Amazingly, he quoted and installed a new better pump on the same day as my request, all for a reasonable price. Matt was courteous, efficient and very knowledgeable. Highly recommended and I can see why he consistently gets 5* reviews

Why Choose a Heat Pump for Your Swimming Pool?

Swimming pool heat pumps work by extracting heat from the surrounding air and transferring it into your pool water.

Rather than generating all of their heat directly from electricity, they make use of energy already available in the outside air, providing an efficient way to heat a swimming pool and maintain a consistent water temperature.

Benefits can include:

More energy-efficient pool heating
Lower running costs compared with many traditional heating methods
A more consistent and comfortable pool temperature
An extended swimming season
Suitable options for both new and existing swimming pools
Modern inverter heat pumps offering quieter and more efficient operation
Reduced reliance on gas or oil-fired pool heating

For many pool owners, replacing an ageing heating system with a modern heat pump can be one of the most worthwhile equipment upgrades they make.

If your existing pool equipment is also becoming unreliable or dated, we can provide a wider range of swimming pool repairs and refurbishment alongside your heating upgrade.

Choosing the Right Swimming Pool Heat Pump

Correct sizing is essential.

A heat pump that is too small may struggle to reach or maintain the required water temperature, while unnecessarily oversizing the system can increase the initial cost.

At Unicorn Pools & Hot Tubs, we consider the complete pool rather than simply recommending a unit based on one measurement.

Factors we may consider include:

Pool dimensions and water volume
Indoor or outdoor location
Pool surface area
Desired water temperature
Months of the year you intend to use the pool
Existing filtration and circulation equipment
Whether a pool cover is used
Location and exposure of the pool
Existing heating equipment
Available electrical supply

We can then recommend a suitable solution for your particular installation.

Regular swimming pool cleaning and maintenance can also help ensure that pumps, filters, circulation systems and other pool equipment continue to operate effectively alongside your heating system.

Replacing an Existing Pool Heater

If your current swimming pool heater is becoming unreliable, expensive to run or is simply reaching the end of its useful life, we can assess the existing system and advise on suitable replacement options.

A modern heat pump can often be incorporated into an existing swimming pool filtration and circulation system, making it possible to upgrade your pool heating without replacing the rest of your pool equipment unnecessarily.

We can assess the existing pipework, circulation, electrical requirements and equipment layout before recommending the best approach.

If your pool requires more extensive work, we also provide pool repairs and refurbishment including equipment upgrades and fault diagnosis.

Upgrading an Older Swimming Pool Heat Pump

Heat pump technology has developed significantly.

If you already have an older pool heat pump, replacing it with a modern inverter model may offer improved temperature control, quieter operation and better energy efficiency.

We can inspect your current installation and advise whether repair or replacement represents the most sensible option.

Our aim is always to recommend the solution that is right for your pool rather than replacing equipment unnecessarily.

Get More From Your Swimming Pool

British weather doesn't always cooperate with swimming pool ownership.

A correctly specified heat pump can help bring your pool up to a comfortable temperature earlier in the season and maintain that temperature as outside conditions change.

Combined with a suitable pool cover, efficient circulation and sensible temperature settings, your heating system can help you enjoy your swimming pool for considerably more of the year.

Keeping the water correctly balanced is also an important part of protecting your pool and its equipment. Unicorn provides swimming pool chemical supply and local delivery throughout our local service area.

Swimming Pool Heat Pump FAQs

How does a swimming pool heat pump work?

A swimming pool heat pump extracts heat energy from the surrounding air and transfers that heat into the swimming pool water as it passes through the system. This allows the heat pump to provide an efficient method of maintaining the required pool temperature.

What size heat pump do I need for my swimming pool?

The correct size depends on several factors including the volume and surface area of the pool, whether it is indoors or outdoors, the required water temperature, the months during which you intend to use the pool and the amount of heat the pool is likely to lose. We can assess your pool and recommend an appropriately sized system.

Can a heat pump be fitted to an existing swimming pool?

In many cases, yes. Swimming pool heat pumps can often be integrated into an existing filtration and circulation system. We can inspect your current equipment and advise on the most suitable installation.

Can you replace my existing swimming pool heater with a heat pump?

Yes. If you currently use an older heat pump, electric heater or another type of pool heating system, we can assess the existing installation and recommend suitable replacement options.

Are swimming pool heat pumps expensive to run?

Running costs vary according to the size of the pool, desired temperature, heat pump efficiency, outside temperature, how frequently the pool is used and how effectively heat loss is controlled. Modern swimming pool heat pumps are designed to provide an energy-efficient alternative to many traditional methods of pool heating.

Will using a pool cover reduce heating costs?

A suitable pool cover can significantly reduce heat loss from the surface of the water. Reducing heat loss means your heating system has less work to do to maintain the required pool temperature.

Can a heat pump extend my swimming season?

Yes. One of the main reasons pool owners install heat pumps is to maintain a comfortable water temperature beyond the warmest weeks of summer, allowing the pool to be enjoyed for a longer period of the year.

You can find answers to more common questions about pool heating, maintenance, repairs and running costs in our Swimming Pool FAQs.
