We recently have had installed a glowworm Xtrafast 120 combi boiler, and it has been working fine for some weeks, heating the two connected rads, this weekend the remaining 6 radiators have been installed (the pipes were already installed and filled), However the water pressure for the CH keeps dropping to 0bar (repeatedly) over a period of about 5 hours, All the rads have been bled and the pipe work connecting the rads is free from leaks and drips, Could some one offer an explanation, or will this keep happening until the gases have escaped from the water? It is very enoying and Cold in the mornings when the boiler has turned off because of no pressure! Any answers or suggestions would be v. much appreciated! Thanks STAPLE

As I understand it, if you have lost pressure on a combi it is more than likely due to a leak, but in your case if you have been bleeding the radiators then that amounts to the same thing. What you need to do is re-establish the pressure by use of the 'filling loop'. If your not familiar with this, do a search on this forum there is plenty of information on how to do it and the pitfalls.
