“Dont know, Ive been living here on Maui for 40 years. No need for heat in our houses.”
I hear you on that Fish Hawk, as we in Kea’au on the Big Island have not needed to even close the windows in our house ever, although up the road in Volcano they do use fireplaces and wood stoves. Wood stoves and or Fireplace inserts are far superior to just plain Fireplaces......where as stated correctly earlier 80% of the heat goes up the chimney.
Before moving here, we lived in the High Sierra Nevada mountains where we had minus 42 degrees for three straight days in 1972. Our wood stove kept us warm and when the electricity went off the stove top was put to good use making soups, stews and other creations.
To Sun. No question about it...go wood stove insert for the fireplace, or look into the newest efficient kerosene stoves.
Same over here. Up country like Makawao, Pukalani, and especially the Kula area, most homes up there have some sort of heat. I live in Kihei close to the ocean and no heaters needed any where around here. We got Whales here now, seen any over that way? The Humpbacks are here for the winter.
