Filter Products

The Outdoor Boiler Filter Kit products are the components needed to protect an outdoor wood boiler system from failure due to sediment build up using a high temperature-tolerant filtration system.

Why Boilers Need A Filter

Sediment is the "Secret Killer" of outdoor boilers. It will eat through steel, AND cause electrolysis damage to your water jacket - holes in your boiler are very bad.

Most outdoor boiler 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 boiler owners whose systems are from 3 to 7 years old who need to replace all their heat exchangers at great cost. 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 perfectly!

Filter kits are 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.

A filter will enable you to Turn UP Your Thermostat and Still SAVE Money on your heating bills for decades with your outdoor wood boiler!
