Introduction to the Benefits of an Efficient Electric Heater

Heating your home efficiently, cost effectively and safely is a priority for many people. An efficient electric heater can provide all of these benefits and more. Electric heaters are becoming an increasingly popular way to heat any space, from a single room to an entire house. They are energy-efficient, easy to use, and come in a variety of styles and sizes to fit any need. With an efficient electric heater, you will have reliable heating with no need for costly maintenance or repairs.

Efficient electric heaters typically utilize two distinct forms of heating technology: convection and radiant heat. Convection works by circulating the air around the room, while radiant heat is produced directly from the heater itself. Each type has its own advantages – convection is better at evenly distributing heat throughout the room while radiant heat provides intense warmth in a localized area – so it’s important to consider which type best suits your needs before making a purchase.

Aside from their heating capabilities, most efficient electric heater models also feature additional features like adjustable thermostats and timer functions that allow you to program when you want your heater to turn on or off. This ensures that you get the exact temperature you desire without having to constantly adjust the settings manually. Additionally, some models have built-in safety features such as overheat protection and tip-over shutoff systems – both of which are designed to keep you safe when using your electric heater.

Overall, an efficient electric heater can be an invaluable addition to any home’s heating system and provide reliable warmth at a fraction of the cost of traditional heating methods like gas furnaces or wood stoves. With so many options available on the market today, finding one that meets all your needs should be relatively straightforward.

The Dr. Infrared Heater’s good looks won us over the moment we opened the box. It has a solid wood case that would look fantastic in any part of the house. Since the Dr. Infrared is a 1,500-watt heater, we tested it in a 156-square-foot (13 x 12-foot) room.

Incredibly, the heater barely made a sound when it was on; all you could hear was a faint hum. We increased the thermostat by 5 degrees Fahrenheit, turned the space heater up to its highest setting, and shut the door to see how long it would take to get the room to a comfortable temperature. We saw a rise in temperature after only 15 minutes; after 33 minutes, the room had warmed by 10 degrees Fahrenheit.

We then checked over the rest of the options on the space heater. We measured how much heat was generated at low and eco settings and tried the timed function. The heater may be controlled both by its in-unit controls and the supplied remote.

We also tried out the standby setting, which lights up a little indicator light to let the user know the heater is plugged in but not producing any heat. We were unimpressed by this function, as the light stays on even after the heater is turned off in standby mode. Liked that it had a timer that let us set it to go on for up to 12 hours at a time. Successfully turned off the heater at the given time, the timer proved to be a useful device.

The Dr. Infrared’s thermostat control was our favorite feature. The thermostatic heater would turn on and off automatically to maintain the room at the chosen temperature. Finally, we pushed the heater over, and it promptly shut off, a function included on many electric space heaters to avoid fires.

Since 2013, we’ve advocated for the Lasko 754200 Ceramic Heater as one of the best and most cost-effective heaters in its class. It’s smaller and lighter than the other fan heaters we tested, yet it heats up far quicker. Its size is comparable to that of a loaf of bread. The space heater emits a concentrated stream of hot air, warming the area in front of it. This is fine, but we much like the wide, room-filling heat of the Vornado models.

Even though this Lasko heater has trouble keeping up in larger rooms, it is ideal for swiftly warming a home office or a small bedroom. Many members of the Wirecutter team have owned the 754200 for multiple winters with few issues, and it has received mostly excellent feedback from owners for years. It’s not the most aesthetically pleasing choice, but it has overheat protection in case something goes wrong. It lacks an automatic tip-over kill switch, which is featured in our top pick.

5. De’Longhi Mica Panel Heater HMP1500

No products found.

Micathermic heaters warm the space by emitting both visible light and infrared radiation. This De’Longhi model with 1,500 watts of power, when set to high, warmed our 156 square foot test room by 5 degrees Fahrenheit in just 18 minutes. With its slim panel design, radiant heat is only emitted from the front of the heater, keeping the sides and back comfortably cool. This small and compact design not only saves on physical space, but also runs quietly.

Attaching the caster wheels was a breeze using the accompanying bottom knobs that could be twisted by hand (no tools necessary). Installing this heater on a wall will require the use of drywall anchors, which are not included. We were able to fine-tune the heater’s temperature and ventilation by turning the dials on each side. When we knocked it over, it automatically shut off. The front panel gets quite warm, so it’s not ideal for families with young children unless it’s mounted high on a wall and out of reach.

Factors to Think About to Buy the Best Most Efficient Electric Heaters

Electric space heaters are more common than those that burn kerosene or propane because of the problems associated with the odors and the dangers of the fuels. Even if you limit yourself to electric heaters, you’ll still have a huge selection from which to pick. Numerous critical factors need to be considered.


Space heaters of several forms can be examined when the process of creating heat has been studied. Most electric space heaters use convection (a fan blowing over a heating element) to warm the air, while radiant and micathermic heaters are also available.


One of the earliest forms of electric space heaters were oil-filled radiators. They are bulky because they are made for moderate to large rooms, but they usually include wheels so you can roll them around easily. They generate some heat by radiation but focus mostly on warming the air around them.


The most common kind are ceramic heaters, which can come in a wide variety of styles. These units, which typically take the form of a box or a tower, are portable, powerful, and capable of filling even sizable spaces. Ceramic heaters, especially forced-air (or “bladeless”) models, can assist distribute heat fast and evenly around a room.


Unlike convection heaters, which waste energy heating an empty room, infrared space heaters may quickly warm a room without wasting time. These heaters, which belong to the category of radiant heating, are most effective when there is nothing blocking the “line of sight” between the user and the heater.


Space heaters with a stone (mica) heating element that emits electromagnetic waves when heated are called micathermics and are available as panel heaters like oil-filled types. They generate heat in two ways: convection and radiation. High efficiency, but few design options at the moment. Similar to a massive metal panel is the appearance of many.

Heating Capacity in Relation to Room Size

There is a space heater for any need thanks to the wide range of sizes and outputs available. The standard recommendation for heat output, expressed in watts, is 10 watts per square foot. To heat a 100-square-foot room, you’d need a heater with a power output of 1,000 watts.

Desktop models typically range from 200 to 400 watts, making them ideal for spot cooling or warming up smaller rooms, such as a home office. A space heater with a 1,500-watt output will adequately warm a 10-by-15-foot room. Large electric heaters, maybe exceeding 2,000 watts, may require a dedicated circuit.

Efficient Use of Energy

While space heaters aren’t designed to take the place of a central heating system, they can provide sufficient warmth for one or two rooms at a significant cost reduction. As the seasons shift and certain rooms of the house become cooler than others, this is a common occurrence.

Features built into space heaters further reduce their energy use. More precise regulation of the heating system is made possible by thermostats and a variety of heat-setting options, which results in reduced energy consumption. Most heaters do not have an automatic “on” option, but sleep or auto-off timers can be programmed to turn the heater off after a certain amount of time.

Mobile apps on smartphones make it possible to connect from virtually any location. Wi-Fi connectivity allows for a growing number of control options, such as remotely activating the appliance so that rooms are warm when people return from work or school. Another option is voice control with smart speakers like Amazon’s Alexa or Google Home. Providing the user with more options means more efficient use of energy.

Safety Features

A word of caution: some space heaters get hot enough to touch, so keep kids and pets away from them if they’re in the room. It’s also important to leave some distance between the heater and any fabrics or soft furnishings. Finding housings that stay cool to the touch could be a good extra safety measure to take.

A space heater’s overheat protection will turn it off if its interior temperature rises above a certain threshold. In the event that a space heater is knocked over or falls, it will often shut off automatically.

Space heaters that burn propane or kerosene produce deadly carbon monoxide gas that can build up in enclosed spaces and pose a health risk if not properly vented. Depending on the type, some indoor heaters contain a sensor that turns off the appliance if the oxygen level drops to a dangerous level.

Volume of Noise

Noise levels vary, but even the most powerful and efficient electric space heaters are rarely rated as loud. The fan is typically to blame. However, oil-filled and micathermic types, as well as some infrared models, typically do not have a fan. Though they may generate some initial noise as they heat up, once running at full capacity, they are remarkably silent.

Forcible-air types of ceramic space heaters emphasize their use of a blower. That’s why they tend to get louder when turned up to eleven. Just a fraction of manufacturers list their products’ decibel levels. While most heaters are quiet enough to use in a bedroom, those with stronger fans may be too much.

Tips for Efficiently Heating Your Home

If you want to save the most money on your heating bills, it doesn’t matter what kind of space heater you buy—you just need to get one that’s the proper size for the room. When taking it from room to room, the maximum available space should be used, or the heater will have trouble keeping up with the demand.

  • However, there is no use in oversizing. Accuracy is key to maximizing heat output while minimizing operating expenses. In the event that the two rooms have vastly different sizes, it may be necessary to purchase two heaters.
  • Before using the space heater, make sure you have read the handbook and are familiar with all of its functions and settings.
  • Close doors as much as possible while using a space heater in a room to keep the warm air inside where it belongs.
  • Keep at least three feet of space between the space heater and any material, even if the exterior of the unit is quite cool. If you want to know if the manufacturer suggests a specific distance between the wheels, check the manual.
  • The heater’s ability to be left on overnight should be evaluated if it will be used in a bedroom.
  • Running cords under rugs or carpets is dangerous since any damage done there can go undiscovered.
  • If you want to use a space heater at night, look for one with an overheat safety feature.

Pros and Cons of Different Models

When it comes to choosing an electric heater, it’s important to consider both the benefits and drawbacks of different models. There are a variety of electric heaters on the market that vary in size, power output and usage efficiency. Some popular types include oil-filled radiators, convection heaters, wall-mounted fan heaters, quartz infrared heaters and ceramic space heaters.

Oil-filled radiators are great for large areas like garages or workshops. They have a low wattage output and require minimal maintenance. The downside is that they take time to warm up and can be bulky and difficult to move around.

Convection heaters are ideal for small spaces such as bedrooms or offices as they provide even heating throughout the room quickly. However, some models may be noisy during operation due to their fan systems.

Wall-mounted fan heaters are great for targeted heating needs in a particular area of a room. They’re also easy to install and don’t take up much space but may not be able to effectively warm larger areas due to their limited power output.

Quartz infrared heaters use radiation to transfer energy directly from one object (the heater) to another (the user). This makes them efficient at heating objects rather than air so they don’t dry out the air like other types of electric heater might do. However, they tend to be more expensive than other types of heater due to their complex design.

Ceramic space heaters are great for those who want fast heating without creating any noise or drafts – plus they don’t take up much space which makes them perfect for small rooms or apartments! But these kinds of electric heaters can become hot when in use so care should be taken with children or pets in the vicinity.

All these different models have their own pros and cons that should be carefully considered before making your purchase decision so you get the best results from your electric heater!


Energy-efficient space heaters were discussed in detail above, and the top models were selected after extensive field testing. The complexity of the topic, however, means that further problems frequently arise. We’ve included below the answers to some of the more frequent inquiries we’ve had.

How can I tell if a space heater is energy efficient?

Regrettably, no accepted norms exist. Oftentimes, people will say that a space heater is certified efficient because it has an Underwriters Laboratories or Electrical Testing Laboratories listing. Space heaters with a thermostat are recommended by the U.S. Department of Energy to prevent the room from becoming too hot.

What is the most efficient space heater?

This is a challenging issue to answer because of the wide range of possible influences. Although infrared is likely the most effective option, it is not always the best one. If you’re looking for the most energy-efficient space heater, make sure to take into account the aforementioned criteria.

How much would a day’s worth of electricity for a 1500-watt heater be?

The price to run a 1,500-watt energy-efficient space heater for a day can range from $7 to $9, depending on the utility rates in your area, the size of the room, and the quality of the insulation.

Space heaters or central heating—which uses less energy?

If you want to keep the entire house at the same temperature for weeks at a time, central heating is the way to go. There are three ways in which space heaters are more efficient:

  • To warm one’s own quarters.
  • The original central heating system was expanded with the addition of heating rooms.
  • Modifying the temperature in only one or more rooms when you don’t want to warm the entire house.

What type of space heater uses the least electricity?

Kilowatt-hours are the standard measure of electricity use. The kilowatt is the unit of measurement for electrical power. Since the amount of energy used is proportional to the wattage of the appliance, reducing the power consumption might result in significant cost savings. The most energy-efficient space heaters have lower heat settings (personal heaters with 200 to 400 watts), but they aren’t powerful enough to adequately heat living areas.


Ultimately, choosing an electric heater comes down to finding one that is efficient enough to meet your needs while providing you with comfort and convenience. Whether you are looking for something small like a space heater or something large like a whole house heating system – there are plenty of great options out there. We hope this article has provided you with enough information to make an informed decision about which electric heater is right for you.
