Jan 19, 2015 · Most residential hot water heating systems run at 5-psi more than the pressure required to raise the water from the fill valve to the highest point in the system. In my Cape Cod house, with the boiler on the floor of my garage, the pressure gauge reads between 12- and 15-psi (the dial is too small to read more accurately than that).Get Price
As with any hot water or heating appliance, a hot water boiler system requires a constant pressure flow to maintain the optimum temperature. Hot water boiler systems are equipped with a pressure gauge and an automatic pressure reducing valve that will add water to the system if the pressure drops.Get Price
Boiler controls help produce hot water or steam in a regulated, efficient, and safe manner. Combustion and operating controls regulate the rate of fuel use to meet the demand. The main operating control monitors hot water temperature or steam pressure and sends a signal to control the firing rate, the rate at which fuel and air enters the burner.Get Price
