Industrial 4t Gas Condensing Boiler

Condensing boiler - Wikipedia. Condensing boilers are water heaters fueled by gas or oil. They achieve high efficiency (typically greater than 90% on the higher heating value) by condensing water vapour in the exhaust gases and so recovering its latent heat of vaporisation, which would otherwise have been wasted.This condensed vapour leaves the system in liquid form, via a drain.

How to Set Hot Water or Steam Heating System

Typical pressure for a residential boiler serving a two story home would show 12 psi cold, and less than 30 psi hot. Over 30 psi boiler pressure will cause the pressure relief valve to open. Typical operating temperature settings on a boiler call for a Low temperature (boiler cut-in) between 120 and 160 °F.

The Temperature in Your Boiler and the Dangers of

Once a boiler starts to go over 212°F, you can face serious problems. Watch out for overheating. If you notice that your boiler's temperature is going higher than the above settings, you have a major problem. If a boiler has reached 220°F, a sudden drop in pressure could cause the tank to burst. Overheating also is the main cause of leaking.
