How much BTU/H does a wood stove use?
For starters, a wood stove usually has a rated output that is way more than any Passivhaus can use. A 55,000 Btu/ h stove in a house with a 7,000 Btu/h load is just overkill. Secondly, most wood stove installations introduce air-sealing problems that make it hard to get a home’s airtightness down to 0.6 ach50.
What thickness plywood should I use for duct ducting?
Once the duct was properly sealed, I needed to add a piece of 3/4-inch plywood to make the plane of the PVC plate flush with the plane of the siding. The plywood has the same thickness as the strapping.
Is a wood stove a thermal bridge?
They are huge thermal bridges (especially if they are on the outside of the house like mine is); they are hard to air seal; and most wood stoves are atmospherically vented. This means that the air that the wood stove uses for combustion comes from the room it is sitting in.
Can you air seal a chimney?
Chimneys are difficult to air seal. If you are installing the type of wood stove that is designed to fit in an existing fireplace, you have a big hole just above the insert area up into the flue. At my house there was now also a hole at the back of the chimney to bring in fresh air.

Why are closed combustion fireplaces more efficient than open fireplaces?
Most models feature a sealed chamber where the fire burns behind glass doors and adjustable air vents to regulate the oxygen supply. Since the air intake is limited to only the amount needed to keep the fire going, the burn is more efficient and there is far less heat lost up the chimney.
How does crisscrossing affect the burn time of logs?
The configuration of logs also affects how quickly the wood will burn. Crisscrossing the wood "log cabin" style is less efficient and will make the logs burn faster because it creates a chimney effect. One way to achieve a longer burn time is to build a top-down fire like the one below:
How much does a cord of wood cost?
The average cost for a cord of wood varies depending on the species and quality of the wood, the time of year, and where you live.
