Best Space Heaters of 2021

Looking for a new space heater? We’ve selected the top 33 picks in 11 categories. Scroll down to check out all the best space heaters around.

All 33 Space Heaters We Recommend


Best Electric Space Heaters

Electric space heaters are the first thing people look for when searching for a new heater for their home. They come in a variety of sizes and designs and include both convection and radiant heat models. No matter what model you like, an electric space heater offers a quick and easy way to take the edge off a cold day. From floor to wall-mounted options, they suit most homeowners.

Best space heater for: small to mid-sized rooms, offices, workshops


Best Large Room Space Heaters

The electric space heater category above includes a wide range of models, some of which are perfect for large rooms. Alternatively, you could get a propane one. Regardless of the type of heater you want to buy, all space heaters for large rooms share a few features, such as high BTU and adjustable heat output. Before buying, check the noise level and fuel/energy consumptions, as some of them are quite loud while others could be expensive to run.

Best space heater for: large rooms and hallways, open-space offices, shops


Best Electric Fireplaces

Do you want more than just heat? An electric fireplace could easily suit your needs. These heaters add high aesthetic value to your living space. Energy-efficient and relatively cheap to run, but they usually have lower heat output.

Best space heater for: living rooms, family rooms, home offices


Best Infrared Heaters

If you’d rather pay a higher premium for lower running costs, the infrared heaters could be the best choice for small and big rooms alike. They’re quiet and energy-efficient, too, but perhaps not the best choice for buyers on a tight budget.

Best space heater for: nurseries, bedrooms


Best Oil Heaters

While the infrared heaters may be quiet yet expensive, the oil heaters come as an alternative for people on a budget. Their greatest highlight is the outstanding heat retention that makes them cheap to operate, too. We also like the fanless, radiant heat they provide. Since there is no fan to move the air around, the oil heaters are perfect for people with allergies.

Best space heater for: bedrooms, nurseries, people with allergies


Best Outdoor Heaters

Most of the electric heaters described until now are more suitable for indoor rather than outdoor use. But this doesn’t mean that you have to freeze in your yard or on a worksite. Manufactured specifically for outdoor use, the heaters in this category let you use your patio long after the leaves have started to fall. They usually use propane as fuel, and some can also be used in covered porches. Keep in mind, though, that some may need constant supervision and can pose a fire hazard.

Best space heater for: gardens, patios, worksites


Best Garage Heaters

Similar to the outdoor heaters in terms of power and size, they use either electricity or kerosene to ensure higher heat output and efficient heating of icy environments, but running such a heater is usually expensive. Models vary from freestanding to wall-mounted.

Best space heater for: home garage, industrial halls, large workshops


Best Portable Heaters

Small, lightweight heaters that can be easily moved from one place to another. A compact footprint makes them suitable for very small spaces.

Best space heater for: small rooms, log cabins, RVs


Best Propane Heaters

We mentioned propane as a fuel for the outdoor heaters, but the truth is that indoor heaters can use propane, too. Before getting such a model, remember that they could release carbon monoxide. For this reason, you should make sure the model you want features clean burning and that you’re using the heater in well ventilated spaces.

Best space heater for: garages, home, camping and tailgating


Best Ceramic Heaters

Ceramic heaters are a kind of electric heaters that provide instant heat and are perfect for small rooms. Heat retention is poor, but the surface of these heaters typically stays cool to touch. Not as effective as infrared heaters, but cheaper to buy.

Best space heater for: small bedrooms and bathrooms, nurseries, households with small children


Best Baseboard Heaters

Minimalist and discreet, these heaters maintain a low profile that doesn’t interfere with the room’s aesthetics, but they need a dedicated circuit to supply power for proper functionality.

Best space heater for: using instead of a central heating system

Best Electric Space Heater

key considerations
Electric Space Heaters Reviews

With electricity and wall outlets available in most homes, these heaters can suit most purposes. They come in all sizes, delivering either convection or radiant heat. They are also easy to use and pose little to no hazards. With this in mind, here’s what you should check before buying.

  • Energy efficiency: To prevent your energy bills from skyrocketing, get an energy-effective model. Compare the models and get the one with the lowest watts that can still output the heat level you need.
  • Noise level: Fanless heaters, such as those using radiant technology, are a more appropriate choice if you want to keep noise levels low.
  • Cool to touch: Whether you have kids, pets, or live alone, this feature will prevent accidents and unwanted injuries.
  • Auto-off function: Turns off the unit automatically if the internal temperature rises above a threshold or in case of blackouts.

2 Lasko FH500 Review

If Dyson’s price tag is out of your reach, but you’d still like a fan and heater combo to use all year round, then you might like the Lasko FH500. Design-wise, it might not be the most attractive; nevertheless, it impresses with a compact footprint and high heat capacity, two features that makes it perfect for smaller as well as bigger spaces.

Powered by a 1,500-watt ceramic core, this oscillating heater can keep you toasty throughout the winter thanks to three heat modes. Furthermore, we like the combination fan and heater mode that heats the room faster.

While some people might find it a bit noisy, others might like the sound of the fan that produces a relaxing white noise – just perfect for a bedroom. Furthermore, the unit is simple to operate from an intuitive control panel.

Safety features include a cool-touch housing, overheat protection, and auto shut-off if the unit is tipped over. Affordable for what it is, this is the best electric heater your money can buy.

TRUSTECH PTC903 1500W Portable Space Heater

Best electric heater for low budgets

Very compact dimensions make it perfect to use at home or in an RV, but it’s not your best bet for bigger rooms.

Check price on Amazon

3 TRUSTECH PTC903 Review

If you’re looking for a small electric heater to warm up a small room or an office cubicle, the TRUSTECH PTC903 might be it. In a world where almost everything is digital and technologic, this heater strikes with its simplicity.

Traditional dials rather than a digital control panel make it equally easy to use by Baby Boomers, Millennials, and GenZers alike.

Three heat settings and an adjustable thermostat allow you to reach the desired temperature fast and maintain it without hassle, while tip over and overheat protection add a layer of safety.

Small, compact, and portable, the TRUSTECH PTC903 is not a good choice for ample spaces, but it’s ideal for small rooms, RVs, and even for keeping warm a small greenhouse or shed.


Best Space Heater for Large Rooms

key considerations
Large Room Space Heaters Reviews

Whether electric or gas-fueled, these heaters impress with high heat output. Measure the size of your room and match it with the unit’s BTU output to make sure the unit you want can truly heat up the entire space.

  • Fuel options: Electric heaters are undoubtedly the most popular; they are safe to use indoors and intuitive to turn on and operate. Alternatively, you could opt for propane heaters, which could be cheaper to run but come with more hazards.
  • Calculate wattage: When you have to heat a large space, the watt output can tell you whether the heater can serve its purpose. As a rule of thumb, you need 10 watts of power per square feet.
  • Technology: If you decide to go for an electric heater, decide between convection and radiant heat. Convection heaters heat the air rather than the objects and are great for larger rooms. On the contrary, radiant heaters – such as infrared ones – are more suitable for smaller spaces.
  • Thermostat: Big heaters consume more energy than smaller ones, regardless of their energy-saving rating. A thermostat can help you save on your bills by simply turning off the unit when the temperature in the room has reached the desired level.

2 Cadet 67527 Review

The Cadet 67527 might not be the right heater for large bedrooms due to its louder operation, but it’s definitely perfect for your larger living spaces. We particularly like its wall-mounted design that can save you loads of floor space.

Its dual coil elements and upflow design for increased air circulation deliver fast heating of the air. Furthermore, you can choose from models with or without thermostat.

This space heater isn’t the most appealing in terms of style, but it’s efficient, durable, and affordable. Warming up areas up to 600 square feet, it surely brings true bang for the buck.

3 Dr. Infrared Heater DR968 Review

Heating a large room without spending too much is possible, thanks to Dr. Infrared Heater DR968. As its name suggests, it uses infrared technology to transfer heat to objects rather than the air.

Allegedly, it can deliver 60% more heat than a convection heater. That’s debatable, but we can’t argue that it’s more effective than your average electric heater.

We also like its cabinet style with caster wheels that allow you to easily move it from one room to another. A programmable timer and intuitive control panel are other highlights—all in all, an excellent choice for people on a budget.


Best Electric Fireplace

key considerations
Electric Fireplaces Reviews

Aesthetically appealing, electric fireplaces can bring coziness into your home. They are a great choice for a living room or bedroom, as well as commercial premises. Check out the following factor before buying.

  • BTU: The thermal units are important on all heaters, but a crucial factor when choosing an electric fireplace. Most brands focus on aesthetics rather than functionality, so if you want a fireplace that can truly keep you warm on a cold day, make sure its heat output matches the size of your room.
  • Style: Consider the overall style of your room to decide what type of electric fireplace works best in your space. Options include fireplace inserts, freestanding and wall-mounted units, as well as fireplace stoves.
  • Operating costs: Unlike standard space heaters, electric fireplaces also feature lights and sometimes moving elements that add up to the aesthetic factor. All these extras consume energy, so if you want to keep operating costs low, pick a model with LED technology.
  • Fire without heat: If you live in a warmer climate area and don’t want to give up the idea of a fireplace, consider a model that allows you to turn on the flame effect without turning on the heat.

2 Duraflame DFI-5010 Review

If you’re looking for the coziness and warmth of a real fireplace, check out the Duraflame DFI-5010. More than a fireplace, this electric stove fits perfectly in all environments, despite its rustic look.

Its greatest feature is the standalone design that allows you to simply move it from one room to another.

We also like the patented 3D flame effect, as well as the infrared quartz element. The heat output is not outstanding, but it’s still perfect for rooms up to 1,000 square feet. In other words, a great choice for most people.

Best budget

R.W.FLAME 30 Inch Recessed and Wall Mounted Electric Fireplace

Best for small rooms

Wall-mounted or recessed installation options make it perfect for all homes.

Check price on Amazon

3 R.W.FLAME 30 Review

Similar to our best-in-class, the R.W.FLAME 30 is a modern, wall-mounted electric fireplace, but it’s designed for smaller spaces. It provides both aesthetic value and heat in rooms up to 400 square feet.

What makes it stand out is the multi-operating mode that allows you to pick from 12 flame styles, various bed colors, as well as five flame speeds and brightness modes. The effect is not as realistic as PuraFlame’s, but you’ll still get a cozy fireplace feel.

We also like the slim profile that looks better when mounted directly on a wall and not in recessed style. The control panel is simple and intuitive, while two heat options let you choose between no-frills warmth or energy efficiency. No doubt, a great pick for a smaller budget.


Best Infrared Heater

key considerations
Infrared Heaters Reviews

Perhaps the best type of electric heater for those who want to save a buck in the long run, infrared heaters impress with low operating costs. Unlike convection heaters, they don’t heat the air but the objects in the room – more or less like the sun heats the ground. For this reason, you’ll feel the heat almost instantly as long as you’re facing the appliance.

  • Purpose: To make sure the heat output matches the size of the room, measure your space before buying. If you plan to move the appliance from one room to another as needed, make sure the heater you want matches the size of the biggest room you plan to use it in.
  • Timer function: Infrared heaters are designed to save you money, but you can save even more with a timer that can turn the unit off after a set period of time.
  • Warranty: Using advanced technologies, infrared heaters are often more sensitive than the convection kind. Thus, a longer warranty can save you loads in case of malfunctions.
  • Oscillation: This function directs the infrared radiation at different angles, for more efficient heating of your room.

3 Air Choice 80B Review

The Air Choice 80B comes as an alternative to the other infrared heaters on this list, suiting both small spaces and people on a budget. It’s small enough to fit in an RV – or even to use in a tent, should you pair it with a power generator.

Despite its size, it impresses with high heat output. Two heat settings and plenty of safety features are other highlights. You can expect automatic shutoff in case of overheating or tip over. The unit also stays cool to touch, so it’s safe to use around children.

Capable of heating you in a matter of seconds, portable, and affordable, this is one of the best infrared heaters if you don’t want to break the bank.


Best Oil Heater

key considerations
Oil Heaters Reviews

Oil heaters are the most cumbersome space heaters for home use. They are relatively big and have little aesthetic value. However, they are effective, cheap to run, and even cheaper to buy. As their name suggests, they are filled with oil – a liquid that preserves heat and slowly transfers it to the environment after you’ve turned off the appliance. The oil doesn’t have to be changed, so they require little to no maintenance.

  • Heat retention: The main advantage of oil heaters is that they can retain heat for a long time after you’ve turned them off. If this is your main purpose, steel units will retain heat for longer and are more durable than aluminum ones.
  • Type: Depending on your needs, you can pick from wall-mounted units, freestanding models with legs, or wheeled models you can move from one room to another.
  • Heat controls: Most oil heaters have a traditional design with on/off knob. However, some units also feature adjustable heat levels – a function that helps you save even more.
  • Heating time: Oil-filled heaters may take some time to heat up, which could be a drawback. If you don’t want to spend too much time in a cold room after getting back home, check the various models, and pick one that can heat up relatively fast.

Like the Aikoper, the PELONIS 2019 is a great choice for noiseless heating or people with allergies. In terms of features and performance, the two heaters are very much alike. However, the finishing details and aesthetics look better on our best-in-class.

That said, you can still expect three heat settings, a thermostat with eco mode, as well as a 10-hour timer. Power indicator lights will let you know when the unit is on, while a tip-over switch will turn it off if inclined at angles higher than 30 degrees.

Easy to operate from a distance thanks to the remote control and easy to move around your home, this is the best oil heater for the money.

With analog rather than digital controls, it’s easy to operate by most people. There is no remote control, either, but it does come with a thermostat that allows you to maintain the desired temperature level without hassle.

Simplistic in function and design but cheap, this oil filled radiator is perfect for smaller rooms.


Best Outdoor Heater

key considerations
Outdoor Heaters Reviews

Throwing a garden party, enjoying a camping trip, or working outdoors in winter doesn’t have to mean freezing to death. An outdoor heater can save you from frostbites, but there are a few things to consider before getting one.

  • Fuel type: Like garage heaters, outdoor heaters can be fueled by electricity, propane, or natural gas. Propane is your best bet if you need an ultra-portable unit; electric outdoor heaters are great for semi-enclosed spaces or tents, while natural gas ones can save you money in the long run if you have a natural gas outlet in your yard or worksite.
  • Safety tilt switch: Turns off the heater or prevents ignition if the unit is tilted or placed on an uneven surface.
  • Dome design: You can choose from single-dome and 3-dome outdoor heaters. The former radiate heat in only one direction, while the latter in three different directions rather than just one.
  • Portability: Not all outdoor heaters are portable, and sometimes you might not need portability features either. Choices include wall-mounted, freestanding, tabletop, and portable units that come either with wheels or carrying handles.

In other words, you can use it outdoors as long as you keep it out of the rain. That said, the unit is easy to operate and performing. An excellent choice if you want a safer option for a semi-enclosed space.


Best Garage Heater

key considerations
Garage Heaters Reviews

Whether you want to use your garage as a workshop or just love spending time with your car, a garage heater can help you enjoy this space even when the temperatures drop. You can pick from a wide range of electric or gas-powered heaters, but make sure the model you want comes with the following features.

  • Adjustable louvers: Allow you to direct the heat where you want it without moving the entire unit.
  • Wall mounting: It doesn’t matter how big your garage is; a wall-mounted heater will never get in your way.
  • Power rating: Garages usually have poor insulation, that’s why a garage heater should have higher power than a regular space heater. As a rule of thumb, go for a unit with at least 4,000-5,000 watts.
  • Clean fuel burning: If you decide to get a gas-powered heater, make sure it is designed for indoor use.

Cheaper than most garage heaters and truly capable, it’s a great choice for individuals and businesses on a budget.


Best Portable Heater

key considerations
Portable Heaters Reviews

Either you need a heater to move from one room to another or one to heat your tent during your winter outdoor adventures, a portable heater is all you need.

  • Dimensions: There is a huge difference between full-size heaters with wheels meant for home use and compact units you can take anywhere. The latter usually have carrying handles, are lightweight, and easy to transport.
  • Purpose: Do you want to heat a confined space, or do you need a portable outdoor heater? Outdoor heaters may release more toxic fumes and are not suitable to use indoors or in a tent.
  • Maintenance costs: Electric heaters are cheaper to maintain, but not your best bet for camping. Gas-fueled heaters, on the other hand, need regular maintenance.
  • Ventilation requirements: You should check this feature if you plan to buy a portable propane heater. Even if the model is designed for indoor use, gas heaters may still require proper ventilation.

Best Propane Heater

key considerations
Propane Heaters Reviews

Propane heaters come as an alternative for those who can’t operate an electric heater or electric stove. They are a perfect choice for the outdoors or well ventilated spaces, such as log cabin, garages, or even in a tent. They could be used indoors too, as long as your room is properly ventilated, and only if the manufacturer deems the heater as safe to use indoors to prevent carbon monoxide intoxication.

  • Clean burning: Like all gas heaters, propane heaters may release carbon monoxide and could be unsafe for indoor use. To prevent accidents, make sure the model you want features clean burning and has a low level of emissions.
  • Ignition: The vast majority of propane heaters feature automatic ignition, but some of the smaller models may require you to ignite the fuel with a match.
  • Blower fan: Propane heaters may or may not have a blower fan; a fan speeds up the heating, but if it is too loud, it can easily become annoying.
  • Safety shutoff: Turns off the heater if it detects low oxygen levels or if the unit is tripped over.

1 Mr. Heater F271390 Review

The Mr. Heater F271390 is similar to the Dyna-Glo RMC-FA60DGD portable heater we already talked of, but it’s more powerful and ideal for larger outdoor spaces.

In terms of performance, expect up to 125,000 BTU, or more than enough to heat up to 4,250 square feet. Low fuel consumption also allows it to run for up to 17 hours on a single 100-lb tank.

The unit is not the most portable out there, but you can move it from worksite to worksite without too much hassle. We also like that it’s quieter than most similar heaters, albeit still too loud to use for leisure purposes.

Mr. Heater forced air propane heater also comes in a smaller as well as a bigger variant, so you can choose the most appropriate one.

2 Mr. Heater F299730 Review

Propane heaters are often seen as heaters for the outdoors, but some models are perfectly suitable to use indoors, too. A fine example of an indoor propane heater is the Mr. Heater F299730, a unit perfect for larger rooms.

Aesthetically speaking, it can easily compete with an electric fireplace while providing the warmth of a real flame.

Installation options include wall-mounted or freestanding, while a built-in thermostat boosts fuel efficiency while maintaining the temperature at set levels. It won’t work at high altitudes, and you should only use it in well ventilated rooms due to potential carbon monoxide release. With this in mind, it’s a great pick if you’re looking for a more cost-effective alternative to an electric heater.

3 Mr. Heater MH18B Review

The Mr. Heater Big Buddy is Buddy’s bigger brother, but the two propane heaters share a wealth of common features. From a similar design to suitability to use both indoors and outdoors, the two models are very much alike.

What makes the Big Buddy different is the higher heat output that makes it perfect for spaces up to 450 square feet.

Three heat settings make it perfect to use in smaller and larger rooms alike, while a sturdy handle ensures seamless portability. Like most Mr. Heater propane heaters, the Big Buddy features automatic low oxygen detection shutoff system as well as accidental tip-over shutoff – a great choice if you want a quality heater at a price that won’t break the bank.


Best Ceramic Heater

key considerations
Ceramic Heaters Reviews

Ceramic heaters come as an alternative to infrared ones. They are perfect for smaller rooms and are cost-effective. The main difference between infrared and ceramic is that the latter heats the air rather than the objects – a much better choice if you want to maintain the temperature in your room using a thermostat.

  • Type: You can choose from tower heaters, wall-mounted or compact, portable models, based on the size of the room you want to heat.
  • Noise level: Most ceramic heaters feature blower fans that disperse the heat into the environment. If you want to use a ceramic heater into your bedroom, make sure it comes with a quiet fan.
  • Coverage: Since ceramic heaters heat the air rather than the objects, check the wattage or BTU output and see if the one you want can heat your room effortlessly.
  • Temperature settings: Go for a heater that comes with various temperature settings as well as a thermostat.

The Lasko 751320 is proof that ceramic heaters are not out of fashion. Boasting a stylish design and incorporating new technologies, it is a great choice for rooms up to 300 square feet.

Its greatest feature is the widespread oscillation that helps heat the room faster. Two heat settings and an internal thermostat keep the temperature at comfortable levels, while the 4-hour timer allows you to turn it on and forget it.

Best Baseboard Heater

key considerations
Baseboard Heaters Reviews

Discreet and effective, these are some of the best all-space heaters. Coming in various sizes, they are ideal for homes, hotels, and commercial premises where the installation of a permanent heater is desired. Here are a few things to check before buying.

  • Electric or hydronic: You can choose from electric and hydronic baseboard heaters. Electric ones are the most popular due to their simple installation, but hydronic is desired if you want to hook them to a central heating system.
  • Expert installation: The initial and running costs are only part of the picture. Baseboard heaters need expert installation and periodical maintenance – two things to weigh in before buying.
  • Type: Do you want a standalone baseboard heater to use in a room or a model you can integrate into your central heating system?
  • Front louvers: Allow you to change the direction of the airflow, enhancing heating efficiency.

Space Heater Buying Guide

all your space heater questions answered

What is a space heater?

A space heater is a self-contained appliance designed to heat a single space at a time, as opposed to the central heating systems that can heat various rooms simultaneously. A space heater is, after all, an umbrella term that refers to a variety of electric or gas-powered units.

While most people think of indoor use when talking about space heaters, the truth is that you can pick from a range of indoor and outdoor space heaters, based on your needs.

Various types of space heaters

Whether you need an indoor or outdoor heater, you can pick from the following types:

  • Electric space heaters
  • Electric fireplaces
  • Oil-filled radiators
  • Infrared heaters
  • Outdoor heaters
  • Garage heaters
  • Portable heaters
  • Propane heaters
  • Kerosene heaters
  • Natural gas heaters
  • Ceramic heaters
  • Baseboard heaters

Best space heater brands

Before talking about features and ways to select the best space heater for you, it is essential to know which heater brands deserve your attention. Oftentimes, it’s easy to find cheap yet powerful units, but if the brand isn’t trustworthy, you might spend more on repairing or replacing the space heater. With this in mind, here are some of the best space heater brands that deserve your attention:

  • Dyson heaters: A true innovator, Dyson is known for its unrivaled home appliances. Their space heaters are some of the safest for the whole family, and most models combine heat and cooling function, for year-round use. You’ll have to pay for these technologies, though.
  • Mr. Heater: Mostly known for its propane heaters, Mr. Heater appeals to those who need to heat larger, ventilated areas or outdoor spaces. The heaters boast clean combustion and are safe to use indoors.
  • Lasko heaters: Proposing a range of electric heaters, Lasko appeals to homeowners as well as commercial users looking for affordable, mid-range space heaters.
  • Duraflame heaters: Specialized in infrared heaters, Duraflame proposes a range of standard space heaters as well as a selection of electric fireplaces at affordable prices.
  • Opolar heaters: Another brand addressing those who look for affordable solutions, Opolar impresses with a range of small ceramic heaters for smaller rooms. Resistant to moisture, their units are also ideal for bathrooms.

Besides the heater brands above, other companies that deserve your attention include Dr. Infrared, Heat Storm, DeLonghi, and AmazonBasics.

What is the best space heater for me?

There are so many types of heaters on the market, and so many models in each category, that finding the best space heater for you can be troublesome. That’s why your research should start with a few questions:

  • Where do you want to use the heater? Indoors, outdoors, or both inside and outside of your home?
  • What room do you want to heat? A ceramic heater, for instance, could be an excellent choice for a living room, but it could be too loud for your bedroom due to the fan. Electric heaters could be unsafe to use in a bathroom, while propane models could be unsafe to use indoors.
  • What size is your room? Is the heater you want to buy powerful enough to warm up the entire space?
  • Is the heater cool to touch when on? If you have kids or pets – or if you want a freestanding model to place directly on the floor – make sure its surface will not overheat.
  • Do you suffer from allergies? Ceramic heaters – or any other heater that uses a fan – can easily spread out allergens. If you suffer from allergies or respiratory problems, an oil heater or an infrared one with no fan are your best bets.

Once you’ve answered these questions, decide whether you want an electric or propane unit and whether you need a portable or permanent heater.

Electric vs. propane heaters

Nowadays, you can choose from both electric and propane space heaters for both indoor and outdoor use.

  • Electric heaters: Are often cheaper to run and more environmentally friendly than propane ones, but they are not always suitable to use outdoors in adverse weather. To operate them, you also need access to a wall outlet or power generator, should you plan to use an electric heater in remote locations.
  • Propane heaters: Are more efficient than electric models, heating your space faster. Most models are portable, with the smaller ones using camping-sized propane cylinders. They can be used in all conditions, even in the case of electricity blackouts. However, they pose more hazards than electric heaters and are often more expensive to run.

Permanent vs. portable heaters

Based on the size of your room and purpose, you can choose from permanent or portable space heaters.

  • Permanent space heaters: Are designed for larger spaces and come as an alternative to the central heating systems. Besides heat, some models also bring aesthetic value – for instance, you can create a focal point in your living room with an electric fireplace, or mount a baseboard heater to replace a freestanding unit.
  • Portable space heaters: Are more appropriate for smaller rooms and come as an alternative to the permanent heaters and central heating systems. Their most significant benefit is the lower running cost compared to both permanent and central heating solutions. Besides home use, portable heaters are also suitable to use outdoors for leisure or work purposes.

What space heater to buy?

In a nutshell, you should get a:

Space heater type


Portable electric heater

Single-room heating, indoor use, ideal for smaller rooms

Portable propane heater

Single-room heating, indoor and outdoor use

Permanent heater

Effective heating of larger rooms, offices, garages, and warehouses

How many watts or BTU do I need?

The most disappointing thing in a space heater is its inability to warm up your room effectively. More often than not, though, it is our fault. Failing to size the heater correctly can easily turn into frustration, so make sure you know how to calculate how many watts or British Thermal Units (BTU) you need before buying.

While it sounds complex, it all comes down to a simple formula.

To heat up a room effectively, you need 10 watts or 34 BTU of heat output per square foot (1 watt = 3.4 BTU). In other words, a 1,500-watt heater outputs 5,100 BTU and is suitable for spaces up to 150 square feet.

Likewise, a propane heater outputting 10,000 BTU is suitable for rooms up to 300 square feet.

With this in mind, regardless of what the manufacturer claims, calculate the square footage of your space and match it with an appropriate heater to prevent disappointment.

What is the best space heater for the bathroom?

Water and electricity don’t work together very well, that’s why it is recommended to avoid using an electric space heater in the bathroom. Showering in a frigid environment isn’t pleasant, though. If you don’t want to use central heating, you could either get a water-resistant portable electric heater or opt for a hardwired, wall-mounted unit. The latter is undeniably the safest option – just make sure the heater is mounted at a distance from your shower or bathtub to prevent steam from damaging the appliance.

How much energy does a space heater use?

Running costs are often a decisive factor when choosing a space heater. Knowing how much energy your model uses can help you estimate your monthly bills.

Most electric heaters use 1,500 watts per hour. To figure out how much it will cost you per day, multiply this figure by the number of hours you want to keep it on and divide by 1,000 (1 kilowatt) to figure out how many kilowatts your appliance uses per day.

Taking a practical example, let’s assume that you run the heater for 10 hours per day. So:

  • Multiply the number of watts by the number of hours: 1,500 x 10 = 15,000 watts/day
  • Divide the result by 1,000: 15,000 ÷ 1,000 = 15 kilowatts
  • Multiply the number of kilowatts by the electricity rate in your area. Assuming your company charges 0.38 cents per kilowatt, you’ll get: 15 x 0.38 = 5.7

In other words, you’ll spend $5.7/day to use your electric heater for 10 hours a day.

Obviously, most space heaters have multiple heat settings and eco modes that allow you to reduce these costs.

Features to look for in space heaters

With the above in mind, here are a few important features to look for, regardless of the type of space heater you want to buy.

  • Variable heat settings: Allow you to choose between energy efficiency or higher heat output, based on the room size and your budget.
  • Thermostat: A thermostat can help you keep costs even lower by turning off the appliance when the temperature in your room has reached the desired level.
  • Auto-shutoff: For safer operation, get a heater with overheat and tip-over auto-shutoff functions.
  • Mobility: Unless you want to replace the central heating system with permanently mounted units, get a heater with carrying handle or wheels, so you can move it from one room to another easily.
  • Efficiency: If you live in cold climate areas, go for a propane heater or an infrared one.
  • Aesthetic value: Last but not least, pick a space heater that looks good. There are many stylish models regardless of the heater size or type, and some can even double as room décor if you decide to get an electric fireplace or electric stove.
