximising the energy absorbed from the water. The pond mats can be weighted and sunk to the bottom of the water source or attached to the underneath of a floating pontoon. Approximately 250m of pipe is secured to a corrosion resistant stainless steel frame. This frame can then be weighted down on site to enable them to sink to the bottom of the water source. The ideal water source has a constant water flow into and out of it, which means the energy held within the water is continually replenished.
The benefits of using a closed loop system in water over an open loop system include a reduced risk of freezing within the heat pump and reduced maintenance as there is no need for any filtration units.
