The best heater for uninsulated garage will provide supplemental heating will increase your energy bills. These types of space heaters are either energy-star rated or have energy-saving features.

Electric space heaters come in various shapes and sizes, are priced differently, and use different fuels. Some can use electricity while others can use propane, natural gas, or kerosene.

In this portable heater review, I’ve included different types of energy-efficient garage heaters to help you beat the cold in winter.

Are Space Heaters More Efficient Than Central Heating?

Whether you need to heat your home constantly or occasionally, efficiency is important. Using the most energy-efficient portable heater will help to reduce your energy expenses. There are primarily two ways of heating a home: using a central heating system or a standalone space heater.

Whether you use a space heater as a source of secondary or primary heat in the home, you may have to consider whether doing any of this is more efficient than using a central heating system.

The answer to the question of whether space heaters are more efficient than central heating systems varies with the conditions on hand. If you would like to heat a small room in your home, then it would be wise to use a space heater and not the central heating system.

A space heater is more efficient than a central heating system when you need to heat small spaces because it has been designed for such tasks. Your central heating system, which is part of the HVAC network in the house, has been made to provide heating in multiple rooms. Therefore, if you would like to heat one room, like the living room or bedroom, then it is better to use a space heater. This will ensure efficient utilization of energy for heating.

Furthermore, space heaters may be more efficient than central heating systems because one can easily control them. They come in a variety of shapes, sizes, and technical features. Moreover, the level of efficiency of space heaters varies with brands and sizes.

When using a space heater, you can conveniently adjust its performance to ensure efficient utilization of energy for heating. For many heaters, it is possible to change the heating capacity and other attributes of the devices. Such changes can have a far-reaching impact on the level of efficiency of the heater. Such a level of customization is not found in central heating systems.

However, central heating systems are more efficient than space heaters when compare to the two using energy per heat output. Because space heaters have been designed to provide heat in entire houses, they are more effective than space heaters. It would be inefficient and impractical to purchase and use multiple space heaters in all the rooms in a home.

Therefore, if you need to heat the entire house, always use the central heating system. However, if you intend to heat a few rooms one at a time, then go for space heaters.

How to Select the Best Heater for Uninsulated Garage

Selecting the best portable heater energy efficient will minimize your heating expenses. However, getting the right heater is difficult because of the large number of brands with different features that are currently available on the market.

Primarily, you need to look out for heaters that have appropriate features. Here are a few things that you should bear in mind to select an energy-efficient space heater.

  • The auto or eco mode. Heaters that have this mode are more efficient than those which lack it. The auto or eco mode helps heaters to maintain the temperature according to the heating requirements of a room at any given time. Go for space heaters that have this feature to avoid wasting money on unnecessary heating.
  • Multiple heat settings. Although many heaters have low and high heat settings, some have an additional medium heating setting. Space heaters with three settings can be used to warm houses more efficiently than those with only two settings. You can use the three settings to adjust the performance of the heater according to the changing needs of your home and personal preferences.
  • Programmable thermostat. The function of a programmable thermostat in a space heater is to maintain the temperature within a specified range. When the temperature falls below the selected value, the thermostat automatically triggers the heater to continue working. The heater then stops heating the air when the ideal temperature is reached. This cycle continues as long as the heater is operating.
  • Programmable timers. Programmable timers help you to determine the period during which heaters operate. You can schedule your heater to automatically switch off after a few hours when you are out of the room. It is easy to use a programmable timer to schedule the automatic switching off of a heater when you are going to bed. Thus, the programmable timer helps to prevent wastage of energy for unnecessary heating.

How to Use Space Heaters Efficiently

You can have low energy heating costs by choosing the right kind of heater and using it efficiently. Here are a few tips to help you minimize the total energy heating costs when using space heaters at home.

Use your Portable Heater Only when It’s necessary

Space heaters are designed to heat small areas of the house. Moreover, they have various control features that you can use to determine how they work. To ensure that you achieve efficiency when heating the home, only use your heater when it is needed. You can warm the living room or sitting room when there is a need for doing so. Avoid warming areas of the house that are not occupied by people regularly, including the basement.

Remember to switch off your heater when you get outside the room. Doing this will help you avoid wasting electric energy heating a room that is not occupied. Similarly, remember to switch off the heater during the night when you go to bed. Although heaters have great safety features, it is always recommended that you switch them off during the night when you go to bed. Doing so helps to prevent the occurrence of accidents and minimizes the use of electric energy for heating the home.

Consider Heaters with Inbuilt Thermostats and Timers

It is easier to efficiently heat your home when using heaters that have inbuilt thermostats and timers than those which do not have these features.

  • Thermostats help to regulate the temperature of the heater by reading ambient temperature changes and adjusting the heating performance of your device accordingly.
  • Timers can be used to set the maximum period during which a heater should be on.

If your heater has these features, ensure that you use them to your advantage. Digital thermostats are quite accurate in reading the ambient temperature. Use them to prevent your heater from generating unnecessary heat. Also, use the timer to ensure that the heater does not operate when no one needs it to be on.

Use the Heater as a Secondary Source of Heat

A space heater is made to be used to supplement the central heating system. The heater serves as a portable, and effective source of additional heat in rooms and other spaces at home. Typically, heaters are either moved around or installed in rooms that are mostly occupied, including bedrooms and living rooms.

When using your space heater as a secondary source of heat in the home, ensure that you switch it on or off when it is necessary. This may be during particularly cold periods of the year or the day.

Take Advantage of the Heating Method Used by your Heater

Heaters use either the radiant or convection methods of heating. Radiant heaters are effective in quickly warming rooms because they pass infrared radiation to animate and inanimate objects in rooms. Thus, they can be used in small spaces that are fully packed to rapidly create and maintain a cozy environment.

Convection heaters usually have fans that are used to distribute the heated air across large spaces. Utilize their mode of operation to effectively heat large spaces without losing track of your heating expenses.
