Best Forced Air Kerosene Heater Buying Guide
With the reviews done, let’s turn to the buying process. How do you choose the right forced air kerosene heater? Consider the following factors;
What is a Kerosene Heater?
A kerosene heater is simply a heater that operates using kerosene as its fuel. The heaters are mostly used to supplement primary sources of heat or in times of emergency such as when there’s a power outage.
Aside from the lower cost, kerosene is preferred over other types of fuels because of the low volatility. Also, kerosene is safer as it’s hard to ignite and has 99% combustion efficiency.
How Does Kerosene Heating Work?
The working mechanism of kerosene heaters is very simple. The heaters have a circular wick in the center. The wick hangs over a tank filled with kerosene, with the bottom end of the wick dipping into the tank. When the tank has kerosene, a portion of the wick ends up in the fuel and draws up some of the kerosene through capillary action.
To start the heating process, all you have to do is light the top end of the kerosene-drenched wick. When ignited, kerosene instantaneously becomes a gas. Burning of the gas generates heat. The greater the surface area of the wick exposed, the bigger the flame and amount of heat produced.
What is a Forced-Air Kerosene Heater?
In a typical kerosene heater, the heat generated is moved throughout the intended space through radiation and natural convection. Radiation is where heat travels as electromagnetic waves, heating objects on its path. Convection, meanwhile, is where warm air rises as cold air takes its place closer to the ground or floor.
Unsurprisingly, these two natural processes aren’t always sufficient. Natural convection, for instance, is heavily dependent on movement in the air (wind). On a still day, the air would move around, yes, but very slowly. Radiation, on the other hand, is ineffective as radiant heat becomes colder and colder the further away you move from the heat source.
To offset these issues, modern kerosene heaters incorporate a fan to boost the air blowing process. And these fans are often powered by electricity.
Types of Forced-air Kerosene Heaters
There are two broad categories of forced-air kerosene heaters – convective and radiant. The difference is in how the heat is moved.
1. Convective heaters
Also the more common type, convective kerosene heaters are primarily cylindrical in shape in order to disperse heat in a 360-degree fashion – upwards and downwards. They are the better option for large areas and can even be used to heat multiple areas simultaneously.
Most convective kerosene heaters have fixed fuel tanks. To refill the tank, you need to move the heater itself and use the siphon pump for refilling.
Convective heaters are generally larger than radiant heaters. In addition, they also have a higher energy output and consume more fuel.
2. Radiant heaters
Radiant forced air kerosene heaters, meanwhile, mostly have a rectangular shape and are designed for smaller spaces. They work by reflecting heat from the burner element into the open space. They have a reflector for this purpose (convective heaters don’t). The reflector directs the heat towards people or objects in the room.
Most radiant heaters come with a removable fuel tank. This means that you can take out the tank and refill it without moving the heater.
Advantages of Forced air Kerosene Heaters
Forced-air heating is used even in whole-home furnaces to ensure faster, more even distribution of heat throughout the house. Some of the key benefits of these heaters include;
1. Instant heat
When it’s freezing cold, such as in the middle of winter, you may not want to wait a few minutes for the room to get warm. Unfortunately, heaters that depend exclusively on natural convection and radiation can be slow, especially on still days. A forced air heater solves this problem by making use of electric-powered fans to ensure faster heat dispersion. Within seconds, the entire space will be warm.
2. Even heat distribution
Aside from dispersing heat faster, fans also help distribute the heat more evenly. Take an example of convective heaters. Convection is defined as the process where warm heat rises and cold air takes up the vacated space closer to the floor/ground. But, who needs warm heat up there at the ceiling? We need the heat most at the lower half of the room, right? Fans can help blow the heat around so that every area of the room is uniformly heated, ensuring optimal comfort.
3. Higher energy efficiency
Finally, forced air heating systems have been found to be very energy efficient. One study found that forced air furnaces have an Annual Fuel Utilization Efficiency (AFUE) value of 78%. AFUE is the amount of heat a heating system delivers relative to the amount of fuel consumed. Going by the findings of the study, forced air heaters have a much higher AFUE value than fan-free models.
Considerations When Choosing Kerosene Forced Air Heaters
There are several factors to consider when choosing a forced air kerosene heater. These include;
The heater type
We’ve discussed the two main types of heaters in this category (radiant and convective). Which of the two best suits you application? In general, choose convective heater for larger applications such as whole room heating. Radiant heaters, on the other hand, are best for spot heating.
Size and capacity
Kerosene heaters come in different BTU sizes. Some are rated close to 200,000 BTU while others are at 50,000 BTU or less. When making the decision, think about application. For whole room heating, you need more heating power, thus more BTUs. Spot heating, however, doesn’t need so much heating power. Always check the product label to learn how much space the heater can heat.
Do you intend to keep the heater in one place for its entire life or are you shopping for a heater than you can move from one application to another? If you’re looking for the former, then a larger, heavier model with a bigger tank would be ideal. For the latter, however, a smaller, more portable heater would be needed.
In the end, you also must think about the cost of acquiring and running the heater. In general, smaller heaters are less expensive. Ones without fans are also less expensive than fanned models. But, again, keep the application in mind. Sometimes, a larger heater with a fan might be better long-term. Forced air kerosene-heater prices range from $250 to over $500.
Environmentally-friendly components, thermostats, and timers are some of the extras to keep an eye out for. Thermostats allow for closer control of indoor climate while timers are an invaluable convenience feature that let you program your heater in advance. All these features boost the heating experience.
Kerosene Heater Safety
Like any other heating appliance, kerosene heaters aren’t 100% safe. There is a genuine risk of burns and carbon monoxide poisoning. In forced-air models that use electricity, the risk of electrocution is also present. The following safety tips are recommended;
- Keep track of the fuel gauge: A fuel gauge helps prevent overfilling or unnecessary refilling. Also, ensure that the heater comes with a siphon pump to prevent accidental fuel spills.
- Check for a safety shutoff: The heater should have an automatic shut-off switch that snuffs off the flame if the heater tips over.
- Professional certifications: Check for approval or certification by a recognized professional agency such as the Underwriters Laboratory (UL) or Factory Manual (FM).
- Use Grade K-1 paraffin: Grade K-1 kerosene is clear as water. Yellow or colored kerosene is not pure and may damage the unit as well as cause excess smoke and emit strange odours. Learn ways of stopping kerosene heater from smelling here as well as stopping heater from smoking.
- Use kerosene fuel only: Never use any other fuels such as gasoline, camp stove fuel, or other flammable liquids in the heater unless the manufacturer permits it.
- Ensure sufficient ventilation: Kerosene heaters require plenty of oxygen to burn completely. Poorly ventilated rooms may result in incomplete burning, creating the poisonous carbon monoxide (CO) gas.
- Ensure sufficient clearance: The heater must be placed at least three feet away from flammable items such as window curtains and furniture. Make sure the heater isn’t blocking a path or walkway.
- Don’t get burned: Kerosene heater surfaces get very hot. To avoid burns, keep the heater out of the reach of young children and pets. Also, don’t touch the surfaces with your bare hands. When refilling, turn it off, allow the surfaces to cool, and carry the unit outside.
Forced-air kerosene heaters are a great supplemental heat source especially in areas with frequent power outages. The heaters generate strong heat that moves around the room quickly thanks to fan-aided convection and radiation. When shopping for one, to consider factors such as size (in BTU), portability, noise, and digital controls. Also, make sure you find a safe heater that’s certified by a recognized agency such as the Underwriter’s Laboratory (UL) or the CSA.
