geothermal sizing

I am in the process of building my 2880 sq. ft. home. I would like to use geothermal heat with a lateral loop since I am on 2 acres I have plenty of room to make the trench. Can anyone recomend a length of inground loop for my house? I have learned about the coil method to conserve space, and since my backhoe has a 24" bucket this would be optimal. I've been told 450' but I was hoping for another opinion.

Hey Mike (newbie)

What hvac knowledge to you possess? It take a bit more than digging a hole to install a geothermal system. Time to call an expert....(they may let you dig for them)


Do you want it your way or the right way?

Hi Mike

You will need 600 feet for every ton needed for your home. So if your unit is 4 ton you will need 2400 feet of pipe in the ground

The amount of loop length varies with the trench depth, and your soil. So there is no one length per ton.
