    I'm investigating a geo-thermal install for our existing house.
    We're on Long Island. Currently we have a gas boiler that needs to be updated. It's at least 20 years old and has experienced a number of floods before we got the drainage problem fixed.
    It's around 1200 sq feet. Walls are heavily insulated. The floors, over a slab, aren't. I'm also looking into radiant to replace baseboard heat.
    The one contractor I spoke with thus far says the changeover, while efficient, isn't worth the expense.
    Shall I investigate further or is it pretty much true that the electrical usage that I might see would outweigh any efficiency?

    Where on LI are you?

    Here are the links I have for Geo-Thermal. You can contact them and find contractors in your area. Also ask them for any rebates that are available through Federal and State programs, along with your local utility supplier. (LIPA)

    As has been stated insulation should be first on your list.

    yea, that first message in the link kinna set me up. I think not for 10 or more years. I think I'll just update the aging gas furnace.

    Currently LIPA is giving $600.00 per ton rebate on Geo equipment. Check on there Web Site.

    At the very least consider Heat Pumps set up as a Duel Fuel. This winter 90% of your run time would have been HP. Hope it stays this mild.

    Where on LI are you???

    Sorry cant give prices.

    Lets just recap what you have.
    20 year old Gas boiler. (I assume Nat Gas)
    You stated Baseboard.
    Floor over slab. (I assume little if any basement or crawl space).
    I don’t see what you have for A/C now. (Hopefully ranch type house with full attic, We need to know)

    What were you planing to use for water with the Geo. Closed loop/Supply & Discharge Wells? Unless the water wells are in place I don’t think Geo is worth it in the short term. 7 to10 Years.

    The first thing I would do is do a heat Load/Loss on your house. (Red tab above. $50. Well worth it.)
    Make up a list of any problems or complaints with your present system, Long or short run times, Hot or cold areas, noise, drafts.

    Talk to your friends and neighbors concerning who they use and if there happy. There are a lot of contractors on LI. More then half I wouldn’t use. Get your estimates and post them here.

    Personally I would consider installing a Heat Pump/s for cooling and most of your heating. Replace your boiler with a 90+ and have the system set up for Duel Fuel. (Heat Pump supplies all heat above 50 Deg. Between 25 Deg and 50 Deg HP first stage, Baseboard second stage, Below 25 Deg Baseboard, Rough #’s)But I’m not the one signing the checks.

    There are others members here from LI that might be able to help. I’ll check my list later.

    You can contact me at aol com but please keep posting.

    Good luck

    Paul

    Thanks for your input Paul.

    yes nat gas.
    60% crawl, 20% slab, 20% basement where the current boiler resides.
    AC are 3 thru the walls. One upstairs in bedroom 10K. One downstairs on 1st floor. 10K.
    All cathedral ceilings. No attic.
    Wells are not in place. Property is small, so there'd have to be a vertical loop drilled.
    So I guess I'm done with geo? huh.

    I've called 3 contractors of some repute. By that I mean they are Wirsbo referred, the radiant manufacturing company. (like you don't know).
    Not that their referral necessarily means beans.

    What is a 90+? And what is meant by dual fuel. Or rather, what is the 2nd fuel?
