At Warmpools, we specialise in swimming pool heating solutions across London, the Home Counties, and the South East of England. Our team of expert swimming pool heating engineers recently completed a swimming pool boiler installation in Rickmansworth WD3, replacing an outdated and faulty Pentair pool heater with a high-efficiency heating system that ensures long-term reliability and superior performance.

The homeowner in Rickmansworth was struggling with a Pentair pool heater that had become unreliable and costly to maintain. One of the key issues with this type of heater is the lack of UK support, making repairs and spare parts difficult to source. Given the increasing maintenance costs and inefficiency of the old unit, the client opted for a complete swimming pool heating conversion.

To provide a durable and energy-efficient solution, our swimming pool heating engineers installed a Baxi system boiler, which comes with a 10-year warranty for complete peace of mind. This was paired with a Bowman heat exchanger and a Certikin pool thermostat to ensure precise temperature control and maximum heating efficiency.

• Baxi System Boiler (10-year warranty) – A trusted and efficient heating solution.
• Bowman Heat Exchanger – Ensures optimal heat transfer for fast, effective pool heating.
• Certikin Pool Thermostat – Provides accurate temperature regulation for comfort and energy efficiency.
• Professional Flue Installation – Carefully designed to integrate seamlessly with the existing roof, requiring a high level of expertise and precision.

One of the standout elements of this swimming pool boiler replacement was the flue installation. Given the structure of the existing roof, installing a new flue required specialist skills to ensure both functionality and aesthetics. Our gas-safe registered engineers carried out a professional and tidy installation, perfectly matching the original roofing design while maintaining compliance with building r

egulations.

By replacing the faulty Pentair pool heater with a bespoke swimming pool boiler and heating design, our client now benefits from:

✅ A more energy-efficient heating system
✅ Lower maintenance costs and UK-supported parts
✅ Reliable temperature control for year-round swimming comfort
✅ A seamless and professional installation by experienced engineers
