Geothermal explained.
Simply put, a geothermal system doesn’t heat or cool you home by burning fossil fuel or using electricity in the ways you’re used to. Instead, it uses electricity to access the near-constant temperatures found deep in the earth.
Geothermal work on a very simple principle: no matter what the air temperature is outside, under the surface of the earth, the temperature remains constant. Which mean that during the summer, the earth is cooler than the outside air, and during the winter, the earth is warmer than the outside air.
Vertical Loop
When space is limited, the heat transfer tubes are sunk straight down into the earth.
Horizontal Loop
When plenty of space is available, the heat transfer tubes are not as deep, and extend out rather than down.
Pond Loop
Uses the water in a nearby lake or pond to absorb or gather heat.
Open loop
Uses existing groundwater as a heat transfer medium.
