Placed a posting here a few weeks ago but got no response, I'll try one more
time before I spend a fortune on repairs. The problem is intermitant, it
is that 4-5 times a day the hot water suddenly dies and takes up to a few
minutes to come back on gain. 90% of the time its the tap downtairs, almost
directly below the boiler by about 4 meters. The problem rarely occurs in
the upstairs tap which is about 1/2 meter below the boiler and 3 meters
away from it. If I am downstairs and the hot water stops then I have to
leave that tap running, rush upstairs, turn the upstairs hot water tap on
for a 1 quarter of a second. When I do that I hear the boiler fire up and
the hot water suplly downstairs is then ok. The problem then occurs again
hours or a day later.
The engineer that installed the boiler 2.5 years ago is reluctant to take
the job on as its intermitant. Baxi will charge £239 to come out, diagnose
the problem and fix it.
So much for modern economic boilers....
