What kind of marketing strategies are being used to move geothermal products around the country? I'm curious if anyone has completed market research showing the characteristics of the typical geothermal customer. I installed an ECR DX system in the Dallas area for a new home in 2007. I have begun using a TED to track kwh and costs of the geothermal via their PC interface and it's averaging around $1 day to heat this home. So far, this is in line with the Manual J numbers my HVAC professional prepared for me before I built this home. In short, it's working just fine. A group of us are beginning to evaluate geothermal from a business perspective and I'm just curious what kind of business thinking has gone into marketing goethermal.
