My A7 AirTap has been running almost 5 years now. But, my tank is also heated by some solar PV, which is a nice assist.

Had some problems with frost and with the iron nipple on the cold water input.
We also lost one of the 200W panels. Only 3 left, 600w max.
But, the system is still providing enough hot water for two old folks..
It helps keep the basement dry too.

Now that it's still too cold to use the big dehumidifier, we have to rely on the A7.

I was gifted an old broken A7, so I might have to try your out-board HX idea..

Cheers,
Rich
