The boiler man came and fitted the boiler no problem, but he didn't tell us that the pipes are going to be on show, on my old boiler the pipes were hidden inside the boiler, but he made good the wall for the condensate pipe, so happy with that, I was lead to believe that the boiler was sealed unit, by that I mean no pipes were on show, but this is not the case, if you look in the Worcester brochure it looks like there's no pipe work, and I was expecting that look, but what I got was something different, the workmanship is good and would have got a five star rating from me, but I had to make a box to cover the pipping, which is a shame because it alters the look of the kitchen, as for glow green they were great, very helpful and polite all the way through the process
