Sure, although it did somewhat align with my real world experience moving from a new house to another similarly sized new house. All else equal, I saw my total energy bill increase drastically with the heat pump, even with an 8kW solar system. Something didn’t add up, maybe it’s not working properly. It raised a lot of questions for me. That said, it’s arguably really tough to compare these two heating systems objectively and you can’t take the advertised rating at face value necessarily. It’s not apples to apples. Electricity billing is complex and includes many more variables and gas is billed completely differently which adds to the comparison problem. Any comparison online ends up making many assumptions so of course we need to take that with a grain of salt.
