Jun 08, 2021 · In most cases, high boiler water pressure is unlikely to be dangerous, as today's Combi boiler systems have a pressure relief valve which should trigger a shut down when the readings get too high. However, while it is an effective safety system, it is important to not rely on this pressure relief valve to resolve the problem.

Jan 07, 2021 · If your boiler has lost pressure, it is a good idea to do a visual check of all your radiators, towel rails, and any exposed pipework and joints to see if there are any signs of water. Even a small leak can impact your boiler pressure, so look closely. While looking, it is worth checking any exposed connections.

Naturally, boiler parts expand when heated. As such, when the hot water or heating is on, the pressure will increase slightly. However, the boiler should have pressure release options to stop the pressure from rising too high. Generally, a 0.3 bar pressure increase during hot water and heating is standard.

Kettling has the potential to be dangerous, as theoretically the high pressure could burst internal pipework and cause steam emission and electrical hazards. However, modern boilers should have built-in safeguards to detect the symptoms of overheating and shut down the boiler before it reaches that stage.

It's the fan in your boiler that helps to push dangerous gases out of the flue.

Jun 08, 2021 · If the pressure gauge reads above 2.5 bar, you have high boiler pressure. Obviously, neither situation is good, but in the case of low pressure, you'll have no hot water or heating, while in the case of high pressure, your system won't work as efficiently. It's good to know though that high boiler pressure is not dangerous in most cases.
Get priceThe division of megapascal pressure (MPa) determines whether a boiler is low and high pressure. Boilers that produce pressure above 80 MPa are considered to be high pressure.

Check the boiler's water inlet and outlet pipes well. If the pressure rises to over 3 bars, this is considered as abnormally high pressure and it could be because water is continuously entering the boiler. The safety valve will probably give you a warning by spontaneously expelling water to decrease the pressure (unless it is faulty).
