How much each change to the atmosphere has warmed the world:

The best part about my heat pump water heater is I have a massive "refrigerator" in my house. It keeps the room it's in about 45°F year round, which is great for storing wine and root vegetables, and storing beverages in there means they get cold in the fridge a lot faster.
Great for those on the south. Not as great for those of us that have to heat our homes, meaning a furnace or another heat pump needs to make up that heat.
Not that they are bad, mind you, they are quite good, just another part of the economic equation. Makes it more of a home run where you are cooling most of the year anyway.
My water heater is in an unheated basement closet, so technically most of the energy it's getting is geothermal since the walls are always at 50 degrees. It would probably be even more efficient if
Also, since the water heater is inside the house and is constantly leaking heat, it's not really cooling the house very much at all because the heat is still inside, just in an insulated bottle.
Mine is in my finished, heated basement (which is largely above street grade, so not too much geothermal). And while some heat does go back into the room, much of it goes down the drain when you use hot water.
