Heat pumps become inefficient when the temperature gets real cold. I have had heat pumps in my home for 47 years. Most homes that have heat pumps have backup heat strips. I can tell by watching the meter spin when those strips are activated.
That is why the portable heat pump that I referenced is a single hose unit that draws air from the INDSIDE of the coach and exhausts the cold air out the single hose to the outside, while blowing the warm air in the coach. It is unaffected by outside temps and maintains it's efficiency all of the time.
They do make portable DOUBLE hose heat pumps that draw air from the outside and also exhausts air to the outside. These units are like a rooftop RV heat pump or a residential heat pump with a pad mounted compressor.
They also make ground coupled heat pumps that are connected to the earth, or a body of water, that will continue to operate efficiently in all kinds of weather, without heat strips.
Technology is improving all of the time and what was happening 10 years ago is not longer relevant.
I went and took a look at that A/C - Heat Pump. That really looks interesting.
