This is the third winter we've had this problem. Maybe longer.
The Utica 8175 boiler works fine, when it works. However, at the beginning of the season, when you flip the electric switch on, you don't know if it's going to work or not. When it isn't working, what happens is that the pump clicks on, but the gas valve part (I'm guessing) doesn't fire up, and you don't get that several minute long noise of the furnace working.
If it's all been working for weeks and you change a thermostat (we have 3 zones), if might make the boiler not do that last step of heating up the water to steam and moving it out. ie changing a temp on a t-stat could make the boiler stop heating up and circulating the heat thru the pipes.
I hope this makes sense. I had a heating guy out and he heard it working and I told him which noise doesn't come on when it's not working, but he said he can't diagnose or fix anything unless it's not working. Is that right? Shouldn't he have some tools to check parts and valves and stuff like that?
Can it be narrowed down to 1 or 2 causes?
I'm a newbie to all this, so talk slow! :)
