Hvac guy was over at the house fixing my boiler after I couldn't figure it out. And I was asking him what he would do if I wanted a coal wood stove to use the 1 chimney I have what would he do about the oil boiler and how to vent it. And he told be if I'd go with a new boiler that the new high efficiency oil boiler that they are direct vent now which with my current basement setup that would be a lot nicer then power venting my old boiler. My question is do they have these boilers down to pvc venting or do you still have to run a stainless vent. I was thinking about going with a budarus boiler.
