What Your Boiler Pressure Should Be When It's Heated - Eyman …

2019/12/30 · Pressure Change Range. Pressure will change when the unit fires up the heat. In most cases, it should rise to about 20 psi while its heating element operates. That's optimal at normal temperatures. Pressure changes of a few psi one way or the other can be brought about by atmospheric conditions. Most boilers are safe up to around 30 psi, at

What is the safe pressure for a hot-water-heating system?

2015/1/19 · 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).
