What is the cheapest way to heat an insulated garage/barn that has no built in heating system? Propane? How bout a wood burning stove? We have gas in the house that is super super efficient but nothing in the barn that we want to convert into an office. I am not sure how complicated it would be to put a pipe out to the barn to heat it with the gas system we currently have.
The barn is about 25 feet from the house. It is a 2 car garage actually with an extra small room on the side.
Thank you in advance. I may not reply to all comments but I am very grateful for any advice.
