Heating Methods Used in Space Heaters

Portable room heaters are highly energy efficient appliances to provide extra helping to the central heating system of the house. Heaters incorporate various heating methods to warm up the temperature. The three basic methods used in room heaters are radiation, convection and conduction.

Convection Heaters

Convection heating is by far the most common technique to heighten the room temperature in cold extremities. These machines usually feature a propane that blows hot air throughout the target spot, therefore, it works best when the occupants of the room are moving about. Convection heater models have a compact stature which makes them an apt fit for small rooms, cubicles, classrooms, study room and the likes. Although convection system won’t be adequately effective for large areas, it is still a budget-friendly means of maintaining a comfortable temperature in cozy places.


Radiation heating generates infrared waves that target the molecules of specific objects in a closed area, such as the skin and clothes of the occupants of the room. The aimed objects are warmed by the absorption of energy.


Conduction is the method of coursing the heat through a specific material. The heat is slowly emitted out of the coils placed within the heaters and circulates all over the room. This method is often used in spot heaters which can raise the temperature of only the objects or people within the device’s line of sight.

Types of Space Heaters

Although most room heaters rely on convection method, these heaters are light on pocket and capable to warming up small to medium rooms comfortably. Radiant heaters are particularly suitable for providing warmth and comfort to people too sensitive to cold. If you need a heater for just a few hours every day, the smarter decision would be to buy a highly energy efficient radiant heater that directly radiates the heat to the occupants of the room instead of the whole surrounding.

Convection Heaters

Convection heaters reach their peak efficiency when there are a number of people moving round and about the room. The best convection heaters can deliver up to 5000 BTUs (British Thermal Unit), plus, purchasing a unit won’t burn a hole in your pocket too. However, you might have to pay just a few hundred bucks more if you’re looking for a more advanced and versatile heating technology.

Ceramic Heaters

Ceramic plate heaters rely on convection heating method. These heaters are really fast, compact and generate plenty of warmth to keep the room temp comfortable during the cold season. The devices comprise of an oscillating fan that pushes the hot air away from heating elements and fills the entire surface space. These types of space heaters are the safest choice for indoor uses, specially if you’ve children in the house. It is because heating elements are neatly sheathed in ceramic plates. However, if you enjoy peaceful atmosphere in your living room, the noise of the fan could be a bit of a turn off for you. The heating might be quick but ceramic heaters can’t hold the heat for long after you switch the unit off.

Non-Electric Heaters

Most portable space heaters are electric. The less common non-electric counterparts come to rescue in remote rural areas where electricity is a scarce. The unit is fueled by either natural gas or kerosene and uses a propane to spread the hot air around the immediate surrounding spot.

Oil-filled Radiation Style Heaters

Oil filled units generally use the combination of convection and conduction method to spike the temperature. The large thermal core of the machines has an electrical element that heats the stored fuel in the heater’s fins. The cool air flows through the bottom and, passes over the fins, courses outward from the top and slowly fills the large room with hot air. The heating elements cycle on and off. There’s no fan to create grunting noises so, the operation is virtually noise-free. Slow heating and bulky design are the only negatives.

Radiant Heaters

Radiant style heaters primarily use wire element and quartz tubes as their heating elements. Wire element heaters are plug n play devices. When the unit is turned on, the electricity passes through a string of high-resistance wires which instantly turns super hot and rakes up the temperature as much as 1000 degree Fahrenheit. The heat is then evenly distributed throughout the surrounding area with the help of a fan or reflective backing.

Quartz element radiant heaters are relatively safer than the wire versions for indoor uses. In these machines, the wire work is securely positioned inside a quartz tube. The tube insulates the wire to boost the heating speed and energy efficiency. The air remains warm long after the hardware is shut off. Two more classifications of radiant heaters are:

Parabolic Heaters

Parabolic heaters use a ceramic core and rake up almost as much heat as a quartz element unit. The heating area is large enough, which is why it never glazes up too much to cause a fire situation.

Halogen Heaters

As evident from the name, this kind of room heaters features an energy saving halogen bulb to warm up the room environment. The bulb heats up quickly and emits heat waves that reflect on objects around.

Infrared Heaters

Infrared heaters are the most expensive and technologically advanced space heater models till date. These heaters house a heating chamber inside the unit to ensure maximum heat retention long after the device is turned off and accident prevention. Modern infrared heaters have a compact profile and come in various colours to complement the interior of your house. The operation is practically silent and additional features like touch-screen controls, timers, auto shut-off and energy saving mode options allows easy customization.

Micathermic Heaters

Micathermic heaters are a hybrid of radiant and convection heaters. A thin sheet of mica (which is a great conductor heat) and a bunch of radiant heating coils are the two chief hardware components of this unit. The heating coils heat up and channelize the energy to the mica sheet underneath. The heated mica draws the cool air from the surrounding and fills the gap with hot air instead. Micathermic heaters are two times faster than average oil based radiators and ceramic heaters. Moreover, the small stature of the heater is well-fitted for condominiums, classrooms and cubicles. On the downside, the temp of the room drops shortly after you shut off the device.

How to Choose the Best Space Heater

Right Heating Output Depending on the Room Size

In order to reap optimal benefit from your heater, make it a point to figure out the accurate heating output suitable for the room size where the machine will be installed. Heat output refers to the amount of heat generated from the unit, not the size of the casing. A lot of factors apart from room dimension such as climate, insulation, height of the ceiling etc influence the performance of the heater. While wattage is the measuring unit for electric heaters, BTU is used for non-electric version.

Multiply the BTUs by 3.41 to convert it to watts. For a well-insulated space, it takes about 10 watts to increase the temp by 10 degrees per square foot. Measure the dimension of the room to calculate the total square footage and multiply it by 10 degrees to determine the required heat output. Note that this is just a rough estimation. The wattage will have to be increased if the atmosphere is extremely cold or the ceiling is over 8 feet high.

Heater Size

Nothing’s worse than an oversized heater. It not only occupies a big share of the important space of the house but also increases fire hazard. Wall-mounted ceramic heaters are an apt choice for condos, small bedrooms, workshops and study rooms. Garage heaters are usually larger in stature and deliver unflinching performance under the most grinding conditions. The units are thermostatically controlled and have a high resistance to humidity.

Vented V/s Unvented Heaters

Vented heaters are the safest kind of heaters for indoor uses. They are designed to be set permanently nearby a window or an outside wall. The flue gas vent needs to be fitted right through a ceiling or the outside wall. Vented heaters either come with sealed combustion units or 100% outdoor air units. The reason why vented heaters are much safer than their unvented version is because they do not draw hot air from the room which in turns helps maintaining the quality of air inside the closed space. On the other hand, unvented combustion heaters produce highly inflammable substances like carbon monoxide and nitrogen oxides during the heating process.


Portability is another crucial point to out under assessment while shopping for the best space heater. Quality models come with built-in wheels that make relocating the unit a breeze. If you’re looking for an ultra-light model, make sure there’s a heat protective handle on the casing.lightweight, compact heaters are easy to lift, and therefore, installing it on the wall won’t cause a crack in your bone.


This is an important aspect to pay attention to if you’re planning to buy a fan forced convection heater. The option to oscillate the appliance side to side helps you circulate the heat more quickly and thoroughly over a large surface area.

Heat Settings

Having the option to adjust the heat output with the help of an in-built thermostat is a welcoming feature in any room heater. Many top end models offer multiple heat settings with a timer so that the machine can be turned on or off without manual effort.

The Looks

The advances in space heater manufacturing technology aren’t restricted to the features. With a massive leap in the sales over the last few years, manufacturers have been inspired to come up with unique and stylish designs to blend in with the décor of the room.muh attention have been given to the safety and functionality of the combustibles. Many top-of-the-line infrared heater models replicate fireplaces, these aesthetically stunning designs add a nice, vintage feel to the living rooms.

Hush Hush Operation

Fan forced ceramic heaters can be very noisy, due to the constant movement of the fan. Nobody wants this kind of disturbance while enjoying a movie or sipping on hot chocolate on a cold wintry evening. Infrared and Micathermic heaters yield plenty heat in a pin-drop silent mode.

Space Heater Safety Considerations

Apart from the general safety instructions provided by the manufacturer, there are some other safety guidelines to be followed between the lines in order to prevent potential accidents:

  • Make sure the model you’re eyeing for have gone through several fire safety tests. Any safety certification such as the UL hallmark from Underwriters Laboratories or the equivalent ETL or CSA certification bear the testimony of a heater’s safety arrangements.
  • Have your vented heater inspected by a professional before installing. If the quality of venting isn’t up to the mark, the air inside the room might be introduced to an alarming level of carbon monoxide which a highly toxic gas. Another possible cause behind excess CO production could be wrong positioning of the device or any other installation error.
  • If the space heater doesn’t come with GCFI (Ground Fault Circuit Interrupter) plug, do not commit the inexcusable mistake of setting the unit around water or it may result in electrocution.
  • Use only approved fuel for oil-based radiant heaters. You will get a fair idea of recommended heat transfer fluids from the manufacturer’s guidelines. Store the oil in a suitable container and never overfill the tank.
  • If using an extension cord is necessary for plugging in your electric heater, stick to the manufacturer’s instruction regarding the following as most electric heaters aren’t suitable to be used with an extension cord.
  • It’s best to spend slightly more for a machine that offers automatic shut-off option to guarantee optimum safety of the house as well as the housemates. Overheating is a stand-alone cause for emergency situations in thousands of apartments every year. Devices equipped with smart sensors automatically shuts off the unit whenever necessary, in case you forget to turn it off on your own.
  • Place the heater on a levelled surface, at a safe distance from water and ignitable elements. Put it at a high altitude, at least a few feet away from the reach of pets and kids, furniture and curtains.
  • Get the heater tested every month, specially the cord and install a smoke alarm in the house or wherever you’ve installed the device.

Summing up the Article

Portable room heaters save energy by boosting the temperature surrounding the occupied room instead of heating the entire apartment. The new and improved, thermostatically controlled models prevent energy waste and overheating. While purchasing a heater, make it a point to choose a product that offers all the current safety features in order to avoid nightmare scenarios in future. Take extra precautions if you have children or pets in your house, place the heater at a space distance from their reach. Vented heating units are the safest heaters to be used inside home as they expel the combustion gases directly through the ceiling.
