Enjoy Your Pool for Longer

A heated swimming pool transforms the way you use it, extending the swimming season and making every swim more comfortable, whether it’s for exercise, relaxation or spending time with family and friends. The right heating system also helps you maintain a consistent water temperature while keeping running costs under control.

Whether you’re installing pool heating for the first time, upgrading an ageing system or looking for expert servicing and repairs, Harlequin Pools provides honest advice and professional installation across air source heat pumps, gas, oil and hybrid heating systems. We take the time to understand how you use your pool before recommending the solution that’s right for you.

Why heat your pool?

Extend Your Swimming Season

Enjoy your pool from early spring through to late autumn—or throughout the year with the right heating solution.

Greater Comfort

Maintain a consistent, comfortable water temperature so every swim is enjoyable, whatever the weather.

Lower Running Costs

Modern heating systems, particularly air source heat pumps, can provide highly efficient heating while reducing long-term energy costs.

Heating Tailored to You

From daily family swimming to occasional weekend use, we’ll recommend a heating system that matches how you use your pool.

New Pool Heating Systems

Nobody wants to brace themselves before getting into their own pool. Whether it’s an early morning swim, evening relaxation or weekends with family and friends, a heated pool is simply used more often.

If you’re installing pool heating for the first time, choosing the right system depends as much on how you use your pool as the technology itself. A heat pump may be ideal for regular everyday use, while gas, oil or hybrid systems can better suit pools that need rapid heating or year-round performance.

We’ll assess your requirements, calculate the correct heating demand and recommend the most suitable solution before completing the supply and installation—all managed by one experienced team.

Heating System Upgrades

Many pool owners replace their heating system because it has become unreliable or increasingly expensive to run. Modern heating technology offers significant improvements in both efficiency and performance, making an upgrade a worthwhile long-term investment.

Air source heat pumps have advanced considerably in recent years and are now our most frequently specified heating solution thanks to their excellent efficiency. However, they’re not the right answer for every pool. Some installations still benefit from gas or oil heating, while hybrid systems can combine the strengths of both technologies.

We’ll assess your existing heating system, understand how you use your pool and recommend the most effective upgrade for your needs.

Servicing & Repairs

Regular servicing helps maintain the efficiency, reliability and lifespan of your pool heating system. We service the heat pumps, gas and oil boilers we install and maintain, keeping detailed records and providing service reminders so maintenance is never overlooked.

If your heating system develops a fault, our engineers will diagnose the problem quickly and recommend the most appropriate solution. Whether it’s a straightforward repair or a more complex issue requiring specialist support, we’ll manage the process from start to finish and warrant all work carried out.

Our goal is simple: to restore your heating system quickly so you can get back to enjoying your pool with complete confidence.

Our 10 x 5m pool was put in 4 years ago by Harlequin. It was not an easy build given the clay ground but the team led by Mike overcame fairly major problems with excellent lasting results. The pool was carefully planned with several detailed visits in good time prior to the construction. There have been no significant issues since. Harlequin were quite content to only start the pool off each early summer and close it down in the autumn as I was keen to look after the general maintenance myself which takes an hour or two per week. They do however help out if needed at any time for incidental issues. We have been very pleased indeed with the function and quality of the pool. I can certainly recommend Harlequin if you are considering a new pool.

I have used Harlequin for at least 12 years. They are absolutely bullet proof, very reliable and efficient. They answer the phone very quickly and always tend to a problem within 2 days. Cannot recommend them more highly. Mike Wainwright

Matthew has looked after our pool at Hill Farm ever since we moved here in 2003. He is most efficient, cheerful and patient with a customer who knows nothing about the maintenance of PH levels, water clarity etc. He has become a good friend over the years.

Harlequin built our swimming pool over ten years ago and it is still in pristine condition! We could not recommend them, or their maintenance service, more highly.
