The Top 10 Best Rated Space Heaters of 2021

Last updated on January 11, 2021

Looking for a space heater for your home? These space heater picks for the top 10 best-rated heaters of 2021 will help you choose.

► Our top choice: this ceramic tower heater.

A space heater has saved me a lot of times when a heated blanket couldn’t. I used to live in an apartment with central heating, but they would always delay turning it on until the cold was unbearable. A small fan heater would only have to run 3-4 hours on a medium heat setting to make it comfortable. It barely made a dent in the electricity bill. It made me happy.

But which space heater is the best? That’s a good question, and we aim to answer it. We’ve gone ahead and examined hundreds of options available to find only the best heaters for different uses. So whether you need a heater for your home, office, bedroom, or you need a mini portable version, you’ll find everything on this top list.

We cover these three most popular types of electric heaters:

  • The ceramic heater uses a ceramic heating element and a fan to distribute warm air.
  • The oil heater is a conventional radiator that uses electricity to heat an oil-filled buffer. It doesn’t use a fan and radiates heat.
  • The infrared heater uses an infrared panel to heat objects instead of air.

All of these types of heaters have their pros and cons. The best is only determined by the quality of the product, extra features, and its use case.

For example, radiant heaters are silent, but a ceramic heater with a fan is much faster. Radiant heaters are more efficient in smaller rooms while fan heaters can quickly fill up larger space with warm air.

The boring mandatory note: we get a commission for our shopping links, and they cost you nothing extra. We hope you’ll find them useful.

FAQ

What is the best kind of space heater?

There’s no one size fits all. Each type of heater has its pros and cons. Radiant (oil-filled or infrared) heaters are the quietest, while ceramic heaters are the fastest. Units with programmable thermostats are the most efficient.

Which type of space heater is cheapest to run?

Infrared space heaters tend to be cheaper to run compared to other radiant or fan heaters. It’s due to their nature to heat objects directly instead of filling up space with hot air.

How much does it cost to run a 1500 watt heater for 24 hours?

If you run a 1500 watt heater for straight 24 hours on a full heat setting, that will cost 1.5x24xkWh. So if your electricity rate is $0.1/kWh, it will cost $3.6/day. However you’re unlikely to use your heater so much. Programmable thermostat and eco-friendly features cut the cost even more. So it will likely cost you just a fraction of that.

Is infrared or ceramic heater better?

An infrared heater will be cheaper to run in a small space than a ceramic heater. It will be silent too. However, a ceramic heater will heat larger space faster. Therefore which is better depends on case by case basis.

What type of space heater is most energy efficient?

Look for a space heater with eco-friendly options (adjustable thermostat). Regardless of its type, a high-quality modern heater will be packed with features that enable it to be as energy-efficient as possible within its means. It also depends on its use and the size of the room.

What is the cheapest way to heat a room?

Insulation is the key to cheaper heating. So no matter what space heater you use, its efficiency will greatly depend on how well insulated is your home.
