I do however realise that the party may...

    Worcester Bosch Greenstar 30 CDi - Pressure loss

    Hi all, Recently moved into a new house and noticed the Greenstar boiler has low pressure on the dial. Quick Google suggests using a key, valves, or fill loop to increase the pressure. Only problem being is I don't have either of those things. Any help would be appreciated. Cheers.
