Loss of pressure from Boiler?

[Chris1012]

Last week I released air for a loft radiator as it was not heating up. I then re-pressurised the boiler to the high end of 1.
The unvented boiler has been setup in a way that it provides central heating to all rads and hot water to just one tap whilst also heating up the water in the an unvented hot water cylinder.

A couple of days after I had re-pressurised the boiler, I came home from work one evening to a cold house.
Upon checking the boiler, the pressure needle was on 0 and there as an E1 error.
I re-pressurised the boiler again to under 2 and all was ok for another two days and again the pressure dropped.

I have just checked the unvented cylinder and it is damp all under it and where the external Flow outlet is from the cylinder into a pipe, it is more or less continuously dripping.

I have left a message for the plumber as he was unavailable.
How concerned should I be, is it a quick fix and can I still continue to re-pressurise the boiler as the needle has reached the low 1's and will soon be on E1 again...

Hello Chris, welcome along.
If I was you I would get someone out tomorrow to get things sorted. It doesnt look that great and needs doing. Call a qualified engineer.

You are looking for someone with g3 unvented qualifications. You can look on gas safe register and see who has it on their list of appliances they can work on.
