The Best Electric Heaters: Finding an Energy Efficient Option

When the temperatures start to drop outside, an electric heater can be a great way to keep your home warm without running up your energy bill. But with so many electric heaters on the market, it can be hard to know which one is the best and most energy efficient one for your needs. To help you out, we’ve put together a guide to the best electric heaters, and what makes them energy efficient. Keep reading to find out more.

Best electric heater

When looking for an energy-efficient electric heater, the oil-filled heater is the best option. They use a heating element to warm oil, which is then circulated by a built-in fan to distribute heat throughout the room. Convector heaters are also relatively energy efficient as they heat the air directly, which is then circulated by natural convection. Halogen heaters and infrared heaters are the least energy efficient options.

Radiant Heaters

Radiant heaters are among the most efficient electric heaters out there. They directly heat up the objects and people in the room, rather than just heating up the air, meaning you don’t have to wait for the heat to reach you.

Radiant heaters are best for energy efficiency because they generate heat directly from the source, such as infrared radiation. This type of heating is much more efficient than convection heating, which requires air to be heated before it can be transferred to other objects. Radiant heaters also distribute heat more evenly, meaning less energy is wasted on heating unused areas.

They’re also completely silent, so you don’t have to worry about any annoying noise. The best radiant heaters are energy efficient, and have features like adjustable thermostats and safety shut-offs.

Convection Heaters

Convection heaters are another great option when it comes to energy efficiency. These heaters work by circulating hot air throughout the room, and they’re great for larger spaces. When shopping for a convection heater, look for one with adjustable thermostats and a timer, as these features can help you save on energy costs.

Convection heaters are best for energy efficiency because they use air currents to circulate warm air throughout a room. This type of heating is much more efficient than traditional methods of heating, as it doesn’t require a large amount of energy to maintain a consistent temperature. Additionally, convection heaters don’t generate any drafts, so they are less likely to cause cold spots in a room.

Infrared Heaters

 Infrared heaters operate by heating up objects in the room, rather than the air. They’re a great option for energy efficiency, as they don’t waste energy heating up the air. They’re also very quiet, so you don’t have to worry about any annoying noise. The best infrared heaters come with adjustable thermostats, timers, and other features that can help you save energy.

Infrared heaters are highly efficient because they heat objects in the room rather than the air. This means that the heat is used more effectively and less energy is wasted. Additionally, infrared heaters operate at lower temperatures than traditional heating systems, so less energy is needed to reach a comfortable temperature.

Oil-Filled Heaters

Oil-filled heaters are a great option when it comes to energy efficiency. They operate by heating up a reservoir of oil, which then radiates heat. This means they’re great for keeping a room warm for long periods of time, without wasting energy. The best oil-filled heaters come with adjustable thermostats, timers, and other features that can help you save energy.

Oil filled heaters are energy efficient because they retain heat for a long period of time. Oil takes longer to heat up than air or water, but it also stays warm for a longer period of time. This means that the heater does not have to work as hard to keep the room warm, resulting in less energy being used over time. Oil filled heaters are also quieter than other types of heaters, making them ideal for bedrooms and other quiet areas.

Which is the most energy efficient electric heater?

Out of the electric heaters listed, the most energy efficient option would likely be the oil-filled heater. This is because oil-filled heaters use a heating element to warm oil, which is then circulated to distribute heat throughout the room. Because the oil retains heat well, it continues to radiate warmth even after the heating element has been turned off, resulting in more consistent and efficient heating.

The convector heater is also relatively energy efficient as it heats the air directly, which is then circulated by natural convection, which is less energy intensive than using a fan, which is used by the fan heater. The halogen heater and infrared heater are the least energy efficient options as they heat the air directly and heats objects and people in the room, which causes a lot of heat loss.

Energy efficiency factors to consider with electric heaters

There are several other factors to consider when evaluating the energy efficiency of electric heaters:

  1. Size of the heater: Larger heaters are generally more energy efficient than smaller ones, as they can heat a room more quickly and with less energy.
  2. Insulation: Insulation in a room can greatly affect the energy efficiency of an electric heater. A room with good insulation will retain heat better, allowing the heater to use less energy to maintain a comfortable temperature.
  3. Thermostat: Look for a heater that comes with a built-in thermostat or one that can be controlled with a separate thermostat. This allows you to set the temperature to your desired level, and the heater will automatically turn off or down when the temperature is reached, saving energy.
  4. Timer: Some heaters come with a built-in timer, which allows you to set the heater to turn on and off at specific times. This feature is useful for saving energy when the room is not in use.
  5. Energy rating: Look for heaters that have a high energy efficiency rating, such as those that have been certified by Energy Star.
  6. Safety features: Look for heaters that have safety features such as overheat protection, tip-over switch and safety shut-off valve to ensure that the heater is safe to use.
  7. Maintenance: Regularly maintaining the heater by cleaning it, and keeping the filters clean, can also help improve its energy efficiency.
  8. Room size and usage: Consider the size of the room, the number of people and pets, and how often the room is used. This will give you a good idea of how much heat is needed, and what size and type of heater will be most energy-efficient for your needs.

Summary

Electric heaters come in different types and models, each of which has its own level of energy efficiency. Among the most energy-efficient electric heaters are oil-filled heaters and convector heaters, which heat the air directly and are less energy intensive, and fan heaters.

Halogen heaters and infrared heaters are the least energy efficient options. Other considerations when evaluating energy efficiency of electric heaters include size, insulation, thermostat, timer, energy rating, safety features, maintenance, and room size and usage.
