The Best Low Watt Fan Heaters To Buy In 2024
AT A GLANCE
Choosing a good fan heater that is also energy-efficient and thus cheap to run can be challenging, because usually you end up sacrificing quality or performance for that lower power output.
We’ve taken the hard work out of your search and selected 5 low watt models for you to choose from, which you can check out below.
There are, however, a few facts about fan heaters that you should know before making your purchase.
What is a fan heater and how does it work?
A fan heater, sometimes called a blow-heater, uses a fan to circulate and blow out the hot air generated by the device. With this method, air is distributed more fairly around the room.
Can a fan heater be used as a fan?
Many, but not all, fan heaters come with the ability to use the fan element as an actual fan for the purposes of creating a cool breeze. You should double check that the model you select has this capability.
How many watts is a fan heater usually?
The average fan heater is 1500W. Most models on the market will be at least that, though with a thermostat, you can reduce or increase this quite considerably.
How much electricity does a fan heater use?
The fan-only aspect doesn’t use much electricity. But as a heat-producing appliance, electric fan heaters use a lot of electricity and are quite expensive to run, especially compared to gas-powered heaters.
The average 1500W fan heater will cost you around $0.35 per hour to run. Depending on where you use it (i.e. in very cold climates or large rooms), you might need to keep it running for several hours just to stay warm. This would set you back a few dollars a day during the winter months.
Thus, it’s important to choose your fan heater carefully; choose a fan heater with low running costs to ensure that it won’t break the bank when you turn it on.
Choosing a small fan heater with a thermostat
It’s almost impossible to find a fan heater that’s below 1500W at its highest setting. However, a small fan heater with a thermostat allows you to reduce temperatures/wattage, sometimes going as low as 600W.
This type of heater is ideal, as you can switch temperatures whenever more/less heat is required.

What’s the downside to buying low wattage fan heaters?
The obvious drawback is that lower wattage means less heat, and thus you may end up spending the same amount of money you would have with a higher wattage heater, as you’ll have to keep it running longer.
Or, worse still, you may find that they simply cannot generate enough heat no matter how long they run for.
