Complheat » What To Do If I Have A Low-Pressure Boiler

Most boilers today come with a built-in pressure gauge which makes a low-pressure boiler quite simple to identify. The pressure gauge is typically found on the front of your boiler and should be set around the 1 bar. The position is set when the boiler was initially installed and is sometimes shown by a red indicator needle. There are several reasons why you may have a low-pressure boiler. One of the most common causes is a leak somewhere in the combination boiler or the central heating system.
