How to identify and use EPA-Certified Stoves in different kitchen or fireplaces

This guide will explain the differences between the different types of stoves that are EPA-certified and what they do. Understanding these basic categories will make it easier to shop for stoves. Using a proper and professional chimney plays a vital role in order to enjoy the performance. 

These are the Basic Categories of EPA Certified Stoves that would be in need of a proper chimney effectively. Check out Faber 3d chimney review before buying any kitchen chimney for both residential and commercial segments. 

Two-sided fireplaces can be operated with the doors on one side and the doors on the other. In Residential sectors, Always explore the Inalsa chimney price list in order to compare and finalize the product.

In recent years, the wood stove industry has made great technological advances. New designs that burn wood more efficiently, cleaner, and safer have been developed by the EPA.

We are not there yet. Existing inefficient, outdated systems are still in use. There is also a new list that could be problematic with the new technology.

EPA Regulations

The U.S. Environmental Protection Agency (EPA), established rules in 1988 to ensure cleaner operation of wood stoves. All stoves manufactured in the United States must be tested and designed to comply with strict emissions control and efficiency standards. We will be covering the different types of stoves and explain how they are more efficient and how it benefits the environment as well as the stove user.

Not all stoves are exempted from the EPA regulations.

Different types of wood stoves

If you don’t know what is out there, it can be confusing to go to a stove shop. There are many models to choose from, including small and large, cast-iron and steel, as well as enameled or black. What can you do to make sense of all this?

Don’t panic! It is easy once you are familiar with the basic categories.

All the main categories will be covered, including Franklin stoves and modern catalytic units. Let’s first define key terms.

Clean Burn

This simply refers to burning the material without releasing too much smoke into the atmosphere.


This can be a tricky topic, as efficiency can be measured in many different ways.

Efficiency of combustion

Comparing the actual heat produced to that produced if all combustible materials were made into heat.

Heat Transfer Efficiency

Heat transfer efficiency is the ratio of heat entering your home to heat produced.

Overall Efficiency

This is the difference in the heat that your home receives compared to what would happen if all combustible materials could be converted into heat.

The most important thing homeowners care about is overall efficiency. Each piece of wood should produce as much heat as possible in your home as possible.

For those who love facts and figures: Stoves older than EPA-certified generally have a 50% efficiency or lower. Stoves that are EPA-certified pass at 63%-72% or higher. We will be covering both the old as well as the new here, including:

Glass Doors

Over-firing a fireplace is the best way to break through glass doors. You can also burn large quantities of pine needles, pizza boxes and other items. Thermal shock could also be caused by items that pose a fire hazard. Tempered glass can withstand extremely high temperatures when heated slowly and cooled down slowly. Tempered glass can be damaged by rapid temperature changes.

A hot glass of wine will burst if it is dropped into cold water. Thermal shock is what you’re experiencing. It can also happen to fireplace doors.

Thin glass doors are more likely to break than thicker ones, as you might expect. Glass that is 3/16″ thick or more is used for better quality doors. Some doors come with a lifetime guarantee against breakage.

Thermal Shocks

To reduce thermal shock, keep the fire a few inches from the doors. It is a good idea to keep at least six inches between your doors and the fireplace grates.

This is not something you can do at home. Some sales representatives will use a poker to knock a door down on the showroom floor. This shows how thick tempered glass doors can withstand heavy abuse. However, the glass will crack if it is hit hard enough. Don’t use tools or logs to smash the glass, especially if it is thinner.

Kitchen Ventilations

If you have a fireplace with two openings, and have glass doors, it is necessary to operate the fireplace either with one door open or both closed. Keep both doors open if they are not of good quality. A fireplace that has one side open and one shut can cause extreme heat to the other set. This could lead to the glass breaking.

How to fix the Damage

Screens that are damaged or warped. The screens made of sliding-mesh can warp over time from heat but can be easily replaced. You can measure the mesh’s height and width, not the opening of your fireplace. Then you can buy replacement mesh at your local stove shop. Your chimney professional can help you remove and install the mesh.

A standing or gate-style screen can be replaced if the frame is good but the screen is not in great condition. However, it may be cheaper to purchase a new one. For more information, contact your local stove shop.

Inoperable, damaged or missing ash pit doors. A few masonry fireplaces include an ashpit door. This is a small opening in the bottom of a firebox that leads into an ashpit under the fireplace. For more information on ash pits, see page 18, Cleaning up. Replace the door if it is damaged or missing. The door will usually lift out. Take what is left of the old stove and measure the hole size to the local stove shop.

Penetrating oil can be used to open doors that are not closed but still have some life left. It might be worth taking the door apart and fixing it in your garage.
