Reply #26: We spoke with an installer

2 days ago. We are doing this, it should pay off in 6 years. The lines will be sunk into the pond. I will let everyone know how this goes next year when the house is up and running. It sounds wonderful but it is terribly expensive. We are doing it and giving up a few other things to do it. The references we called, people who live close by who have them, say that rarely in the last 2 years since our summers and winters have been rather mild has their system had to kick in. Their electric bills are tiny. So, we will be happy to use less not only for the bills but for the environment.
