Benefits of Portable Heaters
- Easy installation: Most portable heaters are extremely easy to use, unlike other types of heaters available on the market. Simply plug in your heater and it should start working immediately.
- Efficient: Portable heaters are known for their efficiency and are an environmentally friendly option. Electric portable heaters are 100 percent energy efficient, meaning that all the electricity used is converted directly into heat.
- Versatile: Portable heaters are an extremely versatile product. They’re great to use in a variety of situations and in several different areas of your home. Electric heaters can be used for emergencies, but they can also be used to heat up small rooms like your office, basement, den, garage, or shed.
Types of Portable Heaters
Fan portable heaters feature electric coils that are used to generate heat. The warm air is then blown across the room via a fan. This type of portable heater is ideal for small rooms such as offices, bedrooms, dens, basements, sheds, and garages. One downside of this type is that the heat can easily be lost if you open a door or let a draft into the room.
Convector portable heaters, also known as convection heaters, feature an internal heating element similar to fan heaters. But instead of circulating the warm air via a fan, they wait for hot air to rise and be replaced by cool air, which then gets heated. They’re much slower to heat up than fan heaters, but convector units distribute heat more thoroughly.
Oil-filled portable heaters use an electrical current with thermal oil, heating the oil and circulating it around the heater, similar to water in a radiator. Oil-filled units are heavier than other types of heaters, so they’re probably the least portable of the three types. But overall, they’re the most reliable portable heaters and stay warm for the longest time, even after they’re turned off.

Portable Heater Pricing
- Under $30: Portable heaters in this price range are an excellent value purchase. They are often a small, compact size, but will deliver a sufficient amount of heat for small rooms like offices, bedrooms, dens, sheds, garages, and more.
- Between $30 and $70: This is the most common price point for portable space heaters. Products in this price range usually have enough heat to warm small to medium-sized rooms. They often come with additional features like remote controls and safety modes.
- Over $70: Portable heaters in this premium price range are of the highest quality. They typically can heat larger rooms or areas, and feature high BTU. These heaters contain a number of safety features and LED indicators, and can be used in both indoor and outdoor spaces.
Heating capacity is one of the most important considerations when shopping for a portable heater. It’s important to know the size of the space that the heater will cover before making your purchase. In general, the higher the wattage rating, the greater the heating power. This is not true of all models, so make sure to check the specifications before buying if you’re looking to use it in a certain area of your home.
Although many portable heaters are quite energy efficient, it’s important to check and compare efficiency ratings before making your final purchase. It's necessary to choose the proper heater for your home and space so that you don't see a spike in your electric bills. Some models are even available with special features such as energy-saving modes, adjustable thermostats, low wattage, and programmable timers.
If left unwatched, portable heaters can be a fire hazard. Many heaters feature cool-to-touch surfaces and include automatic shut-off modes in case the heater is accidentally tipped over. Overheat-protection mode is another important feature that’s included with many portable heaters. Always read your product's instruction manual and make sure you take all safety precautions before using it.
- Warranty: The type of warranty is an important consideration when purchasing a portable heater. A longer warranty shows that the manufacturer has faith in its product and stands behind its services. Most portable heaters come with some type of warranty. It’s recommended to at least have a limited warranty, but make sure to double-check the warranty information before buying.
- Noise Level: As with most electrical appliances, portable heaters will emit some type of noise while in use. But some models will be much louder than others. Take into consideration the reviews and ratings before making your purchase. If you’ll be using it in your bedroom or office, you may want to opt for one of the quieter options available. Some portable heaters include quiet modes that can be switched on with the touch of a button.
- Size: If you’re going to be transporting your portable heater to various rooms around your home, then size is an important consideration. You want to make sure to buy a model with wheels, or one of the lightweight options with convenient carrying handles, if you’ll be moving it often.
