I've used one of these for about 3 fill-ups now: about 36 hours of use. (I don't think it will ever be 16 hours on 1 gallon, but 12 is fine by me.)

It's flawless. It smells a very little bit at start-up and shut-down, but while it's running it's essentially odorless. And perfectly quiet (a very soft gurgle once every ten minutes or so when it needs to sip some fuel into some internal tank) -and it puts out a lot of heat.

I have a room that's maybe 300 square feet with 5 big windows. On a cold night (close to 0 degrees F.) this thing can warm up that room by 2 or 3 degrees in 10 minutes, and maybe by 8 or 9 degrees in an hour. If you sit across the room and it's pointed straight at you, you can feel it right away.

It easy to fill up. There's a cannister that you carry outside (garage) and fill from your kerosene container with a hand-powered siphon. Worked the first time. This may not work if your outdoor kerosene container is too low, but then you can just use a funnel. The cannister stands up nicely by itself for filling, on a level surface (like a garage floor).

There's a little window on the cannister that lets you see when it's almost empty during use -and when it's almost full during fill-up.

When you want to turn it off, you press the "extinguish" button -the big knob in the middle winds rapidly counterclockwise -makes a loud noise -and the flame usually goes out immediately. Sometimes it may gutter for 30 secs or so before completely going out.

At start-up time the flame gutters a little for maybe 60 secs before the combustor starts to glow red, then the flame stabilizes and becomes perfectly quiet. You can't really see a flame except a little bit of blue -maybe a quarter inch at the very top of the combustor.

It's very easy to start up using the little battery starter device -you just push a red button, hold it for a second, then slowly release. I've done maybe 20 starts so far on one pair of batteries. You can start it with a match instead if you want to (or have to.) But the battery-powered starter is nice.

The back and the top and sides of the unit stay COOL TO THE TOUCH after an hour of use. Probably indefinitely.

This gadget is an example of a perfect combination of high-tech (the way the combustion works) and low-tech (it's .... kerosene, after all.)

There aren't many things this good. Cast iron pans, maybe? And ... um ... windmills that really work ? I don't know.

I don't see how I could ask this thing to be any better.

I've been using kerosene heaters for about 25 years now and really like them. I picked this unit up at a local Tru-Value because my old Kero Sun was malfunctioning. My first impression of this product is it's well put together. It looks well designed and feels solid. I prefer the square units over the round ones as the square units have removable fuel tanks and thus are more convenient to refuel. This unit also has a few nice touches like a little lip on the fuel tank handle which makes it a bit easier to remove. Another nice touch is a cover for the batteries. This is the first time I've seen this on a kerosene heater. This helps resist battery corrosion.

I've used kerosene heaters for two purposes; to lower my heating bills and to have a backup source of heat during power outages. I use my main furnace to heat the house up to my desired temperature. I start the kerosene heater up at the same time and position it below a ceiling fan turning clockwise. Once the house is warmed up, the furnace cuts out and the kerosene heater keeps the house warm for the rest of the day. If your house is reasonably insulated, this should work for you as well. If it's really cold, like in the single digits or below, your furnace will kick on but a lot less frequently. I figure for every dollar I spend on kerosene I save three on my heating bill. I haven't had an energy bill over $200 and I have a 1700 square foot house. At this writing, kerosene is about $3.00 per gallon. Even leaving the unit on 16 hours a day, I spend about $60.00 per month on kerosene in the coldest months.

Kerosene heaters do require regular maintenance. If you don't clean the wick, you could be harmed by fumes emitted by a dirty wick causing the fuel to not completely burn. It's very simple. It's called dry burning. Place the unit in a well ventilated place, preferably outside. Remove the tank and put the wick in the ignite position. Light the unit and let it run dry. Once the flame is out, take an old toothbrush and brush the burned carbon off the wick then thoroughly vacuum the unit. Then put a new tank of fuel in and you're done. If you perform this maintenance for every five gallons of kerosene used, which should be once a week, you'll be fine. The unit should be fully cleaned and serviced once a year by a professional or by you if you know what you're doing.

For a little effort and common sense, you will save hundreds of dollars every heating season. The unit will pay for itself in just a few months.

I am going on my third season with this heater and it is serving me well. My parents always used a kerosene heater and now I use one myself. They are really great...don't let propaganists try to tell you they are "death traps." I have a 1200 sq ft row house built in 1949 and frequently use my kerosene heater all winter long to take some stress off my heating bill.

It sounds like some of the other reviewers were not using the correct fuel. You should use UNDYED, clear 1-K Kerosene. Do not use kerosene that is dyed red (the IRS requires kerosene sold for certain purposes to be dyed). I tried this dyed kero once and it wreaked havok on my wick...the wick gets all gummed up with residue so it will no longer raise and retract after just a few gallons. This is just another way that the government screws up our lives.

With the correct fuel, this heater produces beautiful, radiant heat. It is very cosy, and like having a little fireplace in the room. Cats and dogs love to sleep in front of it. You do have to be a little bit of a "hands on" person to manage a kerosene heater, but it is well worth the little amount of work.

Honest reviews on World Marketing KW-11F 10,000 BTU Radiant Heat Indoor Kerosene

I bought this heater to suppliment our oil furnace so I didn't have to heat the whole house. It works good as far as heat out put goes, easily heating 400 square feet of space. There isn't any kind of heat adjustment on it, other than to keep the wick burning at an optimum flame. There were times I wished I could turn it down a notch. I liked the fact you could remove the tank for filling, but the directions say to shut the heater off before doing so, so you can't expect to keep it running for extended periods of time. On one such fill up, I apparently didn't get the tank seated correctly, even though the top door did close correctly. The wick started going out and really stunk the place up. The heater does need to be lit and extinguished outside, which means carrying it very carefully so as to not trip the automatic shut off. In doing so, the wall guard which I still haven't figured out the reason for, tends to get in the way. The weight is also off centered with the tank being on one end. The heater isn't real heavy. You just have to compensate for most of the weight being on one end so you carry it level. The heater does need to be elevated at least a foot off the floor if you are using it on anything other than bare concrete, because it does tend to get very warm for about two feet in front of it. Fortunately, the bottom, sides, and top stay cool, so it can be set on most anything that is stable. If it were not for the having to light it, extinguish it, and let it burn outside for at least 5 minutes until the odor dissipates, I would give it more stars. It is probably just the nature of the beast and not a fault of the heater. I didn't have any other trouble with it, and it worked as advertised. I would say that it is a good heater to use in an emergency, but not one for ongoing suplimental heat.

I bought this kerosene heater at local hardware store, not Amazon, but I own the same model. I have to say it was worth the $150. I had a big 'ol 100 year old home south of Buffalo, NY and this did a nice job of keeping it warm. I did leave the windows open a crack for fumes, but we didn't have central air so that didn't affect the furnace. My ignition button was "not firm" I want to say...can't think of how to describe it...but we are really rough on things. I don't think I used it but once..always lit the wick with a match and never had any problems. Like the other's say, to fill it, you have a one gallon rectangle tank you pull out, I go out on the porch to fill it up, then you cap it and just slide it back on in. It has a fuel gauge but I found that hard to see. I never had any other kerosene heater so I can't really compare it to anything. But, it does heat up well and that was its purpose. Oh, and I think it has an automatic shut off so if it gets tipped or something the wick gets extinguished which is very handy and always worked for us. (Look into that though...I used this a couple years ago.) And like the other reviewer, I think I got 12 hours on 1 gallon pretty sure I filled it up once in the morning then once at night. So, $6 a day just over $180 a month for heat if nothing else is used (we had a pellet stove too though). But I would DEFINITELY not recommend this for people with allergies or lung issues, or anyone that doesn't have common sense when it comes to fire. (Don't point it directly towards a couch, tablecloth, etc. cause it WILL get HOT! This product is worth the $150.
