This looks like something that needs to be done before the house is built, under the foundation / slab? Or did I read it incorrectly? Either way, I had to really push on my contractor just to do a heat pump. (And there are two large areas of sand under my house, one under my garage and the other under my sunroom.) I don't know how I could get someone to build that where I live.
I also couldn't tell if this is something that warms up throughout the year, or if this is something that warms up during the day and cools at night? Where I live, the days are very short in December / January, so I'm not sure if would work if it's day-to-day instead of seasonal.
