DOE announces breakthrough in residential cold climate heat pump technology (energy.gov)

Article summary

The US Department of Energy has announced a breakthrough in residential cold climate heat pump technology, with a prototype delivering 100% heating at 5°F at double the efficiency. The new technology is expected to be deployed in 2024. The development aims to improve the efficiency and performance of heat pumps in cold climates. The breakthrough is part of the CCHP Technology Challenge, which involves several manufacturers competing to develop innovative heat pump solutions.

What commenters say

• Some commenters believe that the high cost of heat pumps is due to the 'Canada premium' and limited availability of certain models.
• Others argue that it is possible to install a heat pump for under $5,000, but labor costs and warranty issues can drive up the price.
• There is a debate about the effectiveness of all-in-one heat pump water heaters, with some arguing that they can cool the surrounding air and increase heating costs.
• Some commenters suggest that waiting for the new technology to be deployed may not be necessary, as current heat pumps can still provide efficient heating in cold climates.
• The use of backup heating systems, such as wood stoves or propane heaters, is recommended for extreme cold temperatures.
• Ground source heat pumps are also considered a viable option, with a 26% federal tax credit available in the US.
• The choice of heat pump model and installation method can significantly impact the efficiency and cost of the system.
