My Swim Spa Heat Pump Needs Replacing! Where Can I Buy a New One?

If your swim spa isn’t heating as it used to, or you’re waiting far longer than normal for the water to reach the perfect temperature, there’s a good chance the issue lies with the swim spa heat pump. It’s one of those components you don’t think about until it stops doing its job.

We speak to plenty of swim spa owners who come across these issues and unsure as to whether they need a repair, a replacement, or a whole new setup. In many cases, replacing the heat pump is the simplest and most effective solution.

How do you know it’s the heat pump?

A failing swim spa heat pump usually gives a few clues before it stops altogether.

You might notice your swim spa struggling to keep its temperature, especially overnight or during cooler weather. Heat-up time can creep longer and longer, or the system may run constantly without much improvement. For some owners, rising electricity costs are the first sign that something isn’t right.

If your heat pump has been working hard for several years, especially with year-round use, it may simply be reaching the end of life.

Common reasons a swim spa heat pump needs replacing

Age is the biggest factor. Older heat pumps are far less efficient than modern models and tend to work harder to achieve the same result.

Exposure to the elements also plays a part – heat pumps sit outside, dealing with damp air, temperature swings, and seasonal wear. Over time, internal components can deteriorate, leading to reduced performance or repeated faults.

In some cases, the technology has simply moved on. Newer swim spa heat pump models are quieter, more efficient, and better suited to UK conditions, making replacement a sensible upgrade rather than just a fix.

Is it worth replacing rather than repairing?

Often, yes. While minor issues can sometimes be repaired, repeated callouts or ongoing inefficiency usually points towards replacement being the better long-term option. A modern heat pump can reduce running costs and improve reliability, so you can enjoy it all year round.

For people using their swim spa regularly, whether for fitness, recovery, or gentle movement, consistent water temperature is essential.

Choosing the right replacement

Not every heat pump is suitable for a swim spa. Size, compatibility, airflow, and placement all matter, and choosing the wrong unit can lead to frustration rather than improvement.

The right swim spa heat pump depends on your spa’s volume, how often it’s used, and where it’s installed. This is where specialist advice is valuable, particularly if you want something that performs well in British weather.
