I don’t think he ever sold it ad new tech its more of a Silicon Valley spin on old tech. And heat pump are in the US but many are hesitant because of the climate in the states can be extreme and as you said NZ has a milder climate compared to the US. for example in my state just last month we hit lows that aren’t supported by any heat pump on the market for days on end but my furnace kept me warm and on the other side of the country temperatures break world record highs every year. Everything op said fits the US market very well heat pump demand is on the rise, alot of people have smart thermostats they’re even provided by some utility companies, the product is a very compelling.
