Developed by GraceFire LLC


The StoveCAT ECD is a  product of GraceFire LLC using the proprietary Clear Skies Unlimited catalyst coated reticulated ceramic foam as the critical design component. GraceFire was founded a year ago in preparation for the recent EPA update to the New Source Protection Standards for residential wood heaters. See Grace Fire Video below.


The goal was to develop a simple but elegant retrofit device for older, non-EPS certified wood burning stoves. The unique design of the Grace Fire wood stove retrofit emission control device is directly related to the development effort and lessons learned from extensive work on three previous products. We have been diligently working for over a decade to bring the Clear Skies catalyst coated reticulated ceramic foam into the wood burning appliance market. We have successfully demonstrated dramatic particulate reduction, typically 80% to 95%, in three wood burning devices: stoves, open hearth fireplaces, and outdoor wood boilers. Two Clear Skies products using their proprietary catalyst coated reticulated ceramic foam are now on the market: the CS-200 StoveCAT aftermarket stove combustor and the HearthCAT™ retrofit for open hearth wood burning fireplaces. A third product, the PureSky™ retrofit for outdoor wood boilers is in final development.
Revolutionary Pollution Control Device
After 15 years of research, development and testing, we are proud to offer the revolutionary StoveCAT ECD Emission Control Retro-Fit Device for all wood heaters. The StoveCAT ECD simply attaches to the vent pipe on top of a wood stove to direct the pollutant filled exhaust through a state-of-the-art catalytic assembly. When the exhaust temperature exceeds the required catalyst light-off temperature of about 380 degrees F, the catalytic components convert the organic particulates and other criteria pollutants into harmless water vapor and carbon dioxide. Powered by a Clear Skies Reticulated Structure. See StoveCAT Components.

Then, at exhaust temperatures below the required catalyst light-off level, the catalytic system acts as a mechanical filter to capture and temporarily store organic matter. When the exhaust temperature once again reaches the catalyst light-off level, the captured organic particulates are catalyzed. The StoveCAT ECD is designed so that it doesn't cause any harmful back pressure. This is due to the unique three stage catalytic design. Watch Video
Unique Three Stage Catalytic System
Transparent View
The StoveCAT ECD Retro-Fit Device is powered by a patented Three Stage Catalytic Cartridge. The most important feature of our three stage catalytic system is that the wood stove exhaust will continue to flow even if the catalyst becomes totally blocked with organic particulates. This is critical to insure that no spillage occurs under any conceivable situation during wood stove operation. If there is any buildup of organic material on the catalytic components, it will be burned off during the next high-burn period resulting in a self-cleaning device requiring no maintenance or replacement for at least 5000 hours of operation. 

                         

In addition to reducing harmful particulates and gases, a key feature of this device is that it increases the energy efficiency of the stove. It does this by breaking down organic compounds in an exothermic reaction - a chemical or physical reaction that releases heat. It produces heat energy in a manner that needs less energy to create the reaction than the amount of total energy released. This additional energy is produced by the catalytic combustion of the organic compounds that are normally expelled into the atmosphere as pollution. Much of this catalytic energy will radiate back into the living area as radiant heat. More energy and less pollution.
Works on Virtually any Wood Heater or Wood Stove
According to US EPA, approximately 10 million wood stoves are currently in use in the United States, and 65 percent of them are older, inefficient, conventional stoves. Just 20 old, non-EPA certified wood stoves can emit more than 1 ton of fine particle pollution. In many areas of the country, wood smoke is the single largest source of PM 2.5.

The StoveCAT ECD is designed to solve this environmental crisis. It is designed to work on virtually any wood heating device with a flue system of 8" or less. There are hundreds of different wood stove brands and models. A simple stove collar is used to transition from the exhaust of the wood heater to the bottom of the emission control device.

This device can be easily installed in about an hour. Special adapters may be required for certain appliances. The StoveCAT ECD has also been successfully evaluated on indoor wood furnaces.

Average 80% PM Reduction

The StoveCAT ECD was tested at Omni Environmental in Portland, OR. The total reduction in particulate matter averaged 80% compared to baseline measurements from two different wood heaters and the average moisture content of the fuel was above 30%. Additional testing showed 80% reductions in PAH, VOC's and a 60% reduction in CO.

Why Choose the StoveCAT ECD ?



For many years, the US EPA and Air Districts across the US have been searching for a device or system that can be retrofitted to existing freestanding, uncertified, residential wood burning stoves that will significantly reduce the emission of fine particles (PM2.5) and polycyclic aromatic hydrocarbon (PAH) pollutants. They also wanted the device to be economical and easy to implement and not create a hazard to the occupants of the house or harm the environment in any way. We are proud to offer the StoveCAT ECD Emission Control Retro-Fit Device as the solution for all wood heaters.


The StoveCAT ECD is the ONLY passive system available to reduce wood heater emissions. Several other technologies are available that have computers, blowers, heaters or other complex system requirements. All of them require electrical power or maintenance. The StoveCAT ECD is totally passive with no moving parts and no power required. The The StoveCAT ECD is also the least expensive system to purchase and the least expensive to operate. The StoveCAT ECD also produces additional thermal energy. Much of this catalytic energy will radiate back into the living area as radiant heat. More energy and less pollution.
