Hyper Heat systems

Hi everyone, Hyper Heat (Mitsubishi) is a heat pump system, but it adds an exclusive inverter technology that allows it to maintain its efficiency when temperatures drop, apparently all the way down to -13 degrees F… We are looking at ditching our old and rusty boiler to solely rely on a new Hyper Heat system and solar panels. Looking for feedback as solely relying on Hyper heat systems for colder days is a fairly new trend…
