I had thought about EVT CONVERSION myself . Would clearly prefer a conversion option, which means you have the "forever" option of any standard tank.. ie .. I bet a EVT tank is more expensive :| .... got you bytha ....

That's what I am thinking about, being able to retrofit EVT to a plain resistive tank or even to a faulty heat pump tank.

Particulary with our long term plan of converting completely offgrid after we move.

Heat pump hot water still sucks up electricity, and as I understand it on the cooler days it really has to work a lot harder, and offgrid I think that might be a bit of an issue.
