Half way through the article the author is touting how these can work in cold climates like Norway, then their example homeowner immediately states they have this but also they still have a furnace for when it actually is cold. Why do journalists try to pull crap like this? Contradictory information in the same paragraph!?
If you have to have a backup it is _not_ a replacement and it will not get us off of carbon. Most people cannot afford a heat pump system much less a heat pump _and_ a furnace. Heat pumps seem great for moderate climates but it is not gonna happen up north where things actually get cold and stay cold for long periods of time.
Anyone who actually has experienced this type of cold would run in the opposite direction of a heating technology that produces less warmth the colder it gets outside. Literally the opposite of what is needed for existence.
