1-K kerosene can be expensive unless bought in bulk but this heater is great! A MUST HAVE FOR SMART
by Woody (4 out of 5 stars)
February 18, 2016

I use this heater daily during winter. On high, it easily warms my living room to 77 degrees and keeps the rest of the house from 73 to 75 degrees. On low you can subtract about 3 degrees and expect it to run for over 12 hours on one gallon of kerosene.. My house has 2,000 sq ft.

HERE IS THE BAD NEWS and the reason for 4 out of 5 stars... 1-K kerosene is expensive if bought in 1 gallon or 5 gallon cans at Lowes, Home Depot etc, (about $11 a gallon for about one day's use.). In order for these heaters to make economic sense you will need to get a container of at least 100 gallons capacity because 100 gallons is the minimum home delivery for most "bulk fuel" suppliers. I bought 250 gallons for $3.75 per gallon and this will last me for 3 winters and cut my electric bill in half. This heater comes with a cheap, thin, substandard wick which I replaced before I ever ran this heater. Good wicks are about $15 but should last many years if you maintain the heater. See YouTube instructional videos for maintenance details. Not hard to do but needs to be done for the heater to run at it's best. There is a slight odor but it shouldn't hurt you if you run the heater as it should be run.

To buy something that works like it is advertized

I had been looking for one of these for months, when I finally found it I was glad, now I wish I would have not wasted my money, I have had it two weeks and the first two days it worked great, but since then it failed miserably, I did the carbon burn on it several times now and it is no better, the flame adjust switch sticks and it will not go to full flame, it throws out Carbon monoxide because the flame doesn't get fully lit, it is extremely hard to light now and when you cut off the switch you manually have to push the lever up by hand, of course I see the return window was up so I am stuck with a crappy heater that I cannot use, STAY AWAY,, and I have called several times, need to send this back because it doesn't work but can't now my window ran out

Works as Advertised.

I read quite a few product reviews on this unit prior to purchasing it. My concerns from all the reading were the ignitor not having longevity, the wick not performing well after several burns, excessive odor and also the wick lock wearing out. I've only used Corona DK-23 up to this point. Happy to report after about 15 lights and shutdowns NO major problems. I did learn that the ignitor is less effective to light when the kero is Low, or the wick is due a residue burn. once I burn off the wick, fill the tank, the wick lights with some reluctance, but it does light. Also, when shutting down, you must use the push button shutoff. If you force the lever up to the off position, it will damage the catch slot and not stay fully up. After manually lighting, I found it a bit tricky to align the burn tube for a good seal. if the tube is off a smidge, it will blow carbon. so try to manually light as little as possible or fiddle around with burn tube (orange part). I light this in my garage, then bring it in. I run a water humidifier that helps cleans the air of any kero odor. I notice very little odor if any. I carry the unit out, then shut off. All it takes is one drop of raw kero from the tank anywhere, and you will smell that nasty stuff. so be careful when filling the tank and I don't foresee any problems. I only run this unit when temps are in the teens or low 20's. I run a wood pellet stove but my kitchen is quite a way from the wood burner and I found this unit more comfortable for the dog and my feet while I'm on my cold tile floor. only reason I didn't give the 5 star, is because the ignitor system is not 100% reliable. otherwise, i'd buy another if I needed to.

Works good

I'm no stranger to kerosene heaters. Always had a large round one for backups. They usually put out to much heat for me and I have to turn them on and off which is a pain. So I bought this smaller radiant heater and it's perfect. The heater looks good, is of good design and materials.

Great helper during the winter season.
by RoyLegrand (5 out of 5 stars)

This heater is our winter savior! It doesn't just heat the room, but does it in a much faster manner, thus creating nice and comfortable leaving environment when it's most needed. We usually use this heater in order to boost up the heating procedure and, once the temperature has been reached the desirable level, we turn it off. That helps to save the level of oxygen in the room, to save the fuel and the electricity. Another good feature of this heater is that it moves the excess moisture form the leaving space. We leave near the ocean and, in winter time, severe fogs, strong winds and ocean mist get "into the bones". The heater makes the room warm and cozy.

The wick should be serviced regularly, according to instruction. It really helps maintaining the flow of the flame - and the life of the filter itself.

Some people comment on the kerosene odour, and it's, indeed, evident during the refilling and at the moments of igniting-warming-up and of the extinguishing the heater. But sometimes some regular cooking brings more fume than this device does. And it, as well as the smell of the kerosene, goes away with a brief room ventilation. I personally do not find the smell of the kerosene much offensive. It's, of course, my personal opinion. Once it's heated, there hardly any smell at all. The same goes with the intervals of no usage: the canister is quite well isolated. The electronic ignition works well only with the fresh, new wick. Otherwise the spark eventually stops reaching the wick. I have expected that form the start and found that, even after proper wick adjustment, the ignition isn't as reliable as with the new one. But igniting the heater with the match is no hassle at all.

Great heater!
by S Ray (5 out of 5 stars)

We use this in our house instead of the electric heat. Huge savings. We buy the dyed kerosene in bulk (55 gallon drum) for $3.50/gallon. A full tank lasts us 14-16 hours. If we use it just in the evenings for a couple hours then it last us the entire week on one tank. On the weekends if we run it all day it lasts a full day and a couple/few hours the next. This heater if ran the entire day will heat our entire house to a very comfortable level.

I will mention that the dyed kerosene does definitely effect the wick and the performance of the heater. You just need to be sure to run the tank dry until it burns out on its own about every other tank. Then be sure to use a toothbrush to lightly brush the wick to make it soft again before lighting the next tank. Sometimes even after that process it does not burn as hot/well but it is able to get to the correct burning temp by adjusting the wick. It just does not seem to burn as high as the clear kerosene. But keep in mind that you do not burn the clear kerosene at its highest level anyway. You end up turning the wick down to its optimum level.

Highly recommend!

Good for a smaller space or to supplement regular heating ...
by Flydaddy99 (4 out of 5 stars)

We were looking for something to give us some added heat in winter since we rely on two heat pumps which are very expensive to run when temperatures drop below 50 degrees outdoors. We have been using this unit for a few weeks now and are impressed. Works well! Good for a smaller space or to supplement regular heating source. In our case, we are all electric with heat pumps in a large house. With the downstairs heat pump thermostat set on 70 degrees this little heater is able to supply enough heat to maintain the temperature downstairs in a well insulated house when it is 40-50 degrees outside.Without the heat pump kicking in. It is not enough to hold a comfortable temperature in the colder weather therefore, we ordered the 23,000 BTU heater for the colder weather. We expect the combination of this 10,000 BTU unit and 23,000 BTU unit to heat the entire 3500 sq ft house if needed. The CTN-110 runs a good 11 hours on about a gallon of fuel which costs us $4.59. Early tests of the 23,000 BTU unit have proven these units use about twice as much fuel.

One strong suggestion is to run any kerosene heater in your garage or outdoors for a full tank of fuel before you use use them in your house. This will burn off the anti corrosive oils used in the manufacturing process. They do smell when you first fire them up but, this disappears after seasoning them about 8 hours.

Better than electric heaters
by Mr Hyde (5 out of 5 stars)
November 17, 2014

I just started the 4th year of use with my KeroHeat CTN-110 and I couldn't be happier with it. I use it as the primary heat source in my one bedroom apartment. When I buy anything, I typically research as much as possible before making a decision, and I think I chose perfectly this time. I looked into small wood stoves, window pellet heaters and anything else I could think of. After I researched all the possibilities, I decided I would try a kerosene heater. I had some doubts because I heard a few negatives about using kerosene heaters, but I've since come to learn that if used properly, there isn't really anything to worry about. I had heard they were dangerous, but research showed that electric heaters proved to be far more dangerous statistically. Yes, kerosene heaters can be dangerous, just like any heater, woodstove, pellet stove or fire place can be dangerous if not used safely. But if used properly, kerosene heaters can be safer than other heaters, especially electric space heaters. Another negative I always heard was the smell and possible carbon monoxide. Well, after burning off the initial smell from being new, it hardly ever smells at all other than a little when starting it or turning it off. Mine can heat continuously for up to 13 hours depending on wick setting without any noticeable odor. And as far as carbon monoxide, I think it's always a good idea to have a carbon monoxide detector just in case, but mine always reads zero when my heater is in use. I can leave it on all night without worrying about a wire sparking or shorting out like a space heater could possibly do, or an ember from a fire place popping out on to the carpet or wood floor. I just love it. I almost bought the 23,000 BTU model, but I saw from a lot of reviews that they use a lot more fuel. The CTN-110 is a 10,000 BTU unit and to me, it seems like more, and it sips kerosene. I often have to turn it off or crack a window on cold nights because it gets to hot in my apartment. I turn the unit off when I go to work and turn it on when I get home and it heats my apartment fast. If it's freezing outside, I may close the bedroom door or block the kitchen doorway with a curtain for a half hour or so just until the rest of the apt heats up, but it'll go from very cold to very comfortable in 15 - 20 minutes and I have to open up the bedroom and kitchen. Like I said, I did a lot of research before deciding on my kerosene heater. I learned that kerosene heaters are the main heat source for homes in Japan, and besides wood, kerosene heaters were the main heat source here in the USA before electricity. The "Perfection Kerosene Heater & Stove Company" was huge 100 years ago and there are many "Perfection" Kerosene heaters around today and still in great working condition. I'm sure a lot of people who are considering a kerosene heater have some of the same concerns I had, well I'm one person who has been won over. When I decided to purchase a kerosene heater, the next question was which one ? Well, after a lot of research, I decided on the KeroHeat CTN-110. If I remember correctly, there were 3 or 4 different brands that all looked very similar, but after reaching them, I found out that they were not all alike. The CTN-110 was by far the best reviewed. The only thing that I don't like is that I have to fill the fuel tank once every day or two during the coldest days of winter. But it's not a big deal, the tank comes right out and it takes about 2 minutes to walk outside and fill it. I actually look forward to using it on those freezing nights, and I think my cat loves it even more than I do. She is an indoor/ outdoor cat who comes and goes as she pleases, but she hates the cold. She will come in from the cold and stare at the heater from about 2 feet away. After a few minutes, she is stretched and sprawled out on the floor in front of the heater just soaking up that heat from the floor. She will gradually move further away from the heater through the night because it gets so warm and I always have it on the lowest wick setting. If I get up during the night to use the facilities or turn the heater off because its to warm, my cat is laying on the floor in the kitchen as far away from the heater as possible. The only thing I really worry about when it comes to my kerosene heater, is if a guest knocks it over. But that has never happened and it does have a safety turn off switch if it does get knocked over. I just make sure any guest's realize that there is a kerosene heater in the corner, but it's never really been an issue. If I have a party or something, I wouldn't use it. Bottom line - It's a great heater and pretty cheap to operate. I think I paid about $110.00 for the heater and I estimate it cost's me about $80 - $100 per month to heat my place. I will occasionally run my furnace but I'd say I use my CTN-110 as my primary heat source 90% of the time. I love it.

NO PRODUCT SUPPORT! Many calls later, not resolved!
by John Dillinger (1 out of 5 stars)

This heater does not work. After about 3 weeks of trying, I have not been able to get product support from Sengoku. My heater's problem; the burner assembly has an extremely uneven set of flames. Part of the burner has no flame above the edge and part has flames 2 inches high, and there is no way to adjust. Would like a new burner, but cannot reach telephone support after many calls. Also, Amazon Product Support has called & emailed & applied paperwork to Sengoku support without a reply!

I said that is nice but how do I get the fire out
by Paul T. Humphrey Jr. (1 out of 5 stars)
April 17, 2015

On the first day of use, when I tried to turn it off, the off switch broke off with the fire still going. I called the support line for help and they said they'd send me a replacement. I said that is nice but how do I get the fire out. The guy told me to let it run out of fuel or shake it really hard. Eventually, I took it outside and shook it way harder than I was comfortable with but the fire kept burning. I bet the damned thing will keep running when the fuel runs out. I got the fire out by wrenching the control shut. I sent the documents requested to the email address as instructed but have never received my replacement. Don't buy this.
