Fireplace Heat Exchanger / Grate Heat Recovery / Heatilator / Variable Speed Fan

Description

Now in our 8th year manufacturing fireplace heat recovery systems!
This is our zero drop system, which fits fireplaces that have a 19" tall / deep opening (or less), and it includes an off/on/fan speed controller. We sell larger opening systems; just send us a note with your opening and depth size, and request more information,, or look at our other listings for our "Larger" system.
In order to use our system in any zero drop fireplace you will need to build the center of the fireplace floor up with patio stones so the system will have a perch to solidly support the bottom tubes of our system.

* Would you like to cut down on your use of wood taken from our forests?
* Fireplace too small to heat the room?
* Cost to heat getting expensive?
This fireplace heat recovery system will help you and our forests by
recapturing lost "out the stack" heat, recapturing approximately 35% of the heat that is normally lost up the fireplace chimney. A vast improvement over a regular fireplace, the system adds 24,000 BTU /hr (see actual calculations below) for each 60,000 BTU /hr generated by the fire.
If you spend 0 a year on wood your payback for this system is less than two years, and the wood carrying and cleaning chores also become easier for the same amount of heat produced. This is no toy; read what my customers say by looking at my actual feedback. To do that you just click on my name, and look at "buyers feedback". Note that it is 100% positive, and I intend it to stay that way. If you aren't completely satisfied with this system you can return it no questions asked; please see my return policy above.
This is not a car muffler or iron pipe set. There are
7
copper heat exchanger tubes in this system, the material of choice when it comes to the ultimate heat exchanging efficiency. If you believe that a steel tube set makes a good heat exchanger, then you should consider they don't make a steel car radiator; they are copper or aluminum. All the tubes are precut to fit your specific fireplace, making assembly simple, with no special tools, welding, gluing, sawing, etc. required.
The BTU per hour out of a fireplace heat exchanger is simple to calculate:
Heat exchanger BTU output is: heat recovery unit CFM X heat recovery unit tube air temperature RISE/6400 X 12000 BTU/Hr
L
ook for specific air flow and tube AIR temperature rise;
both should be stated; if not, ask for it!
This unit flows air at 100 CFM, with an air temperature rise of 130F (real life example: 70 degree air into the fan housing from the room, and 200F air coming out of the tubes).
This unit performance was: 100 X 130 X 12000 /6400 = 24,375 BTU/hr!
One critical note:
If you think you want as much heat out of your fireplace as you can get, then you are kindly mistaken. Our systems pull as much heat out of the fire as possible without causing chimney problems, and a possible fire. Please copy and paste this link in your URL to learn more if you are interested:

The bottom ash plate is made of 20 gauge stainless steel to handle the hot ash temperatures produced by the log ash ( aluminum tubes would melt in the heat produced by hot logs / ash if in direct contact with the tubes). The ash plate is 17" wide. The grate is usually wide enough to straddle the ash plate in front. Ash that accumulates on the plate is easily cleaned away. The plate does not require removal to clean the ash off, but the grate has to be removed (as usual) for cleaning.
A 100 CFM fan is necessary to provide adequate, efficient and gentle heat removal. The fan in this design draws less than a 25 watt light bulb, and can run continuously after the fire goes out without causing heat loss, as it draws air into the fan from the room, and then puts it back into the room, pulling heat from the fire and ash till it has all extinguished. The air exiting the heat exchanger tubes is about 200f when the fire is burning, producing a gentle horizontal column of warm air flow you will feel when standing in front of the fireplace. Note that blowing any harder only drops the air temperature, does not add heat energy (the air temperature rise in the heat exchanger drops way off), and the noise level of a big blower is an issue when compared to a fan, not to mention the looks.
The air box where the fan is located is a 20 gauge satin finished stainless steel to prevent rusting. The face is painted black to match fireplace surrounds. The air box stainless areas offer good reflectivity of heat away from the fan housing, reflects heat into the room, and minimizes the heat conducting into that section of the system. The fan must run once a fire is burning or hot ash is present, as the heat from the logs / ash could damage the fan if it cannot disperse the heat away from the enclosure and into the room.
The fan assembly can be easily uncoupled from the tubes if desired in the summer months when the system is not needed.
This system never requires soot cleaning, and in fact as the tubes darken from the soot in the fires (about 5 fires) the system will actually improve in heat recovery performance. The top tubes that bring the hot air out into the room end behind the fireplace curtain / damper arm so that the curtain can close and the damper arm is free to move past the tubes.
The system comes with tube assembly instructions including simple assembly pictures sent to your email address, all parts, and a 1 year parts warranty.

Please do not buy a system until we see what fireplace you have!
If you are interested in a system for your fireplace please follow these instructions, and do NOT buy  until I say it is OK:
Send us a picture or two of your fireplace and surround, including the bench area
Take measurements of the depth and height of your fireplace opening per the pictures in the gallery above
If the floor of your fireplace is not flat please tell us that, and take a picture of what your floor looks like
If your back wall of the fireplace is not vertical (meaning it tilts in as it rises) tell us that, as it will change the depth measurement
Thanks for looking!
