Groundbreaking - Goodbye Fuel Oil

We've gotten a bit of a windfall, so we've decided to switch from fuel oil to a geothermal system.
Last year we paid CAD$3,000 for fuel, which isn't likely to go down next winter nor the winter after that.. Electricity bill will go up a bit (running the compressor for the heat exchanger), but we'll still be way ahead. Also our 200 gallon indoor fuel tank "expires" next spring, and that would've been a big production and expense to replace.
Oh, and because we had an official energy audit done, most of the improvements we make within a 9-month period will also get us a couple of thousand dollars in rebates from the provincial government.
We've mentioned it to a few of our friends, and I'm surprised at how many of them have a geothermal system too. They're totally happy with it.
Having the same hardware give us air conditioning in the summer is just a bonus. :thumbup:

This system will use our existing forced air duct work. I expect the footprint of the new system to be about the size of a refrigerator, half of the furnace we have now. This also means that our chimney will be mainly decorative.
And the insurance premiums will be lower.

Last Monday, the crew blew cellulose insulation (on top of the fiberglass batting) to bump our attic insulation up from R20 to R60.

This morning at 9 o'clock. My house is the white one on the left.

This is why I have not been diligent about mowing the lawn.

Red mud typical of the land along the Northumberland Strait.

They'll be going down 300 feet for the closed-loop piping, and it is estimated to take until 5 o'clock or so.
Unless they run into rock.
At the top they'll dig a sloping trench from 6 foot deep up to a bit below the dirt line at the bottom of the foundation wall. The rest of the equipment will be inside, so it'll be pretty much invisible from the outside, unlike a mini-split system.

That drill rig reminds me - I have a dental appointment in 10 minutes. Bye!

BTW - That dead flowering crab tree hanging from the hook is for the chickadees to perch on when the feeders are up.
 
We were able to convert from oil to gas back in 2010 and whenever oil is over $2.50/gal I'm saving nearly 50% in energy costs.

Changed the dryer and stove/oven over to Gas as well and save even more vs. electric appliances.

Would love to go geothermal too!
 
Will be interested in how it all goes. That's a pretty high latitude for a geothermal system, but it's going down 300'/91 m, and those that had problems were a relatively shallow horizontal loop not far below the freeze line. At $3,000 a year CAD for heating oil, a geothermal system certainly sounds more cost effective.

My neighbors system paid for itself in half the time they were quoted. Good for you!
 
We have a relative that installs geothermal systems and he is booked solid and has been that way for several years. His only problem is finding help to keep up with the demand. If we lived in an area that would allow it, I would be the first one to install a system. They work and are a proven money saver.

Very cool
Keep us posted. Especially on future costs

They have drilled too deep, and awakened one of the Great Old Ones - Kassogtha (aka "Bride of Cthulhu" and "The Leviathan of Diseases").

Fortunately, they did not hit water or bedrock.

Yesterday we got a waiver (not exactly a permit) to allow the electrician replace the 100 amp breaker panel with a 2OO amp one.

Today I phoned the power company to get a work order number for them to interrupt the service when the electrician does his thing.

... If we lived in an area that would allow it, ...
Are you in, uh ... Texas? ... Pennsylvania? ... Saudi Arabia? ;)

No, unfortunately all utilities are underground and moving them along with everything else that would have to be done just to drill would be crazy expensive.
 
Aug 30 update.

Basement walls got sprayed with foam insulation, then sprayed with a fire-retardant coating.

The bottom bit has to remain exposed so that moisture is not trapped.
The foundation wall itself is rock and concrete on three sides, at least 3 feet thick.
The fourth side (left side of first photo) is poured concrete topped with 2x6 studs and thick boards for the top 2/3.

To Do:
  • Electrician to install the upgrade to 200A service
  • Trench and piping from ground loop* to inside
  • Fuel tank emptying and removal
  • Furnace removal
  • Mods to existing ductwork
  • Geothermal heat exchanger and blower installation
* I almost hate to say "ground loop" because that's a design flaw in electronic amplifier systems. I don't know what else to call it, since it's not really a "well".
 
September 3, a new crew today.

Out with the old unit ...

(Well, not that old. We put it in when we bought the place in 2001 to replace the old wood/fuel combo furnace.)

... and in with the new:

Note the footprint, which is about half that of the old furnace.
After they leave I will duct tape the blue camping foam bumpers onto the corners of the duct work again. They have saved me from quite a few bleeding foreheads.

Our brick chimney (left) will become purely decorative.

They have not yet emptied and removed the 200 gallon fuel tank (at rear, centre), but I suspect that will be a specialist crew.
Woo-hoo! even more floor area made available for a workbench or something.

Here's a cool thing they brought with them. It's a charger for their cordless tool battery packs, with a built-in radio and Bluetooth speaker.

Oh yeah - SWMBO phoned up the fuel delivery service to cancel our account. She said it felt weird to do it. The guy said "Yeah, a lot of people are doing that. It's more efficient."
 
Question about your tank removal. You paid for that fuel. Can you pump it out (into appropriate containers) to give to your neighbours? Do you get a refund? Just curious. My wife wrote off her car once, days after it was filled up with gas. I got the wrecker to give me $30.00 because he had already done what I planned to (siphon the tank).

+1. Interested in hearing about this, too. We used to sell unused diesel for huge generators (the size of semi-trailers) back to the fuel company, but it was a month or less old.

I was just down there again, and noticed that you could still see the outline of the even older furnace that we replaced in 2001. It was double the area of the furnace that was just taken out.
I'm guessing that soon they'll be the size of a microwave oven. Maybe a small modular molten salt (nuclear) reactor, also providing electricity. It'll run off of the Americium 241 recycled from smoke detectors.

Very interesting! Though a proven technology, it is a cold place ... Mayhap you can also burn wood? For a cheery winter scene?

I don't believe it's possible to sell it back to the supplier. They probably have liability concerns for product that they cannot guarantee has been properly stored and handled. It's probably not worth running handling that relatively little amount to send to a refinery either.
As far as pumping it out to give to neighbours goes, our insurance company would probably have a conniption. Fuel spills are a big deal.

The year-round temperature underground where the closed loop reaches is something like +6° to +10° C, which is warm enough. There is a bit of seasonal variation, but at 100 m or so the slight temperature min and max lags behind the air temperature by 6 months, so it's warmer in winter. Even in a permafrost zone like the Arctic, it eventually warms up if you go deep enough (in mines, etc.).

Everybody that I've spoken to that has it around here is perfectly happy with their system, and have no need for auxiliary heating. On couple we know just sets the thermostat to 21° C and leaves it there year-round.

If I had a fireplace. That would be nice.
The closest we get to that is bringing out the vintage oil lamps when the power goes out during a blizzard.
