My son has the 80 gallon version. Saves a bunch of money. Drops the basement temperature noticeably. One year in thermistor had to be replaced. The company sent him the parts with instructions. Run noise not to loud.

My issue is this. For the cost of the HPWH I can buy 3 electric WH. I average 8-10 year life span with our slightly hard water. So does it save enough electricity to pay for another one in 9 years?

If you are against EV subsidies you should be against HPWH subsidies.
There are or were great incentives to purchase HPWH water heaters.
When I purchased mine I got a $700 instant rebate from my state and got a $300 Federal income tax credit.

I purchased mine because the total cost after purchasing some wire, a breaker, and some pipe and fittings, it cost me about $500 out of pocket.

I can testify that my heater hardly uses any electricity and supplies plenty of hot water for my household needs. I have never run it on any mode except for heat pump mode.

I would buy another one tomorrow if the incentives were still there.

Even without incentives, they are extremely energy efficient so they would probably be worth the price because of energy savings. If I am not mistaken all water heaters are expensive these days.

Gets me thinking that when you insulate your house and they have no sales tax on insulation or tax rebates or incentives to insulate you should not take advantage of those either if you are against tax incentives for energy savings or green new concepts.

How large is his basement? Noticably being 2-3° or more like 10°? Where mine would be located any sound would not be an issue.

So after all tax credit etc, only cost $500. That's what a regular WH Costs. So all the electric saved alone should pay for another one in 8 years if subsidies are dropped, correct?

I think they pay for themselves in pretty much no time. I don't see any energy usage from heating water. I monitor my energy 24 hours a day.

Depends on your cost of electricity. In my area the ROI is long, in some areas it is 2-3 years.

Do you ever check/change the anode rod?

No. Of the last 3 I have changed, one had element issues, kept burning out lower, the other 2 rotted out. We get some lime buildup. Weird thing is life span didn't change wether we had softener or not.

Can't give you exact numbers but the WH is in a large room and the temp. probably dropped 5 degrees. I read the 4 star reviews for this model. People like them. I think it was the 5th review in particular that was very informative. The guy gave some good insight. Can't say for sure but I suspect these tanks are of a better quality than regular heater's tanks.

The one I was actually interested in I found in a Bob Villa article. It was German made. Problem is they didn't vet the fact that there are no distributors in the US. The one I linked to was first on the list. I think I would have to run it in regular heating mode in the winter, 5° would probably keep basement less than desirable temperatures.

I bought 2 of the 80 gallon size... Mine are A O Smith models...

That were on closeout at Lowes so I picked up 2 one the

older model and the other the current model...

They aren't going to stock the 80 gallon models...COP of 4.00...

I also bought the extended warranty to protect my investment...

I also have a GE Geospring HPWH with a COP of 3.50...

NYS gives a $700.00 rebate and you can self install...And the federal tax credit...

Total of $1000.00 off each if you are entitled to both rebates...

I use the older GE for DHW and the others for space heating...

We use less than 2 Kwhr per day at off peak rates about $3.00/month...

We are only a 2 person household...About 10 cents a day...

I am against subsidies.
I think they should all be eliminated.
If subsidies are available and I do not use them for purchases I make, I would be a fool.
