When your boiler is making strange noises or your radiators have cold patches, your heating system may have a blockage that is stopping it from functioning properly. Before you panic that you need a replacement, try Greenstar’s power flushing solution to help get your current system working as good as new! 

How power flushing works

Power flushing is a fast and effective way to cure most circulation and noise problems with your heating system. Our experienced technicians calculate the most effective water pressure to blast away sludge and corrosion deposits that build up over time while ensuring no physical damage occurs to the system itself. Having restored optimal water flow, your system doesn’t have to work quite so hard, meaning you’ll be able to once again enjoy a quiet, efficient boiler and, as an added bonus, a reduction on your energy bills. 

The benefits of power flushing 

Incredibly, research shows that 80% of all central heating system issues are directly related to the build up of sludge, so before you replace your existing system, consider the benefits of trying a Greenstar power flush instead: 

•    More cost effective than replacing your system
•    Disperses heat more evenly throughout your home 
•    Less stress on your boiler – helping to prolong its life
•    Radiators and pipes get hot quickly, so you’ll feel the heat faster 
•    You’ll save money on your energy bills as your system will be more efficient
