Hi, I am Christiane a customer who didn't know anything about central heating until 2 months ago.I got a replacement boiler Vaillaint Eco Plus 418, new 3 port valve, new pump system flushed with inhibitor and vented
I then started to have a whooshing noise and but crackle and pop which travelled through the whole system.However, radiators bleed, all boiling hot , but then all started again.
Cut a long story short, the system is now sealed with an expansion tank, a valve that allows surplus pressure to get out (also been replaced ) constant pressure is 1 to 1.5, so no leaks.However, still air
Boiler temperature now set to 60 degree ( rather than 72 as previously ) .Pump also in the right way ,arrow pointing towards the distributer valve.Runs lovely and quiet once on.
However , when the timer starts and the pump runs, there is an oh mighty gulp..gluck gluck to be heard in the pipe in the airing cupboard and in the radiator in the bedroom.Then it stops when the boiler starts so only lasts for about a minute or so.
At the end of the heating cycle, when the timer switches the boiler off, immediately the big gulp....gluck gluck appears followed by whooshing in the radiators until the over run finishes.
This is driving me and all plumbers absolutely bonkers.
Sealing the system has only made little difference...And again, all radiators are warm, no air trapped in any....sometimes changing the setting of one of the Thermostatic Valves in the bedrooms upstairs may trigger the gulp too......
I have now had 6 plumbers and all scratch their heads....meanwhile I am frightened to put the heating on which is pathetic..but it stresses me out so much.
Any help is much appreciated
.
P.S. notices yesterday that the pump switched itself off at 55 degree flow temperature and then back on when the temperature was reaching 57, did that twice whilst I was watching..is that right ?
Any ideas are welcome, I have photos too
Oh, it appears that the 3 port valve is not working properly as hot water appears to be on permanently, even when it s CH only.That will be replaced tomorrow hopefully.
Thank you so much
