THIS NEW SYSTEM HEATS AND COOLS HOMES WITH GEOTHERMAL ENERGY
11th July 2017
Google parent company Alphabet has launched a new company, Dandelion, that aims to tap into geothermal energy to heat and cool homes, reports Michael Irving for New Atlas. The technology pumps heat from the ground into the home in winter, or out of it during summer.
The roots of the Dandelion system are what the company calls ground loops. These U-shaped plastic pipes are buried a few hundred feet under the yard, and water is pumped through them to provide the heating or cooling effects. In winter, water running through the loops will absorb heat from the ground and pipe it into the home, while the system will run in the opposite direction to keep things cool during the scorching summer months. The pipes are connected to a heat pump and water heater inside the house, and users can control the indoor climate through a smart thermostat.
To install the system, the company uses it's own "clean drilling technology" to dig small holes in the yard. Users only have to change an air filter every six to 12 months for maintenance.
