This is not a separate heat pump add-on that you install on the water heater.
The heat pump is actually integrated with the unit. Cost is around $1500.

I don't know much about them, the little bit of research I have done has been
on geothermal heat pumps. The heat recoverable is relatively low, about 110F so
these are really pre-heaters. You can certainly save some money but the cost is
very high and unless you are using the heat pump equipment for other things
like heating or cooling the home so that the capital cost is expressed over
more intensive and varied applications it doesn't seem to me to be very
effective. The emersion heater is needed to raise the water temperature another
20 degrees all of the time and much more than that during heavy water use.
As a pre-heater though warming the water entering the tank with heat
generated from the air conditioning for example serves water heat savings as
well as improving the efficiency of the air conditioning.
The cost of a single purpose heat pump system must be relatively high, just
think of a small room air conditioner. It is very similar technology.

And what do they cost relative to a gas or electric unit?

Has anyone seen the hybrid water heaters? If so, what do you think of
them?
If you have one, how do you like it. For those who don't know, the hybrid
water heaters use a combination of a heat pump and electric elements to
heat
the water. This is supposed to result in significant savings, making it
cheaper to run than a natural gas unit.
