I am new to the forum, and am very happy to have found a place where I can talk to and learn from some intelligent people on these topics. Most people today are just zombies without brains or the interest to use them if they have them!
My problem: I had installed a Harman 2500 wood/coal hot air furnace and an A.O. Smith power vent LP water heater. A Hilcoil loop was also installed in the furnace. The contractor says he installed everything according to specs and instructions, but the hot water tank pressure relief valve is always blowing. He did put in an expansion tank hoping this would solve the problem, but it didn't.
There are only two adults in the house.
I was told by another contactor that pressure relief valves get stuck all the time especially if they are used a lot - and using well water. If it gets stuck and won't go off, the whole thing will blow up in my basement and I could even have a resulting LP leak too which could cause a fire. Is all this true and/or likely??
Of course, now I am very worried. The contractor is willing to "make the job right", but he is out of ideas. By the way, even though the relief valve blows, the water heater still fires when someone is taking a shower.
I'd rather not
put in a section of radiator to draw off the extra heat from the water since there is nowhere nearby that needs the heat and I don't want to waste it.
If I have to, I'll put a circulator in, but I really didn't want to be electric dependant and wouldn't I have to put in much bigger lines to compensate for decrease flow due to the obstruction of the impellors of the circulator when I must depend on gravity to move the water during an outage?
I live in Honeoye, N.Y. near Canandaigua. Can anyone come out and look at my set up?
Thanks. I'll be anxiously awaiting some advice.
