Space heaters are great for a little extra heat on your feet in a home office or to keep things from freezing over winter in your new RV. Some can even be used for camping or in a tent.  They are a cheap, easy means of providing heat for smaller spaces without relying on excessive amounts of gas.

A space heater will be useful as long as you have a reliable electrical connection, but there are many to choose from. Our list of the 10 Best Space Heaters is designed to help you narrow down your options and our Buyer’s Guide will lay out some of the most important factors in selecting a new space heater.

Buyer’s Guide

Albert Marsh is widely recognized as “the father of the electrical heating industry” for his discovery of Chromel, which is an alloy made of one part Chromium and four parts Nickel (3). Before his discovery, low-cost cast iron radiators were the common method of heating homes with relative efficiency.

Since Marsh’s discovery at the beginning of the 20thcentury, we have continued to refine and improve home heating technology. Space heaters are just one example, but there are so many to choose from and it’s important to choose one that makes sense for the space you want to heat.

In an effort to aid in your decision, our Buyer’s Guide will focus on three main characteristics that help to distinguish heaters from one another. Those characteristics are size and coverage, fuel types, and important features.

Size and Coverage

The first and arguably most important consideration when selecting a new space heater is the size of the space you wish to heat. Large family rooms require more heating capacity than a small office or garage apartment. It’s also important to avoid buying a heater that’s overly large for a given space, as this will only lead to wasted energy and/or an unnecessarily high electric bill.

Generally, 1500-watt space heaters are great for heating rooms up to 175 square feet. On their low setting, when most of the heaters above put out 750-watts of heating capacity, they will heat 100 square foot space. The image below gives you a great idea of how much space you can heat with a given wattage or BTU rating.

Fuel Types

Space heaters can largely be separated into gas and electric options. Within the category of electric heaters, though, there are convection, infrared, panel, and radiation heaters. Convection heaters are generally regarded as the most energy efficient and commonly used means of heating an enclosed space.

Infrared heaters are great for providing direct heat to specific objects or people they are pointed at but don’t tend to disperse heat throughout a room as well. Panel heaters feature the best attributes of convection and infrared heaters while radiation heaters are best for leaving in a room for a long time because they utilize natural air circulation to disperse warmth.

Gas heaters are largely used with either liquid propane or natural gas. Liquid propane allows for the heater to remain portable and not connected to a gas line when not in use. Natural gas heaters typically require professional installation because they need to be connected to a dedicated gas line. The major benefit of gas space heaters is that they will continue to be useful during a power outage.

Important Features

The heaters detailed above offer a variety of features. Sorting through them to find the most important ones is an important part of the buying process. For starters, it’s hard to argue against buying a space heater that offers an auto shut-off feature, as safety should be the primary concern when buying any heating device. An auto shut-off will help to prevent overheating and fires caused by improper use.

Another important feature that many buyers don’t consider is the length of a heater’s power cord. Because it’s never safe to use a space heater with an extension cord, a heater with a longer cord will give you the freedom to place it exactly where you need it, especially in rooms that lack a good number of available power outlets.

The last feature we’ll mention today is a remote control. Although this isn’t necessarily an imperative feature, remote control operation will allow you to stay comfortably warm and snuggled in bed while adjusting or re-adjusting the settings of your space heater.

Frequently Asked Questions

Space heaters are extremely valuable for providing both concentrated heat on your cold toes in the winter or for dispersing heat throughout a room that otherwise wouldn’t have heat. They can, however, be dangerous if not used and cared for properly. This list of Frequently Asked Questions will help you gain more essential knowledge about space heaters.

What is ‘BTUs’?

BTUs are ‘British Thermal Units’. They measure how much heat a space-heating unit puts out. A heater’s BTU rating determines how much space it can heat safely and effectively.

Are space heaters dangerous?

Some statistics suggest that an average of 40% of home fires are caused by misuse of a space heater (4). The most common transgression is for space heaters to come in contact with flammable materials, so the simple answer is that, if used improperly, space heaters can absolutely be dangerous.

How do I ensure safety when using a space heater?

For starters, never operate your heater near flammable liquids (gasoline, paint, alcohol, etc.). Also be sure not to leave the heater unattended for long periods. Never place it near curtains or use an extension cord to connect a heater. Be sure to replace damaged parts on a heater rather than using it when it’s not “100 percent.”

Can you explain ‘convection heating’?

Convection heating is a common method used by space heaters. By circulating convection currents across a heating element (such as an electric coil, oil, or electric wire, these heaters create an overall warmth in your space.

Can I use a space heater as my main heat source?

In most homes, a single portable space heater won’t create enough warmth to heat the entire space. However, whether a space heater alone will be sufficient in your case will depend on environmental conditions, personal preferences, and housing construction.

Why does it smell like something is burning when I turn my heater on?

Many newer models will give off a slight burning odor when they are first used. This should go away after a while. Radiant heaters can sometimes burn up dust particles in the air, which will give off a noticeable scent. Additionally, some heaters can produce a burning odor as dust builds up on the heating element. These odors are generally not offensive, hardly noticeable, and typically temporary.


A quality space heater means the difference between uncomfortable winter nights and bearable conditions. In some situations, they can also spell the difference between frozen RV pipes and the ability to use all of your essential systems. We hope this article has helped you find a space heater that’s right for you and we wish you Happy Heater Shopping!
