Hi Alan, I had that issue last summer. Suspected both the heat exchanger and the hot water tank. So I disconnected the coolant hoses from the hot water tank and just connected them together (thereby just by-passing the HW tank).
Then I replaced the seals on the heat exchanger, which definitely needed replacing! That solved the problem. I'll try re-connecting the HW tank this week to see if problem returns. If it does, then HW is also the culprit.
