After last weeks exploits of no hot water unless the heating was on, was finally tracked down to the valve stuck at the back of the diverter valve so hot water was going straight out the boiler flow , instead of the valve shutting and the water coming out of the HW flow. This week I've fitted new valve ,all went well ,no leaks ,not even on the front slip fitting sealed with the "O" ring .Pressurised the Expansion vessel , filled up the system to 1.0 bar , run water through the system ,then bled the pump, everything looked all systems go but still something is stuck or malfunctioning . When hot water or CH is turned on gas burner fires up ,then after a few seconds ,the pump makes a struggling sound ,starts clunking and the gas valve shuts off , sounds like the water is not getting through to the water to water heat exchanger ,then the pump just stays on and won't go off , can reset gas shortly afterwards and light pilot again ,but the circle repeats itself . The water to water heat exchanger doesn't get the slightest bit warm ,but does have water in it if you drain it so must be getting through to it somehow .The diverter valve was "AS New" and came from a recently scrapped boiler and looks great and all valves look like they are working/opening fine ,but if the valve is at fault I can get money back (7 Day warranty) and get a brand new one instead. So quick help if you can so I can return if need be ,I would have bought a straight new one had not some suspicious character have handed my debit card into the shop I last used it. Card got cancelled about 5 mins before I phoned the bank to do so myself, just after I had phoned the shop to be told it wasn't there at all ,starnge the timing on that one hey? Got a new card yesterday but new pin hasn't arrived so don't have access to my own money till the pin gets here , so here goes folks :
1. Is the diverter valve not working properly still ?
2. Or is there some other reason the gas valve trips constantly (obviously a safety feature) but being caused by what.
I believe it was the "gasguru" who was spot on for me last week and sorted my problems ,so if your out there m8 or any other kind soul who can help please feel free to leave me some good advice .
Or there was an option 3.
Anybody got a spare stick of dynamite
