From the article:
Clean electricity nonprofit Rewiring America recently estimated a US household would save $1,800 per year if they installed electric heat pumps to heat their water and heat and cool their air, replaced a gas car with an EV, and installed solar.
I am only going to piss all over the electric heat pump water heater. I might piss all over everything else later.
First cost just to buy a 50 gallon unit base unit. $1800 for the heat pump type. $525 for natural gas, $450 for electric. Since I have only installed electric and gas units, I have no idea if a heat pump is more difficult or expensive to install, it definitely won't be easier or cheaper.
First heat pump water heaters do not heat the water near as quick as standard gas or electric models so they have back up 4500 watt heating elements like a standard electric. That 2-3 times cost savings is over a typical 4500 watt standard electric water heater, and that is on light use, heavy use will kick it into full electric heating element mode and save you nothing.
Once again, that is savings over a standard 4500 watt heating element water heater, not a gas one. Using electricity for heat is very
inefficient cost wise.
If you own a gas water heater, raise your hand. If you do a heat pump water heater will increase your utility bills, not lower them.
Once again we have a source pimping green energy not telling the whole story or flat out lying.
