DURATECH® Heat Pumps

Irrigation UK are suppliers of Dura + & Duratech Heat Pumps & Exchangers

Coming soon the DURATECH® heat pump, the ideal solution for heating your swimming pool or spa.  

The DURATECH® heat pump must be installed outside. It will heat the pool from April to October and will even work with outside temperatures as low as -5°C. A cooling mode allows the water to be cooled down by the DURATECH® heat pump as well. DURATECH® heat pumps are less harmful to the environment because 80% of the energy produced is collected from the outside air and therefore purely natural. Also the gas used, R407C, has no harmful effect on the ozone layer.

DURATECH® heat pumps are constructed for duribility and longevity - Using advanced and high quality materials like PVC and "Duranium® for the heat exchanger means it can resist erosion from Chlorine etc in the water. Also the Duranium® heat exchanger is oversized to improve efficiency.　

DURATECH® heat pumps utilize the sun’s free heat by collecting and absorbing energy from the outside air. This energy is then transferred to the pool water. Your existing pool pump circulates the water through the heater and warms the pool. The unit contains a fan that draws in outside air and directs it over the surface of the EVAPORATOR (energy collector). The liquid refrigerant within the EVAPORATOR coil absorbs the heat from the outside air and the refrigerant becomes a gas. The warm gas passes through the compressor where it is compressed to form a very hot gas, which then passes through the CONDENSOR (water heat exchanger). It is here that the heat exchange occurs as the hot gas gives up the heat to the cooler swimming pool water circulating through the coil. The pool water becomes warmer and the hot gas is cooling down as it flows through the CONDENSOR coil, returns to its liquid form and, after passing through the expansion valve, the whole process begins again.
