Our boiler heats water on demand, so no hot water tank, but it too started to fail.

I noticed the central heating water pressure dial kept dropping so I had to add more water by the fill link.

I reported it, but nothing was done (council cuts).

I rereported it and the engineer found that the rubber bladder was leaking. That dropped pressure to the point the system would shut down both central heating and hot water.

The bladder is up against the wall so it meant a total stripdown....
