Thanks for offering to help.

I don't have much info yet.
Based on commercial geo estimates,
I need somewhere between
4 and 8 tons. I need to look again
to see if two or more are close.

I have not had a chance to run my own numbers, but gas consumption last year points to about 3 tons.
The occupied part of the house
is 2000 SF, though many areas don't
actually need heat/cool - eg, rooms
with no outside walls - never heated
before, no need now.

I have a "2 ton" unit in the
Kitchen/Dinette and a 3/4 ton unit
in the bedroom.
These are different models of
Multi-Aqua hydronic air handlers.
Give it power, it moves air,
and sends a demand for water
flow (24VAC).


The idea that I saw on this forum
and that I liked was taking a window air conditioner (and I have a few that are large), remove all the plastic housings
and insulation, and fan, and make a
storage tank around the heat
exchangers on both sides.

I have an AC that has a bad fan, so I thought I would use that, but the compressor is flakey also, so I am looking at another. This is one that some buffoon dropped on the power switch, so the post broke off. That gives this buffoon an excuse to change all the wiring.
The EER on this one is higher, 10.8 or so.


I have 2-3 options before me for ground:

As for ground, I got an estimate for the whole house, of about $80,000, including 700' of bore holes. The holes were quoted at $17,000. With Natural gas
heat, the 80,000 figure is hard to
justify.

So I got a quote from a paving contractor
to dig trenches for me to install
3 Tons worth of horizontal slinkies
(3 * 500' of 3/4" HDPE) including 6" of
sand above and below each,
for $6,000. I'm planning to ask him
to quote paving as well.


I also got an estimate (but first hand
or in writing) for a well for $4,000.
That would be for pump-and-dump.
But I still need to speak to the city
plumber about the dump part.


Other initiatives include
solar thermal collectors -
There are a few options, and
parabolic trough is ranking up there.
I'm also thinking of a flat panel
that will blend with my solar panels.

I have two 40-gallon hot water tanks.
One is electric, and worked fine
for my radiant floors this winter;
The other is gas and does not work.
(Well, my sister-in-law gave up on it).


Thanks
Seth
