Hi All. I have a Halstead Ace boiler which I understand from this forum can be a bit temperamental, which I am currently finding out for myself!
I have an ongoing problem which I cannot seem to get to the bottom of, so am looking for a little help from anybody who has had a similar issue.
The problem is that when we draw off hot water for an extended length of time, a few minutes after turning the tap off the boiler hisses from the auto air vent and then cuts out (there is also often a gurgling sound). I then have push the overheat button back in and reset the boiler before it will work again.
I also think the boiler is a bit louder than it used to be.
So far, I have replaced the AAV which has made no difference.
The diaphragm was also replaced about a year ago, but that was for an unconnected problem of no hot water.
A couple of further points is that it does not happen when the heating is on and if you turn the hot tap on for a few seconds and then off again, whilst it is hissing, the hissing will generally stop.
Lastly, the temperature of the hot water can vary quite a lot whilst having a shower.
Any thought as to the cause of this would be greatly appreciated.
Thanks
