Heat pump working at 28 degrees ambient
I did an experiment with my heat pump tonight. Wanted to see at what temp it would switch to the furnace. It is down to 28 right now and the heat pump is still running blowing 104 degrees out the vent...

Probably the units have heat strips that result in blowing out the hot air once the temp drops below about 40F.
Nope, a heat pump is just a heat pump. Some older RV AC/heat units do have heat strips(usually about 5K btu's) that put out some heat but they are not advertised as heat pumps. The newer RV heat pumps are just more efficient and able to work at lower temps than the older units.
