Heating Boiler Gauge Replacement Procedure

Heating boiler gauge replacement: this article describes the steps in replacing a pressure or temperature gauge on a hot water (hydronic) boiler or on a steam boiler. We give two different approaches to boiler gauge replacement, a wet process that is done without draining the boiler and a dry gauge replacement process that requires draining water out of the heating equipment.

Steam Heating System Operating Temperature

However a residential steam boiler pressure is so modest (0.2 psi to 0.5 psi) that the temperature increase above 212 °F will be no more than about 220 °F. A commercial boiler system heating a high-rise building may be operating at much higher pressures, perhaps 20 to 40 psi in order to be able to force steam to 20 or 40 floors of building
