How Geothermal Heat Pumps Work - Simple Diagram Explained #118139 (License: Personal Use)

This hand-drawn illustration depicts a residential geothermal heat pump system, where fluid circulates through U-shaped pipes buried underground-where temperatures remain relatively constant year-round-to absorb or release heat. In winter, the system extracts warmth from the earth and transfers it indoors via a heat exchanger; in summer, it reverses the process, moving indoor heat into the cooler ground. The red and blue arrows indicate hot and cool fluid flow, respectively, with “HOT” and “COOL” labels clarifying thermal zones.

This image is commonly used on educational or HVAC service web pages to explain geothermal heating/cooling basics to homeowners researching energy-efficient alternatives. It supports user intent to understand system mechanics before investing in installation.
