Cleanfire® Wood Bricks – Efficient Wood Stove Heating

Firewood - Cordwood Alternative

The new cordwood alternative fuel for wood stoves is here.  Wood Bricks by Cleanfire burn hotter, cleaner, and longer than the equivalent amount of firewood without using any accelerants. Cleanfire Wood Bricks will make heating with wood much much easier and cleaner.

What makes Cleanfire Wood Bricks better than cordwood?

Made of kiln-dried, super-condensed recycled wood chips and sawdust, these bricks produce cleaner-burning, longer-lasting heat than cord wood alone. The biggest reason for the better performance of our Wood Bricks is the low-moisture content. Unlike cordwood, Cleanfire Wood Bricks do not lose heat evaporating the water trapped in the wood fiber. Instead, more heat is made available to warm your home.

Why should I switch from Cordwood to Wood Bricks?

Cleanfire Wood Bricks

Convenience: Cordwood requires too much work. Typically, cords of wood are dumped on your lawn or driveway. Then the moving, stacking (and sometimes splitting) follows. Even more time and effort is added if you have to season your logs before use.

Cleanfire Wood Bricks on the other hand come packaged in shrink-wrapped bundles (15 bricks per bundle), on a one-ton pallet. You may store them right on the pallet, or move these stackable bundles inside your garage or basement.

Cleanliness: Not only are biomass bricks environmentally clean, but also clean for your home. Unlike cordwood, which can have up to 20% bark, high levels of mold, and unwanted insects; Cleanfire Wood Bricks are bark-free, mold-free, and bug-free. Wood chips and sawdust are the only components in the kiln-fired bricks, which means there is no chance for insects to make homes in them.

Consistency: Even with the more expensive kiln-dried or pre-seasoned cord wood, burn time and heat output can vary due to size and wood type/age inconsistencies. Compressed wood bricks are dried and pressed in a mold, making a uniform shape that has consistent burn times. Cordwood has many variables (seasoned vs. non-seasoned, wood type, size, kiln-dried vs non-kiln-dried, etc.) so the BTU level can be unreliable. Furthermore, in order to burn properly, wood should be between 15 and 20 percent moisture. To achieve this level of moisture, at least a summer of proper storage will be needed to dry out.

Cleanfire Wood Bricks burn at up to 8000 BTU/lb – much more efficient than air dried cord wood which typically burns at 6500 BTU/lb. Also, the bricks are dried to less than 10% moisture before they are packaged and delivered!

Efficiency: Wood bricks are manufactured to release as much heat as possible when they burn. When anything burns, the energy is released as heat and light. Compared to cordwood, bricks release much more of their energy as heat vs. light, maximizing the BTU’s being generated per pound. Cord wood will sometimes generate larger and brighter visible flames, but the energy used to make those bright flames is wasted when it comes to heating. Many first time customers are surprised at just how much heat will be coming off a burning brick when they are used to seeing the larger flames that cord wood generates.

    Can they be used in a regular fireplace or do I have to have a wood burning stove?

    The short answer is yes, wood bricks can be used in a fireplace. However, there are a few things to understand about wood bricks that make them different from cordwood. First, the wood bricks are optimized to provide heat – and may not give you the ambient flames you are used to with cordwood. They burn more like charcoal – a slow glowing burn that throws off tremendous heat. Our recommendation would be to try them in combination with cordwood first. Wood bricks make a good base to help get your fire started – and keep it burning longer.

    At $314/ton, this gets me the equivalent of 1/2 cord of wood. Is that about right? So for the equivalent of 1 cord (2 tons of wood bricks) I’m paying more than $600. I understand that these burn more efficiently and with greater btu output, but do they burn longer as well? I need to be able to get through the winter and I would typically go through 2 cords of seasoned hardwood in my woodstove. Would you suggest I order 4 tons of wood bricks to make that happen?

    what is the best way to order some? can’t find anything about it online, maybe I’m not looking in the right places.

      Sorry – we primarily sell our Cleanfire Bricks on the East coast. For your area in the upper Mid-West – I might suggest trying to find a retailer who sells North Idaho Energy Logs.

    What is the oil equivalent of one pallet of bricks?
