I have dual-zone gas boiler. The first zone is working just fine - the boiler lights up, heats and pumps the water up. The second zone, however, throws "tantrums". Two days in a row, I had no heat upstairs. I swapped the thermostats (digital) to see if that's where the problem was, but it made no difference. I figured, maybe it was the power head of the zone valve that was old and faulty, so I got a new one. The heat worked.... one day. The next, nothing. The following morning, I gave it a shot again and turned it on - it worked. Tonight, once again, nothing. Water is being sent up, but the furnace doesn't turn on to heat the water.
Anyone got a clue what the problem might be before I call for an expensive professional help?
