General Outdoor Furnace Discussion / Re: Over Pressure?
« on: November 01, 2013, 01:13:17 PM »
I have one expansion tank in the house and one outside...do you think one more? not exactly sure if the two i have work together or not...
also, i have put less wood into the furnace (just enough to get me 12-14 hours of burn time) and i havent had it blow off again. more evidence of possibly over loading the stove?

Gentelmen,
Thanks for the replies, I have had the expansion tanks checked by a plumber and he says that they are good. I will have to agree that i think i'm just running it too hot. I found out that my mother in law has been loading it during the day.
My other question is...If there is not a demand for heat, the unit should just sit and smolder right? and if it is reaching a certain temp and causing the PSI to push past 30 causing it to blow off, should i lower my PSI to say 16 or 18? (if thats even possible)

slimjim,
thanks for your reply, I replaced the door gasket and the gasket between the blower, I have not replaced the gasket on the ash door but i could not see or feel an air leak (i will replace it tonight).
the aqua-stats are all analog and do not give me a reading. the only place i see an actual temperature and pressure reading are on the front of the stove and in the house near the oil furnace. Is there another way to check the temp without replacing parts?

disclaimer...i am completely new to the entire outdoor wood furnace/boiler scene. We just bought a house (over 5k square feet of heated space), the house has a boderus furnace (oil) in the house and outside has an Aqua-therm sheltered wood furnace (not sure of the model).
Here is what is happening. the furnace temp is set at 190 (back of the furnace) the aqua stat that is inside the house (the overtemp one that redirects to the attic in case of overtemp) is set at 195. Any other settings and the furnace will vent out of the over pressure vent. The previous owner had it set at 195 outside and 200 (max) on the inside. when the system is running the pressure in the system is 20 psi inside the house and 22-24 psi outside at the furnace.
I have replaced the pressure relief valve (i should say, my plumber has replaced it) and he has looked over the system and can come up with not other reason why it would be venting off at those temperatures if the previous owner was able to run it at those temps.
Am i missing something easy here? I'm sure i have not given all the info needed and i appologize in advance for not knowing all the nomenclature.
