Frequently Asked Questions
How far away from my house can the boiler be placed?
Most experts recommend keeping the unit within 50 to 100 feet of your home. Any further increases the risk of heat loss in the underground lines, regardless of how well they are insulated.
Do these units require a lot of maintenance?
You should plan to remove ash once a week during the coldest months. Additionally, you must check the water chemistry periodically to prevent scale buildup or corrosion inside the system.
Can I use an outdoor wood boiler to heat my domestic water?
Yes, most models include an internal heat exchanger specifically for domestic hot water. This setup allows the boiler to handle your showers and laundry, often eliminating the need for a separate water heater.
What happens if the power goes out?
These boilers rely on electricity to run the pumps that circulate hot water to your home. You need a reliable backup generator or an uninterruptible power supply to prevent the system from freezing during a winter outage.
Will the smoke bother my neighbors?
Modern EPA-certified models burn wood much more completely than older designs. This results in significantly less visible smoke, but you should still position the unit downwind from nearby homes to maintain good relationships.
