The following description concerns the Kerosun LC-56

It is obvious that those of us who end up with this type of heating have cost as a priority. Starting with this primary factor, I concluded that this is the most economical heating method, having ruled out electricity, gas, and oil. Consequently, it was a one-way street.

This particular heating method has the unique downside of the smell that everyone mentions when turning it on and off. The save button only turns off the device when it "reaches" the desired temperature. If you want it to operate indefinitely, turn it off.

The rooms heat up immediately, even the adjacent ones. In terms of heat output, it is excellent. You will be warm in a minute.

To turn it on and off on the balcony, you can only do so if access is straight. If you need to lift it because there is a threshold at the bottom of the access, it will turn off. And since most homes have a threshold at the balcony doors, you will never take it outside.

I only use the Crystal 1, which is supposed to be odorless, but the smell is still there. The inferior extra kerosene has a much stronger smell. It is tolerable, but you can easily tell the difference.

The device is Japanese = Guarantee.

The digital display does NOT light up as shown in the photos.

Regarding the technical specifications, the information provided here is completely wrong regarding the thermal output in power, which is referred to as kw = kilowatt-hours = electricity consumption. Go to the official website and select TECHNICAL SPECIFICATIONS from the menu:

The power consumption is only 26 Watts per hour. The reviews claiming high consumption are unfounded.

Otherwise, it is an excellent way to warm up immediately, quickly, and much more economically, as long as you overlook the tolerable smell for me.

One of the best choices for a home without central heating and generally installed radiators. Very good performance. Heats up quite quickly. Like all heating devices, you need to learn its tricks in order to operate it correctly and economically. On the first day, I had it on maximum and it burned about 4 liters in 10 hours. Then I realized that in save mode it burns much less and the performance has a small difference, so the consumption issue was resolved. Now, about the smell issue. When turning it on and off, yes, it smells quite a bit. When I turn it on, I close all the rooms and leave only the one where the stove is open for 5 minutes. The smell goes away quickly. The same goes for turning it off. During operation, every hour I open 2 windows for 2 minutes for ventilation. This should be done for anything that burns inside the house in order to let oxygen in. I always operate the dehumidifier at the lowest setting at the same time and I have no problem with humidity. Having low humidity helps a lot in distributing the temperature everywhere and not locally, and if the dehumidifier has an ionizer, it completely removes the smell of the stove. For those who have a problem with the smell during operation, the reason is as follows: 1) Poor combustion due to altitude. There are 3 settings depending on the altitude you are at. 2) You have it on maximum all the time and every 2 to 3 hours it cuts off to self-clean, and that's when it emits a smell. 3) The same happens whenever it changes the combustion scale (being an inverter). Sometimes the conditions may be such that the stove is in the transition phase for a long time and it fluctuates in intensity, which can make it smell a lot. I solved this by permanently setting it to save mode. Otherwise, you can set it to maximum for 1 to 2 hours if the house is very cold and then immediately switch to save mode. Now that kerosene has also been included in heating benefits, something will change. Regardless of the fact that it now costs 55 to 65 euros for 20 liters, which is 3 euros per liter, and no one sets any limits for them.

UPDATE: I installed four office chair wheels on the stove for better mobility. Please note that the screws should be self-tapping and not too long.
The stove is the same model as the lc 44. The only difference is in the electronic system and, of course, the price, which is approximately 100 euros more expensive. Everything else is the same. It's just that the 45 is a newer model. Since it is for a 75 sqm area, it requires a large space. To work properly, make sure there is nothing within 70 points perimeter. Also, there should be a slightly open window or balcony door in the area where it is located. Approximately half a finger thickness. It smells slightly when lit and extinguished. But with an open window for three minutes, everything is fine. It works perfectly with kerosene, specifically kerosun crystal. With any other fuel, it smells strongly. I prefer to buy directly from the dealership, as the kerosene is more economical, around 40 euros for 18 liters. In terms of consumption, with the selected temperature of 21 degrees in the stove, it burns approximately 0.26 liters per hour. Be careful when transporting it while it is operating because if moved forcefully, it will extinguish. It quickly heats up the space. Contact the dealership for any questions. I hope I helped

I have owned this stove for 5 days now. The first negative thing for me is the smell it emits at the beginning, during ignition. However, this can be easily solved by constructing a base with wheels and moving it with a trolley outside or to a space like a bathroom with an open window for the first 10 minutes of operation. If you don't want it to smell when you turn it off, leave it in save mode for half an hour before. Also, as most people write, the best kerosene you can use is Crystal one, and I say this because there was no smell at all inside the room during the entire operation of the stove. Now, let's talk about the performance of the stove. I heat a unified space of a living room, dining room, and kitchen, around 70 square meters, and it heats up very quickly, even in save mode it gives off heat like radiators. Yesterday, on Saturday, December 18, 2021, when it was very cold, we didn't need any additional heating in this space. Of course, to tell the truth, if there is autonomous heating in the house and the apartment complex uses it, meaning a boiler, it is better to turn on the radiator because it will heat the whole house more efficiently and economically. In my case, the boiler in the apartment complex is not working, so I have to resort to other heating methods. Another disadvantage is the price of kerosene, 45 euros for 20 liters of Crystal one, so before someone buys the stove, this might be its major drawback. Now, as for consumption, I don't have an opinion yet. I will come back in the next period to inform you, as the total usage I have done is almost 24 hours of operation, in total over three days, so the 7-liter tank it has hasn't emptied yet.

Well, today is December 26, 2021, Happy New Year and Merry Christmas. After measuring, the stove in save mode lasts for 32 hours with a refill of 7.5 liters. The cost per hour that I calculated is about 0.55 euros for one hour of fuel. Assuming that I will use it for 4 months, 8 hours a day, a total of 960 hours, it will burn around 530 euros of fuel during that time.

I have installed it in a large open space living room kitchen. As for the heat it produces, it is very good, pleasant. No comparison with electric heaters, air conditioners. It emits a slightly annoying smell when starting up and a less annoying one when turning off. During operation, when you are in the room where it is functioning, you don't smell anything, but when you come from outside or from other rooms, you get an indistinct smell, probably from the combustion, just like when you enter a room with a lit fireplace, no matter how well the fireplace draws if it is a traditional open one. Just like the fireplace, it has a flame and consumes oxygen, so it needs to be opened occasionally to let fresh air into the room. For a 70 sqm open space, I would buy the larger one. Anyone with a sensitive nose should not get it, the truth is that everyone perceives it differently. It consumes approximately 100ml per hour, regardless of the model, and 1000 kw. The power consumption is minimal, so you won't see a significant increase in your electricity bill. It hasn't created any humidity on the windows or walls for me. The base with the wheels is very convenient for transportation or changing the direction of the air with a finger. For maintenance, I clean it once a week with a vacuum cleaner to remove dust and wipe the grilles with a damp cloth. Finally, during the winter, I get it serviced at the dealership, just like I do with an oil boiler. Also, I want to emphasize that the warmth in the room remains even after turning it off for a considerable amount of time, just like with a radiator, and I would highly recommend it

I bought the Kerosun LC-56 and found the Kerosun LC-52 used, so I have an opinion and experience from 2 different devices that are essentially the same in size and capabilities. From what I understand, the LC-52 is an older model without any differences.

My purpose was to heat a 45sqm office space for a few hours every day during the cold winter days, as the air conditioning couldn't cover it.

- It smells when opening and closing, as everyone says. You can't lift it and move it while it's in operation because it shuts off.

- However, it also smells during use: This is what interests most people. Yes, it smells quite a bit, especially with the "Odorless" kerosene "Kerosun Crystal ONE". However, because I have also tried a gas heater, the Kerosun smells less. You can strongly smell the odor when coming from outside the clean air, and not so much when you are inside the room, but you still feel the gas in the atmosphere. It is definitely not healthy. Indirectly, but clearly, they also write it on the instructions: "this product is not suitable for primary heating purposes."

- It heats quite well, but what's the point if you have to ventilate the room well every hour to avoid suffocation. When I say ventilation, I mean opening a window for about 3 minutes. This way, cold air enters again and you lose a lot of the benefits. And let's say you don't want to ventilate well because you don't want to lose the heat, it will automatically turn off due to lack of oxygen.

- The kerosene is very expensive, 37Euros for 20 liters, which will barely last you 5 days for 8 hours each day at low temperatures of 20-21 degrees.

- Personally, because I don't want to inhale the gas, I keep it open at a low temperature at night to keep the office warm until the morning when I will turn it off, ventilate, and turn on the air conditioning. If I need additional heat, I use electric heaters for the hours I will be there.

I would not recommend it for anyone who wants to keep it open and be in the space it heats. Definitely, an air conditioning unit with an inverter is more cost-effective in the end and healthier.

P.S. The old one I found used was stored in a humid place for 1 year and it rusted a bit. So, for those who buy it, they should make sure not to keep it in a humid place.

P.S.2. If someone finds a good, truly odorless and economical kerosene, please let us know here.

P.S.3. I also tried it in a small 12sqm room, it easily heats it at the lowest intensity, but for the gas, it needs to be opened every 20 minutes

I have it since 12/2019 to heat a 18sqm room. The room has 3 windows with double glazing and two internal doors to unheated spaces. The doors have glass but are sealed at the bottom. The stove is placed on a platform with wheels for easy movement even when it is operating, and if it shakes above a certain limit, it automatically shuts off. I did this mainly to light it outside of the specific space and transfer it to it with slow movements, to avoid the smell it emits during ignition and extinguishing. Now I light it in the specific space by opening doors and windows for five minutes. Of course, if I am going to stop it, I take it out of the room and that's it for the day. The smell it emits either at the beginning or at the end is not tolerable for me and this makes it inconvenient. I cannot easily light it and extinguish it at will. The stove heats up the room very quickly. Already from the first 5 minutes with doors and windows open, you feel warmth. The stove always smells, even with the supposed "odorless" Crystal One kerosene. When I leave the room and re-enter, the smell becomes noticeable, otherwise you get used to it, although sometimes the atmosphere is not tolerable for me. Sometimes I have the feeling that I am entering a room that was previously smoked in. The stove is set at 20 degrees and in this specific room, it burns the 7 liters that its container can hold max in 29 hours. So, with today's price of 27 euros/18 liters, it costs 0.36 cents per hour of operation. That is, with 8 hours/day for a week = 20.16 euros. For approximately 1 month, it costs about 80 euros. I consider this to be a high cost, especially when it comes to a room of only 18sqm. Everyone judges.
