Hi all,
I am after some advice.
I will try not to bore you with too much with the story behind this.
I had a conventional central heating system with boiler under the stairs, cylinder in airing cupboard and tanks in attic. I had a combi system installed a Worcester Bosch 30i by a local Worcester Bosch approved fitter.
This was installed in the airing cupboard after the removal of the cylinder.
I had an issue over Christmas where it was faulting on hotwater supply. I called out Worcester and they had to replace the heat exchanger. as it was blocker up which they said should never happen and that my system must be dirty. The system was never power flushed by the installer for what ever reason.
Ever since i can remember with this system it has been hard to get a comfortable temperature as it is always either baking hot or not warm enough. I have notice that the down stairs radiators bar 1 are hot at the top but cold at the bottom.
After speaking to a plumber i decided to do a flush on the system and run a cleaner through it.
I attempted to drain down the system last night and the 3 radiators that i have had issues with wont drain down whereas all the other do. When i have drained down the system in the past for maintenance/cleaning (before it was a combi system) i never had any issues with drain down.
The old boiler under the stairs had a supply and return water pipe and the gas supply pipe. When the boiler was removed from under the stairs the plumber looped the supply and return water pipes in the cupboard. I asked him if he could do this under the floor boards upstairs so that the cupboard would not have a pipe in it and also i could then remove the pipe boxing in the kitchen which was causing me an issue. I did offer to get the flooring up for him and everything but he didn't seem very enthusiastic about it so i suggested to him that i would do it myself at some point. He told me that i didn't have to put a loop in it just cap the end,which i did. but thinking about it now was that really the right thing to do wouldn't this just cause an air trap?
