If the pressure rises when the boiler is off, it would be the pressure reducing valve or also called the fill valve.

If your boiler pressure is in the normal range when there is no heating demand (you aren't running hot water taps or you haven't turned the heating on), but you've noticed the pressure increases when you turn your heating or hot water on, don't worry. This is normal.

Modern boilers have built-in pressure release valves. These generally trip at 30 psi and release excess steam to bring the pressure back to normal. It'll also kick off the power to your boiler.
Get A QuoteSometimes, after prolonged use, a domestic coil inside the boiler jacket can develop a pinhole in the tubing. If this happens, the boiler pressure is affected by pressure from the domestic coil. In this case, the domestic needs to shut off and replaced.
