A central heating system is a big investment and it’s important that you make sure that you get the most out of it. One of the biggest things you can do to help your system is power flush it regularly. This will make sure that all the waste products in your radiators are flushed out and replaced with fresh new water, meaning they’re working at their best!

Your system is noisy — If you can hear your boiler running or the pump, it may be time for a Powerflush. If you can hear the expansion vessel running, it’s likely that the system is clogged up with sediment and needs a Powerflush.

Your boiler keeps turning itself off — If your boiler keeps turning itself off, the most common reason is that there’s dirty water in the system. Dirty pipes can cause an electrical short and cause it to turn itself off. This is dangerous because if you don’t know what’s going on with your central heating system, it could be deadly! If this happens to you, call a professional immediately so they can powerflush your entire heating system.

The system has become sluggish — It takes longer than usual to heat up- If your system takes longer than usual to heat up, it could be a sign that it needs a powerflush. You should get one if you notice any of these symptoms:

  • Your boiler is making strange noises or smells like something’s burning
  • You’re getting a lot of condensation on windows, walls and ceilings (more than normal)

You can see rusty water in the radiator- If you see rusty water in the radiator, it’s a sign that your heating system is sediment building up. Sediment is a residue of plant and animal matter that collects on the inside of pipes, radiators, and other parts of your central heating system.

Sediment can reduce the efficiency of your system as it clogs up vital parts like valves and filters which then cause problems with your house or business.

You should get Powerflush if:

  • You’ve seen rusty water in the radiator;
  • You have black deposits on all surfaces within 200mm (8 inches) around radiators;
  • There’s visible mould growing inside pipes or under taps where no water comes out at all

You should powerflush if any of these things happen

If you are in the market for a new central heating system and looking for ways to keep your old one running well, then powerflushing is an important part of the process.

Powerflushing can help ensure that your system continues working as efficiently as possible by removing any dirt or debris from inside its pipes and systems. This will help prevent clogs and other issues that could lead to more serious problems down the line.

It’s important to note that powerflush will only work if your system has been properly installed and maintained. If you have any doubts about what needs to be done, please contact an expert for Power Flushing London — LJB Heating and Plumbing!
