Staying Cozy & Cool: FAQs for Your Home

 A geothermal heat pump, also known as a ground-source heat pump, uses the stable temperatures found underground to heat and cool buildings. It circulates a fluid through an underground loop system to transfer heat between the earth and your home or business.

In winter, the system draws heat from the ground—which remains warmer than the air—to heat your home. During summer, it reverses the process to extract heat from your home and transfer it back into the earth. This exchange is managed by a heat exchanger and a network of underground piping.

• Energy Efficiency: They can reduce energy usage by up to 65% compared to conventional HVAC systems.
• Cost Savings: Lower energy consumption translates to substantial long-term savings on utility bills.
• Environmental Impact: By tapping into renewable ground      energy, they help lower greenhouse gas emissions.
• Quiet & Durable: Fewer moving parts mean quieter operation and a longer lifespan, with underground loops lasting 50+ years.

 Yes. Because the underground temperature remains relatively constant- typically between 45°F and 75°F- the system provides efficient heating and cooling regardless of the external weather conditions.

• Closed-Loop Systems: These use a sealed circuit of      piping buried horizontally or vertically to circulate a water/antifreeze solution.
• Open-Loop Systems: These borrow water directly from a groundwater or surface source, pass it through the system for heat exchange, and then return it to the source.

The underground loop often comes with a lifespan of 50 years or more, and with proper maintenance, the indoor heat pump unit typically lasts around 20 to 25 years.to substantial long-term savings on utility bills.

Geothermal systems are known for their low maintenance needs. Regular inspections of the heat pump and annual servicing (if recommended by your provider) are usually sufficient, while the underground loop requires virtually no maintenance.

• EER (Energy Efficiency Ratio): This measures the cooling output relative to the energy consumed.
• COP (Coefficient of Performance): This indicates the heating      efficiency by comparing the heat output to the energy input.
  Higher values for both means a more efficient system.

Absolutely. One of the main advantages of geothermal systems is their ability to efficiently provide both heating and cooling, as well as potentially heating domestic hot water.
