You must have very mild winters and/or cheap electricity. Here in central New York, I've checked out many new, well insulated homes with geo-thermal. Average cost to heat mid-winter is about half of what the same house would cost with oil heat ( at current fuel and elec. prices). And, that's not including the investment in the installation and equipment. Average well insulated 2000 square foot home here uses 1000 gallons of oil for a winter with a cost between $3000 - $4000. Most geo-thermal homes are doing it for $1500 - $2000 if they are very well insulated.
Here - with geothermal - it takes 1 KWh of electricity to make 12,000 BTUs of heat. All the installations I've looked at have either 4 ton or 5 ton pumps. All also have to have some sort of aux. heat besides the geothermal - especially when temps get down to 10 or 20 below.
Electricity here - when you factor in all the added charges and taxes comes to 18.5 cents per KWh. Right now, heating oil costs $3.50 per gallon. That comes out as:
Geothermal value - $1 buys 64,850 BTUs of heat with an extra heat source needed in very cold areas. This is with an advertised electric cost of 12.5 cents per KWh that actually costs 18.5 cents.
Oil heat - $1 buys 29,700 BTUs of heat at 80% efficiency and a $3.50 per gallon price.
Propane heat - $1 buys 27,000 BTUs of heat at $3.20 per gallon and 95% efficiency.
Firewood heat - $1 buys 88,000 BTUs of heat with 70% efficiency and a cost of $200 per full cord of hardwood.

Today's Featured Article - Tuning-Up Your Tractor: Plugs & Compression Testing - by Curtis Von Fange. The engine seems to run rough. In the exhaust you can hear an occasion 'poofing' sound like somethings not firing on all cylinders.
