The tech costs more than conventional options upfront, but federal tax credits, new 120V models and strong savings have made them more appealing than ever.
Its a state that is north and was used as an example for a place that is much colder than southern states that you claimed would only make sense for heat pump water heaters to be sensible in.
Where did I supposedly make that claim?
I’ll give you a hint: I didn’t. All my references to northern climates were only to demonstrate that water heaters in northern climates are indoors, within the heated space of the northern home.
I never claimed that heat pump water heaters were not sensible for northern climates. My claim was that they were not sensible for winter use in gas-heated homes.
Logically speaking there is not downside to having a heat pump water heater next to the gas furnace.
Yes, there absolutely is. The heat inside a gas-heated space is produced from burning gas. Pump heat out of that space and into water, and the temperature of the space drops. To get the temperature back up, you need to put more heat into the space. Again, the source for that heat is gas.
You’re burning gas to produce heat, then pumping that heat into the water. You can make this process more efficient by moving the flames closer to the water. Get them close enough, and the flames can heat the water directly, without needing the pump.
Look, a heat pump water heater does not generate its own heat. It takes heat from a space, and puts it into water. Where the heat got into that space by gas, the water is heated with gas. Where that heat got into that space by solar, the water is heated by solar. Where the heat got into that space by robot ninjas, the water is heated by robot ninjas. The heat pump merely takes the gas-heat, wood-heat, or ninja-heat, out of the living space, and into the water. To maintain the temperature of the living space, you need to add heat: gas heat, wood heat, ninja-heat, whatever.
If the source of the heat around the water heater is provided by gas, you would be better off burning the gas inside the water heater, where it doesn’t need a “pump” to push it into the water.
Another way to look at it: Furnaces located inside insulated structures, like northern furnaces located in basements, do not produce “waste” heat. The heat that doesn’t come from the ducts still goes into the house.
Yet another way to look at it: would it make sense to install a traditional heat pump to draw heat out of the insulated, gas-heated, northern basement and push it into the living room?
Then for anyone making the switch, they should get the heat pump powered equipment when they can, be it if the water heater is replaced before the hvac unit or vice versa
False. To see any winter gains, the HVAC system must be switched first. All of the gains of the heat pump come from the “free” heat drawn in from the atmosphere. Until the heat pump HVAC system is installed, your heat pump water heater is a particularly inefficient gas water heater all winter long, more than erasing any gains you will achieve during the summer.

So much anger. Have a good day, I cannot read your post intellectually anymore and will not participate
