Is your boiler losing pressure? What to do if you have low

What is boiler pressure? Modern boilers are often installed as part of a sealed heating system. Unlike open systems that need a feed and expansion header tank in the loft to regulate the water in the system, sealed systems contain a fixed amount of water and can be topped up manually by opening the valve.
