New Geothermal Heat Pump Uses 50% Less Energy

Working with ClimateMaster — a leading manufacturer of geothermal and water-source heat pumps — the US Department of Energy’s Oak Ridge National Laboratory has achieved a breakthrough in technology to create a geothermal heat pump called the Trilogy 40 Q-Mode™ that can provide residential heating and cooling as well as all domestic hot water needs. It consumes at least 50% less energy than conventional equipment and is about 30% more efficient than any other ground source heat pump on the market.

A conventional geothermal heat pump pulls heat from the Earth and uses it to warm up your rooms and your domestic hot water. When you need to cool your home, the pump pushes heat from inside your home back into the Earth. To learn more about how heat pumps work, watch the video above.

The Trilogy series geothermal heat pump is a bit different. Instead of just pushing or pulling heat around to cool or heat your house, it also uses that heat to provide 100% of your domestic hot water all year long. Conventional ground-source heat pumps can only generate hot water as a by-product when operating to heat or cool your home and typically supply less than 30% of your annual hot water needs. ClimateMaster is producing the Trilogy 40 Q-Mode heat pump at its factory in Oklahoma City.

The Energy Department’s Office of Energy Efficiency and Renewable Energy accelerates development and deployment of energy efficient, renewable energy technologies. It has recently completed a project in conjunction with Ball State University that will save the school $2 million annually in operating costs and cut its carbon footprint by nearly 50%.

Geothermal energy has benefited mankind for millenia. It was used by the Romans to heat their famous baths and by Paleo-Indians to cook their food. Now it can be used to heat and cool our homes more efficiently than anyone ever thought possible, thanks in large part to the researchers at the Oak Ridge National Laboratory.
