Some Flaws, but it does what it's meant to do. HEAT!
By Calamity Jane
The Pros -- This thing delivers the heat! I live in a 980 sq. ft. mobile home with an open living room and kitchen. Even during the coldest months this unit kept me warm during power failures. The heat even traveled to the farthest bedroom, not heating it to the fullest, but keeping away the chill. It runs silently.The Cons -It does not run for the 12 hours, as stated on the outer carton. I suppose if you heated a very small bathroom it would regulate itself to the full 12 hours. I have to refill the tank every four hours. Since the unit is rather heavy and bulky it's difficult to carry it outside for refueling. It's even heavier on the return trip because of the full tank of kerosene. The carrying handle doesn't feel secure enough to haul that weight.Unless you run the tank completely dry, this unit flares up and sends a cloud of black smoke into the room during shutdown. A kerosene-stink will linger for half an hour. It has to be taken apart and cleaned every few days to remove the carbon build-up on the wick. I have not yet been successful at removing all that carbon.A kerosene heater is not for wimps or for those who won't follow safety instructions. It can be dangerous.I wouldn't recommend this product for someone looking to run it all winter long to cut down on their heating bill.I would, however, recommend it for someone wishing to have an optional heating source available during emergencies. If the only choices are to freeze or find another heating source, this will unit will do the job well.I believe the Cons (as stated) are typical of all portable kerosene heaters, so I will not fault this unit in those areas. With the exception of the misleading "runs for up to 12 hours", this unit does what it's supposed to do. That's why I give it five stars.

Poor quality factory wick
By Matt
I've had this heater for just less than four weeks now. In the interest of disclosure, I'm certainly not an expert, and this is my second kerosene heater - I also have a dyna-glo 23k BTU that I've been using happily for about a year and a half.I was very excited to get this smaller 10k heater since the worst of the winter is about over in my area, and the Dyna-Glo is too much when the outside temp reaches forty or so. The item came double boxed and intact - great shipping and packing from Amazon as usual.I put it together (it was easy and the instructions were simple) and then went to carry it downstairs and nearly dropped it from the top steps because the handle fell out - this is definitely my fault, and luckily I hadn't filled it yet and had fast enough reflex to grab it before it tumbled down. Since then I've bent the handle inwards so that it fits a bit tighter and hopefully that won't happen again. However, the handle bends considerably when the unit is picked up, especially with a full tank, and needs to occasionally be bent back into place so that it can swing freely. I think it needs a heavier gauge handle to be moved around safely. It probably goes without saying for any kero heater, but definitely don't try carrying this while it's lit.After lighting it the first time, I noticed no visible smoke, but it had a sooty odor - not the normal mild kerosene odor I noticed with my other heater from time to time. I looked at the book which said an initial odor was normal until the first dry burn. So I lived with it, using it on and off for about a week until I felt it was ready to burn dry. After (double) burning it dry the real problems began. The burner assembly would no longer burn red to the top, the blue flames were obviously way too low while the adjustment was as high as it would go, the sooty odor got worse, and most times after lighting it, the flame would just flicker in a small (two-inches or so) part of the wick. Frustrated I'd put it out and try to relight it - again and again. After a few days of this, I got a flame going, and tried to dry burn it again, then again. After dry burning it, the wick was soft on the top, and stiff everywhere else. I tried pinching it with pliers, flexing it around with my fingers, and dry burning it again. The result was no better. The more I tried the worse it got.Today I put in a new wick, and everything is back to normal ... and NO SMELL at all and the heat output is considerably better than even the first time I fired it up. I'll edit this later if the problem returns (and bump it up one star if it doesn't), but I believe that the manufacturer put a poor quality wick, trying to save a few pennies, so the unit was not getting hot enough to burn clean and odorless. A wick should last about a year for most people, not less than a month (assuming it was ever good at all). But hopefully this solves the problem and saves someone else the same frustration that I had.Normal burn time on a tank is probably around fourteen hours as others have mentioned. The wall guards do not add any stability and are an annoyance if you don't actually put it near a wall, so I took them off since I keep it in the middle of the room I'm trying to heat. The manufacturer needs to add a small wire door to the front grill to facilitate easier match lighting - I had to buy the long eleven inch matches to reach down in there (break of the charred end and relight them with a lighter to make them last longer).In summary, I've not been happy with the heater for the short time I've had it. If the whole problem actually was the wick and not some design problem, I'm sure I'll be content with this unit for many years.Edit 03/29/09: After using this an additional two weeks I can confirm that the new wick made all the difference. So if you bought this and are having smell or heat output problems, try a new wick. I'm using a Kero World 91009. I've also decided not to bump this up one star as promised. After comparing the two wicks I can see difference in construction and I feel that Sengoku's QA could and should have seen the difference as well. -* for bad QA and -* for all the time I had to spend troubleshooting because of it.

Did everything right!
By Cool
I'm a young kerosene lamp collector but never encountered an unboxed Kerosene heater before. Decided to give it a try this winter since many gas stations here in Philly dispense undyed and untaxed 1-K cheaply ($2.80 in October 2009) and heating bills last few years are $200/month on average for our well insulated house. After reading reviews around, I was pretty settled on this omni-radiant design, but had reservations with the actual burning time due to short wick per this site and Mile Stair's site (highly recommended).Then I had a chance to pick one up several weeks ago. Only $10 as the seller was moving so I figured there's little to loose. It's a 2005 run in like new condition. While it's the first time I got my hands on a kero heater, mechanically there is really no difference between it and any center draft lamps, save everything is in bigger size! Lighted it up easily and enjoy the cheap heat every since.Two things I'd like to elaborate on this heater:1. It burns 15 hours on a single fill when the outside is in 40s and 50s and my 600 sqft second level is toasty 75-78 degrees with a slightly crack window! Update on Dec. 1, 2009: The kerosene gauge on the heater must be designed for trial lawyers, not actual usage. If one religiously follow the gauge from "F" to "E", s/he may get 7 hours out of "one full tank" at most. Nowadays I fill it well into the red zone on the gauge and burn it down another 3-4 hours after "E" mark. This way I can easily get 15 hours. In case you wonder, the record time I timed is almost 19 hours (!) on Low setting before kerosene completely runs out and it starts to smell due to dry burn.2. I start and extinguish the heater in the garage so there is no smell in the house. The heater is delightfully light-weight for a grown man to carry around very carefully. In comparison, my small 14-candlelight kerosene lamp gives off detectable smell. Of course the burn efficiency is different purposefully.Maybe I'm lucky but this thing is doing everything right. This winter I will save hundreds of dollars easy with this baby.I've been shopping at Amazon.com since its inception. This is the first time I'm posting a product review even though I did not purchase through the site. Need I say more on what kind of recommendation I'm giving?!Updated on 10/1/2010: Fall is here and I'm looking forward to putting the heater into another winter of service. In the unusually cold and snow record setting 2009-2010 Philly winter, my total kerosene cost is mere $172, which is less than my monthly heating bill in the previous winters!
