True or False: Geothermal houses require only 15 degrees to be warm or cool enough for comfort.

Geothermal houses indeed typically require a minimal temperature adjustment, often around 15 degrees, to achieve comfortable indoor conditions. This efficiency stems from the way geothermal heating and cooling systems work, utilizing the relatively constant temperature of the earth below the surface. The ground maintains a steady temperature year-round, which means that heating or cooling the air inside a geothermal house can be significantly less demanding compared to traditional HVAC systems.

In moderate climates, this system shows its true potential, allowing homeowners to maintain comfort with minimal energy consumption. The reason for this limited adjustment in temperature is that geothermal systems can harness the earth’s thermal energy effectively, making them ideal for achieving comfortable environments without the need for extensive heating or cooling.

Thus, the assertion that just a 15-degree change can provide sufficient comfort in geothermal houses is valid, reflecting their energy efficiency and suitability in diverse climates.
