Stephanie and I will make a trip this week to see the differences in possible window selections. We hope to to with Kolbe & Kolbe, but will look at the Best Build brand as well.
Tom feels that running gas to the house will be cost prohibitive. As an alternative, we will use electric throughout. Most likely a tankless electric water heater in conjunction with the Geothermal, which looks like a real possibility. One real nice advantage to the Geothermal is the heated pool year around.
