Hi,
Heat pumps work by extracting heat. This heat pump and every other heat pump extracts latent heat from outside the RV and pumps it to inside the RV. I'm glad it works in temperatures down to the teens.
Extracting heat from inside the RV and returning the heat to the RV would be a perpetual motion device.rgatijnet1 wrote:
Unlike roof top heat pumps, the single hose heat pump draws air from the inside of the coach, and it will work just fine no matter what the outside temperature drops to. We have used ours in locations where the outside temps were in the teens.
You really need to look at the differences between the double hose and single hose portable heat pumps. The double hose heat pump will not work in as low an outside temp.
With the portable heat pump you are extracting cold from inside the RV, blowing it out the single hose, and returning heated air back in to the coach.
