Adding an exterior air source

Masonry Heater Design
1

I’m new to masonry stove design. My wife and I are building a Passive Off-grid home just outside North Bay, On (4 hrs north of Toronto) on 8 acres. The home will be well insulated and very tight meaning the stove must draw air from outside the building. A hot water buffer tank heated by solar, propane and the wood stove is used to heat our domestic hot water and for rad heating.

What I’m looking for is a small masonry cook stove with the following;

  • can accommodate an exterior air source
  • can accommodate piping for heating water in the buffer tank
  • firebox door with a viewing window
  • oven

I’ve looked at the Walker stove but the design doesn’t appear to allow for an exterior air source.
Any suggestion would be appreciated.
