Alpha Heater Test Results - the Most Energy Efficient & Poweful Space Heater Under $100
We bought and tested them all.
The best portable heater of 2023 is surprisingly won by a small brand, Alpha Heater.
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, 54 degree room to a warm 75 degrees in just 4-5 minutes.
This was no box room either, although it will be perfect for that. We ran our test in a 325sqft 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 portable space 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. You could also attach a mobile power bank and take it on with you.
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 small space heater that keeps your home warm and comfortable at all times – the Alpha Heater is our #1 choice.
