There are a variety of electric and gas space heaters available in the market. We will discuss a few of them in the following sections.


Types of Electric Space Heaters

Convection Heaters

These space heaters are the most energy-efficient and viable option for larger living spaces. A convection heater works by efficiently heating the surrounding air. Although these heaters may take a little more time to heat up, the warmth will last long after the heater is turned off. 

Many models of convection heaters also have a fan to provide additional heat circulation, which is ideal for many enclosed spaces.

Panel Heater

Panel heaters are quite similar to centralized heating systems, and efficiently combine the processes of radiant and convection technology. One of their main benefits is that they can reach peak power reasonably quickly and generate evenly distributed heat.

Types of Gas Space Heaters

Natural Gas Heaters

These heaters require professional installation with a gas hookup. Keep in mind that a few models may not have any venting. It is because they come with an automatic shut-off switch in situations where air quality gets poor.

Propane Heaters

You can light a propane heater with a match, or it may need electricity for ignition. Propane heaters are available in various sizes and could accommodate different amounts of fuel.

Due to the various types, controls, and features, finding the best space heater could be confusing for most buyers. We know you can get overwhelmed and confused by the broad selection of space heaters in the market; it is why we have compiled a list of top five contenders to make the buying decision easier and simpler for you.

What Features to Look out for when Choosing a Space Heater?

Consider the following features when buying a space heater to make a more informed decision.


Space heaters have BTU measurements and watts output. Therefore, it is always helpful if you know both the numbers. You could quickly determine the relevant BTU output by if you multiply the total wattage you require by 3.41 (one watt is equivalent to about 3.41 BTUs). So, if you need 3,000 watts for heating your space or home, multiply 3,000 by 3.41, and you will get 10,230 BTUs.


Do you need a portable heater or portability does not matter? If you are planning to use your space heater in the same space or room at all times, it might be more convenient and safer to install a baseboard or wall mounted space heater. In contrast, you will need to have a light and portable heater that you can take from one room to another to provide supplemental heating in all the living rooms in the home.

Overheating Safety

If you do not monitor your space heater adequately, it can quickly become a fire hazard. So, it is vital to consider all the safety features. To considerably cut down the risk of fires, a majority of manufacturers now equip electric space heaters with advanced cool-to-the-touch surfaces and a variety of sophisticated safety features to ensure secure and safe operation.

Many space heaters have internal switches that can automatically shut the power off if you accidentally tip over or knock down your space heater.  The switch works as a smart sensor and automatically shuts the heater down if the internal elements reach an unsafe temperature.


A thermostat helps maintain the temperature you have set and saves you the hassle and inconvenience of turning your heater off and on as your room temperature varies. Heaters that have multiple output settings tend to conserve energy as they let you choose the minimum heat setting to keep your room warm and comfortable.

Energy Efficiency

In case conserving energy matters to you and you need to keep heating costs low, it is always better to compare efficiency before you choose a space heater. Although portable electric and gas heaters do not have a standard level of energy efficiency such as the EER ratings you can find on most portable AC systems, you can quickly calculate heater operating costs with a simple formula.

Noise Level

Like a majority of electrical appliances, most space heaters usually produce some noise during operation. Keep in mind that, however, some models generate more sound compared to others. Consider buying a non-fan-forced model like an oil-filled radiator or a baseboard heater for noiseless operation in quieter environments such as your bedroom or office. 


When purchasing anything new, it is vital to take all of the relevant factors into account. However, you must also consider those features that you require the most. And when it comes to heating your home or office, the only suitable and reliable option for most people is a dependable space heater. An ideal space heater will be lightweight, energy-efficient, safe and comfortable.If you keep the above features in mind, you will buy a good product that is well-suited to your needs.

Finally, although it might seem like common sense, you must supervise small kids and pets at all times when your space heater is running. Do not leave your space heater unattended if you are exiting your room or if aren’t in the house. It is vital that you must turn off and unplug your heater.
