HOTSPOTS

Hover over the hotspots to view the problems you may
experience with your home energy system.

Noisy radiators & pipes
Trapped air and dirt can cause annoying gurgling sounds in your radiators and pipes when your heating is running.
Radiator cold spots
When air and dirt build up in your radiators, this can result in cold spots, making it harder to heat up rooms in your home.
Higher energy bills
Air and dirt slow down the water flow, forcing your boiler to work harder and reducing its efficiency. The harder your boiler has to work, the higher your energy bills.
Repeated radiator bleeding
Noisy or radiators that don't heat up properly often require regular bleeding to remove trapped air that has collected around the system.
Boiler breakdowns
After dirt has travelled around your heating system, it returns into the boiler. Here, it can clog up expensive parts, leading to faults, breakdowns and costly repairs
