I am trying to decide if my geo was installed correctly. The individual doing it has been installing these units for quite some time but my power consumption seems high. I am attempting to figure out why usage is so high (90kwh/day) for a 3000 square foot home (well insulated, great windows etc). I have tried to work on all area's to decrease my consumption but need help.
The geo is a 5 ton waterfurnace that has 1500 feet of pipe installed vertically. The installer hit limestone at 25 feet and it continued to over 100 foot. After attempting to drill one well for literally weeks (I was his first drilling job as he contracted that out before) he finally decided that multiple shallow wells would be better. So, he installed the 1500 feet of pipe into not 5 wells but 10. This obviously means my wells are not the normal depth but he said this would not be an issue as if he did a horizontal well then all of my pipe would be 6 foot in the ground. He also stated that the limestone would act like a good heatsink and therefore increase my efficiency.
What are your thoughts? Is there anything wrong with this setup? Is there a way to check my unit's efficiency ie power consumption? Thanks in advance for your help!
