Local Heating Engineers

Restore the efficiency of your central heating system with a power flush. Although if you can’t see it, the efficiency of your central heating system might be reduced over time. A heating system can become clogged up with deposits and sludge, which gradually decreases its smooth running. If the radiators in your home aren’t heating your property as quickly as they should, you may book a power flushing of your heating system. Here at Belfast Contracts we provide a professional power flushing service as a one-off deep clean that saves time, money and stress whilst delivering exceptional results. Regular annual check and servicing of your central heating system could increase its efficiency by as much as 30% which also means cheaper fuel bills in the future.
At Belfast Contracts we are proud to deliver high quality services for our customers with their peace of mind in consideration.

When should I book a power flush?

If you are experiencing any of the issues below, a power flush is the perfect solution:

A noisy heating system, such as around the boiler or radiators

The radiators are cold but the pipes are hot

Cold spots at the bottom of your radiators

Heating is a slow or ineffective process

Inconsistent warmth from multiple radiators

Small leaks from one or more radiators

No water escapes or it’s dirty when you bleed a radiator

The boiler often shuts down or needs restarting


Our local heating engineers are available on call 7 days a week
