Benjamin Carr, Ph.D. 👨🏻💻🧬#Lennox's new extreme cold #heatpump operates at as low as -20F
It’s called Dave Lennox Signature® Collection SL22KLV Cold Climate Heat Pump, and Lennox claims its efficiency levels are 150% higher at colder temperatures than standard heat pumps.
In 2022, Lennox was first company to complete first phase of the #US #DOE Residential Cold Climate Heat Pump (CCHP) Technology Challenge, and the SL22KLV is a souped up version of the unit developed for that challenge.
