Why Do All Outdoor Wood Boilers Require Filters?

Why Do All Outdoor Wood Boilers Require Filters?

"Filter Kit - Why Needed for ALL Outdoor Wood Boilers" 

Sediment Build-up on Outdoor Furnace Water Jacket

The "Secret Killer" of all outdoor wood furnaces is sediment. It will eat through steel, AND cause electrolysis damage to your water jacket - holes in your boiler are very bad.

We know that we have been recommending the use of our Liquid Armor Water Treatment and sending us water samples to ensure that your water is properly treated, however, just using chemical treatment is not enough to keep your outdoor wood burning boiler free from sediment.

How Important Using a Filter Is For My Outdoor Wood Stove?

We get calls from outdoor wood burner owners who need to replace all their pumps and heat exchangers which are more costly than just having a filter. This could have been prevented if they had a filter, or just replaced their cartridge faithfully every 4-5 years.

If you are not using a filter it's not yet too late to do so because you can still install one now easily. This will reverse the damage being caused by sediment, and clean up your system perfectly!

Is There A Need For Me To Replace The Filter Cartridge?

Yes! Most outdoor boiler owners already have a filter. But many do not realize that the filter CARTRIDGE must be replaced every 4-5 years. This is an important part that many people are not familiar with. 

If you don't replace your cartridge, sediment will begin to pass between the seals and edges of your filter, causing the steel to thin and lose its efficacy.  As a result, the benefit of having a filter is lost. Click HERE to discover more about the advantages of using a filter.

If you have had your filter longer than 4-5 years, but have not replaced the stainless steel cartridge, we strongly recommend that you replace this cartridge immediately - they are available HERE.

Filter Kit Assembly

There are Filter kits available that come with the drawing and instructions that we have prepared for you! They include literally every component needed to put a filter together, 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 order of the Filter Kit. If you have any questions about the filter kit you can Click HERE for more information.
