Product FAQ
Below we answered some of the most frequently asked questions about the most efficient space heaters so you can know the information needed to understand our analysis and pick the right heater for you.
What Is a Space Heater?
They are heaters, commonly running on electricity, that have been specially designed to heat certain specific areas, as opposed to entire homes as with central heating systems. Having a space heater is primarily for heating that room, making them perfect for enclosed spaces.
Different Space Heaters
Finding the most efficient space heater isn’t as easy and as straightforward as you may have thought as there are several types of space heaters on the market. Below we analyzed the three most popular options, so you know what you are buying.
Convection heaters
The first and probably most popular option on our list, convection heaters are specially designed to heat the room by generating warm air that rises quickly to help increase the temperature in that room. As the hot air rises, the cool air plummets to the floor, forcing the air to circulate and thus heating a room without causing it to become overly stuffy or dry.
Radiant heaters
Another option is radiant heaters, also known as radiative heaters. These heaters are specially designed to heat specific objects or people in a room instead of the air. They are placed directly in front of a person instead of anywhere in the room and work extremely quickly, so if you are looking to get heat fast, these may be the best option for you.
Combi heaters
Combi heaters are a combination of convection space heaters and radiant space heaters as they help to distribute warm air around the room using a fan while generating direct heat at the same time. They are often the most expensive type of heater, but they provide a balanced form of heat distribution which is usually well worth the price.
Why Do You Need the Most Efficient Space Heater?
The reason you need the most efficient space heater is so you can save energy and money, easily control the temperature of your room, get rid of cold spots, and heat your room quietly and conveniently.
What Should I Look for in a Space Heater?
First, consider how reliable the product is as safety should be at the top of your list of priorities. Specifically, with Radiant Heaters, make sure they are put somewhere nobody will touch them by accident as they can cause burns upon contact.
Further, a bad space heater can be a fire hazard or lead to a stuffy and uncomfortable room. Finally, consider what you are trying to heat and pick your product accordingly. If you want a warm room, a convection heater may be your best bet.
If you will warm yourself, a radiant heater is ideal. And for the best of both worlds, go for a combi.
How Can I Maximize My Heater’s Efficiency?
Radiant space heaters are considered the most efficient heater for your home, but there are things you can do with many space heaters to help you save even more electricity with them.
We recommend turning the heat to low once you have reached a comfortable temperature, keeping doors and windows closed to prevent hot air from escaping, only warming rooms in use and trying to wear warmer clothing.
The Verdict
The most efficient space heater on our list is the Sure Heat 30,000 BTU Blue Flame Dual Fuel Gas Space Heater, but for those looking for a cheaper or non-gas option we would recommend the Lifelux 1500 Watt 110 Volt 15 Amp Revolutionary Infrared Electric Heater.
