    Yet Another Boiler Losing Pressure Issue

    Looking for some help here - not my boiler, so consider me a proxy. I'm also by no means a heating engineer: I'm just looking for pointers, as the owner of this boiler is now caught firmly between "not us", "not us" and "not us" - nobody will take responsibility, and just calls into question...

    Ideal boiler had the F1 code, so topped pressure up but code persists.

    After researching as much as I can to sort this problem, I keep reading that if your Ideal boiler has an F1 code and the pressure is low, it needs topping up. If it has an F1 code but the pressure is fine, then this indicates a potential pressure sensor fault. What if it was low (completely...

    CP12s operating pressure / heat input??

    When doing a gas safety check / certificate you are asked to check heat input or operating pressure. I have been told that you can’t record the operating pressure on a boiler with a zero guvnor it has to be a gas rate and calculate heat input. Do you agree?
