Kerosene Heaters 101

Kerosene heaters are unvented, portable space heaters designed to use kerosene instead of electricity, propane or other petroleum-based fuel. Though it is extracted from oil products, liquid kerosene is much less flammable and volatile than gasoline.


Advantages of Kerosene Heat

New technology, design features and advances in manufacturing have made these units safer and more convenient in recent years. As long as you know what to look for, there are good reasons to consider buying a kerosene heater:


Kerosene Heater Safety Precautions

It’s important to practice safety at all times with a kerosene heater. All the safety features and tech advances yet invented haven’t removed the potential danger of an open flame in proximity to explosive fuel.

The National Agriculture Safety Database (NASD) lists proper safety precautions when operating a kerosene heater. Here are important guidelines:


Determining the Size of Kerosene Heater you Need

Kerosene heaters are rated by their British Thermal Unit (BTU) output. To determine how many BTUs you need, perform a simple calculation:

1) Multiply the square footage by the height of the area to be heated.

2) Multiply this figure by your insulation factor: (2) for good insulation, (3) for average, and (4) for poor.

The resulting figure is the approximate BTU rating you need.


Use Clean Kerosene

There are two grades of kerosene, K-1 and K-2. The grade to buy for an indoor kerosene heater is the more refined K-1 fuel, because its sulfur content will be below .05%–this allows for unvented operation. The lower K-2 grade is for use with vented heat.

K-1 kerosene comes in two varieties: a clear and a red-dyed liquid. Theoretically these are the same, since the dye was only added to designate non-taxable (fuel) kerosene. Red-dyed fuel is a little cheaper due to being untaxed, and it is supposed to meet K-1 standards.

In reality, the red dye does present some issues. It stains the wick, making it a bit more difficult to see its condition. It also causes more clogging and increases the frequency of needed maintenance.

PRO TIP: When buying, make sure the red-dyed kerosene is clear, like a blush wine, and not cloudy with pollutants.


Important Features of Modern Kerosene Heaters

The new generation of kerosene heaters contains updated safety and convenience features which make it a better indoor heat source than previous versions.

Battery-powered ignition, automatic shut-off, fuel gauges, lift-out fuel tanks, carrying handles, wrap-around protective metal grills—these and more new features make the modern kerosene heater a good alternative to other space heaters.

Sengoku Heat Mate, 23,000 BTU

The Sengoku Heat Mate is a kerosene heater with a Japanese design. Kerosene heaters are the primary method for home heating in Japan, so we may assume they know something about quality design.

This Sengoku heater has the common cylindrical fireplug profile with two exit port levels around the top section, along with a second protective cage over the top.

This unit heats up to about 900 square feet, delivering slightly less heating performance than other 23K BTU kerosene units.

There aren’t many frills here, but this Sengoku does offer a push-start ignition and carries an automatic shut-off in case of tipping.

The 1.9 gallon tank is a bit awkward to fill and delivers about 10 hours of heat. It’s fully portable, though it isn’t a lightweight model.

Sengoku is a well-established company, and this stripped-down model benefits from their design experience.

This is a good heater if you want a Japanese design and a basic portable indoor heater with few surprises.

The heater has automatic ignition and a one-touch shutoff switch for convenient operation. The fuel tank has an easy-to-read gauge and lifts out to be filled without having to move the entire heater. It has an automatic tip-over shutoff too, though the squat profile and wide base minimize that risk. Its 1.9-gallon tank provides from 8-12 hours of heat.

As an indoor heater, it isn’t made for rugged use. There are complaints about the lightweight construction of the ignition and the wick mechanisms. Also, though most users don’t report an issue with odor, some report a lingering smell.

Overall the Dyna-Glo WK24BK is a nice heater with a lot of safety and convenience features. It benefits from its maker’s expertise and will serve well for most indoor uses.

Pros

• Automatic ignition

The built-in 1.9-gallon tank is easy to fill, though you’ll need to move the whole unit outside to do it.

One tank offers up to 12 hours of heat, depending upon temperature conditions.

The heaters will operate on red-dyed kerosene, and users report only minor staining and a slight increase in the need for wick cleaning.

One possible issue is difficulty in changing the wick if you’re not mechanically inclined. Instructions are provided, but some find it a challenge.

Overall, this KeroWorld model is a nice portable heater without too many frills.

It’s easy to setup and operate, and comes with a nice 2-year warranty to get you through at least two seasons.
