Mac, I DID, AND added 3 new top of the line doors, 30 new top of the line triple hung thermal pane windows, 5 BALES of R38 insulation, and about 20 cans of spray foam insulation, everywhere I could get it.
It's a 200 year old 3800 sq ft house man! And with my 'stat set at 75 in my den, with TWO oil filled electric space heaters on HIGH to top it off, I couldn't get my den over 62 degrees this winter when the temp hit -30.
So this year....I'm putting insulation in the attic, and insulating the roof with that breathable stuff. 3Ming every door with extra insulating strips. Doing a little tweaking to my boiler to max it's effeciency,
AND putting in two wood burning inserts, one for each fireplace, and buring the hell out of wood to cut my fuel in half......I HOPE!
Then I'm buying a 2nd 255 gal fuel drum to hook up so I can buy 1000 gallons at once, 500 to fill them, then 500 on reserve. That gets me a lower price, so I can lock in there. All in all, I should drop my heating bill from $1000 a month to about $600 a month. Plus my elec bill will go down without the boiler and pumps working 24/7. So with the extra, maybe just maybe, I can swing a 520 next time around! LOL If the boss approves.
