I have refurbished my house in Sept 07 and I removed all the old radiators and the old boiler. The builder used some of the old piping. I have installed new Heatline C28 boiler and new radiators. The builder installed it. He said he paid Corgi certified people to do the central heating. I wan not there. Now, I have two problems:
1. Some of the radiators are not heating and some are heating properly. The ones which are not heating take a long time to become warm and they normally become warn at the top and cold are the bottom. This is very strange to me, when there is an airlock, radiators normally warm up from the bottom and cold at the top. My case is opposite. I have seven radiators in the house and I thought may be the boiler is too small for the house, Could this be the case? If I close some of the radiators, the remaining ones become warm but even then they do not become enough hot.
2. Shower: I have a new Thermostatic mixer shower and it was working fine until two weeks ago. The problem is when you start taking shower, the water is hot for a minute and the next minute, it becomes cold, and then again hot for one minute and then cold again and so on. Before this problem started the water was hot from start to finish. What is causing this problem, is it the Thermostatic mixer or the boiler?
