Geothermal Heat Pumps
2025-02-19 12:00 - 13:00 (America/Los_Angeles) | Online
Join us on February 19th as we explore the world of Geothermal Heat Pumps (GHPs), a technology that harnesses the constant temperature of the shallow earth to provide heating and cooling. Because the ground can absorb excess heat during the summer and act as a heat source during the winter, GHPs are extremely efficient—reducing energy consumption up to 44% compared to air source heat pumps and 72% compared to standard HVAC systems. While more costly to install, GHPs offer greater longevity and stability than air source heat pumps, and the additional costs may be returned in energy savings in just 5-10 years. We’ll discuss which climates and conditions are optimal for GHPs, and how to decide if your property is a good fit. Our panelists will share the basics of geothermal heat pumps along with their many advantages—high efficiency and extreme climate performance to name a few. Join us for a 45-minute webinar in which we’ll discuss: What is a geothermal heat pump and how does it work? How efficient is a geothermal heat pump, as compared to other types of heating and cooling? What are the benefits of using geothermal energy? Why would someone invest in geothermal versus an air source heat pump? What is the cost to install a GHP (and how does the energy savings impact payback time)? Are there incentives available? What is the lifespan of a GHP system? What are the ideal climates for GHPs? How can geothermal energy help the grid? How do I decide if my property is a good candidate for a GHP? What about larger buildings or multifamily buildings? What are the different types of GHPs available? How can I find someone to install a GHP at my home?
