I recently installed an Emporia Vue with monitoring for the individual circuit my water heater is on. It captured the very significant difference in energy usage from replacing resistive heat with heat pump.

Enjoy your savings! These are wonderful!

I bought my first heat pump water heater in 2007 (GE Geospring) and was sold on the technology ever since. When I moved to a new house I put that upgrade on the shortlist and now have one in this house too. There isn't much savings in winter (as I don't exhaust it to the outside air), but for the other 9 months of the year the savings are significant!

I'll have to watch how it changes in the winter.

I have a State, and actually the resistance heating is the 1st unit after the heat pump failed; then I got it replaced under (parts-but-not-labor) warrantee. So I'm a big fan of the technology but not the brand. However, the new State does have duct connections, maybe it'd be worth hooking those up. You like the Geospring?

I did like my Geospring, but GE sold the entire division off to another company some years ago. Since then I can't speak to the units. My new one is a Rheem. I got it fairly inexpensively from Home Depot and have been happy with the performance of it thus far.

One word of warning for the Rheem units. They make two lines and they DO NOT call out this major difference between them.

Professional Prestige - This line is sold through professional plumbing supply houses. These use slightly higher quality parts, and more importantly, include warranty on parts and labor and they can be repaired in place. There's no way around it, but these are more expensive to buy. When I got quoted me it was over $1200 more expensive to go with this line's model.
Professional Platinum The other line is sold at retail to big box stores (like Home Depot). These include some cut corners and sometimes cheaper parts. While the warranty length is decent on these, they offer WHOLE UNIT REPLACEMENT ONLY. Meaning to get the warranty honored, you're required to disconnect the unit in your house, take it back to a retail store, get a replacement unit, and reinstall the replacement unit. I suppose if you're handy, have a truck and tools, this probably isn't a big deal. I personally don't have those things and if I ever need a warranty replacement I'll have to pay for all this labor and delivery out of pocket.

If you want full service and support options or go cheap for savings will be up to you.
