I have a Glowworm flexcom 24 Kw condensing boiler which was fitted 2 years ago.The prevous boiler was too small 50,00 btu's which I was running 9 rads from.Even with the old bolier I was never able to have all the rads on at the same time.I have tried balancing them with no change.I joined another site which was supposed to supply good tradesmen but the experience was very expensive.They came out after 2and a half hours I was charged £140 for investgating the problem.Then the next time I was told the 2 way zone valve was fitted back to front & I needed a cylinder stat which I did know to be true for safety reasons and they said the cylinder was taking all the heat and that was the reason I couldnt heat all the rads.They said I also needed a 3 way zone valve and a room stat as the temp for the rads was controlled by TRV's only.Because of attitude ,dirty work and 3 leaks caused by them and a total of £340 and unreliability on thier part I decided to cut my losses.I have been told by another plumber who I know Is Gasafe reg'ed that because of my set up I cant have a 3 way valve fitted to this system and he says I should get a seperate zone valve for the water.I think I have a s plan and not a Y I can upload a pic of the piping If anyone would like to see it.Because I have noidea about this I need to know I am getting the correct advise.Any advise is greatly welcome
