Any type of stove uses inside air for combustion and creates negative pressure in the home where outside air will seep in.
Passive house principle requires airtight home and heat recovery ventilator to heat the incoming air with outgoing air.
Rocket stove mass heater exhaust temp is low enough to try to use it with heat recovery ventilator to use the remaining heat to warm the incoming air so cold air doesn't have to seep in.
Did anyone try this idea?
