The Test of Our FireplaceThe blower was a success, but the fireplace was a total failure. Here's why.These kinds of fireplaces are just for looks. The fire in the firebox is actually insulated from the inner metal casing of the firebox using insulating fireboard, much like insulating firebricks, so heat from the fire never gets to the metal, at least not in any quantity. So it doesn't help to have a better blower because there is very little heat transfer to the metal double shell of the firebox to begin with. The inner and outer shells around the firebox never get hot. So these double-shell fireboxes are a sham. Totally useless because the double shell is insulated from the fire.How I Intended to Use the FireplaceWe save money by using a setback thermostat. In the winter, after 10 pm the HVAC turns off and the house cools down to 55°. In the morning, the HVAC turns on automatically to heat the house back up to 68-70 by 8 AM, (on at 68°, off at 70°). When the sun comes up, we open our insulating blinds to let the south facing sun come in. With solar gain, we usually don't have to run the HVAC during the day, unless it's cold and there's no sun. This way we keep our electric bill down to what a super-energy-efficient house would use, or oftentimes even better. That's pretty good for a double-wide that was designed for Georgia (we discovered later).I had hoped to use the fireplace to initially heat the house up instead of using the HVAC, but it didn't work at all. I couldn't bring the house up even 2°. That's how pitiful these modern built-in fireplaces are. They are so insulated that all the heat leaves the fire (at 800-900°) and goes straight up the chimney stovepipe, which is also insulated. Maybe it's for fire protection, but in any case, these types of fireplaces are only good for making s'mores :(I'm working on another plan to use the heat from the fire with a heat exchanger placed inside the firebox. I won't have time to build it this winter, so we're stuck with our existing methods of cost reduction. At least now we know that the fireplace is useless in emergencies, except to sit up close in front, with open glass doors to get some radiant heat.The problem is not the blower, the problem with these types of fireplaces is that fireboard surrounds the fire and insulates the metal from the fire. So the surrounding metal enclosure that surrounds the firebox NEVER gets hot. You can never get any worthwhile heat from these decorative fireplaces and the the glass doors keep any heat out of the room. The metal never gets how enough to transfer heat to the room. I my tests, with a roaring fire, I could only bring the room up 2°F from 55° to 57°. These fireplaces are for show only. Totally useless, no matter how good the blower is.

Although it is slightly noisy when at certain speeds this top down fan kit works very well. The installation is very simple and easy. Although I purchased the kit that contained the thermostat I did not use it as it has to be used in a area that is over 165* to close the circuit and allow the fan to function. So I bypassed it. The power hookups are on the left side of the fan. This is good as it allows the fan to be away from the damper of the insert. Instead of using the included foam I just placed it upon a rubber shelf pad. This keeps the fan from moving around and holds it in position no matter what speed we run the fan at. I plan on placing a plastic covering in front of the fan in the shape of a U with holes drilled into it on the lower part to allow air to flow through it and keep some of the noise down. A good workaround fix for cheap price as the original fan kit is over $375.Second posting…. Installed for over 1 month now and we found even though this unit put out a lot of air at high speed the noise can be reduced by running the fan at a lower speed. We have found the speed that is the best for us is 1/4. No noise to speak of and still pushes a good amount of air.

We have a older gas log and all the actual heat building up inside the fireplace. It arrived early just ahead of the snow storm. Husband installed it and it instantly moved the air out into the room and raised temperature in the entire house! Only thought was wish the wiring was heavily duty but we are just going to wrap with heat tape for added protection.

I got this to replace the 20+ year old fan in my Desa gas log fireplace. It is nearly identical, except that mine has magnets to hold it to the back of the firebox and this one has some oddball foam strips that are only sticky on one side. Anyway...I installed it in about 3 minutes. Then I turned it on. HOLY COW is this thing loud. And I mean like it is 'loud enough that you have to turn the volume up on the TV when it's running' kinda loud. I have a variable speed adjustment that I can utilize, but then it minimizes the purpose of the fan--MOVING AIR. So we found a happy medium for now. I set up a return for it, but figured it wasn't worth the trouble. I'll keep it and turn the speed down a little. But the reviews that tell you it's loud, IT IS. It sounds like a jet taking off...forever. Not sure why this one is so much louder than the original, but I'll be searching for a replacement soon, I'm sure. LOUD, man....LOUD.
