Off-Grid in Australia - Yes it does get kinda cold.
Hi from Australia,
Down here we don't have nearly the heating challenge of our northern hemisphere friends, but in my zone we run from -8degC to 43degC over the year, have a genuine four seasons and heat for about 4-6 months depending on the year, typically wood heaters for rural situations. I'm working on a rural house design for our farm and considering an integrated heating system which would primarily use wood for heat in winter and solar for DHW in summer. The backup would be LPG (propane). I've attached the P&ID concept and would appreciate a critique or recommendations from others experience.
Thanks in advance.
