Understanding boiler specs - British Gas

Gas pressure 'Minimum inlet pressure' describes the lowest pressure required for gas entering the boiler in order for your boiler to operate safely and efficiently. It’s the most common specification you’ll see and it’s typically . .

2015/10/02 · I have been told by one of gas safe engineer that if the pressure is below 16.5mb for combination or system boiler, he cannot issue gas safety certificate. On the other hand I checked some certificates issued by another gas safe engineer for properties where the gas pressure on boiler is ranging 10 -11mb and issued passed certificate.

How often should I need to top up the pressure in the heating

Boiler pressure is one of the most common faults associated with the heating system, however there is an easy fix. When the heating system is cool, the pressure should be between 1 and 1.5 bar on the pressure gauge. Watch our

What to do if your boiler pressure is too low | Viessmann

If your pressure gauge is marked with a green zone and the needle has fallen below it, this is a sign that the gas boiler pressure is too low and action should be taken. If you have radiators that fail to heat up as they should, this may also be a sign that there is an issue with your boiler pressure and can be confirmed by checking the gauge.
