Question: Has the manufacture corrected the issues & problems that has displeased so many clients? The smell, durablity etc...Normally Amazon products satisfy
Document: 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.
We own the larger unit KeroHeat CV-2230 and and decided to get a smaller one for background heat. This will be the 3rd unit we have tried the first was the Sengoku CTN-110 - the control lever would not stay down so we returned it. Amazon replaced it with this model This unit is even worse! There is no control for Hi or Low and the smell is awful. I contacted Sengoku LA  - Wow - what a terrible service.
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.
I remember purchasing this item in 2010, and no matter how I adjusted the wick it continued to produce a very strong odor. I have been using kerosene for 40 years, and never encountered any issues until I purchased this unit. So I simply stopped using this heater, and went back to my old MoonLighters and a Corona on very cold days. And before I could "blink", Amazon sent me an email instructing me to return this item, and paid for the return.
i got it and had it for 4 weeks. i thougth the smell of kerosene would go awaay after burning it a few times, but i still have the smell ok the kerosene in the house bad and it burns your eyes from the smell of the kerosene.
I would be willing to give it another a try based upon what some of my fellow Amazon Shoppers suggest to me. So if some of you have had a better experience with the newer model, then please let me know.
Remember those old kerosene heaters that smoked while they were burning, and stunk up the whole house? My dad had one. The smell used to make me sick to my stomach. Well, this isn't one of those heaters. There is a slight odor for about three minutes after you ignite it. While it's heating I don't smell it at all. I've used this heater every day this winter. It DOES take a while to heat up a room.
At first this heater did smell. But after reading some articles I found out that the wick setting was set too low causing the odor. Now that the wick is set at the proper height it burns great and without a odor. Great heater for power outages and also to knock out the chill in the home. In order to get 12 hours of burn time,you must fill beyond the "F" into the "red zone" then you will get the full 12 hours of burning.
So now I have to install a replacement wick which is a pain according to the instructions. Many folks reported the same problem as I am now experiencing. With a new aftermarket wick, the reviews I read say it will operate flawlessly.I'm not real impressed with the wick situation. Quite frankly, it's frustrating to get a new Kerosene heater, only to have to replace the wick to get it operating properly.
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.
