Gas ventless wall heater or electric heater??????

Ok fella's,

I'm looking for an extra heat source for a very cold bedroom, about 200sf. All I want is 65f as cheap as possible running cost, not up front or install cost. I have NG so I can go that route.

This heater would only run prior to and during sleeping hours, I estimate about 8-10hrs a day, that includes the warm up period. The room would start daily around 45-50f and I want max 65f.

I like the small gas wall mount option (10,000btu), but my wife suffers from bad migraines sometimes triggered by smells. Does anyone use a small blue flame heater in a bedroom or other smaller room and is there any oder???? How about moisture/humidity problems?????

The bedroom is a converted garage and does not get any airflow from the stove. Also a concrete floor below 2x4's laying flat isn't helping things much. Not my design, bought the house this way and needed the extra bedroom. I didn't plan on burning wood for heat when we bought this money pit, just kinda happened and I refuse to stop using wood.

I was told a 1500watt electric heater would cost around $45-60 a month to run, does that sound right??

Thanks,
Charlie

Those look real nice, but maybe a tad too high priced. I should say that the budget is around 300+-. I'll install myself.
Thanks for the link anyway.

The whole headache thing kinda changes things. I didn't think about the smell till the wife reminded me. Thats why I was considering an electric. I believe our kwh price right now is 0.06c, but is going up as of the new year here. I was just doing an estimate of around 0.10c. The price cap on electric expired in 2011.

I hear ya guys, not a good idea for ventless. I bought a ceramic heater to get us through this year. At this point it will be every bit of 500-600 to install a direct vent heater. I'm thinking about just adding a small third stove. Why not, I already have wood gathering stuff and experience. Just running three stoves seems a tad much. Thanks for the info.

Your killin me guys!! LOL

The room is a converted garage and the man door to enter is from an unheated sunroom. I could put the stove in the sunroom, but with a flat roof I fear ice problems. The long wall of the bedroom backs the dining room of the main house. I just told my wife I'm gonna cut a huge hole in the wall for air to pass through, then when company comes over I'll just hang a large portrait of the family over it to hide the hole! LOL I might actually do this that's the scary part. This BR will eventually be converted back to a garage either when we lose a kid or I make a BR in the basement, with outside access per code.............someday that will happen just not in the near future.

The electric heater will have to do this year, that gives me the rest of the year to get a vented unit installed. Who knows maybe building a that BR in the basement could become priority. Doing that would solve more than one problem.
