Oil vs propane heat

[buckeyefarmer]

So the installation cost of Geo Thermal is similar to the cost of a TLB?

I have 2 units, a 2 ton and 3 ton. Here’s my quote for $45.5k before tax rebate. It cost me $14k plus a tractor, around $11k after tax rebate.

Are the left headers spare? Also, how many trench feet did yours take? Total pipe length if you have that? Sq footage of house? Sorry for all the questions.

The left is for my 3 ton unit that wasn’t done when I took the pic.

2ton unit $3940
3 ton unit $4292
Backup heat coils $158 and $189
Fusion kit $1100
7 x 500 ft roll SDR11 $104 each

Flow centers $624 and $949 (2 pumps)

Around $400 for propylene glycol

That’s pretty much all the costs except fittings.

Replacement flow center last yr was $760 for the single pump (2 ton) I need to rebuild the failed pump for a spare.

One 500’ of pipe per ton / loop for slinky plus 100 ft each way is to get to the slinky in the trench, so 700 ft per loop.

I put in shut off ball valves for each loop (allows you to purge each loop using the loop pump) and all the HDPE to metal fittings added up.

Their quote was to connect to existing ductwork. I moved my upstairs unit and totally redid my attic ductwork.

I also ran my own manual J to size the system.
Which I can’t find now. Close to 2700 sf. Plus basement.

Also bought manual j software and geothermal design software. Also took the IGSHPA geothermal installer course and was an accredited Installer at the time.


Slinky trenches are about 65ft long.

Before geo I used an oil boiler and forced hot air from heat exchangers. Still have the boiler in the basement, need to tear that out.

Great information, Thank you! I wonder if I can find the course anywhere or on line.

I see they now have an online course

I also put in a monitoring system.

Welserver.com

I keep track of loop temps, runtimes.

Be aware that there are also vertical heat exchangers.

When I was pricing out systems the cost for 3 wells to provide the heat source was the same as the ground loop system.

Heat controller units. Same as climate master. They use same control board.

Prices are 10 yrs old.
