in cool climates, space heating is the largest slice of the energy pie.

this makes sense, for a few feet near the water heater.

warm air rises. that heat is more likely from warmer underground soil.

why not warm the house with escaping flue heat? or do you mean ducts?

maybe $2. everything fails, even a 7,000 hour cf vs a 750 hour incandescent.

goody.

in phila, we pay about 15 cents/kwh.

if you run 10 15 w cfs, it's $2/month. why waste money and energy?

good idea, for a small room, or a heater under a desk.

do they use more power than fridges?

your freezer uses $35/30/0.05 = 23 kwh/day? recent fridge/freezers
use about 400 kwh/year, ie 1.08 kwh/day. last week, my supermarket
was selling porterhouse steak for $10.25 a pound, but every month
or so, the price is closer to $3...

would you hafve any evidence for this article of faith?

>sorry you can't buy a new one like mine, any more.

why would you want to buy a 40 watt 3 ft^3 fridge, when an 18.8 ft^3
energy star fridge/freezer only uses 1.08kwh/24h = 45 watts? :-)
