Howdy,
I have an oil furnance in my basement, which is also where I want to place my woodshop. My concerns are not over blowing up the house. They are over the air quality of the rest of my home.
I have no problem turning off the furnance when I am in the shop, 'cause it's my home and mine alone! But what about dust particles being sent into the rest of my home where I won't be wearing a HEPA mask when the furnance is on.
Will the open flames of the oil burning make that a non issue? Frankly, I don't know how the internal parts of an oil burning furnance work other than the oil is sprayed out and set on fire. So, I don't know if the air passes through the flams thus litterally burning anything that would be in the air or if it passes through heated baffels or something.
Granted, I have a filter on the furnance, but I think that is on the intake side.
