Oh come on Nathan...really? I thought the immersion was crazy enough but heating over a chimnea and picking up scraps of wood?
I'd love hot but not that much! If I ever want it that bad I think I'd just have to pay the going rate just as Dazmond has.
It's a project and who doesn't love a good project other than work and the mundane everyday day duties etc. Lol, picking up scraps of wood. I have customers who are tree surgeons and I'm sure I could come to some arrangement with them etc or yes, if I wanted to I could source plenty of scrap wood. But this isn't my project, just offering up ideas rather than being negative and thinking inside the box.
I do laugh how people tell me my own findings are wrong just because they can't achieve what I'm able to do, or didn't have the hindsight to get a larger tank and reserve water because they limited themselves to a 300 or 350ltr tank. Also what's up with a basic way of using immersion heaters for hot water rather than buying a fancy 5grand system with more possibilities of things going wrong down the line
