Frequently Asked Questions
How often will I actually need to add wood to the furnace?
Most users find that once every 12 to 24 hours is sufficient during typical winter weather. If you have an oversized firebox and high-quality seasoned wood, you can often push that interval even further.
Can I heat my domestic water with an outdoor furnace?
Yes, most models include a heat exchanger specifically designed to supply your home with hot water. This addition removes the load from your indoor water heater, which significantly lowers your monthly electric or gas utility bills.
Is it okay to burn green or damp wood?
You should avoid damp wood at all costs. It forces the furnace to spend energy boiling off moisture rather than heating your home, which leads to creosote buildup and poor performance. Always stick to seasoned wood that has been split and dried for at least six months.
Do these furnaces require a lot of maintenance?
Daily maintenance is usually limited to clearing out ash and reloading logs. You should perform a thorough cleaning of the heat exchanger tubes and check the water chemistry once a season to prevent internal corrosion.
Will this system work if the power goes out?
Your furnace requires electricity to run the blower fans and the pumps that circulate hot water. You should keep a small generator or a battery backup system on hand to keep the water moving if the grid fails. Without this circulation, the water inside the jacket could overheat or freeze depending on the outside conditions.
