Hi, any help appreciated.
In Nov 2015 we had 8 new rads put in and piping replaced to rads, and buried in walls. 3 old rads were kept in kitchen and utility room).
The water then never got round the system properly (50% ish of rads worked at a time, including the old rads consistently. Which new rads did or didn't work changed depending on the day).
At the same time, the plumber who fitted them found it almost impossible to balance them when refilling the system, which is a tank system, not combi...with a 4 year old Worcester Bosch green star ri boiler.
We just lived with the problem of some not working, as I'd already paid him and couldn't get him back (foolish in hindsight, I realise).
One year on, the boiler started cutting out intermittently. I got another plumber in who we paid to unblock a pipe that was very blocked, and he replaced the pump. We then suddenly had ALL rads working for the first time ever, which suggests (?) the very blocked pipe that fed the pump was the problem causing only a few rads to work previously. Then two weeks later the problem of the boiler cutting out intermittently recurred. So the plumber powerflushed the system, and made it a closed vented system, also adding an expansion valve (which together solved the problem of balancing the system when it needed to be refilled...as he was also experiencing this problem when he first tried to refill it).
A week later, and the boiler is cutting out again. I bled all the rads, and noticed one upstairs has no water in it at all (and bleeding them has made no difference...other than the boiler now won't come on at all).
Does anyone have any suggestions of what it might be? The second plumber is now suggesting it's the return pipe. But if this was the case, wouldn't the issue of the boiler cutting out have happened long before now? There were no problems with the boiler cutting out til 3 weeks ago (prior to any work at all being done by the second plumber). Any help appreciated, as we're thousands down since having the rad 'upgrade', and now without any heating whatsoever.
Thanks in advance.
