That massive spike of 50c/kWh at the left looks tiny compared to today even though that’s already insanely expensive

    In colder areas like that the heat pumps are usually ground source so the ambient air temperature doesn’t change the performance much.

      Have you actually priced such systems and the payback time vs heat pumps vs petroleum sourced heat?

      I know one person who chose a mix of ground heat pump, LP, and wood heat. He told me that it only had a reasonable payback was because he was building a new home and the extra cost could be tagged to the total build cost. Making it cheaper than a retro fit. He said it added another $25,000 to the cost of his new home. But in fairness, he does enjoy it.
