Swimming Pool Heat Pump
Supply & Installation

The right pool heat pump, correctly sized for your pool — supplied, installed, and commissioned by a specialist who understands both the refrigerant side and the pool side.

F-Gas certified. 15+ years experience. Systems sized using proper heat loss calculations, not guesswork.

We supply and install swimming pool heat pumps for domestic and commercial pools across Hampshire and surrounding areas. Choosing the right unit involves more than picking the biggest model — it requires accurate heat loss calculations based on your pool volume, surface area, exposure, cover usage, and target temperature.

An undersized heat pump will run constantly without reaching your desired temperature. An oversized unit costs more upfront and offers no practical benefit. We calculate the correct capacity and recommend a unit that delivers consistent, efficient heating for your specific pool.

We supply units from leading manufacturers and can source specific brands on request. All units are professionally installed with correct pipework, electrical supply, and positioning for optimal airflow and noise management.

Every installation includes full commissioning, F-Gas compliance documentation, and a demonstration of the controls. We also offer annual maintenance contracts to keep your investment running efficiently season after season.

Many pool owners purchase heat pumps online based on pool volume alone, without accounting for wind exposure, ambient temperatures, cover usage, or whether the pool is indoor or outdoor. This leads to units that cannot heat the pool to a comfortable temperature in anything other than peak summer.

Self-installation or installation by a non-specialist often results in incorrect refrigerant pipework, inadequate electrical supply, poor positioning that restricts airflow to the evaporator, and missing condensate management. These issues reduce efficiency and cause premature failure.

Pool heat pumps installed without proper water flow integration — for example, bypasses that are too small or missing non-return valves — can cause flow-related shutdowns and overheating that damages the heat exchanger.

Buying the cheapest unit without considering long-term running costs and serviceability often leads to higher total ownership costs. Cheap units with poor COPs use significantly more electricity over their lifetime than quality units, and replacement parts may be difficult to source.

Pool heat pump sizing requires calculating the heat loss from the pool surface, which is determined by pool area, wind exposure, difference between water and air temperature, and whether a cover is used. Covered pools lose approximately 50–70% less heat than uncovered pools, which significantly affects the required unit capacity.

We supply on/off and inverter pool heat pumps. Inverter units modulate their output to match the current demand, running at lower speeds when the pool is near target temperature. This reduces noise and electricity consumption compared to on/off units that run at full capacity or not at all.

Refrigerant choice affects performance at different ambient temperatures. R32 units generally offer better low-temperature performance than R410A, which is relevant for extending the swimming season into cooler months. We advise on the best refrigerant type for your usage pattern.

For commercial pools — hotels, leisure centres, swim schools — we supply larger capacity units or cascade systems where multiple heat pumps work together. Commercial systems require three-phase electrical supply and more robust water flow integration with the pool plant room.

We position outdoor units to ensure adequate airflow across the evaporator while managing noise for you and your neighbours. Units need clear space around them and should not be positioned in corners or against walls that restrict air circulation.

Water connections are made with appropriate bypass valves, non-return valves, and isolation valves so the heat pump can be isolated for servicing without draining the pool circuit. All connections are made with chlorine-resistant materials.
