Tankless Water Heaters vs. Storage Tank Water Heaters - Consumer Reports
"If you depend on electricity to heat your water, you have another choice that’s better than a conventional tank or a tankless water heater. And that’s an electric heat pump. It has a holding tank like a conventional water heater, but sitting atop the tank is a heat pump that captures warm air and transmits it to the water—sort of like a refrigerator working in reverse. Basically the heat pump is moving heat from one place to another rather than generating heat itself. That’s why it’s so energy efficient. “Heat pumps also have heating elements like conventional water heaters that turn on if the unit can’t generate enough hot water on its own,” says Banta."
