Old way is load the crap out if in the morning and hope I get home in time to refill before it gets too low.  Is it strange I think college is making the kid dumber than ever? 

God, please have mercy on us as this new generation takes over.  May you bless me with the knowledge to create an app to remind the moron to put wood IN the owb and accept that THIS is what keeps the house warm.  Forgive my unending cussing at how lazy and stupid these kids are now. Amen.

Oh thats the whole point of college these days, dumb em down and turn em into good little sheeple. Some of the dumbest people I know have some pretty impressive college degrees.

Minus 13 in central Maine

-13 when I went to load this morning at 6 am because the water temp had dropped to 160. I loaded at 10pm last night full. Big coal bed in the bottom but it wasn't keeping up with the run times on the indoor furnace. Right now we are at -2 and I have the house at 68 degrees. Fan on the furnace is running for 10 minutes and shutting off for only 6! With a 180k btu water to air hx I think that I am using somewhere around a whopping 120k BTUs an hour! Holy smokes.

If your heat exchanger is rated for 180k I highly doubt you are getting that out of it most of them are rated at 12-15 gpm and pushing 1800 cfm. I just installed an 80k btu brand new ecm motor furnace that has a max cfm rating of 1555 cfm on high speed.

Ultimately you are right. The Coil is rated at 200,000 btu @2700 cfm @ 23 gpm. I have dual 1 inch pex lines running to the coil and back to the boiler. I am running a Bell and Gossett NRF36 on speed 2. Run is 100 feet each way. I think that I am moving somewhere in the range of 15 gpm. My furnace blower is running somewhere in the range of 1200-1400 cfm I believe. So ultimately it would probably be more realistic to say that I am looking at likely 120-140k btu. Even at that output I am still eating up 80k-100k btu an hour.

That sounds about right especially if it was -13 outside. That's cold for anyone! I know my blower on my furnace was coming on more than usual to when it was -17 here but I also have radiant floor in the basement that radiates heat upstairs.

I wish they would rate these coils at more realistic numbers when it comes to cfm because I don't know of any residential furnaces that move 2700cfm

This is the chart that I have always used http://www.heatexchangersonline.com/airtowater.htm

Seems pretty well done but I don't know why they have such high cfm though either.
