The most common reason for condensing boiler breakdowns

If the high-limit temperature setting is too high, generally over 200 degrees Fahrenheit, the system pressure will reach an excess condition as well and start leaking. The high-limit temperature setting should be around 190 degrees and the standard hot water operating pressure around 20 psi.

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

Jan 19, 2015 · The water pressure in a hydronic boiler shouldn't be over 12- to 15-psi. It should have only enough pressure to raise the water a few feet above the top of the highest point in the piping system. A 12-psi setting will lift water 28' above the fill valve.

Is your boiler condensate pipe leaking? Here's what to do!

boiler heating water system as a whole. Condensing boilers require entering water temperature (EWT) in the 100˚F (55˚C) range to actually condense water out of the exiting flue gas. The onset of condensing is with an EWT of about 130˚F (54˚C), but maximum efficiency occurs at an EWT of 80˚F (27˚C) or lower.

Water Heater Condensation - Hot Water Heating Guide

When the temperature of the water inside the tank drops below 110 F. Once the water inside the tank is heated above 115 F condensation should stop. It takes up to 2 hours for the water to heat up to the temperature where the condensation stops. During the cold start-up of the brand-new unit.

What Your Boiler Pressure Should Be When It's Heated

Dec 30, 2019 · High pressure can result from the boiler temperature being set too high. Higher pressures generally cause automatic shutdowns. Modern boilers have built-in pressure release valves. These generally trip at 30 psi and release excess steam to bring the pressure back to normal. It'll also kick off the power to your boiler.
