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.

What Are the Normal Hot and Cold Operating Pressures of Residential Hydronic (hot water) Heating Boilers? On a residential heating boiler the automatic water-feeder/pressure reducing valve that automatically provides makeup water to the heating boiler if pressure drops below 12 psi. So 12 psi is the typical "cold" pressure for residential boilers.
8 | Industrial boiler technology for beginners The use of boiler systems in practice Industrial hot water boiler systems for generating thermal heat are very similar to the household heating boilers in our cellars. The main difference is that industrial boilers are
In these hot water systems, once the radiator or baseboard convector is heated with the hot water, the cooled water is returned back to the boiler to be reheated, and the water circulation loop continues.
