hmmm?
Do you use the oil in the summer for HW?
The first question I got answered from AHS was that the WOC was not as eff at burning coal as to the Coal Gun
and the wood not as eff as the Wood Gun.
Ben from AHS told be since they (WOC) are meant to burn both W and C, that their specs are broader and not as eff.
Since that was my first question, I jumped back from the WOC at that particular second.
Now if you burn oil in the summer, then it is understandable...but adding an oil burner is about $1300 on the WOC
and about $1500 on the Coal gun. $1900 i think if you want auto switch.
Did you buy used or get it on sale?
What made you choose the WOC to the Coal gun, if you are only using coal?
Just helping make my decisions, not trying to call you out...
Also what type of heat?
I have stand up cast iron radiators

I didn't have any seasoned wood, so i got 2 ton of coal and will never burn wood again,since coal is easy and less work,less mess,less expense.
easy for me to say
