Top 5 Best Space Heaters of 2021 - Best for Large & Small Rooms

Updated: Nov 24th, 2021

Electric space heaters run on electricity, and electricity is not exactly cheap. For sake of the environment as well as your wallet, it makes sense to get the most energy-efficient space heater you can find.

What are the most energy-efficient space heaters?

Well, they are simply units that:

  1. Provide us with as much heating output as possible
  2. For the lowest electricity expenditure.

If you need to heat up indoor spaces safely and effectively, buying one of the most energy-efficient space heaters makes a whole lot of sense.

The truth is that because a new type of heater has hit the market that big energy companies are trying their best to stop as it is saving Americans THOUSANDS of dollars on their electricity bills while ALSO providing them with comfortably hot homes.

To help you out, we decided to buy, review & test 2021’s most popular and efficient heaters on the market to see which ones are truly the best.

Our testing revealed that buying a heater from a big brand can actually be a waste of money as they’re already established on the market and don’t need to “fix what’s not broken”.

So it seems the winner is from a smaller company that figured out they had to re-invent the wheel to beat the competition.

And they did, in every last aspect: Safety, User control, Quick heating, Silent operation, Portability, Aesthetics, and Price.

Why Is Alpha Heater Our #1 Pick of 2021?

We bought and tested them all.

The best space heater of 2021 is surprisingly won by a relatively small brand, Alpha.

Tech, price/quality ratio and customer support all came in first.

Its strong heating power were also unmatched.

It passed every test with flying colors, including the most important one – keeping our homes warm for an affordable price.

Under our controlled testing, the Alpha Heater rapidly heated up a cold, 55 degree room to a warm 79 degrees in just two and a half minutes.

This was no box room either, although it will be perfect for that. We ran our test in a 375sqft living room, so that level of warming was much more than we expected.

For results like that, you’d think it would be burning through the electricity at a rapid pace – but surprisingly, it was the exact opposite. Alpha Heater is the most energy efficient space heater we tested, making it incredibly cheap to run.

With a portable heater this good, you may actually worry about rooms becoming TOO hot, but thankfully the Alpha Heater has multiple settings to suit any room size or temperature preference. It was so easy to get the desired temperature we felt comfortable at.

Portability is another area where Alpha Heater scores top marks. It’s so small you can easily place it in rooms of all sizes. It would be perfect to give to a child moving into a new apartment or dorm room, as it’s so light and easy to transport. 

But what shocked us most was the price – it’s incredibly affordable for something that works so well. And considering it comes with a full money-back-guarantee – Alpha Heater is a no brainer.

If you want a tiny space heater that keeps your home warm and comfortable at all times – the Alpha Heater is our #1 choice.

“Not only did I save a bunch of money, but what I loved about this was you could warm up a room literally in a couple of minutes. It was always instant-warm. Never had to wait for the big, noisy central heating system or oil-filled radiant heater anymore!”
