Best Surge Protector for Space Heater 2021

Best Surge Protector for Space Heater

We are constantly looking for ways to improve our carbon footprint. One way is to use space heaters to heat individual rooms that are being used, rather than the whole house. Space heaters have their advantages but you have to follow their safety instructions. And getting the best surge protector for the space heater is a great decision.

Heating equipment caused 56,000 home fires in the US between 2009 and 2013. This caused 470 deaths. 32% of household fires are because of space heaters. Space heaters should never be plugged into a power strip. Only into the wall or a surge protector.

Get a Surge Protector for your safety

Sometimes spikes in the voltage come through our AC outlets. A surge protector will send this extra voltage away from your appliances and to the ground.

Space heaters need a lot of electrical power, so higher joule protection is better. We will also look at other safety features to help protect your home.

Some features include fire-resistant materials, built-in circuit breakers and outlet covers. These covers protect outlets from dirt and dust that could start a fire.

If you are looking for a ‘best buy’ we recommend the Powrui. Although it doesn’t have a cable, it is ideal for someone who is only looking for a surge protector.

It doesn’t have the highest amount of joule protection but you won’t be able to plug more than one other thing in the outlet (except for USB chargers). You will also get two in the pack so you have an extra surge protector for other appliances.

The i-BRIGHT ticks most of the right boxes for safety except the 600v clamping voltage. This is a little high for our liking. It is a great choice if you love to have the latest technology.

The Tripp Lite is a good option if you are looking for high joule protection, clamping value and response time. It doesn’t have any USB ports but it does have an attractive price. It also has a lifetime warranty and a $150,000 connected equipment warranty. Because of this, the Tripp Lite is our all-round winning surge protector for space heaters.
