I have 7 radiators in the house and the cupboard with the pump and tank are on the landing, with a header tank in the loft. Downstairs I have 3 rads, 1 hall, 1 dining room and 1 living room.
Last week the radiators downstairs stopped getting hot. We did the usual and bled the system but it didnt make a difference so we called British gas under our celcia cover. The guy came and replaced the pump. He turned off all the upstairs rads "to force the water down" and lo and behold I had heat downstairs. Until he left. Then it went cold.
7am next morning the pump was screaming so we called BG again. The 2nd guy bled all the rads and again forced heat down and it worked. Until he left. Then it went cold.
This afternoon was number 3's turn. He was the first to go into the loft and confirmed the tank was ok. He then opened the Y valve (?) and replaced a small rubber ball on a brass plate which was fractionally enlarged. He put a magnet on the pipe that led downstairs and demonstrated that it stuck so "It must be blocked". He then went downstairs and attatched a pipe to the hall radiator and led it out the front door into the guttering (our door is a floor up, we have a garage underneath us with guuttering around it).
At this point I went to move my car and I noticed what was coming out of the pipe, pure clean water.
After much to ing and fro ing he turned on the heating again. Withing 10 minutes the pump was "screaming" and the dining room and living room radiators were tepid. He said that we had a blockage and the whole pipe needed cutting away where the magnet had stuck and the entire system power flushing. The cost £635.
I said I needed to speak to my husband and as he was going I touched the hall radiator.....it was burning hot. I enquired as to how if we had a blockage this radiator was hot but he rattled on about valves and left.
I spoke to my other half who spoke to a plumber friend. He told me to take another water sample from the hall rad because if we indeed had a block it would be murky. I have done that and its crystal clear.
So, now Im in a quandry. If celcia do it its going to cost me an arm and a leg but the guy said if they dont it may affect the terms of our cover. Im not sure I believe this guy at all.
Any input would be greatly appreciated!
