pumps? i thought heat was transfered by convection = ie. natural tendency for warmth to move in the cold direction... hot roof transfers heat into ground - hot ground transfers heat into home heating system... ?

i suppose you could use solar power for the pumps.

If you are off-grid, the geothermal system uses too much energy for the solar panels to handle. Unless of course you have a huge 10KW system. But then, it does not make any sense financially

While it's true that a geothermal pump uses electricity, it does so at about half the usage of a typical electrical air heating system.

"Geothermal heating uses no fossil fuels". Really? So how do you power the pump? Electricity of course. And fossil fuels are being burned to produce the electricity at an efficiency of around 30% - so your 3:1 power gain goes straight out of the window. Unless the power source is strictly hydroelectric. Very few countries are 100% hydro - maybe only Norway. Basically, geothermal heating is expensive hokum. Buy a woodburner.

A large amount of power in Canada is hydro-electric so much that people call the poles carrying power 'hydro poles' and you don't get an electric bill you get a 'hydro bill', the only exception is my small province where hydro is not an option since it's so flat here - the power in my area is 95% nuclear or gas turbine to cover large spikes in demand.

U.S. Geothermal Inc. = HTM

if you're an investor, it could pay off. and the stock is on fire this week.
