Maths: 85% discount on fancy new waterheater, which also dehumidifies and cools your house (passive result of heatpump).
TVA usually offers this promotion between Thanksgiving and NYE. You can order online from HomeDepot, or walk into a local store [0]. This ends up costing LESS than a new traditional resistive-type heater.
[0] either method: they DO verify SFH (by more than just ZIP code) -- duplexes and contractors not authorized/allowed

My own $250.00 "TVA homeowner special" (as a licensed electrician):
<https://i.imgur.com/4wCez9u.jpeg> this specific design draws from both bath and bedroom [dual 6" inlets], exhausts into kitchen [single 8" outlet] | utility closet is only 5ft x 4ft (~20sqft)
Don't forget to use a pressure regulator, expansion tank (coldside, only), & (preferably) a sediment filter. Whatever you do: do NOT use a water softener before the tank.
People almost never go back. This isn't just a temporary improvement.
- No outdoor unit that looks awful in many settings
- works well, even in the coldest winter, without a spike in electricity usage, COP 5
- very reliable with long durability
- super quiet, no ambient noise
- 20% more efficient
Currently, drilling is very disruptive in retrofits, but there is progress in compact techniques that might change the equation.

If you get one, just make sure to get the dimensioning right. They are WAY more complex to plan, install and maintain than traditional heating.
This a no-brainer for buildings with high energy use. But we looked into getting a heat pump last year but it doesn't pan out because our house (15 years old) has a very low energy use and we would not recover the costs (about 20K euros after subsidies) for 20+ years.
Not a big increase on a relatively small base. What is the takeaway here?
As a renter, I have no incentives to invest thousands in my home's betterment because I will have lost those when I am gone. As an owner, I have no incentives to make my apartment/house better because I don't live in it and I don't pay the energy bills.
Something has to be done about that if we want to combat climate change. I know in France it is now forbidden to rent again or sale when the renter leaves if the home's energy grade is F or G (A is best) but it is probably loosely enforced/easy to circumvent. And it is too damn slow ! This is for regulation but maybe there are other levers ?
As a renter I would basically have to wait for energy prices to skyrocket for it to make economic sense. I hate this situation.
It’s not just heating anymore, now places need active cooling too.
Covid was the wakeup call that globalization was dying a slow death, and the first trump that world cop America was also on the way out.
Oil dependence in a top level national security concern of the last 150 years (hey, what really triggered WW1?), yet the primary means for independence has been politically suppressed for 50 years.
How soon would we have has better PV, better batteries, better heat pumps with proper subsidies and research starting with the 70s oil shocks?
while they purposely end climate-change research including destroying billions in observation satellites by deorbiting them
the history written about this decade is going to be wild, if we survive it

End users could have simple resistive heating.
But no, in the name of invitation and net zero, end user are forced to bear the cost and maintenance burden of much more complicated equipment systems.
It’s all arse-backwards.
