Central heating problem

[garycooper7]

I have just had a new boiler fitted to my 1 pipe system.
I have back filled with a hose pipe, blead the system etc.

The first night everything was ok, the following morning when my heating came on 1 radiator possibly the last one was cold.

I have tried bleeding the system and quite a lot of air has come out 1or 2 of the radiators again.still would not get warm.

I have back filled again it starts to get warm a little, i have to blead the system everyday.

does anyone have any ideas what i can do?
Many thanks

little more info on your system?

gravity, pumped?

sealed, open vented?

boiler make and model?

And what do you mean back filled?

And why did the boiler installer not deal with these aspects?

Its quite common for air to need bleeding from a sealed system over the first few days.

I have a baxi solo boiler, gravity fed pump and vented system.

The installer did everything and it was working ok

And backfill is when you put a hose pipe on to the drain cock near the boiler and fill from the bottom hopefully pushing the air through the radiators and up through the cold water suppy tank, and then bleed the radiators as normal to finish of
