Pressure Issues
I have two boilers that are fed from the same supply. The feed has an automatic fill and a back flow preventer. Now here’s the question; the pressure balance isn’t the same on both boiler. The boilers are approx 380,000 btu and a 60,000 btu. The smaller boiler is always at least 10 psi higher than the larger one.
I didn’t plumb the boilers but my first thought is that providing each boiler with its own separate fed would eliminate the pressure difference. By this I mean from the cold water supply two branches each with a automatic feed valve and back flow preventer to each boiler.
Am I seeing this right or am I missing something else?
TIA
