Heat pumps are a climate-friendly of heating a home. Replacing F-gases with propane as a refrigerant in heat pumps makes them even more climate-friendly, but presents some technical challenges. In particular, the goal of reducing the amount of refrigerant to less than 152 grams for safe indoor use requires smart solutions beyond simply shrinking the unit. While engineers are still figuring that out, outdoor units that use propane are already on the market. A flow temperature close to that of gas boilers makes them suitable for buildings that couldn't previously convert to heat pumps. Join Geoff's voice avatar and Bosch engineer Markus Sundbrandt as they explore how propane can accelerate the transition to decarbonized heating.
