Different Types of Portable Heaters for Large Rooms

Infrared Heaters

Infrared heaters produce infrared rays that heat inanimate objects in a room, including furniture, walls, and even the floor. Once the inanimate objects get heated, they start releasing the warmth into the air in the room. Thus, the air in the living zone of a room gets heated continuously from the inanimate objects.

The greatest benefit of using infrared heaters is that one gets to warm the house fast and at manageable energy costs. Infrared heaters are quite effective in providing the required warmth in large spaces such as living rooms and offices.

Ceramic Heaters

Ceramic heaters have a heating element that is made from clay material. The heating element is directly heated by an electric current. As the element gets hot, it in turn heats the air that passes near it. Thus, ceramic heaters operate using the convective mode of heat transfer.

Naturally, warm air tends to rise fast and get replaced by cold drafts of air. When you place your ceramic heater anywhere in the house on the floor, it heats warm air that comes into contact with it. The heated warm air then rises and transfers with its heat to other parts of the house. The process repeats as long as the heater is on.

Because this heater uses convectional current to transfer the heat, it requires to be placed near openings such as windows for it to provide adequate heat in the house.

Oil-Filled Heaters

Oil-filled heaters operate using diathermic oil that is directly heated by an electric current. Once the oil gets hot, it starts to release its heat to the surrounding atmosphere. Therefore, diathermic oil acts as a form of energy reservoir. It stores the energy transferred by the electric current and then releases it slowly to create a cozy environment.

Some oil-filled heaters have inbuilt fans to accelerate the movement of warm air from the vents of the heater to the outside environment. Such heaters tend to provide warmth to large spaces within short times.

Propane Heaters

Propane heaters are designed to be used in outdoor environments in general. They comprise of a special plug that is used to ignite the propane. The propane burns in a controlled environment that has an element. The porcelain element directs the burning propane to release hot air that warms the environment via convection currents.

Propane burning heaters are bulkier than electric and oil-filled ones because they carry propane tanks and other accessories. They are ideal for use in areas where it is difficult to connect to electric power.

Kerosene burning heaters can be used for indoor and outdoor heating. They burn kerosene to provide warm convection currents that in turn provide warmth to the environment.

Factors to Consider when Buying Heaters for Large Rooms

Heating Capacity

best portable heaters for large rooms in a modern living room

The heat capacity of a heater refers to the area that it can cover. There are two ways of assessing the heating capacity of a heater: using the British Thermal Unit (BTU) of the wattage.

To get the heating capacity of your heater in terms of BTU, divide the value by 40. Therefore, if a heater has an indicated BTU value of 24,000; it means that it can heat an area that is 800 square feet.

In terms of wattage, 10 watts are enough to provide heat for one square foot space. If your heater consumes 1,500w at most, then it means that it can heat an area that is 150 square feet large. When the heater operates on the 750w, then it will provide enough heat to warm air in an area that is 75 square feet large.

Noise Level

Electric heaters emit noise when operating. However, the level of the noise varies among brands and the general types of heaters. Heaters that have inbuilt fans are noisier than those without fans. Thus, the cost of getting a heater which provides heating fast and effectively is a noisy room.

The noise becomes pronounced in silent environments like bedrooms at night. Therefore, when choosing a heater, consider its noise level and the place where you would like to use it.

Energy Efficiency

The energy efficiency level of your heater determines the heating energy costs. Highly efficient heaters spend less energy to warm space than less efficient ones. Because, heating energy costs can be quite significant, depending on the size of your house and the prevailing weather conditions, it is logical to go for highly efficient heaters.

There is no industry-standard method of determining the efficiency of portable heaters. However, you can achieve efficiency in your home heating operations by choosing heaters that have certain favorable features.

Heaters that come with advanced control settings, inbuilt timers and thermostats can provide more efficient methods of heating the home than those which lack such features. You can use the controls to minimize instances of overheating and ensure that the heater works only when it is required to do so.

Additionally, go for heaters that are suitable for your spaces. If you have large rooms with high ceilings, then it makes sense to buy heaters that can warm such places. Going for low-capacity heaters may decrease the level of efficiency and increase heating costs.

Portable Space Heater Safety Checklist

  • Always switch off and unplug your heater when not using it. This applies to at night when you are about to sleep or in the evening when leaving the office.
  • Keep portable heaters away from spaces that are commonly used by people at home or in the office. This practice minimizes the chances of your heater getting knocked by a person passing by.
  • Do not keep heaters under tables or desks. This measure prevents accidents that can occur when your visitor at home knock the heater under the table. Also, your legs may knock off the heater if it is placed under the desk at the office.
  • Ensure that your heater is placed far away from easily combustible materials in the house or office. Some of the highly combustible materials include all types of fabric, plastic things, and papers.
  • Go for heaters that have an over-heat protection functionality. Such heaters automatically go off when the temperature rises rapidly. This protects the components of the heater from getting damaged as a result of overheating.
  • Choose heaters that bear the mark of nationally recognized safety standards such as UL and others. Heaters with such standardization marks have undergone and passed defined safety tests.
  • It is better to use heaters that have tip-over protection than those which do not have it. The tip-over protection feature helps to prevent accidents when the heater is knocked. The heater automatically goes off when it suddenly rotates after getting knocked.
  • Ensure that children and pets do not play around the heater. Although standard heaters come with a cool-to-touch feature, it is advisable to keep them as far away from kids and pets as possible. The surfaces of the heaters still become warm to considerable levels which may pose a danger to children.
  • Regularly check all the parts of your heater to ensure that they are intact. This applies to certain easily observable parts including switches and cords.
  • Follow all the technical instructions that are provided by the manufacturer. The instructions may be about installing, operating, and maintaining the heater.

Tips for Positioning Space Heaters

Installing the best portable heaters for large rooms on a wallKeep your heater away from moist places

Electric heaters can easily get damaged by water. Therefore, ensure that you position the heater away from places that are normally wet such as bathrooms. There are special heaters that are made to be used in bathrooms. Such heaters have all the protective features required to keep them functional even when they get wet.

Also, keep your heater away from places where fluids may spill. Kitchens are very notorious for spills. Therefore, to get the best service from your heater, position it away from kitchens, bathrooms, and any other place where fluids may be easily spilled.

Position the heater away from the wall

Keep your heater as far away from the wall as possible as a safety measure. Walls may have hanging curtains and other highly combustible materials. Because heaters normally get hot during operation, it is safe to ensure that they are not anywhere near curtains that do hang down walls.

Furthermore, heaters require enough space for them to operate effectively. Heaters that have inbuilt fans require enough space for the fan to push out the warmed air. Even fans that do not have inbuilt heaters do require enough space to function effectively.

Away from children and pets

Wall-mountable heaters are safer than the stand-alone types because they can be positioned at heights that both children and pets cannot beat. When using stand-alone electric heaters, it is advisable to place them in specially-designated places. Although the heaters may have a cool-to-touch feature, their surfaces do get very hot after a long time. This may pose a real danger to anyone at home or even in the office.

Setting up a special buffer zone for your heater at home or office will also minimize the risk of people knocking the heater over while they are passing or working.

Position your heater in enclosed rooms

Electric heaters are designed to provide supplemental heat. Ideally, they should be used when they are needed most. The best way to achieve this objective is to ensure that you use your heater in a room that is enclosed. Also, position the heater where it is needed most to maximize its utility.

Wrap Up

Since a space heater is used to supplement the traditional unit, it’s important to understand your needs before choosing the best portable heaters for large rooms.

If you don’t want your electricity bills to skyrocket, make sure you select the right BTU levels. If better, seal any leaks and insulate the rooms to prevent heat loss.

I hope this space heater review was insightful and you were able to choose the best space heater for large room depending on your needs
