Why Your Boiler is Losing Pressure | DHS Heating Bristol

A boiler should normally have a water pressure of between 1-1.5 bar. If the pressure drops much below 1 bar you won't get any hot water. Repressurise your boiler. If this is the case, the first step is to repressurise the system by adding more water back in, which is usually done with a key, button or switch depending on the type of boiler.

How to Recharge an Expansion Tank on a Hot Water Boiler

Note: An expansion tank is not found in steam boiler systems, which create heat by circulating hot vapor rather than hot water through the pipes and radiators. Steam boilers are simpler systems that lack several components found in hot water boiler systems—such as the circulating pump, expansion tank, and regulators for water pressure and temperature.
