if you dont have lots of land they can run the loops straight down.

in the USA we have a 30% tax credit on the entire system to sweeten the pot.

That is a good solution.

what is this "brake pedal" you speak of?

there are DIY kits for horizontal loop systems, uses water (a safe type of antifreeze really) through pipes you bury 5 feet under yourself (with your handy backhoe). then the compressor and such get slotted into your (hopefully existing and well insulated) duct system. pretty cheap that way. otherwise.. heh..

mine has 2000 feet of pipe 5 feet down arranged as 4 x 250 runs in my back yard. thats for a 3.5 ton unit.

if you dont have lots of land they can run the loops straight down.

I had mine done by a geothermal company. I just watched. everything is energy star rated.. even the duct tape they used to seal the ducts.

worst part was the new duct system being installed as we previously had hot water baseboard heat and no AC. so all new ductwork and holes throughout the house were cut. our cats were not amused with that part.

from 15k-30k on a new system

For some plastic pipe DIY "Horizontal air-ground heat exchanger" Earth to air heat exchange through buried pipes there is no so much costs.

You need to install pipes with inclination and make some holes for condensed water elimination.

I've been considering this for my home how difficult was it to get setup?

Call a HVAC shop and dump anywhere from 15k-30k on a new system, of course it all depends on your home square footage, heat loss, ex....

I use geothermal to heat and cool my house. when its cooling the house some of the heat removed is sent to my hot water preheat tank  (desuperheater system). then the main hot water tank is an air source heat pump that cools and dehumidifies my basement where my miners live.

the preheat tank can get to 135 F, which is higher than the 120 F normal setting of the real hot water tank. to get it to come on and cool the basement more I set the main tank to 140 and we take lots of long hot showers.

so basically miner heat is moved to where is usable; my hot water system. the rest goes out to the back yard.
