The Grumman Sunstream CF100 Solar Hot Water heater I have is old, the
storage tank is rusting and the control box is on the frits to often..
I want to change to a storage tank that has a heat pump within it, but
no one makes this
Seems like the only thing to do is get another storage tank and also
get a tank-less water heater

I have tried to find manuals for the CF100, I think they have all been
recycled...

Any pointers of what could be done from someone out there

Or just sell the collectors, and upgrade?

How many watts do your collectors generate?

He collects BTUs not WATTs.

Ya, that's a screw up I did, should of been Thermal instead of
Photovoltaic
No Watts, system has a pump that feeds via house electricity
But would be nice to have the Solar Tube Water Panels feed via gravity

I have a two-panel system with the original controller which works fine. I used an 80 gal electric water heater for storage feeding into a 55 gal electric. Added an inkbird controller to use in the winter with my wood boiler using the potable water pump for circulation to a stainless heat exchanger. Panels are over twenty years old. Rebuilt one because of freezing water getting into a manifold while being stored. Easy rebuild. All copper and accessed the interior through the back, not the front! Every day this summer 162 degrees in tank email me if you want about THIS. Southernpiper1@gmail .com
