Non vented furnaces

[snowgator]

I know this has been asked in the past, but Iam new here and Im setting up a new wheel house shell. I am wondering what the opinions out there are on the non vented furnaces. I have venting isues the way I want to lay out the house and I am really leaning towards one of thes units. What do you think?

Go with a smaller suburban forced air furnace. You can build them into the cabinet, and it has a small vent for outside.

I will never put a ventless heater in any of my houses again.

HMM non-vented doesn't sound very safe.... I have a forced air furnace and it is great...Pro's- air temp is the same on the floor and ceiling, thermastat controlled, holes stay ice free. I have the vents directed at the floor. Cons- runs off a battery. What ever u do make sure u put a CO detector in it.

Thanks, My biggest issue is I wont have 110 volt on the ice. No generator.

i like my empire radiant with a termostat 18k vent free

I can get 2 days off a marine battery in temps -25. I usuallt have 2 batteries.

Thanks to all. I will take all info into consideration. Its time to set down on the ice and nap.

just tore out my non vented and replaced it with a vented. I too had to re-arrange the layout of the house but I got sick of the windows sweating and icing up and also had concerns of CO and lack of oxygen (had safty shutoff but still concerned).

My new vented needs no power to operate, now I just need to find computer fans to make it more effecient.

Good luck

I've had one in my wheel house since new. Never had a problem. Had a CO detector, never went off. They are safe. As stated above, your windows will sweat and fog/frost over. I also always cracked a window a hair. If you can put a vented in, I'd go that way, but I wouldn't worry about a ventless. I'd also take into consideration how often you'll sleep in it. If you're going to be in it every weekend, I'd go vented, not only for safety but for the moisture issues. If it's only going to be used a few times, ventless might be your choice.

You will regret it if you don't vent it now.

I've had the direct vent Empire on my 10 X 20 for 15 years and it really works great w/o any electricty required. I did add a few computer fans to keep the air moving and that really makes a difference. I agree 100% with the other posters for safety you need to vent your heater.

Some of the direct vent furnaces need the fan running to work. You will be much happier if you stay away from those. They are noisy too. Fleet and others sell direct vented heaters that you can buy a fan kit if you want but don't HAVE to run it. They are wall mounted,take very little room, and stay cool to the touch.

If you plan on sleeping in it remember your life is on the line. Yes the ventless heaters have safey mechanisms on them but these are mechanical or electrical devices. Ever have a mechanical or electrical device fail? I won't trust my life to one.
