I am considering putting in Geothermal. I was going to wait but some of the tax credits are expiring.
I have a 4 ton AC now with natural gas heat we really don’t use these we use theses much we use our mini splits.
I bought a tractor with a backhoe.
https://ecorenovator.org/forum/lawn-...-1710-tbl.html I want to dig my own loop field. I know it will take longer but I am ok with that we still have Mini splits so it does not have to be a fast install.
I wanted to keep my natural gas heat as backup heat but I talked to a couple installers here and they say don’t do it. They said it will kill efficiency.
I have been thinking about the system and would like some advice.
Going with a 4 ton two stage system.
1.) Pressurized or non-Pressurized system? Which one is better? I have read non-Pressurized is simpler to purge and fill?
2.) Slinkey loops or no slinky loop? I have been thinking about doing slinky to not dig up as much pasture but I am not sure.
I could do it just with a 10” trench since I have a backhoe.
3.) What system to get? I have been thinking of maybe getting a climate master system water to air it will be in my crawl space. Are there better brands?
4.) Loop field I am seeing 600’ each loop ¾” pipe with 4 loops for a 4 ton system.
5.) I have never done duct work I might contract that part out.
Looking for some feedback I have been reading but not many people dig their own system for every thing i read do it this way I also read do do it this way.
