Electricity monopoly in the US = they can price gouge, and this is literally the only reason I installed a dual fuel system with a less efficient heat pump. The Eversource electricity price hikes last year probably would have meant I couldn't afford to heat my home in the worst parts of winter here in Massachusetts.
This is how policies are killing the planet. Socialize electric utilities, upgrade the electric grid, subsidize the use of electric heat pumps so they're actually affordable for all end users, and of course more people would adopt them.
As it is, I run my heat pump as much as I can, which is like 9 months a year. Better than only having gas heat at least.
The US has some of the lowest electricity prices in the world though. Only a couple pennies per kWh higher than Canada. And MUCH lower than pretty much all of Europe.
In 2020 (last year I could find from Canada specifically) Canada averaged 11.25¢ per kWh. The US averaged 13.04¢. The UK averaged 21.91¢, France averaged 19.91¢, Finland 20.56¢, Spain 28.77¢, and Germany 33.39¢.

It’s more that Canada uses a LOT of hydro power which is cheap.
This is the problem I'm facing though:

Our electric rates went from 18¢ to 25¢ last winter with no warning. It's not that our prices are particularly high for now, but rather that they're unreliable. I didn't feel secure installing an electric only system because of this, even though I could have gotten a more efficient system. The dual fuel allows me to toggle between the two as needed, which feels like the safer option for the next 15-30 years that I expect to have this thing.
Sucks because I'd really prefer to have one of those Mitsubishi hyperheat systems. But even with the less efficient system, I'm running in heat pump only mode in the to 0⁰C nights we're seeing right now and it's fine.
You made the most sensible choice and are dramatically reducing you gas use, so you should feel good about that! I have a new Mitsu hyper heat (Colorado here), but recognize it wasn't the most cost effective system and ultimately just really wanted it. It's bonkers how well it work though. We've only hit 10F this last weekend but it didn't skip a beat. Looking forward to -10F. For most people, keeping a gas furnace for a few weeks a year, and using a smaller heat pump than you would spec if only using a HP makes a lot of sense. You're not missing much (and some would argue that peak winter demand in an electrifying world is a big problem that has backup gives us more time to solve anyway).
Yeah, you did exactly what I wanted to do haha. I just love the Mitsu products so much. I had Mitsu mini-splits when I lived down in the Caribbean, and I'm a complete convert. I did install a supplemental Mitsu mini-split in the largest room in my house, which actually is so god damned efficient, it reduces the load on the central heat pump. The two combined get me through a really reasonable portion of the year. Those things are just amazing.
