Very smart, we've spoken about doing something similar, just waiting on time and finances to come together. :D I wonder if the long burning candle idea would work here after we've finally got it in place, it can get into the mid -30's C or lower here some times, thankfully not for long periods normally though.
Thanks for taking the time to answer my questions. :D
God bless you and your wonderful family. :D Have an awesome day my fabulous friend! :D
