I am Guessing you mean 300,000 BTU and Not 300. I am in Chicago and have places with 2 of these 300,000 BTU heaters and they do the trick until about -10 degrees depending on wind (Not wind chill)
Thank you Earl! I did mean 300K.
Just trying to make sure I have enough punch for the winter. With the narrow bay it will be difficult if not impossible to place a torpedo heater anywhere if addition heat is needed. May have to hang one or build a some sort of shelf.
