Heater Types

Electric powered portable heaters

They are deemed to be very energy proficient as they do not lose heat via the combustion. They produce warmth that radiates within the particular room. This keeps a room comfortable and warmer for long. Types of electric portable heaters include:

Lasko Ceramic HeaterCeramic heaters: these are convection heaters designed with a ceramic disc heating element and a fan that dispenses heated air efficiently and evenly. The ceramic disc is usually concealed inside the heater’s body to minimize the risk of a fire in case the heater tips over. Most ceramic heaters remain cool even when on to reduce the risk of getting burned. Therefore, they are deemed safe and are the ideal choice for a children’s room or a place where pets move around.


Bionaire Convection HeaterConvection heaters: these are very energy efficient and are ideal for heating large rooms like living rooms for a shorter period of time. Convection heaters use permanently sealed heat transfer liquids like oil with an electric heating component. These liquids are safe from leakages, store and distribute heat using natural air circulation within the room and rarely require refilling. Some heaters are designed with fans for better air circulation. These types of indoor portable heaters are ideal for sealed off rooms without open doors.


Optimus Radiant HeaterRadiant heaters: these are also referred to as reflective heaters that produce immediate heat through directing infrared heat rays to warm up room objects. They are ideal for individuals who seek heat for a short period of time. They offer a number of advantages as compared to the convection heaters that include: silent operations, moving parts, reduced energy costs and non-dependency on air motion.

Operational Cost

The cost of operating your indoor heater depends on a number of factors: home insulation, efficiency of the main furnace and size of room to be heated. The manufacturer will most likely include ratings of the unit you are considering. You definitely don’t want to buy a heater that is too big for the room as it can over heat.

You can use this formula to estimate the cost of operating the unit:

Cost = (Wattage divided by 1000) X Average cost of electricity per kilowatt hour X Hours used

Safety Features

Choose only newer models that have been approved by Underwriters Laboratory (UL). Avoid using extension cords since most do not handle the power of the heater. If possible, choose a thermostatically controlled heater since they do not waste energy by over heating a room.

A tip over switch is recommended because this feature turns the unit off if turned over. Another safety feature is over heat protection which turns the unit off when temperature is too high.
