I am working on a virtual greenhouse and I am trying to make it self sustaining. For this i need to know how much it will cost to install a geothermal system on a greenhouse that has 22,500 sq. ft.

M W asked:


I’m in upper-New England, which has extreme temps. I’d like to make sure that the geothermal system being built w/ my home is a sufficient source of heat so that I must rely on a secondary heat-source only in emergencies.

Also, if the system is advertised as “geothermal-heat” does that mean I should request having a/c added, that the system will not be set up to cool my home?

Thanks.

mcg asked:


Our home is in Minnesota and was built in 1907. We heat our house with a gas/forced-air furnace (less than 10-years old) and seek information on how we might retrofit to a geothermal heating and cooling system. How much a pool or coil is needed per sq/ft of heated/cooled interior space ? Is the installation expensive?
