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

Boilers are built to quickly control these jumps in pressure via the pressure relief valve. This means that you can safely use your central heating and run hot water at the same time. Your boiler pressure should not increase by more than 1 bar above it's optimal working pressure when you turn the heating on.

The Difference Between Boilers And Water Heaters

Depending on how much you turn your hot water handle, the water heater will "send" hot water, which will mix with the cold water, to your sink or shower. This is done through the pressure in your pipes - as the sink or shower is turned on, cold water is put into the water heater, moving the warmed water into the pipes and to your faucet.
