How they work

Heat pumps extract energy from the outside air and it is then transferred to the swimming pool water. Heat pumps are very efficient and operate in a similar way to refrigerators, absorbing heat and moisture from surrounding air and upgrading the energy to heat through a unique refrigerator circuit.

A fan is used to draw fresh air over evaporator coils, with heat from the airflow being captured as warm gas and then transferred to a compressor. The heat energy is intensified and upgraded by the compressor. The heat is then transferred to passing pool water via the titanium heat exchanger condenser. Heat pumps can harness energy from a broad range of air temperatures, specifically -15°C - 40°C but will perform best where the ambient air temperature is above 10°C.

The two ranges of heat pumps use Rotary or SCROLL compressors, which are reliable, efficient and quieter than conventional compressors. The fan of the heat pump creates a quiet sound.
A swimming pool heat pump produces no carbon emissions, with condensation being the only output from the system. The heat pump can be placed on a suitable base to accommodate any condensation produced.  
The heat pump design incorporates epoxy coated, galvanised steel cabinets and a titanium heat exchanger which creates a weather proof and long lasting machine.

An electronic control makes it easy to control the swimming pool temperature to suit the season or personal preference. Furthermore, it is simple to drain the heat pump when winterising or carrying out maintenance on the pool.

In extreme weather conditions over the winter period, the manufacture recommends moving the heat pump to a sheltered location.

The Basics

Swimming pool heat pumps can be installed by Enviko. We are one of the UK’s leading renewable energy companies and can install these for your swimming pool. Read more on how they work.

Heat from the air outside
The air outside is around 11-13°C and is heated by the sun to a constant temperature and so this is easily harnessed. These pumps absorb heat from the air outside using a refrigeration gas and this air the then circulated by use of a fan.


The heated gas is then compressed to strengthen the heat. The heated gas is then sent to a heat exchanger where it heats the swimming pool water. The refrigeration gas therefore cools and is sent back to be heated by the outside air again. basics of heat pumps used with pools in the UK

More energy efficient
This system is therefore energy efficient and works by simply taking heat from the surroundings and using it to heat water and so is perfect for swimming pools. At Enviko we can install a range of heat pumps and choose the best one for you. We have extensive experience and a large portfolio of many types of renewable energy installations.

Offering cheaper heating for pools
These are a cheap way of heating your house too, where the heat exchange contains air instead of swimming pool water and can if installed under the house provide under floor heating. This is easier in new builds but a heat pump can easily be installed in existing properties too. The exchange can also be switched to cool your house during the summer when it gets hot.

Installed and fitted Nationwide
We can also install ground source heat pumps to heat your home, these produce more heat than the swimming pool heat pumps although they cost more they can be a very effective way of providing heat.

They would provide enough to heat up hot water for central heating and can save you up to 50% on your bills by preheating.

These consist of pipe loops that go into the ground, the earth maintains a warm temperature due to heat from the sun and the centre and so water pumped down into the ground gains thermal energy.



Solar Panels

Solar panels supplied and installed by Enviko LtdThe standard solar panel is a photovoltaic panel that consists of several solar cells capable of collecting thermal energy released by the sun. These solar panels are connected together to create a larger system that is capable of converting significant amounts of solar energy to electrical energy. Due to factors such as rain, dust and seasonal changes a large amount of solar panels are used in a simple installation. This ensures that the required amount of light is captured and stored for later use when no thermal energy is available. There are several different types of thermal energy storage as well.
