I have had this Ravenheat 820/20 boiler for now 8yrs from the previous house owner.
During this time I have replaced the Divert valve for the second time just 2 months ago.
The first valve the diaphram was torn and couldn't find replacement back in 1999 so paide £180 for a new divert valve,
This valve started to leak from the front so had to replace it again after 6yrs.
I was searching for a supplier and came across BES and found they sold a replacement and appeared much cheaper so without searching around I ordered knowing I had paid a lot more for it 6yrs ago....I thought the price must have come down.
I had replaced the valve 2 months ago but it is today I noticed there is a problem with the hot water supply as today we have had a nice sunny day and hence the heating has not been running.
I went to have a shower this afternoon and there was very little hot water coming thru the mixer shower, had a look at the boiler flame and it was heating the water but this heat was going into the ground floor radiator instead of the hotwater circuit.
I was wondering what could be the reason for this behaviour with new valve from BES. Could it be the pin in the valve is sticking and hence the valve is remaining open half/half.
Any advice on how to check its operation besides seeing the valve going in and out with the opening of the hot water tap?
I must admit like everyone here thinks this boiler although is of very simple simple design the components are very poorly designed compared to the likes of Valiant's.
Any advice will be appreciated.
