Two Appliances One Chimney

Short story is I don't want to use my oil furnace. I have changed my tankless DHW over to an electric energy smart tank. Our US Stove 2000 does the majority of our 2100sq ft home to 60-62 and struggles in the deep cold.

I love the stove so much I'm thinking of adding a second in the home. My large kitchen has a the brick chimney and a flue blockoff cap that is in the chimney for the oil boiler. If the oil boiler is turned off would it be considered acceptable to then use the chimney for a wood stove. I would line this chimney as well. An ole'timer stopped and said the previous owners heated for years with a wood stove in the kitchen.

I've heard some states have now passed laws saying you can once again run dual fuel appliances into one chimney.

The US Stove was given to us so we installed it as an insert kinda stove into a real small fireplace opening. I have not looked into a bigger stove yet as another option but do know that air movement can be difficult the with the layout of the home. I installed it as supplemental heat and realize how much we save burning wood. The oil burner never kicks on. It heats the small living room, dining room, and I cut a return to the upstairs and the heat rises circulating the cold air down stairs. The output of this stove is pretty amazing to be honest even if undersized for my application. My thought is two of these burning will do what we need.

I will look at the englander as well.

remove the boiler or disconnect the vent piping? I'm in the hill town's I know all of this has to be inspected but when I had the install inspected it was to check my clearances only.....kind of a joke if you ask me. He didn't care about the liner, the block-off plate of any of that. He was out in 2 min.....

Talked to our fire chief and he said "nope all goes thru the building inspector"

I read all this safety stuff here, how paranoid everyone is about everything, and the inspector seams to care less grrrrrrrrrr
