A boiler that doesn't have constant water pressure won't be able to work as efficiently as it could do. Low pressure can often be an indication that there's an issue with the system, which is why it's important to find the cause.
if it's a gas or oil boiler installed after 2005, it's likely to be a condensing boiler. If the flue is metal and you can't see any steam, your boiler is likely the non-condensing variety. The good news is condensing boilers are easy to fit and tend to be energy efficient. A-rated condensing boilers have at least 90% efficiency ratings.

Boilers. A gas/oil central heating boiler (heat generator) is like the engine of a car, this provides the heat that the facility needs to warm itself up. The size of the boiler is matched to the size of the facility. If the boiler is oversized, the fuel bills will be excessive.
Hi Can you please advise what is the minimum operating gas pressure on the boiler? 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.
Boilers generally have 2 or 3 pressuretrols: a manual-reset pressuretrol, which functions as a safety by setting the upper limit of steam pressure, the operating pressuretrol, which controls when the boiler fires to maintain pressure, and for boilers equipped with a modulating burner, a modulating pressuretrol which controls the amount of fire.
The Economizer shall be a light weight design for easy installation, cylindrical with counterflow heat transfer design manufactured and tested in accordance with the requirements of Section VIII, Division 1 of the ASME Boiler and Pressure Vessel Code, and is stamped to a minimum 250 PSIG design pressure.
Gas valves are rated at 1/2 psi and if higher pressures are encountered almost certainly diaphragm rupture will occur with a resulting fire or explosion. The 7 inch water column pressure (1/4 psi) is received by the gas valve and reduced by its regulator to a lower pressure that the manifold distributes to the gas orifices.
If the gas pressure into the meter isn't correct, the gas pressure out of the meter and into the boiler isn't going to enable the appliance to function correctly. With gas pressure checks complete, they'll want to look at the component that controls the flow of gas to the burner; the gas valve.

Insufficient water pressure. Gas Boiler Troubleshooting Ways for Three Main Breakages. When your boiler produces inadequate heat level you should check the pressure gauge. It indicates the water pressure. The heating problem may be caused by an insufficient water level or abrupt changes of the atmospheres inside the system.
