    At that price you would be better off with a high efficiency gas furnace. Is that Natural gas? Payback will be a long time with that gas price being so cheap. Just my .02

    What will they be using for freeze protection?

    methanol?
    ethanol?
    pg?
    enviranol?

    There are differences in design for each, and is important to know.

    What is your TESP?

    Well, if you are using a certified company, and they are using the geolink pipe from waterfurnace, they should be offering a 55year warranty.

    It goes with all of installs.

    Its methanol. I'll start looking around to understand the differences. And the installer will be using the GeoLink pipe, so we're good to go on warranty.

    In your annual cost projections do I understand correctly that on the 2nd to last page of the posted anticipated costs, we are comparing an ultra high efficiency water furnace unit to a 92 percent furnace matched with a 13 seer A/C system (heatpump). I think the costs would be closer if the efficiency levels of the gas furnace were bumped up along with a higher efficiency A/C unit. Once that is done, run your costs.

    Also in 15 years maybe 20 years what would the cost be to replace a geothermal system compared to a high efficiency conventional type system. If you have natural gas on site you should be using a gas hot water heater.

    I know you love the Geo system, but it appears you are not comparing or mating it with a system that could be more efficient than the one he used as a comparison. Also you really need to weight the costs of the replacement unit you WILL need in 15-20 years. That all comes into play.
    Why are they not using vertical loops? Is not The earth warmer vertically.

    If you bump up the conventional systems efficiency then figure what you will be saving annually then add the cost of a new Geo unit (replacement) down the road you may find you are spending more on the Geo system.

    2800 sq = 2-ton of cooling seems low to me. Does the company install conventional type systems? or do they specialize in geothermal?

    My Water furnace rep once told me they do not hit a geographical location that has natural gas. Maybe this has since changed, but a buck twenty five for gas is pretty cheap.

    Why

    Geo Therm is too expensive and the price of your gas is good. You will need to replace that unit before it pays for it self. They also need more maintenance. Give your head a shake and get a quote on a high efficinent boiler or furnace. Unless you have money to burn.
    Do it right the first time.

    Post GOOD DECISION!!!

    I hope all of this talk doesn't make you think you made a bad choice. Every
    opinion on here is just that - an opinion. You did your homework very well and made an informed decision that you will not regret! Go GEO!!!

    I was wondering how long it would take you to find this Dan. I get the 55 year warranty for all my hard work, right?

    Check-Up

    Hey thenuke, I also live in Northeast WI and am looking into geothermal systems for new home construction in the beginning of September. Also, where I'm at we can only get LP. I was wondering if your happy with your system 3 years later? And if you could offer in advice on geothermal systems and new the home building process because this is our first time around? THANKS

    I just thought I would share the details of the proposal (minus price of course) with everyone to make sure I can post the results of the install on the wall of fame and NOT on the wall of shame.

    Location: Outside Green Bay, WI
    Home size: 4913sq ft TOTAL - 1st - 2028sqft 2nd - 857sqft Basement - Unfinished, will finish later!
    Orientation: Facing North, most windows on South side
    Insulation: 2x6 with R-23 BIBS, R-50 attic, foam attic seals, foam box sills
    Heat Load: 60,189Btuh
    Cooling Load: 25,077Btuh
    Electric Cost: $.12
    Gas Cost: $1.25

    Proposed System:
    WaterFurnace Envision ND049 ECM
    12 60' trenches @ 8ft depth w/ 500ft of slinky in each (6000 total feet)
    Electric auxiliary internal duct heat 8kW
    Envision ND dual capacity Series Water Unit
    Electric with GeoAsist Water Heater
    3 Zones
    RenewAire ERV

    Heat calc and job info attached for your destruction.
    - Loop seems kind of fat, and WF unit seems kind of small, but I don't know jack, and all the math seems to work, let me know if I'm nuts.

    Thats great news !!

    You'll start seeing a ROI in about 20 years right when its time to replace the condenser !!

    J/K

    I loves me some Geo Thermal.
