Swimming Pool Heating

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 swimming 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.

The integrated microprocessor monitors all the sensors and controls the device without any intervention of the user. Electronic display and control with easy operation is standard.

The use of a high efficient, low sound rotary or scroll compressor, a low noise fan and an oversized heat exchanger, makes the unit to be extremely quiet in operation.

The VA-WPH series class leading air source heat pumps for swimming pool heating are the most efficient and reliable swimming pool heat pumps available, built to the highest possible standards.

Clean, efficient and ecological, they use State-of-the-art technology, using the highest quality components to ensure ultimate performance and reliability.

Key Features:
* Titanium heat exchanger - total protection against corrosion.
* State of the art Digital Controller can run the filter pump independantly.
* Zero corrosion defect - 15 year guarantee on heat exchanger.
* Reverse cycle defrost (means it can be run at very low temperatures, -10degC).
* Rotary and scroll compressors - sanyo & Hitachi - efficient reliable and silent.
* Whisper quiet fan (plastic, no corrosion) - low speed, tuned for maximum airflow and minimum noise.
* Large evaporator - enables higher performance / COP than side entry fan Heat pumps.
* Soft Start as standard on model 40 upwards - means no problematic spikes in input power when starting.
* Digital control state of the art, easily programmable with full diagnostic display.
* SIM card - option to remotely control the heat pump from anywhere in the world.
* Low carbon emmissions therefore reducing your carbon footprint - classed in the "renewable energy" category.
