Using the powers of nature to fight the snow, the Parikh family developed a geothermal snowmelt system that warms water to about 100 degrees using solar collectors and geothermal pumps. That water is piped underneath the driveway and walkways. The Parikhs use the sun and the ground to heat and cool the house as well. During the winter, the house intakes air warmed by the sun and carries it 12 feet underground to be heated by the ground before piping it inside.
The incoming air is also heated by exhaust air coming from the kitchen and bathroom. To cool the house, the air takes the same route; only it skips the solar collectors. Heated driveways are widely available, but they usually burn gas or oil, Raj's son Asit was quoted as saying.
"They're burning fuel," he said. "There's no combustion in this system. It's just the earth and the sun." The house also has systems to collect rainwater and the very snow it melts during winter storms. “By capturing the sun's warmth during the day, and by utilizing 2 ground-source (geothermal) heat pumps and our proprietary heat exchange system, our snowmelt system keeps the driveway shovelled- even on blizzard day,” Asit wrote on Facebook, expressing his happiness over the success of the system.
