Honestly? No. I've build a new home and do heat with heat pumps both the home and sanitary water, it's efficient and effective. In the old home there is only minisplit aircon and classic gas heating. Why? Simply because we can't go all, all-electric at the power level needed in classical homes. Yes, heat pumps are effective, but if you are not in a relatively hot climate heating a classic badly insulated home with electricity still means too much power. We can do for some, we can't for all. My current home with -18/-25℃ (-0.4/-13℉) absorb 6kW/8kW electricity, and that's enough to have 20℃ inside. The old home in a much mild climate use 24kW thermal methane gas. Here a classic home converted to a air/water heat pump would consume around 12-15kW, only a geothermal one can consume less. It's not sustainable if we ALL do that + cars recharging and so on. The simple truth is that: if local climate do not go much beyond 4℃/39℉ we can convert also old buildings, as long as in the summer we do not need much to cool during the night, otherwise we need new homes. This is the very same issue with the new deal at all: it's perfectly feasible in new buildings, it's not in classic ones. We can "upgrade" a bit anything, but only a bit.
