It gets better.
You see the idea of getting all rooms exactly at 70C is overrated. My upstairs bedrooms are about 55F in the real cold, maybe even cooler. However, I got Swiss Duvettes (comforter) on Overstock REAL cheap (goose down, fill 700 -ahh) and now understand why Central and Northern Europe design
houses so that the bedroom are 55F. Getting up for a night time leak can be a little challenging. I even sleep with the window open a crack as my wife is a fresh air fanatic. Tightly sealed houses are a health hazard par none - trust me or google it if you don't believe me. Oh, I still have my oil fired CH if all else fails but I only turn it on if hell really does freeze over. It gets better. Come spring I unhook the stoves, take out the powervent, clean everything up and shove it in the corner and slam a piece of cheap plywood in the hole, seal edges with chewing gum (whatdoya mean caulk it), you chew the gum and reuse - no humidity problems, no rust and now the heating system takes no space. Now what did I do with the space well I found http://www.byo.com
and bought a couple of units and turned it into a bar. The beer is very cheap to make and let me tell you guys it is very, very good! Funny, my neighbors suddenly became life long friends and I got invited to more BBQs (free food) - I suppose I should start charging.
Following my fine example you too can become a useless, degenerate drunk - it's not that hard.
LOVE this stuff.
