Why Should I Have A Filter for My Outdoor Wood Furnace?
No Filter In Your Outdoor Boiler System?
This is YOUR Water Jacket
Sediment is the "Secret Killer" of an outdoor wood burning boiler. It will eat through steel, AND cause electrolysis damage to your water jacket - holes in your boiler are very bad.
Most outdoor furnace owners already have a filter. But some dealers make the mistake of NOT recommending a filter to "get the sale". This is not wise.
If you don't have a filter, this is not your fault of course if your dealer did not even tell you about it. But you still need one to protect your system. Learn more by clicking HERE.
We get calls from outdoor wood stove owners whose systems are from 3 to 7 years old who need to replace all their boiler pumps and heat exchangers at great cost because they became plugged and destroyed by sediment damage. This could have been prevented if they had a filter.
If you don't have a filter, you can install one now easily. This will reverse the damage being caused by sediment, and clean up your system very nicely!
Filter kits are also available! They include literally every component needed to install a filter, including the bypass. A bypass is required to allow the water to continue flowing while the filter is getting cleaned every month or two. 
Simple instructions and drawing for the filter are included with every Filter Kit. Click HERE for more info on Filter Kits.
A filter will enable you to Turn UP Your Thermostat and Still SAVE Money on your heating bills for decades with your outdoor wood burner!

Operating Furnace FAQs:
- Am I burning too much wood?
You may be. Is the wood properly seasoned? Have you cleared the firebox? High wood consumption can be caused by a number of factors.
- Can I leave my Outdoor Wood Burner over the weekend?
You may have someone "feed" your furnace for you or you may lower the thermostat temperature.
- Should I turn my thermostat down at night?
No, the lower the water temperature will cause the use of more wood to recover.
- What are the critical items to operate and maintain my furnace efficiently?
1. Keep water full
2. Manage ash
3. Use water treatment
4. Use seasoned wood
5. Keep fire in the middle of the firebox
6. Clean tubes regularly
Maintenance FAQs
- Why is outdoor boiler water treatment important?
The boiler chemical (corrosion inhibitor) that you would apply to your furnace water coats the inside of the furnace to reduce the effects of corrosion on the metal.

- How often do I need to Inspect my Chimney/Flue
Inspect chimney and flue monthly and clean as needed. Clean chimney and flue annually. Perform cleaning and maintenance only when no fire is present in the firebox and ashes are cooled completely.
- Why is ash management important?
If the ash becomes wet it is corrosive to the metal of the furnace. If the level of ash is too thick in the water box it does not allow for efficient heat transfer to the water in the water jacket of the furnace. The temperature of the water in the jacket is used to heat your house.
Troubleshooting
- Why am I not getting hot water?
Check that the hot water system is connected properly. Check if the heat exchanger is partially or totally clogged.
- Why does my furnace continue to burn when it is not operating?
Check the door seal, door adjustment, and solenoid.
- I can't find a leak in my furnace. Why am I losing water?
Outdoor Wood Burning Boilers use a non-pressurized system, this means that the existing heating system is exposed to the air. Since the water in the system can and will be warmer than the air, there will be evaporation of the water in the system. The water must be checked and adjusted at least once a month, sometimes more.
