One of the most common boiler faults is low boiler pressure. It is normal for the central heating system to lose pressure over a period of time. If you have bled your radiators recently, pressure could be lost due to that. Or it may be that there is a leak somewhere in your heating system. Sometimes leaks can be so small that they’re unnoticeable. It is recommended that you check your boiler pressure at least once a month to help reduce the chances of unexpected boiler breakdowns.
Your central heating boiler must have an operating pressure between 1 bar and 2 bar. Being at this pressure keeps the central heating boiler and central heating system free from air. If the pressure drops below the normal boiler pressure level, a safety switch is activated that cuts the boiler off - this is done to prevent damage to the central heating system and boiler. It also prevents both the central heating system and boiler from running dry (with no water circulating).
If your boiler has low pressure, you can top up your system and have your boiler working within a few minutes by following the steps below:
We’ve included some helpful links on topping up the pressure for some of the most common boiler brands. If your boiler is not listed, enter your boiler make with the phrase “top up boiler pressure.” For example: “Baxi boiler how to top up pressure.”
