"We don't actually have like a prototype or anything" sigh....I guess I'm getting Mitsubishi heat pumps. lol
I recommend Mitsubishi Electric (not Mitsubishi Heavy). Extremely well made. Much better than LG, Samsung... Don't oversize it. The smaller the better efficiency. Run something else in extreme weather.
Natural gas heating is definitely not something that should be phased out in near future. It is clean, very very efficient (comparable with natural gas power plant that runs heat pump at home) and has acceptable long term footprint.
Better than oil, sure, but yeah not clean. Explainer: Cleaner but not clean - Why scientists say natural gas won't avert climate disaster
Key is "Climate scientists say that rising production of natural gas " I agree. But burning it for HEAT does not result in rising production. Burning it to get power to run AC does due to well-to-wheel efficiency. Everything has a place. Oil has place for plastics. Gas has place for heat. Even peaker plants that are hardly ever used but are very important for green grid. Just stop burning everything to get dirt-cheap electricity.
