The regular furnace in my 40x60 well insulated shop has been having temper tantrums lately-had a furnace guy out twice and he still can't firugre out what is wrong with it.
Anyhoo, I have been using a small propane bullet heater in there to help out. Should I be concerned about CO or CO2 build up in there? Anyone have any good or bad stories about this?
