High Temperature Fans? For a fireplace...

[Kelemvor]

We have a 2-sided gas fireplace in our house but it doesn't have any sort of fans built into it to disperse the hot air. This means we just have to rely on what radiates out from the glass on each side which doesn't really help to heat the room. There is electrical wiring that goes to the fireplace specifically for a fan, but it was not installed with a fan.

There is a decent size opening on top of the fireplace where I could easily put a couple small fans that would help blow the air from that section out into the room. I'm assuming that cavity gets pretty darn hot so I'm wondering if this is even feasible and if anyone know of any fans that can run in really hot temperatures.

I thought of just using some PC case fans but don't know if they'd basically melt if it gets too hot. I don't know how hot it gets for sure as I've never measured it but I'll see if I can do that at some point once we get it turned on this winter.

Anyway, does anyone know of any fans specifically designed to work in really hot temperatures or have any suggestions I can look into?

Thanks.

Yeah, you'd want to get a hearth fan. Can also google for "fireplace blower".

Interesting, they have grate heaters too:

I have a fan on my wall mount gas garage heater, I got it direct from the manufacturer of the heater, it turns on and off automatically by temperature.

Have you tried the manufacturer? I know mine would melt PC fans in less than 5 minutes.

It surprises me that there is no fan. A gas fireplace without a fan is basically worthless and probably operating at an insane cost. Are you the original owner? It wouldn't surprise me if the blower got loud so a previous owner just went ahead and removed it.

I replaced the blower in mine, it was $85 and took all of 5 minutes.

most fans for fireplaces mount underneath them and blow air up and around and then it kind of comes out the top slots but not with a ton of force. I was hoping to be able to put a fan on top of the fireplace that an blow directly out.

The installer said that the fans they put underneath on a 2-sided fireplace don't really push much air out so they didn't usually recommend them to people. I'm just looking for an alternative method.

I would be careful blowing hot air off the top of the fireplace.

Mine pulls in from the bottom around the back and out the top. I'm not dead yet. Yet.

The official fan would blow it out the top too. I'm just looking to move the location of the fan, not change where it blows out from.

My gas fireplace has an optional fan, and again, it blows out the bottom.
Yeah, I would be careful about blowing air off the top.

Then you have a strange fireplace blower. All blowers I've seen take are in from the bottom, blow the air up around the back/sides of the fireplace, and out the top. That's how they standardly work.

Heating systems do not work by sucking hot air out of a furnace, they blow cool air through the furnace that comes out hot.

Look on Amazon for blower motors. They come in all sorts of shapes and sizes, and many can handle being in higher temperature environments.

man you guys are fast.

lol we had to get one installed on our wood burning stove. but it helped a ton keeping it going.

Important to note is that the air in the room should never mix with the air from the fire. You want to heat the air in the room by passing it through or over the cavity without mixing with the air from the fire. Don't want to end up with carbon monoxide poisoning.

Yep, you're right.
The fan is in the bottom, but it blows up the back and out the top.

I have a Heat N Glo.

Just buy the one that is made for your unit? Hope the manufacturer knows best on how to circulate air around their product.
