Can you clarify what you mean? There's only ~2 fans in my system, the one on the heat pump outside (looks like an AC unit) and the one in the air handler in the basement. To me sitting in my dining room this system is no different than any other forced air system.

He's saying that instead of a gas or electric hot water heater - you can now buy a heatpump version. It works the same as a normal heat pump, but it takes ambient air in your basement or garage or wherever, and then moves that heat into the water which provides a slight cooling and dehumidifying effect for your indoor climate. They make a lot of sense in the US South.

To be precise the heat pump water heaters are electric - they just use latent heat in the air around them as much as they can, but they'll fall back to electric when that isn't enough.

They also cease working when the power is off, of course.

The air for a hot water heat pump could be entirely indoor air, the entire unit is located inside.

Unlike an A/C which is split, with the compressor located outside.
