That wasnt really my point. My point was twofold, that 1. the tech exists, so way praise google X etc? 2. Its already outdated.. air to water heatpumps are moore efficient, cheaper and easier to install. The ground based heat system require a very large yard or similar to lay pretty massive amounts of pipes to be effective. Thats also a very big part of the cost.
