Geothermal 101

Beneath every building lies a stable source of thermal energy. Just a few metres down, ground temperature stays relatively constant throughout the year - cooler than the surface in summer, warmer in winter. Geothermal systems tap this stability through ground loops and heat pumps.

How ground-source heat pumps work

Vertical boreholes or horizontal loops circulate a fluid that exchanges heat with the earth. A heat pump upgrades that energy to useful temperatures for heating or rejects heat into the ground for cooling. Because the source temperature is stable, the heat pump operates far more efficiently than air-source equipment exposed to extreme ambient conditions.

• 3-5× more efficient than conventional electric heating
• Single system for heating and cooling
• Long equipment life with minimal outdoor exposure
• Ideal for residential, commercial and institutional scale

When geothermal makes sense

Geothermal shines in projects with sufficient land or borehole access, long operating horizons, and a desire to minimise carbon and running costs. GeoFlux has deployed systems from 75 kW luxury residences in Gujarat to 140 kW institutional retrofits at 3,500 metres in Ladakh - proving the technology adapts to diverse Indian climates and constraints.
