Hello, I wonder if somebody could help please. We have just moved into a house with a Potterton Lynx Electronic Combi Boiler & there are no instructions for water pressure. I can't find anything on the internet searces I've done either so I'm presuming it's a really old boiler! We've bled all our rads & refilled the system using the loop but we're not sure what the pressure gauge should say. I know that the standard is between 1 & 1.5 so we've done it to 1 as we don't want to over fill it. Please does anyone know the correct pressure for this boiler? Thank you very much.
