The old boiler was replaced by a new, smaller energy efficient boiler. It was installed quickly as the installers had second job in afternoon. They switched it on and the radiators and water got hot downstairs. After they left, I noticed I could not close my back door as the outside pipe was in the way of the door closing. But much worse then this is that only the radiators downstairs are getting hot. I have called 3 times and never had a return call. I have been told by a plumber to bleed the radiators and then find a balance between all of them. I have tried but with minor success. This is not my job to do. The old boiler worked fine and we are already dreading the thought of winter. My child of under 16 and I live alone in home. We expected just a fully functioning boiler as we had before. It's a shame as boiler is good. If only the installers had spent 1 hour more and left the property knowing all was working fine.
