Top 10 Indoor Space Heaters

Why Get a Space Heater?

A space heater is a cost-efficient way to keep a room or a portion of a room warm. Adding a space heater to your bedroom will help you stay comfortable throughout the night without turning the heat on.

If you have a room that is not connected to your main heating system, you definitely need a space heater. These appliances also help you reduce your energy bills when used as an alternative to your furnace.

What to Consider When Shopping For Space Heaters

You need to pay attention to the wattage rating of a space heater to determine how much electricity the appliance will use and how efficient it will be. As a rule of thumb, you should get a space heater with 10 Watts per square foot.

You will also need to look at BTU ratings. BTU stands for British Thermal Unit and basically indicates how many BTUs/hour the appliance will add to the air. A lot BTU rating means your space heater will have to run for a long time to warm up a room and a high BTU rating means you will need to constantly turn the appliance on and off since the air might heat up too quickly.

Look for energy-efficient products, think about getting a space heater with an adjustable thermostat, a programmable timer, and other features you will need. Overheat protection and an internal switch that turns the appliance off if it gets knocked down are other features to look for.
