My A7 is
still making hot water. I guess having the PV panels is helping to extend it's life span.
My free A7 is being stored as a source for spare parts. I also have the spare thermostat control unit NIB..
It looks like a bear to change out.
I was thinking of adding on an HX and preheat my oil burner boiler, but it has too much heat loss.
If I did decide to pre-heat that old boiler, I would install some standard 13 ohm hotwater tank heaters and hook them up to some PV panels..
No moving parts might last a long time..
