Testing / What is this strange stuff???
« on: January 23, 2018, 05:24:00 PM »
My stove stopped heating and after intensive searching found this stuff at the inlet of my pump. I had to drill part of it out then fished the remainder with a wire. It is hard and looks like it folded up as it entered the 1 pipe. Its color resembles the color of my stove chemical. Anyone got any ideas???

Electronics / Furnace Fan High Limit Problem
« on: November 05, 2012, 03:04:18 PM »
I need a little help with a problem I am having with the fan on my oil furnace since I installed the Hx in the plenum for my OWB.  As long as I keep the temp on my OWB around 145 deg. everything works fine. If I increase the temp above 150 the furnace fan won't turn off. It continues to blow heat even if I turn the thermostat off. I have to turn off the breaker to the furnace and let it cool down before it operates properly. I am sure it is the high limit seeing a higher than normal temperature causing it to run.

This is what I have found so far, the fan motor has lead designations "H,MH,ML,L,C". I have wires connected to "H,MH, and C". (red-orange-white). I have currently disconnected the orange wire (or MH) and it seems to work fine. The orange wire goes to the fan limit switch.

I really don't want to disable the fan limit switch or increase the temp setting if there is another solution as it is a safety device for the oil furnace. Anyone have a suggestion??  I do have a schematic for the furnace and can post it if needed.

I plan to wrap my pex lines myself and put inside 6" pvc. I was wondering if anyone has used this product.

Their Prodex Total is 15/32 thick and claims R 15.67 insulation value.

Thanks

Electronics / Heat coil location
« on: February 29, 2012, 04:25:47 PM »
Is there any problem installing the owb heat coil in the return side of my oil furnace, as I have almost no room on the hot side? Also can I install a flat plate heat xchanger in the same loop for my dhw. I plan on installing it as the first in the loop before going through the heat coil. I have an elec. tankless hwh and would like to bypass it for winter use. Will the flat plate give me enough hot water alone without a storage tank? Thanks, I am a newbie, love this site!!!!
