What is a power flush and do I need one?

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

Why are some of my radiators cold at the bottom?

Cold spots at the bottom usually indicate sludge buildup. This can often be resolved with a power flush. Cold spots at the top usually just need bleeding to release trapped air.

Is underfloor heating worth it?

Underfloor heating provides even, comfortable warmth and works efficiently with modern boilers and heat pumps. It's ideal for bathrooms, kitchens, 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 - Hive and Nest are user-friendly, while Tado offers advanced features like geofencing and room-by-room control.
