Why Choose an ITS Brand Pool Heat Pump?

A heat pump works like an air conditioning unit in reverse. It extracts heat from the ambient air surrounding it, enabling it to heat the refrigerant which is then compressed causing it to get even hotter. This is then run through a heat exchanger in which the water is heated. The refrigerant is then allowed to expand again, thus cooling it down and enabling it to again absorb heat from the surrounding air. So only a little electricity is used to run a fan and compressor while the heat energy is provided indirectly by the sun.

The modern pool heat pump is a very efficient water heating device which uses a small amount of electricity to drive a compressor which forms the heart of the heat pump. The heat energy produced can be more than five times the electrical energy used to drive the compressor on standard on/off models and more than ten times for inverter technology units. This means that your electricity consumption for pool heating can be divided by up to ten when compared with normal electrical element heating.

The heat pump is not reliant on sunshine or direct radiation but extracts heat energy from the air at any time of the day or night and so is effectively a solar heater in a different form. Even in extremely cold conditions (-5°C and lower) the heat pump can still provide a saving of more than 60%. In most cases in South Africa, where our daytime temperatures are relatively high, the efficiency is going to be at least 5 x that of an element heated water system. A heat pump looks similar to an air conditioner and can be installed either on the ground or on brackets on a wall. It is quiet and unobtrusive with a user friendly controller, has no greenhouse gas emissions and requires very little maintenance.
