If you already have a swimming pool and you're finding out how you can best heat it - or are in the market for a swimming pool and you know you'll want a heated swimming pool - look no further. Here are the options we have to hand:
Indoor Swimming Pool Heating

Why Indoor Pools Need Special Heating
Unlike outdoor pools that only get used during the warmer months, indoor pools are typically in use all year round. That means the heating system needs to be reliable, energy-efficient, and consistent. The goal isn’t just to heat the water — it’s also about managing humidity, air temperature, and energy usage inside the building.
Top Heating Options for Indoor Pools
1. Electric Resistance Heaters
These work like an immersion heater, using an electric element to heat the water directly.
- Great for smaller indoor pools or spas
- Heats water quickly
- Best for occasional use, as they can be costly to run over time
2. Air Source Heat Pumps (ASHP)
Air source heat pumps are an excellent all-round solution for indoor pools.
- Highly energy efficient (typically 3–5x more efficient than electric heaters)
- Consistent performance, especially in well-ventilated plant rooms or areas with access to outside air
- Can also be used to heat the surrounding air, helping control humidity
3. Heat Exchangers with Boilers or Heat Pumps
If the home already has a gas boiler, biomass system, or air source heat pump for central heating, a pool heat exchanger can tap into it.
- Great for new builds and renovations
- Very efficient — uses the home’s heating infrastructure
- Low-profile and ideal for indoor technical rooms or plant areas
Outdoor Swimming Pool Heating

Why Outdoor Pools Need Efficient Heating
In the UK, outdoor pools are typically used from late spring through early autumn — but with the right heating system, the swim season can stretch much longer. Whether it's a family pool or a garden spa setup, reliable heating makes a huge difference in comfort and usability.
The key is choosing a system that’s cost-effective, weather-resistant, and suited to how often the pool is used.
