Hello, I have had a bit of a nightmare on a WB boiler installation. Basically, it failed on Gas Safe inspection on 3 points. Installer came out to rectify months after and rectified the boiler regarding access points and flu. However, when we saw the flue, we were shocked. We had no idea it would protrude so much and looks very unsightly. It is a horizontal flue on a pitched roof. Basically don’t know what to do – we are not happy with the flue – but it meets requirements in terms of distance measurements. We are not happy with it though, visually it looks terrible. I was wondering, what are the option ref re-flueing. I believe a horizontal flue can be made vertical (so it would blend in a bit more and be aligned with chimney and not look so unsightly). I have no idea what this process involves. Property is flat in period conversion. Boiler was relocated to loft area from kitchen to make more space in kitchen. Installer said could de done and installed a year ago but it failed on GS inspection. Now rectified it looks so much worse from the outside. Really don’t know what to do and think only option is re-flueing and my own cost. Paid a lot of money for this already. Thank you!
