Earth Save - Swimming Pool  heat pump

Working Principle: The purpose of a swimming pool heat pump is to absorb the heat from natural air and then transfer it into pool water or to take heat out of the pool to cool it.

The unit is powered by electricity and will deliver a COP of almost 5, making then among the most efficient units on the market.  The units are all designed for location close to a pool (stainless steel cabinets are available, if required) and have titanium heat exchangers, providing years of trouble free use.   Even the screws in our units are stainless steel, making them extra durable.

Duratech Heat Pump

Duratech - Swimming Pool  heat pump

Duratech heat pumps utilize the sunís 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 becomes a gas. The warm gas passes through the compressor where it is compressed to form a very hot gas, which in turn then passes through the condenser (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 condenser coil, returns to its liquid form and, after passing through the expansion valve, the whole process begins again.
Energy Chart Cost Comparison Chart
For each kW consumed by the Duratech heat pump, 4 to 5 kW are returned to the pool.


Duratech heat pumps are less harmfull to the environment because 80% of the energy produced is collected from the outside air and thereby purely natural. Also the gas used R407C, has no harmful effect on the ozone layer.
