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

Heating on – boiler pressure between 1.5 and 2 bar. Heating off – boiler pressure between 1 and 1.5 bar. To increase boiler pressure – top up with water. To reduce boiler pressure – bleed your radiators. Check your boiler pressure once a month. Always use a registered engineer for any boiler repairs.
