What is the safe pressure for a hot-water-heating system? The highest pressure the boiler should ever see is stamped on the boiler tag - Usually 30- or 50-psi. so the return temperature should normally be hotter than 140 F to prevent the boiler from rusting out and the chimney from failure. With a condensing boiler, you want the return

Steam, Boiler, and Blowdown Pressure are the same. Combustion Efficiency is the % of fuel energy that is directly added to the feedwater and not otherwise lost or used. Blowdown Rate is the % of incoming feedwater mass flow rate that leaves the boiler as a saturated liquid at boiler pressure.

Pressure and Temperature gauge on hot water or hydronic heating boilers: this gauge displays the heating boiler internal pressure and temperature. 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.

What is the correct temp setting for a hot water boiler

It can vary from 70 degrees (room temperature) up to 180F if you need it. The boiler is maintained at a different scale, the 180 to 140 range because you have to. Oh well. But the radiator will "sip" this water and return and equal amount back to the boiler. The boiler water not sent out keeps the boiler warm.

Boiler Temperature - an overview | ScienceDirect Topics

The boiler pressure is 12.5 MPa and temperature is 510°C. The condenser pressure is 50.8 mmHg and temperature is 38.4°C. The regenerator pressure is 132 kPa. Habib et al. (1995) indicated that for maximum efficiency of a single reheat cycle, the reheat pressure should be approximately 19% of the boiler pressure.
