High Pressure Boilers: Features and Advantages ~ ME Mechanical

Oct 27, 2016· A boiler is called a high-pressure boiler when it operates with a steam pressure above 80 bars. The high-pressure boilers are widely used for power generation in thermal power plants. In a high-pressure boiler, if the feed-water pressure increases, the saturation temperature of water rises and the latent heat of vaporization decreases.

Why Your Boiler is Losing Pressure | DHS Heating Bristol

A boiler should normally have a water pressure of between 1-1.5 bar. If the pressure drops much below 1 bar you won't get any hot water. If this is the case, the first step is to repressurise the system by adding more water back in, which is usually done with a key, button or switch depending on the type of boiler.

Repressurise your System - Boiler

Repressurise your System. Every pressurised system, regardless of the type of boiler (combination boiler, combi boiler or standard system), will incorporate a pressure gauge which you can read. This pressure gauge is the device with which the system water pressure in your boiler and radiators is monitored.

My hot water boiler keeps increasing pressure when it runs.

Nov 17, 2008· My hotwater boiler keeps increasing pressure when it runs. Normal pressure is 12psi but it has risen to as high as 40psi though the max pressure is indicated as 30psi on the gauge. I rcently replaced the flow control value which I set to the normal 12psi prior to use of the heater. The house is dual zoned and the problem occurs in bith zones.

Why do I have no pressure reading on the psi gauge on my

Nov 02, 2011· Why do I have no pressure reading on the psi gauge on my boiler. Turn the boiler off and then turn on the make up water bypass if you have one and pressurize the boiler to 12 psi and then turn the boiler on and bleed the air if the pressure drops below 10 then repressurize with the makeup water to 12-15 and repeat till the pressure holds and the there is no more air in the system.
