Here’s a little more incentive to check it Mick………..thanks to all the “sky’s falling, planet’s cooking, ice is melting” panick merchant tree huggers, you can’t (or soon want be able to) buy the old style element type system!!!!! You’ll have to replace it with a ‘heat pump’ type unit which costs mega bucks (not the $1000 or so)

I think its all a plan to get you to spend your hard earned dollars.
Most of the the “green” solar hot water heaters still have a separate tank with a standby heater element in it for when the sun fails to shine. A lot of the tanks for these systems are stainless instead of copper or glass lined but still have a limited life?? So I think the old HWS tanks as we know them will still be available for old installations etc where it is just not practicle for clean green energy. Oh, sorry, but these Greeny F*** W***’s are not practical so who knows what will happen in the future 
My thoughts and I have been known to be wrong before :laugh:
