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 can provide even warmth, but suitability and running costs depend on the property, insulation, floor construction, heat source and controls. We can discuss whether it suits your project rather than promise a fixed saving.

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.

Central Heating Solutions

A properly functioning central heating system is essential for comfortable living in London's climate. IQ Plumbing provides comprehensive heating services, from simple radiator repairs to complete system installations.

If your radiators have cold spots, your heating takes too long to warm up, or you're experiencing uneven temperatures throughout your home, our engineers can diagnose and resolve the issue quickly.

We assess the boiler, radiators, valves and controls before recommending work. Power flushing can help where sludge is affecting circulation, but cold radiators do not automatically mean the whole system needs a flush. We explain the findings and the appropriate repair or maintenance options.
