Everything you need to know about your boilers pressure Gauge.
It’s normal for your boiler pressure to rise as it heats on a demand from heating or hot water, and to fall back to the standing needle as it cools back down. Boiler pressure dials generally indicate low and high boiler pressure with green and red colour coded markers.
On a majority of boilers – Combination or System boilers – the pressure gauge is either on the front of your boiler or behind a control panel. Whereas Heat only boilers tend to have a pressure gauge in the airing cupboard next to your cylinder.
LOW BOILER PRESSURE
Majority of boilers do lose pressure slowly over several months of regular use therefore need very little attention. An annual service is usually, all that is required.
Boilers need to be topped up with water via the filling loop perhaps once or twice a year. However, a sudden pressure drop is a sign of a system leak or a flat expansion vessel. Drips of water around the base of the boiler are the most obvious signs of any leaks. Sometimes, the pipes may be at fault, so it’s useful to look for patches of damp along with all the pipework.
HIGH BOILER PRESSURE
High boiler pressure on the other hand, where the needle is in the red zone is typically due to overfilling or a passing filling loop which hasn’t properly shut off. Or again if the expansion vessel is flat, and needs a routine servicing re-charge of the vessel is vital as a flat vessel is also a sign of the boiler pressure needle rising into the red zone on the pressure gauge dial. A fault in the system could also cause the problem. If your boiler is shutting down or won’t switch on, you have a problem. Call a Gas Safe engineer. It is paramount early diagnosis and resolution is the best course of action.
If your boiler pressure is high, leaks can also develop. Keeping the correct boiler pressure is both safe efficient for hot water and warmth. If you at all concerned call a professional Gas Safe heating engineer to look at your boiler for you, you can book this online as a routine service with https://anygasservice.co.uk/ – Any Gas Service, or alternatively call 03333442216.
COMMON PROBLEMS WITH BOILER PRESSURE
When there’s no heating or hot water, it is usually because the heating system boiler pressure is wrong. Your radiators won’t warm up properly unless the boiler pressure is in the right zone.
Low boiler pressure isn’t dangerous but will cause your heating and hot water system to fail, and can also Burn out your boiler pump over a period of time. Sometimes, small leaks happen very slowly drip by drip over time until the pressure in the system is just too low to operate. Removing air from radiators also known as bleeding radiators, while good for your Radiators eventually, it can cause an immediate boiler pressure drop and require a system top-up. You can usually re-pressurize your boiler yourself from the filling loop, Once the pressure is back up and stays up with no apparent signs of leaking water, you can only then power the boiler back up.
High boiler pressure will cause the system to eventually shut down. It’s not usually dangerous as all pressurized boilers have a pressure relief valve (PRV). This boiler pressure relief valve lets water escape, down a small copper pipe that runs to the outside. However most systems shut down automatically when boiler pressure is too high.
Boiler pressures that keep rising to the red zone are best left to a Gas Safe Engineer to diagnose problems, and restore your hot water quickly.
