Boiler pressure

[dandingdong]

Hi

I had a new boiler fitted about a week ago. Everything was fine for the first night, but by the second night 2 radiators had gone cold. I bled the radiators and they both warmed up. In the morning the boiler had cut out as the pressure had dropped to 0.6 bar. I topped the boiler up to 1.5 bar but by morning the boiler had cut out at 0.6 bar again. I'm topping it up daily now. I've checked the radiator valves for leakes but can't find any and I'm guessing this kind of pressure drop would be quite a significant leak. Any ideas what it might be/what I could try?

Get the installer back.

You had it installed only a week ago. You shouln't have to try anything, get the installer back to sort it.
