What maintenance does it take other than adding a small amount of liquid in the first few years? The installer comes by in the fall and checks it out and might give it a top up. It has run flawlessly for years. The vertical pipes are pro-rated warranteed for 50 years. My geothermal system was $19,800 and included adding a cold air return duct to make the circulation better. Our house is 3,008 square feet and all I did was insulate and seal it up as best I could myself. Monthly Hydro averages $158. Go back to natural gas? Never.

I want to go away for a while and was going to set my system at 17C but the experts at Geotility said no can do as heat exchanger will freeze up ;; 19C is lowest recommended setting have you any opinion on such?
Thanks

I don't know what they are talking about. My liquid comes out of the ground at a steady 15C and goes back into the ground at 5C degrees in the winter. All the lines are heavily insulated where they come up from far below any frost in the soil.

the heat exchanger in the furnace, not talking about the ground loop line they said setting the heat too low will cause the heat exchanger to freeze up I think because your using Freon

Does your system use forced air to get the heat around the house, or does it use liquid and radiators? I don't know a thing about the liquid system. In our system the warm liquid from the compressor goes through a radiator in the plenum above the compressor. When heat is needed, the fan comes on and blows through the radiator and moves the heat through ducts and through the house. I just leave the thermostat set at 20.5C all the time and rarely change it.
I still can't figure out this freezing problem that they were talking about.

LOL thanks I dont even know of a geo thermo system thats uses hot water heat ? is there actually such?

geo thermo systems use a heat echanger and freon;;In summer it flows one way and in winter(heat it reverses)

the loop lines have water and anti freeze mix; in the summer the heat is absorbed from the loop line by the cooler earth
and in the winter the loop line absorbs heat from the warmer earth

anyhow I found out the info I was given was incorrect and I can in fact set my GT heat to 17C while I am away

ok heres some hard facts

Iam using 887 KWH per month for GT heat alone ( NOT including fan operations etc ) which cost approximately
$110 after all the bs charges and taxes etc

887 KWH is equal to 3.25 Gigs of natural gas which cost about $38


so no GT heat system is not more efficient $$$$ wise at all
