    Ground Source Heat Pump in Cold Climates?

    I work with a mechanical contractor in southeast Idaho. We have done a lot of radiant homes and snow melt systems over the past several years. We were just approached by a homeowner that wants to do a radiant heat system using a ground source heat pump. this system would also be used as their coolong system in the summer. We've never installed one of these systems before. We were hoping that someone could help us witrh a few questions we have. How well do these systems work in a climate that gets to
    -20 in the winter. Are they that efficient versus the investment, or would a radiant heat system with a high efficiency boiler be a better option?

    thanks in advance for the help.

    go for it

    size units accordingly, don't cheap on the loop fields. there is a never ending supply of btus in the ground. Econar equipment is a good choice. I know there are others out there too. Econar will help you and answer your questions.

    Todays snowfall 5-8 inches. Where was the snow during christmas and new years time? oh well, we enjoy the snow when it falls.

    Have a good day.

    geo

    You can install water to water geothermal units. I believe the highest water temp they can make is 120°. Usually a storage tank is used so you get consistent supply temp and long run times. For cooling you can use separate units or use the water to water units to make chilled water. Then you have the chilled water piped to some type of fan coil units. The control system can get interesting.
    As for payback it will depend on the costs of electric and whatever else you would use.
    Often times it depends on some other reason the owner gives. Like I don't want to worry about propane or oil deliveries or I don't want to see condensing units around my house.

    We have done

    about half a dozen Radiant/Geo homes here in Iowa.
    The last one was 7000 sqft finished with 3 stall garage.
    Twin Water to Water units, 50 Gal buffer tank, Air Handler and 19 zones. (including the Garage) Last month it cost $156.00 to heat the home and garage.

    Before you get into this job I would recomend getting certified in geo AND get the factory training!! The Geo side is a different beast and MUST be set up properly.

    If done right Geo will give you the MOST efficient heating and cooling and very little service. We have been doing Geo for 5 years and I have only had one service call on more than 50 units! (A leaking schraider(sp?) valve)

    Yes you can

    install Geo in Idaho...Geo units have been installed 114 miles North of the artic circle and within 1 Deg of the Equator.

    Before you take on this project get IGSHPA certified for Geo. Then get the manufactures training. Geo is a different beast and MUST be set up properly. If done right Geo will give you the MOST efficient source of Heating, Cooling and Hot Water available. In the 5 years we have been doing Geo I've had ONE service call...for a plugged filter.

    We have installed more than 50 units during the past 5 years. Of that, about half a dozen are Radiant installs.
    The last Radiant job was 7000 sqft finished with a 3 stall garage. The job has twin water to water geo units, a 50 Gal buffer tank, Air handler and 19 zones (including the Garage).

    Good Luck

    take a course. even if you can't get to an IGSHPA one at least take one of the many manufacturers courses available, there are many little details to know before you do a system, don't become a geo casualty.

    buffer tank

    Last water to water that we did was an 8 ton. Mfg, Econar, required(suggested) 80 gallon tank. 10 gallons/ton seems to be standard size. Your job of 7000 ft. would require 10-15 tons in my neighborhood. How does the system work with a small tank?
