Modern water-heating technologies and efficiency strategies can offer energy savings in any household. With water heating consuming up to 20% of a household’s total energy usage, it’s a significant load. Here are more sustainable choices that can be offset by a PV or other renewably fueled system.

What I'd like to see is a heat pump that can be retrofitted to an existing water heater. Can't seem to find any mention of one though. [frown]

Thanks Sundug! Though I was hoping for something a bit more "plug & play". I've also wondered why a combination refrigerator/water heater isn't sold, or for that matter an air conditioner/water heater (though the heat pump water heaters do act as air conditioners). Installation hassles, I guess.

They do exist

I'm eyeballing the adapter that replaces the drain. Easy way to convert a water tank to a solar heated tank ....

I know they do, just haven't been able to find them.

I believe you can buy those adapters online. Or make one if you prefer. I'm not sure they're necessary though.
