Select Blade Finish:
By Aime from Penrose, CO on January 6, 2014
We have one with 3 blades that is probably 15+ years old, and now needs to be started manually with a little push. Can we get another one with 3 blades?

By Collin C. - NFI Master Hearth Professional on January 7, 2014

Answer:
Because of improvements made in design of the blades and to further cut down on noise produced, the manufacturer has revised all of their fan designs to a two bladed style.

By Barbara from Santa Rosa, California on January 19, 2013
Are these Ecofan AirMax 812 stove top fans efficient for use on propane gas heaters with open grate tops and non-opening glass front doors in a 24 ft. x 24 ft. room with a 19-foot high open beam ceiling?
By Collin C. - NFI Master Hearth Professional on January 21, 2013

Answer:
The 812 AirMax is an excellent choice for use with a propane stove, as it will begin to circulate air at a relatively low temperature, unlike other models. Your room size will not be an issue for circulation, but the high ceilings will have an effect on amount of available heat. The fan will assist in circulating the air further into the space, but a good deal of heat will ultimately be lost to the ceiling. If you have ceiling fans in the room, I would definitely recommend their use to force some heat back downwards.

By Steve from NJ on November 7, 2013
I just bought this fan and think it works great. Would a second fan help even more or is that going to be too much? I have a Vermont castings extra large dutch oven.
By Collin C. - NFI Master Hearth Professional on November 7, 2013

Answer:
Because of their ability to work in tandem with no ill effect, it is certainly possible to use more than one fan upon your stove. Some very large stoves can even use 3 fans, but 2 would likely be the best number for your model.

By Carrie from Massachusetts on January 7, 2014
Our stove is set into the fire place. It is not an insert and there is clearance on the top and around the sides. I was told that I would not get enough cool air to circulate around the back and would burn out the fan. Is thus true?

By Collin C. - NFI Master Hearth Professional on January 7, 2014

Answer:
The Ecofans often do suffer in these types of installations. Not only will the fan motor be prone to overheating, but the fan will also not work well otherwise. The fan depends on a significant temperature difference between the upper and lower parts of the fan. The temperature difference is what energizes the thermal generator which powers the motor. A confined space tends to heat the upper section to nearly the same temperatures as the lower part, leading the fan to spin very slowly or not at all.

By Sharon Dean from Watertown, NY on November 6, 2012
Could you give me the exact width of the base?
By Tyler M. - Fireplace Specialist on November 6, 2012

Answer:
This fan's base measures 4.75" wide and 3.25" deep. The entire fan is 9.75" tall and the blade diameter is approximately 9".

By Roy from Las Vegas, NM on January 7, 2014
What makes this particular fan your best seller?
By Collin C. - NFI Master Hearth Professional on January 7, 2014

Answer:
The high amount of air movement offered by the fan, coupled with the longevity of the product and its almost nonexistent operating costs, make this item one of our most popular stove accessories.

By Sandy from Fiddletown,CA on January 11, 2013
In the cold months I don't usually let my fire go out. Is this fan good for continual use? And what is the life of this fan?

By Kevin E. - Fireplace Specialist on January 14, 2013

Answer:
These fans are ideal for continuous use. They are built to run all winter long. The manufacturer offers a one year warranty. However, this fan should provide you with service far beyond the expiration of this warranty.

By Gary from Pocono Lake, PA on January 31, 2014
I have a Gilbraltor wood/coal free standing stove that I mostly burn coal in. Will this fan work with a coal stove?
By Collin C. - NFI Master Hearth Professional on February 3, 2014

Answer:
As long as the top of the stove does not exceed the 650 degree maximum that is listed for this model, the fan can most certainly be used. Regularly exceeding the 650 degree limit can damage the thermal generator used with the fan.

By Vinny from Floral Park, New York on March 4, 2014
I have a traditional brick fireplace with a gas insert. Where would I put this or is there something else I can use to help disperse the heat?
By Tyler M. - NFI Certified Specialist on March 4, 2014

Answer:
If your insert does not have any listed options for its own blower, an Ecofan may be a good idea if you have enough room to place it on top of your insert with space behind it to enable air circulation. However, this particular Ecofan is only suitable for use with a wood stove, your gas insert would need a
Caframo Ecofan CA 806. The dimensions of the base for that model are approximately 2 1/4 inches deep by 6 1/4 inches wide.

By Edward from Southington, Ct. on January 21, 2013
Can I use this on top of my kerosene heater? It is a Aladdin blue flame. The top is 9 inches in diameter and runs up to 600 deg. F.
By Collin C. - NFI Master Hearth Professional on January 22, 2013

Answer:
Although not designed with this type of installation in mind, there would not be an issue with using the 812 AirMax fan for this purpose. I do not recommend using any other model, as the 812 is the only one that has a motor with a high enough temperature rating. I would also verify that the top of your heater is perfectly flat, as the fan will not function well if placed on a domed or dished surface.

By Glory from Lancaster, PA on January 1, 2014
Does the color of the blade make any difference to performance? For example the weight of the blade, etc.
By Tyler M. - NFI Certified Specialist on January 2, 2014

Answer:
No, the color options are for purely aesthetic purposes.

By Jingying from NY on November 14, 2013
I just purchased the AirMax 812 wood stove fan. After I read the instruction, I am not sure it can be used by my wood stove. My stove was installed in the wall. The largest portion (about 3/4) is in the wall, the outside of the top surface can just barely place the stove fan. The pipe was in the wall. Your instruction said that the fan shouldn't be used directly in front of the stove pipe or at the front of the stove. I took the pictures to show you what kind of stove I have and where I put the fan. Can you tell me if this fan is a good fit for my stove? In the instructions, it said the surface temperature should be lower than 650 degrees. How can I know what the temperature is? It will be inconsistent, because the temperature always changes with the fire. I couldn't find some thermometer with an alarm. Can you please help me?
By Collin C. - NFI Master Hearth Professional on November 14, 2013

Answer:
The surface temperature of your stove can be determined by using a magnetic thermometer or a laser thermometer. It is recommended to use a magnetic thermometer for any wood stove or insert, as this will make sure that the stove is not overfired.

The fan can start operating at temperatures as low as 150 degrees, which should be achieved even at the front of your insert. The fan is facing the wrong way in the photos and should be rotated to face the room, rather than the stove. It would be rare, even with the hottest fire, for the stove surface temperature to exceed 650 degrees. As such, there should be no damage to the fan.

By Tommy from Louisiana on December 13, 2013
What is the difference between the 810 and the 812?
By Tyler M. - NFI Certified Specialist on December 13, 2013

Answer:
The basic Ecofan 810 model is capable of moving 105 CFM of air, while this larger 812 model can move 150 CFM. The operating temperature between the two is very similar. Besides differences in blade color, these are the only things that separate them.

By Gerry from Maine on December 1, 2013
Do these fans blow air into other outlying rooms or is a motorized fan better for that purpose?
By Tyler M. - NFI Certified Specialist on December 2, 2013

Answer:
Indeed, a motorized blower made for your wood stove would be a better option for maximizing heated air circulation to adjacent rooms.

By Gizell from Buffalo, N.Y. on January 8, 2014
My wood stove has a shroud around the entire stove. The top sits about 3" above the firebox.
Does the fan have to sit on the fire box itself? Or, will it operate as efficiently sitting on the vented shroud?
By Chris on January 8, 2014

Answer:
The fan itself will begin to spin at around 150F, but require no more than approximately 250F to be creating 175 CFM. Being that the top is only 3" above your firebox, I would expect the shroud would easily reach the temperature. However, I would use a stove thermometer or an infrared thermometer to ensure the shroud is reaching a high enough temperature allowing the fan to operate effectively.

By Jan from China Village, Maine on September 16, 2013
Our fan no longer circulates. What can we do to 'fix' it?

By Collin C. - NFI Master Hearth Professional on September 17, 2013

Answer:
It is likely that for a long term fix, the fan motor will need to be replaced, as they do lose their ability to produce voltage over time.

However, the motor seal can also be oiled by lubricating the output shaft. The fan blade set screw will need to be removed and the fan blade set aside. Using a product such as 3-in-1 oil, lubricate the motor shaft while the fan assembly is laying on its back. Slowly rotate the shaft to allow the oil to work into the motor windings. This will often help to extend the life of the fan motor.

By Allison from Westport, MA on February 3, 2014
How well would the AirMax fan work on a very small (600 sq ft capacity) cast-iron wood stove? I am trying to heat a 300 sq ft room, and the heat really doesn't travel far from the stove except to go straight up to the ceiling. I would buy one of these fans if it could better circulate the heat around my cold kitchen! What can you tell me?
By Collin C. - NFI Master Hearth Professional on February 4, 2014

Answer:
These fans work very well to induce a flow of convection, better distributing heat further away from the fan and delivering the cooler air back to the stove to be heated. The fan will achieve maximum airflow at temperatures as low as 250 degrees. Even though cast iron stoves typically have lower surface temperatures than plate steel models, you should still achieve a high enough surface temperature for the fan to work well.

By Callie from Utah on June 5, 2014
What if the surface temperature of your stove exceeds 650 degrees? Will the fan still operate? Will the fan be damaged?
By eFireplaceStore on June 5, 2014

Answer:
The thermoelectric generator can be damaged if the wood stove surface temperature exceeds 650 degrees for prolonged periods. Almost all wood stoves will have a surface temperature of less than 650 degrees under normal operating conditions, although some models can go higher depending on design.
By Tedd from VA on June 5, 2014

Answer:
As the thermocouple is designed to run via heat, there is an upper limit to the temperature it can withstand. There are wires,etc that at >650 may damage the components. If your woodstove top plate is >650, your stove is probably too hot internally. I've had mine quite hot and no issues, and it makes a good indicator when the stove needs wood as the fan turns very slow.
By Carrie from Nokesville, Virginia on June 5, 2014

Answer:
I have never exceeded 650 degrees, so I cannot answer that question. However, with using this fan it tremendously reduced the amount of wood I used. Took me awhile to get it right. Many nights had to open the windows as I got the house tooooo warm :) Love this product!
By Rick from NH on June 5, 2014

Answer:
I have not had mine up that hot but at 600 degrees it was working fine. I would guess your answer should come from the tech people at Ecofan.
By Glenn from Long Island on June 5, 2014

Answer:
Sounds like more of a technical question for the manufacturer. I do not have a temperature gauge but I can tell you the fan has performed flawlessly even during some very hot fires.
By Shaun from Idaho on June 5, 2014

Answer:
We don't have a thermometer on our wood stove, however, when the stove gets really hot the fan starts to make quite a bit of noise (kind of like a rattle).
This of course catches our attention and we either move it to the front of the stove top, or take it off and set it on our hearth. I am not sure if the fan
would be damaged if we left it on, but my guess is the blades may get warped.
By Mike from Salem, MA on June 5, 2014

Answer:
I have pushed the stove to 650 and it still works fine.
By Rich from New York on June 5, 2014

Answer:
The fan will still operate at 650 degrees or higher. I don't know if the fan will be damaged, according to the company info we shouldn't operate the fan at higher. I have an 810 also and ran it higher than I should and it still works fine. To be safe run at the recommended temperatures. Hope that helps
By Matthew from Sunapee, New Hampshire on June 5, 2014

Answer:
I've never known the temperature of my stove but I've had it cranking as hot as possible & the fan worked beautifully.
By Big Black Bear from Boulder, CO on June 5, 2014

Answer:
Sorry, can't answer your question, I only burn pine and rarely get above 600 F. Probably best to ask Caframo.
I WILL say it is a great little fan, it does manage to circulate a good amount of air, is attractive and silent, everything it is advertised to be, would recommend it!
By Gary from Elkton, MD on June 5, 2014

Answer:
The fan runs on heat. The hotter the stove the faster the fan runs. The entire fan is metal, and I can't imagine the fan melting. The heat can't damage the motor. Therefore the very hot stove should not damage the fan.
By Dave from Mill Hall, PA on June 6, 2014

Answer:
Sorry, I can't be of help regarding temp. I have a propane stove which has no integrated fan, so it's convection out the top grate of the stove. I'm careful where I set the fan so its not directly over the louvered surface but works just fine. It needs to be close enough to the heat to work but close to a cooler surface (wall behind) to blow across the hot surface. I have an infrared heat gun but sorry I don't recall how high the temp was. But I'm sure it wasn't over 650. I know if it was over 650 I wouldn't have bought it.
By Monte from Pine, CO on June 6, 2014

Answer:
Been there, done that. The flue temperature gauge on my wood stove was reading 900+ degrees. How did I know? I had loaded the stove with too much little kindling trying to restoke a dying fire. I realized my error when I heard my Ecofan minutes later. It sounded like an airplane ready for takeoff. It was really cranking. I immediately shut down the damper and, using a hot pad, lifted the fan off the stove via the wire hoop on top. Within 5 minutes, both were back to operating normally. The Ecofan apparently experienced no damage and has worked fine since. I wouldn't recommend temperatures above 850-900 degrees for either the fan or stove, but an occasional blip doesn't seem to be a big deal. I generally keep my stove at 500-800 degrees with no problems. I would imagine continued high temperatures will shorten the life of the electric motor (replaceable). I love and still marvel at my Ecofan. Hope this helps.
By Jude from Upstate New York on June 8, 2014

Answer:
Yes, this fan still operates over 650, but the manufacturer says it may damage it, so when I first got it I tried to monitor the stove temp, and took it off when it got to 650 or higher. My little fan is on top of a fireplace insert that has no built in fan. This Ecofan makes NO noise, none, and spins super fast. (I sometimes give it a little twirl to get it started). I found I do not need my stove over the 650 range now to heat the room. This little fan helps me keep the fire temp lower, and still heat the area, but with less wood. Great fan and made solid.

By Dave from Colorado on November 4, 2013
On the 812, almost all the reviews are from woodstove owners. As we have a freestanding gas fireplace, would we expect a lower performance as the surface temperatures may not be as hot as wood? What are your thoughts?
By Collin C. - NFI Master Hearth Professional on November 5, 2013

Answer:
From my experience in testing these fans in a controlled environment, the 812 does indeed move less air at lower temperatures, when compared to the Caframo Ecofan GS 806 Heat Powered Fan for Gas & Pellet Stoves. The gas fan seems to achieve maximum velocity within 50 above its 150 degree starting temperature, while the wood burning fan is still picking up speed up to approximately 250 degrees.

I recommend using a heat gun or thermometer to test the surface temperature of the gas fireplace. If the temperature exceeds 350 degrees, the 812 would be the better fan to use. Any lesser temperatures would be better served by the 806.

By Brenda from Akron, Ohio on November 9, 2012
We heat our entire house with a fireplace insert (very open floor plan). The electric blower has been intermittent, so I am considering our options. I love the idea of an electricity-free, silent fan. Will you please confirm that this would work on an insert? I understand that it would need to be positioned at the side or at an angle for proper air flow.

Also, please give me a realistic comparison of its effectiveness to what a standard electric insert blower puts out. I'm eyeing the AirMax model because of the large space that needs to be heated, but I don't know if this is even realistic with this type of fan.
By Collin C. - NFI Master Hearth Professional on November 9, 2012

Answer:
As long as the insert has a significant amount of protrusion onto your hearth, the Ecofan could be a good solution for your needs. The fan will start to operate at as low as 150 degrees, and can move up to 150 CFM of air, which is greater than most electric blowers can manage.

The only downside to this type of system is not the amount of air, but the amount of heat it will move. Your built-in blower will always be more efficient, as it is pulling heated air from around the stove casing, which has a considerably higher temperature than the heated air that radiates from the top of the insert. Because of this, the fan is likely to be a bit less effective than your current blower.

By Sarah from Maine on November 21, 2013
We have a small wood stove that is made of soapstone. We often use it as our only heat in the winter (no heat upstairs). Our downstairs is basically a big open square with a staircase in the middle. The side of the house that the stove is on gets quite warm (lower 70's) but the other side of the house is often only in the lower 60's. Would adding a fan to the stove improve this heat discrepancy? Do you have any idea by how much?
By Collin C. - NFI Master Hearth Professional on November 22, 2013

Answer:
Use of a circulating fan would indeed offer better balance to the average temperature of the entire house. It is difficult to say how much of a difference will be made without knowing the exact square footage of the home, but on average, a fan can make a 4 to 5 degree difference.

By Nick from Sellersville, PA on January 10, 2014
Can I use the Eco fan Airmax powered wood stove fan for my fireplace?
By Chris on January 10, 2014

Answer:
The Caframo Eco Fans will operate only when placed upon a surface in which the temperatures will reach approximately 225F. If your fireplace has a flat space in which to set the fan, it may be prudent to ensure the surface reaches a high enough temperature to operate the fan.

By Paul from Willunga, South Australia on July 20, 2014
I have seen various letter combinations after the 812 designation. These obviously signify different models but what are the pros and cons of each?
By eFireplaceStore on July 21, 2014

Answer:
The standard 812 fan was revised from a 125 CFM output to a 175 CFM output fairly recently. When this occurred, the "AM" nomenclature was added. The remaining stock we had of the 812 fan has been depleted, so all fans shipped now are the "AM" version. The remaining letters are used to indicate blade color. The physical blade design and CFM output is the same for all colors.

By Marilyn from Greenwich, NJ on September 26, 2013
What material is this fan made of?
By Collin C. - NFI Master Hearth Professional on September 27, 2013

Answer:
The fan body and blades alike are made from cast aluminum.

By Dorothy from Brockton, Massachusetts on November 22, 2013
Could you use this fan on any wood stove and is this model your biggest one?
By Collin C. - NFI Master Hearth Professional on November 22, 2013

Answer:
This model is indeed the highest CFM model that we offer currently, with an output of 150 CFM. The fan will work with any wood stove that achieves a 150 degree surface temperature, with ideal heat range between 225 and 650 degrees.

By bill closs from Rangeley Maine on February 4, 2012
I have a Franklin Stove, which does not get as hot on the top surface as an airtight wood stove....therefore which model would be best for my Franklin stove, the Airmax 812, or the model made for gas stoves ?
By Kevin E. - Fireplace Specialist on February 6, 2012

Answer:
That all depends on the surface temperature of your stove. The Ecofans for wood stoves can be used on stoves with surfaces that do not exceed 650F (345C). The Ecofan GS is specifically designed for use on gas stoves or stoves with a surface temperature between 150F (65C) and 300F.

By Ellen from Bayfield, CO 81122 on January 8, 2013
I can't order Airmax 812 without having additional fans added to my order I want just one of these! I have a gas stove and live in CO.
By Collin C. - NFI Master Hearth Professional on January 8, 2013

Answer:
It sounds like you may have looked at the fan numerous times or evaluated other models and they were added to your shopping cart. You should be able to view all items in your cart and see all items added. To remove any unwanted fans, erase the number in the quantity box and click the update button. If you have several of the same Airmax 812 fans in the quantity box, revise the quantity to "1" and click update. We can also contact you to place the order via phone if you wish.

There are several models of the Caframo wood stove fans. What is the difference in performance of each of the different styles?
By Collin C. - NFI Master Hearth Professional on January 8, 2013

Answer:
The basic 810 models are capable of moving 105 CFM of air, while the larger 812 model can move 150 CFM. The operating temperature between the two is very similar. Besides differences in blade color, these are the only things that separate them.

By Judy from Forestdale, Massachusetts on February 28, 2014
Our wood stove is a top loader. Sitting a fan on top of this would mean removing it each time we had to load the stove. Although it is simply an extra step, my question is how safe is this extra step? Will handling the fan this often damage the fan? Our more importantly would it damage us?
By Collin C. - NFI Master Hearth Professional on February 28, 2014

Answer:
It is possible to carefully pick up and set aside an Ecofan by using the supplied handle. Depending on the stove, the handle can get quite hot, so a glove should be used when moving the fan. No damage will occur to the fan if it remains upright while being moved. The fan blades are blunt and will not cause injury, but care should be taken to avoid touching them while the fan is spinning, as the motor hub and blades are easily bent.
