I live in a passive house (flatrockpassive.blogspot.ca). I burn wood in a walltherm boiler. I can assure you you will need make up air. This being said, there may be a fair share of complexities. In a super air tight house, a good "airtight" stove is a must. Wall thimbles also need to be considered as rarely they are made for thick walls and workarounds are necessary. Bringing a air supply close to the stove is not going to work. it needs to be attached directly to a closed combustion chamber. There are issues. you should be aware of. An HRV/ERV which is balanced in air flow doesn't necessarily mean balanced in pressure. In fact, if you balance an HRV, and then open a window, you change the envelope and it alters the balance. This becomes and issue whenever you open the door to a fire place in passive house. If the draft is not large enough, unbalancing the envelope by opening the wood stove door can back puff into the room. IT can be done safely though. It's mostly documented in my blog. Please have a look. you won't be sorry.
