What to do if your boiler loses pressure - British Gas

Ideally, when the boiler is on, the pressure should be between 1,5 to 2 bars, and when its not working 1 to 1.5 bars. Usually, safe levels of the pressure are marked in green, and too low or too high-pressure is marked in red. We consider high boiler pressure when the arrow points in the red zone exceeding 2 bars.

Boiler Pressure Too High, Low, Keeps Rising, Dropping

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.

What is the safe pressure for a hot-water-heating system?

Jan 19, 2015 · The pressure the system is designed to operate at is usually 12- to 25-psi for a two-story house, and 18- to 25-psi for a three-story house. The operating high temperature should not be over 200 F., but 180 F. is the normal maximum design temperature.

What Should The Boiler Pressure Be When The Heating Is On?

Nov 07, 2019 · When the heating is turned on your boiler pressure should be between 1.5 and 2 bar. Most boilers will highlight this area on the pressure gauge in green to help you see if the needle is pointing to the correct amount of pressure. Some boilers will also have the critical zones below 1 and above 2 marked in red to help you identify any issues.

What Your Boiler Pressure Should Be When Its Heated

Dec 30, 2019 · To find the optimal pressures, consult the manual that came with your boiler. But if thats lost, most boilers are so similar the pressure differential between them is relatively minor. In any event, the usual cold pressure of a boiler should sit at about 12psi (pounds per square inch).
