Mr. Heater30,000 BTU Natural Gas Blue Flame Vent Free Heater

Nothing to dislike about this product .Iwould really like to have it installed by a professional but it’s run by natural gas and I need propane seller had shipped earlier then expected

First off, I got this nat gas heater at the end of November of 2010 for a 17'x 22' finished basement room with a 7' drop ceiling. I live in the Northeast so we get pretty cold winters here. This heater was purchased for a secondary back up heating system in the event of a power failure however, I use it daily and love it. My initial concerns before the unit was installed: plumbing gas pipe, ventless emmissions, CO2, odors and function(s). I'll address all the concerns as best I can.-Plumbing gas pipe: Don't do it yourself, hire a professional, you'll sleep a lot sounder, a small price to pay for safety (it'll pay for itself in the long run anyway)-Ventless Emissions: I researched here and there and everywhere, this camp is split from what I can see, some say there is and some say there isn't any, I don't know. The next thing I cover may or may not be related to this.-CO2 and odors: I installed $40 Kidde CO2 detector 12 feet away from the heater and it still reads 0 all the time (I was expecting 5-7 ppm but I got 0, that's great). Now onto, the odors, yes there are odors, I'll admit that when I first fired this unit up I was greatly impressed with the heat output but wasn't at all happy about the smell. It was a chemical smell, which after the heater stopped running the smell soon went away within a minute or two. I would masked the odor with an air freshener when the heater ran and it was fine. It has since been a month and a half now and the heater has ran frequently on a daily basis and the odor/smell is virtually gone. A relief to say the least. I do smell it briefly at start up sometimes but that's only for a second or two. I think it was the paint/parts burning off that new heater smell so to speak.-Function(s): Although it looks like there is, there isn't a digital thermostat, It's a 1 through 5 dial type which runs the duration of how long the heater runs with some internal temp setting (ex. setting 1 = 68-72 degrees). Flame height is the same always, temp dial does not regulate height. Flame is not like pictured, it's better, it looks like what's on your stove top. Flame is a nice blue, at start up I get orange streaks, I found out that's its only dust in the air, it goes away in about 15-25 min. The fan, basically is useless, poor design, could be a lot better, I don't use it. I have a 10" Honeywell table top swivel fan blowing across the heater, left to right, it's even with the top of the unit to circulate the heat in a circle around the room. My unit is not wall mounted, it is free standing on carpet, carpet does get warm to the touch but never hot. No electric required (unless you use the fan), the spark igniter runs on a AA battery (supplied), there is no pilot when it's off.So how well does it work? Well, Freaking Amazing!!! It's instant heat!!! To get an idea of the heat output, if you have a gas stove, turn all stove top burners on at the same time, don't run the vent, put your hands near the vent away from the flame. I have 4 burners on my stove and that is what is feels like for me. The burner is this unit is about 16" long. At setting 1, once my room is warmed up, the heater runs for a minute or two then knocks off, it'll do this 3-4 times an hour. As for energy savings, I can already see it, I used to use a electric ceramic tower heater to heat (pointed at me) the room at $50+ a month more on the electric bill, that's no more and the whole room is toasty and to boot my gas usage went down slightly compared to the previous year at this time. Win, win, win.Pro's:Heat, heat and more heat. Instant heat.Energy savings (it will pay for itself)CO2 - not an issue in my setup of a basement roomLooks - it looks nice as a unit alone and when its running.Con's:Blower fan, uselessDial temp gauge - No digital temp setting (it would be a great feature and for setting lower temps too)Odor - goes away over time with useThere ya go I hope this helps you.

I have had this unit up and running for about two weeks now and I believe it was a great purchase. Skip to the to the end to see my list of pros and cons. I live at an elevation over 4800' and the Oxygen Depletion Sensor (ODS) has not given me any issues so far. It has been starting to get pretty cold outside. The nights are getting into the teens and it has kept the air inside at a comfortable 70 degrees just on setting 2. The thermostat allows up to 5 different settings which will cycle on and off until it reaches the preset temperature. I have it mounted to the wall and since we only had an electric furnace before getting this unit, I had to run all the piping myself. At first I was using the yellow gas teflon tape but kept running into leaks. I would recommend using a paste instead of the tape as it is less time consuming and not as critical to make sure that the right amount of tape was used. Most city ordinances require a pressure test to be done before they will allow the gas company to connect the meter. For me this was $65 the first time to find out what to do since I could never get ahold of anyone, and unfortunately another $65 to come back out an reinspect the finished leak free pipe going from inside the house to outside near where the meter would be, holding pressure of at least 20 PSI for 20 minutes. Just to be sure, I pumped it up to 85 PSI and let it sit overnight. This was quite an ordeal since there wasn't too much documentation through the city I could find on this. In the end all is well though, it passed and the house is toasty.Getting back to the unit, within the first day or two I noticed a lot of condensation build up on the windows. I discovered that by cracking the window in the kitchen an inch or two, the frost on the windows was greatly reduced. The fan really doesn't work that well and is kinda loud. We have vaulted ceilings and our bedroom connects to the living room, so I'm thinking about installing a ventilation fan between the rooms to bring the hot air inside the room without having to leave the bedroom door open. If I had been feeling more ambitious I would have ran more pipe and installed it near the electric furnace so that the return vent would pick up the heat from the vent free heater and pump throughout the house more efficiently. I still leave the fan circulating the air on the electric furnace without the furnace actually being on and it seems to do a really good job at circulating the air still. For now, here is the short list of pros and cons:Pros:-Heats up whatever room it is in quickly-Easy to install, used the Mr. Heater adapter kit.-Works great in Mobile Home, and is specifically manufactured for them as long as it is permanent (inspector asked me to verify)-Looks great!-Heats upwards, not directly out like the infrared heaters, i.e can use closer to furniture (could be pro or con depending on desired use)-5 temperature settings, cycles on and off-Works fine at elevation over 4800'Cons:-Fan is fairly pointless-Lots of moisture built up on windows due to the combustion of natural gas (as explained above, just crack a nearby window an inch or two to allow for the moisture to escape)That's all I could think of for now, if anything worth noting comes up I will be sure to edit this comment.
