Sound level is less than 50db about the same level as an older refrigerator, newer refrigerators are quieter. The evaporator is part of the water heater and is either side or up discharge depending on the brand. They do have a washable plastic filter that should be cleaned yearly or bi-annually. We have to look at each job to make sure that it can fit where the old water heater was installed. Sometimes we can't make it work and the customer is stuck using a gas water heater or a tankless that takes up less space.
A heat pump water heater uses a compressor and coil to extract heat out of the air and put into the water. Same principal as your air conditioner removing heat out of the air in the home and then rejecting that heat to the outside air at the condenser. The principle is the same as used on a water fountain, except in reverse. Where a heat pump shines is the efficiency it has compared to standard gas water heaters or an electric element water heater. The real trick is calculating cost between different sources of energy ie; natural gas vs kilowatt per hour. Because one is sold by the therm and the other by the kilowatt you have to figure how much it costs to make produce a million btu's with each and then compare as I did using the chart in the video.
How noisy are they? And where does the evaporator discharge to, I'm assuming into the house?
Answered one of my questions. It would add heat load to a house in the winter.

If inside the house, yes slightly.
What’s the difference between a heat pump water heater vs all electric?

It costs 4x as much.
No for us 3 times as much. That is why I wouldn't do it without the incentives.@@badawesome3047
