Thanks for that info. Being a southern boy, I knew only electric and natural gas for heating water.
We did, of course have fireplaces and wood burning stoves
in the house or shop buildings.
we have a wood burner in our house...here in Pennsylvania..we also have acreage and so we have a wood supply, have NEVER paid for wood..
our wood burner heats our house the entire winter...but just get tired of the mess and dust...but sure is nice to have a toasty warm house when the winds blow out the electric in the country!!!! we also have a propane gas furnace, so we don’t depend on the wood burner as much as we use to...hubby keeps our chimney cleaned, and we only use cured dried wood..thanks to obama and the cost of fuel, many folks depends on wood heat...
and with the cost of heating oil it is a great saving...many, many homes here heat with wood, coal...and many have out door furnace, the one disadvantage of those it you have to keep them burning 24/7 every day...all year long, year after year...ugh...some even burn their trash in them...that is becoming a problem...
Yep, it's a northern thing. Big out west, Montana, Idaho...etc.
