Alphabet spin-off Dandelion has rolled out Dandelion Air, a combined heating-and-cooling system collecting energy from the earth under people’s homes. The company claims its kit is four times more efficient than any furnace currently in the market.

Based on a 2,500-square-foot Victorian-era home in New York state running on heating oil, Dandelion calculates that a household could save between 20% and 60% on energy costs per year.

In late-2017, the company struck a deal with the Rhinebeck, NY, council to offer geothermal to homes by installing to install ground loops on property alongside streets in front of homes. The loops are underground pipes containing water that transfer heat from the ground to a home.

Just a few hundred feet below the surface, the temperature is stabilises between 10°C and 16°C.

Dandelion has developed a small, fast drill that can install ground loops at significantly lower cost than a conventional drill.
