What is a power flush and do I need one?

A power flush cleans your heating system by circulating chemicals at high velocity to remove magnetite sludge, rust, and debris. You likely need one if radiators have cold spots at the bottom, the system is noisy (kettling), or your boiler keeps cutting out.

Why are my radiators cold at the bottom?

Cold spots at the bottom indicate magnetite sludge buildup – a very common issue in St Albans's hard water area. A professional power flush and magnetic filter installation will resolve this and protect your system going forward.

Is underfloor heating worth the investment?

Underfloor heating provides even, comfortable warmth and works very efficiently with modern boilers and heat pumps. It is ideal for kitchens, bathrooms, and extensions. Running costs are typically 15-20% lower than traditional radiators.

What smart thermostats do you recommend?

We install Hive, Nest, Tado, and Honeywell systems. The best choice depends on your needs. We also specialise in weather compensation controls which optimise boiler output based on external temperature for maximum efficiency.
