When it’s uncomfortably cold, nothing heats your space quicker than small room heaters. They are excellent standalone heating appliances, which can also be used instead of your home’s HVAC system.

Since there are so many options on the market, narrowing down to a good fit can be overwhelming. This is where we come in. We created a list of the nine best heaters for small rooms. While researching and reviewing, we made some keen observations that are also included in the guide below.

How to Size a Small Room Heater

Before you purchase a new heater, make sure to size it up. You would not want to buy one that does not have enough heating power (BTUs) to warm-up your room:

Here’s what you need to do:

  • Measure your room’s width and length and multiply it to know the room’s size in sq. ft.
  • Calculate how many watts your small room requires. Generally, each sq. ft. requires 10 watts, so multiply it with the total square footage of your room, and you’ll have the number of needed watts.
  • For converting watts into BTUs, you should do the following: One watt is equal to 3.4 BTUs. Therefore, multiply the total watts by 3.4 BTUs.

Besides these, many other variables influence your room’s heating capacity, including window placements, high ceilings, staircases, cement floors, and inadequate insulation jobs.

Optimizing Small Room Heating

Installing a small heater is a convenient and effective way to save money and get adequate heat.

These inexpensive units require little to no installation and are known to conserve energy. Even though they have a small form factor, the derived heat is more than enough for small rooms. Large rooms are a different story. visit our guide on heating bigger spaces here.

Its efficiency depends on the size of the room and furniture density. If you’re looking for an appliance to warm just one room or work as a backup, look no further than a small room heater.

Choosing a Quality Heater for Small Spaces

Room Size vs. Heat Output

When searching for a small room electric, wall, or space heater,  you should know the exact area it will cover. You can determine this through the heater’s wattage.

Typically, a small room heater requires only 10 watts of heating power per sq. ft. to provide adequate heat. Therefore, a standard 1500-watt unit can cover 150 sq. ft. of space with ease.

Remember, a heaters’ coverage depends on how your house is set up and the heating method you use.

Heating Method and Heater Style

Another important thing you should consider when buying a small room heater is the heater type. Though there’re various styles to choose from, there are three conventional heating methods: radiant, fan forced, and convection.

While convection heaters normally offer even heat, radiant heaters provide fast, efficient, localized heating. Additionally, fan-forced heaters circulate air over the heating element and then push the heated air into the room. These are commonly found in garages and basements.

Besides the different heating methods, heaters come in various styles. These include tabletop heaters, wall-mount heaters, standalone or floor heaters, tower heaters, fan heaters, fan-less heaters, panel heaters, baseboard heaters, and many others.

Safety Features

If portable heaters aren’t monitored properly, they can become common fire hazards, which is why it’s important to look for safety features.

Most manufacturers equip space heaters with auto-shutoff switches, cool-to-the-touch exteriors, and overheat protection. These features have considerably lowered fire risks.

Energy Efficiency

It’s essential to look at the heater’s efficiency level when making a purchase. This is important if you want to save energy and keep utility bills low.

Although portable heaters aren’t stamped with standard efficiency ratings like EER or SEER, it’s very simple to calculate the heater’s operating cost. Additionally, to maintain low bills, pick an energy-efficient heater that suits your environment and the surface area.

Most conventional heating units come with an adjustable thermostat, eco-modes, low-wattage, and programmable timers. Therefore energy efficiency should not be an issue.

Noise Levels

Some electric, wall, and space heaters for small rooms generate more noise than other variants on the market. Therefore, you should never overlook the stamped decibel rating, especially if you plan to place it in your bedroom.

For ultra-quiet operation, consider buying oil-filled radiators, fan-forced, and tower heaters. Their sound level is so low that you won’t even know if they are active.

Other Features
  • Thermostat options:
    You can set a temperature, and the heater will ensure that it remains maintained. Every time there is a lapse, the unit activates and cranks up the heat till the indoor temperature is raised to a pre-defined level.
  • Hardwiring/plug:
    Some units require hardwiring, while others are plug-in, ready to go heaters
  • Timer:
    You can preset your unit’s on/off functions—a highly convenient option to conserve energy.
  • Smart operation:
    It allows you to manage and monitor room conditions, set the desired temperature, and switch it off/on when you need it.
  • Warranty:
    Warranty values vary for small units. Typically, the offered coverage is anywhere from one to five years.

One last thing you want to consider before making the purchase is how much money you’re willing to spend on your ideal heater. It’s a given that the more features a heater has, the higher its price would be.

Not only special features, but the price also depends on its heating power and model. Nevertheless, you can find a useful small room heater for anywhere between $20 and $100.
