High Pressure Boilers: Meaning, Types, Characteristics

The feed water from the hot well is pumped by the feed pump through the economiser and preheated water is supplied to the boiler drum. The water is heated up by the hot gases flowing in the upward direction, which are later exhausted through the chimney high in the atmosphere to reduce air pollution.

Basics of hot water heating boilers - Specifying Engineer

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. A 15-psi setting will lift the water to 34'.

Boiler Pressure Problem #1 Best HVAC Troubleshooting Tips

Dec 30, 2019 · Pressure changes of a few psi one way or the other can be brought about by atmospheric conditions. Most boilers are safe up to around 30 psi, at which point seals can begin to fail. Modern boilers aren't nearly as dangerous as early steam engines, but you can still damage them and require costly repairs. Provided your boiler stays in the 12-30 psi range, you're in no real danger.
