Boiler services London

If your boiler pressure keeps dropping, you’re losing water from your central heating system, water is leaking from ether your pressure relief valve outside, or from the central heating pipework or radiators. Check to see if you have a leak on any pipework or radiators, if not then the issue is most probably down to your expansion vessel needing repressurizing and your pressure relief valve replacing to resolve the issue.

Boiler noises can be scary, but it’s a common issue in London due to limescale build-up within the main heat exchanger and overheating occuring (ketteling).  This can be resolved by installing a scale reducer at the boiler or fitting a whole house water softener to have the benefit of soft water throughout your home.

Central heating systems can be complicated but firstly you want to determine if it’s just 1 radiator or more, if it’s just 1 then try opening the radiator valves all the way, one radiator valve may have a lockshield that needs removing before you can adjust the valve. If this doesn’t work, try turning off all other radiators 1 by 1 while until the radiator gets hot. If this doesn’t work it could be a faulty valve, blockage, pipe size issue, etc.. you need to remove the radiator to further investigate.

If you have no heating or hot water, firstly make sure the boiler is turned on and the thermostat temperature is set correctly, and check if the boiler has any pressure if the pressure is low try topping it up using the filling loop, but make sure your confident in doing so, but unfortunately there are many possible reasons why your boiler isn’t working and it will need to be looked into by a gas safe engineer.
