    Thanks tecman. I noticed a common theme of sizing based on cooling. I could easily see that working in the south, but not so much in Michigan. You mentioned the ClimateMaster 8 KW. Is that only...

    Geothermal Sizing Does Not Make Sense

    I have been reviewing three different quotes on a geothermal system, but I'm not sure that any of them make sense for my house.

    We currently have a 3 ton A/C unit (3 1/2 ton coil) and a 110,000...

    Rickochet: Thanks. I have received quotes from three professionals. They all seem knowledgeable, but their recommendations on open loop vary widely. Anyway, I'm taking the water to be tested and I'm...

    Tecman: thanks for the feedback. My hope was that a plate and frame heat exchanger would not only isolate the geothermal system, but also be substantially easier to clean. I just don't know if they...

    I can dump water very conveniently. We have a high water table and soil is all sand. Even if I dumped it behind the house in the woods, it would disappear almost immediately and go right back to the...

    Thanks for the reply. I am not opposed to a closed loop system, but it's really not in the budget right now (perhaps a year or two). However, due to a failure, we need to replace at least part of our...
