Only problem with the meat thermometer (or a more sealable thermocouple) I now realise is that there's nowhere to insert it properly. Now that I know what I thought was the mains water inlet is actually a sensor well (not sure why it has to have mains water around the sensor, as well as the sensor apparently going into the tank), one thing is cleared up. That is, I couldn't see why a sensor probe wouldn't just obstruct the water flow at the inlet. Of course it would, and that's not what the manufacturers did. So I won't put in a sensor in the solar hot water inlet, because that would obstruct flow.
So Hills manufactured a tank that could never have a thermometer attached. Well, that probably saved them 20 cents per tank, and -- lessee now -- would have returned the shareholders or Hills Family or private equity firm or whoever another 0.0000001% profit. Gee, free market thinking always works.
So unless someone's gone through the exercise of tapping into the controller for a readout (seems not) then I will just explore the idea above of a surface sensor on the inlet/outlet as per Greg's suggestion.
