9 Most Energy Efficient Space Heaters - Reviews

1. Delonghi HMP1500 Mica: Best Overall

Key Features:

  • Thermal cut-off that prevents overheating
  • Fanless radiant heat
  • Auto tip-over switch 
  • Ultra-thin panel, compact wheelbase
  • Uses micathermic technology 

The Delonghi is a highly efficient space heater that can reach its full heat capacity in just 60 seconds. It uses micathermic technology, producing both convection and radiant heat, allowing the build to be super thin. 

This model has 2 heat settings, high (1500W), low (750W), and a thermostat that monitors the room temperature and maintains it. The option for low heat at 750W means you can leave this unit running longer for less money. Micathermic technology doesn’t waste energy during the heating process, making it close to 100% efficient as the heater warms up. 

The more heat settings an electric space heater offers, the more energy efficient it will be. If you’re working from home all day and just need a little extra warmth in your office space, having the option to run the heater on the low setting will reduce energy waste AND your electrical costs. 

The Delonghi is attractive and subtle in a neutral black color with a narrow build that will fit into most spaces. If you’re trying to keep your floor space clear for kids to play or you need to move it out of the way to clean, the built-in multi-directional casters make it so portable. 

Pros

  • Whisper-quiet operation 
  • Highly energy efficient
  • Takes up minimal space 
  • High and low heat settings
  • Can mount to the wall

Cons

  • Heats well close up, but not the entire room

Who Should Get This? 

Ideal for homes with limited space thanks to the slim design and ability to mount to the wall to save space. People looking for minimal noise will love this product.

2. Honeywell HCE200B UberHeat: Best for the Money

Key Features:

  • Built-in thermostat
  • Compact size
  • 3-year warranty
  • Two different colors available 
  • Overheat protection
  • Automatic tip-over shut off
  • Energy efficient, low heat setting available

This is a small and cost-effective space heater option that is also great for saving energy, and it’s my pick for a budget option. Despite being an affordable choice, it has higher-end models’ safety features, including a tip-over switch, overheat protection, and cool touch housing

Portable and easy to use, you can choose to place it on a tabletop or the floor thanks to its compact size. The 1500W ceramic heating element functions with 2 heat settings. Using the low heat setting, you can stay cozy and avoid an outrageous electric bill. 

For those who live alone, this unit features a programmable thermostat and is a fantastic choice to keep whichever room you’re in warm. This allows you to turn down the heating for the house, keeping your costs down and reducing energy waste in the rooms that remain empty. 

There’s no better way to save money AND reduce your environmental impact at the same time. The Honeywell HCE200B UberHeat also comes in black or white, so you can match it to the style of the room you intend to use it in.

Key Features:

  • Sleep timer which cuts out if tipped over
  • Pivots on its center of gravity for oscillating motion 
  • Jet Focus forced air for even heating 
  • Focused or wide airflow 
  • No visible heating elements

A trusted brand with high-quality products. This electric space heater uses forced air for heating and doubles as a cooling fan in the summertime, so you get double the value for your money. 

It oscillates silently and doesn’t have any spinning blades, making it safe to use around children so your whole family can be comfortable. This is an excellent product for use in a busy household where you can’t keep an eye on the kids and pets around the heater 24/7. It’s advanced safety measures, like a tip-over automatic shut off, can give you peace of mind so you can stay warm and worry-free. 

This unit is ideal for nighttime heating as it features a sleep timer that can be set at intervals of 15 minutes to 9 hours. It also has whisper-quiet operation and intelligent heat control to create the ideal sleep environment. 

The Dyson is also the only space heater to feature a Jet Focus control. This provides far-reaching targeted heating, making it suitable for use in large open spaces, such as an open-plan lounge and dining area.

4. LifeSmart 3 Element Infrared Electric Heater: Most for Warming The Body 

Key Features:

  • 3 heat settings
  • Remote controlled 
  • LED 
  • 3 wrapped quartz infrared heating elements 
  • Overheat safety switch 
  • Cool-touch exterior 
  • Child safety lock 

The LifeSmart 3 Element Infrared Electric Heater is a classy product for an upscale home. Disguised as an oak cabinet, you can trick your guests into thinking this efficient source of heat came from somewhere fancier than your local Walmart. 

It’s available for an affordable price and does wonders for quickly heating your body. Because it uses infrared technology, it doesn’t heat the air in the room, but the people and objects in the vicinity so it’s not ideal for someone looking to heat the temperature of a room evenly. This heater is best for individuals who will sit close to the heater and warm their body temperature. 

However, the 3 quartz-wrapped heating elements emit a substantial 5,118 BTUs making it suitable for heating rooms up to 150 sq. ft. So, if you have a compact studio apartment, or cozy office space, this is the perfect unit.

The enhanced safety features, including a Cool Touch exterior and child safety lock, also make it a great addition to a family home. The unit offers 3 heat settings, 1000W, 1500W, and eco for managing your energy consumption, and an extra-large LED display panel, so you have complete control over the heat level in your home.

Pros

  • Lifetime warranty washable filter 
  • Safe for use around children 
  • Excellent for zone heating of one room or area
  • No assembly required 
  • 12-hour programmable timer 

Cons

  • Occasional hypersensitivity of the emergency shut off

Key Features:

  • Downdraft heating design to warm your floors 
  • Frost protection
  • Outputs 49dB at the maximum setting 

This is a well built and aesthetically-pleasing heater that can be mounted to the wall effectively, so it takes up minimal space. Manufactured by a reputable German company, it boasts many advanced features. 

Since it can be mounted high up on the wall and air flows down to the floor, this model heats the room evenly and efficiently. Downdraft heating means you can ditch the wooly socks and slippers because your floors will be toasty warm as well. 

It’s great for heating a basement where the floor can become cold VERY quickly. It also functions well in mudrooms in the house that don’t benefit from the central heating circulating through the rest of the home. It’s sleek and subtle, so even in a small room, you’ll be able to find space for this heater.

One of the features I LOVED on this unit was the booster timer. This feature allows the unit to operate at maximum heat for up to 60 minutes before it reverts to its preset thermostat setting, making it an excellent choice for warming your room quickly on chilly mornings.

Pros

  • Uses forced air to heat rooms evenly 
  • Reliable heat performance output 
  • Takes up minimal space thanks to the wall-mount capability

Gain the sophistication and coziness of a fireplace without the fumes and hassle of burning wood. This electric space heater has a reasonably average heat output of 1500W, more than sufficient to heat an area of 300 sq. ft. 

Great for offices, dorm rooms, dens, and other small spaces that just need a little bit of heat while remaining quiet so you can focus on working. It has advanced safety features, including overheat protection, that provide peace of mind to the user. It’s easy to use with minimal risk thanks to a one year warranty.

How to Choose the Most Energy Efficient Space Heater?

Choosing the most energy efficient space heater is a daunting task, but it’s worth investing the research time now to make the best choice for your specific heating needs. 

Let’s break it down to make it easier to know what you should look for in the best, most energy efficient space heater. By the end of this article, you’ll be an expert, never to be duped by a clearance sale price again. 

Heat Settings and Thermostat

Choosing an electric space heater that is energy efficient means paying close attention to what heat settings are at your disposal. Having a high and a low heat setting is useful because you can conserve energy and still stay warm by running the product on low heat most of the time. 

Between 750W to 900W is standard for a low heat setting, while an average setting for high heat is 1500W. Anything higher than that and you’re spending money on electrical costs unnecessarily. 

Also, keep an eye out for heaters that advertise adjustable thermostats or timers. These features are incredibly useful when you’re trying to conserve energy because they allow you to be specific in your home’s heating and not put out more power than you need. Reducing energy waste also reduces your costs

Type of Heat

The type of heating your electrical space heater will impact how efficient it is in heating your home. Infrared space heaters are becoming very popular in today’s market, but they do very little to heat a room. Instead, they’re useful for keeping people warm within the room, as long as they are in close proximity to the heater. 

Forced air is more effective at heating an entire room evenly, and downdraft heating is useful if you’re trying to prevent a cold floor. Understanding how you want your space to be heated will have a significant impact on the type of heat you choose to go with. 

Portability of the Heater 

If you want to maximize your energy efficiency, it’s best to keep the overall heat on your house low and use the space heater to warm whichever room you are spending time in. 

To do this easily, you must select a space heater that is easily portable and transferred between rooms with minimal effort. If your selection is wall-mounted, investing in multiple heaters for the rooms you frequent the most allows you to turn them on in whatever space you are using at the time. 

Safety Features 

Choosing the best, most energy efficient space heater also requires considering what safety features that model features. If there’s no tip-over switch for automatic shut off, this is not only a safety concern but can result in wasted energy, and by default, wasted money. 

Overheat safety functions are also essential for conserving energy and keeping your family safe while using the space heater in your home. 

Final Verdict: Our Top Choice

The Delonghi HMP 1500 Mica is our top pick for the most energy efficient electric space heater thanks to its versatility. There is something for everyone to love about this model because it is narrow and portable on caster wheels for those who want something they can move between rooms, but it is also wall-mountable if you’re looking for a semi-permanent unit to heat one specific space. 

The 2 heat settings increase its ability to save energy, and you can use the low setting at 750W along with the adjustable thermostat to keep a space warm longer for less money

Overall this model offers the most benefits that result in energy efficiency and essential safety features, all for a reasonable price.
