ThermoLift advanced Vuilleumier Heat Pump. HVAC product manufacturer ThermoLift, also in partnership with ORNL and the DOE, is developing an advanced Vuilleumier Heat Pump to provide heating, cooling, and hot water all from a single device. 
After successfully demonstrating efficacy in earlier prototypes, ThermoLift is now focusing on cost reduction. Heat pumps typically drop in performance in cold climates, but ThermoLift announced successful tests in November 2018, achieving COPs of 1.31 to 1.61 for temperature ranges –13° and 68° Fahrenheit, respectively (figure 13).
