Is it a problem if my boiler loses pressure?

A gas boiler needs a certain amount of stable pressure in the system to get the water around the maze of radiators and pipes in your home. In this article, we’re reviewing whether this is an issue that can cause you serious issues.

If your pressure falls too low, you may suddenly find that you have no heating. Fortunately, low pressure is fairly easy to identify and remedy, although there may be underlying problems that require professional attention.

Most modern boilers have a pressure gauge or a digital indicator for pressure, so consult your boiler’s manual to learn how to identify whether the pressure is within an acceptable range. More water can be added to the system through a filling loop that is connected to the water mains. The manual should outline the process, and there may also be instructions at the rear of the control panel. However, you should never remove this if it requires tools to do so, as only a qualified engineer should ever open a boiler.

Getting to the source of the problem may be harder, however. If you’ve recently been bleeding your radiators, it’s entirely normal for the pressure to drop due to the air that’s been released from the system. If not, check around the pipes and radiators for damp patches that may indicate a possible leak. The boiler can also leak, but never open it to check.

If you suspect a boiler or system leak, you can ask Xgas to dispatch a gas engineer to Wrexham or other locations in the area to safely inspect it and take corrective action if needed.
