What to do if your boiler pressure is too high | Viessmann

The pressure relief valve (PRV) releases water when the pressure in the system becomes too high. Sometimes, the PRV can have a leak or the valve may not close properly, this could gradually reduce your boiler's pressure. Alternatively, a filling loop (which is opened to allow water in when your boiler's pressure is too low) may have been

BASIC WATER TREATMENT OF STEAM BOILERS

A boiler is an appliance designed to heat water and produce energy. The heat is applied to water in an enclosed container before being distributed throughout the system. The major difference between a low-pressure and a high-pressure boiler is the amount of pressure per square inch and pounds per square inch gauge that the boiler produces.
