Low boiler pressure is one of the most common reasons people ring us in winter. Sometimes it's a two-minute fix you can do yourself. Sometimes it's a leak that will keep getting worse. Here's how to tell the difference.
Most combi and system boilers should read somewhere around 1 to 1.5 bar when the heating is cold, rising a little when it's running. Check your boiler manual for the exact figure. Below about 0.5 bar, many boilers will lock out and stop heating.
Most combi boilers have a filling loop: a short flexible hose or a built-in key with one or two small valves. With the heating off and cool:
If you're not sure where the filling loop is, or it looks different, stop and ring us. Don't force valves.
If you need to top up more than once every few weeks, something is wrong. Leaving it risks water damage and wear on the boiler.
Any work inside the boiler casing must be done by a Gas Safe registered engineer. If you ever smell gas, leave the property and ring the National Gas Emergency Service on 0800 111 999.
This is general guidance, not formal advice on your property. Rules change, so we check the current position at the free site visit and handle any applications as part of the job.
Usually around 1 to 1.5 bar when cold. Check your boiler manual for the exact figure.
Not usually dangerous, but the boiler may lock out and a leak can cause water damage. Find the cause rather than just topping up.
Rarely. Needing to top up more than every few weeks usually means a leak or faulty part.
No. Anything inside the boiler must be done by a Gas Safe registered engineer.
