Best Surge Protector for Space Heater | Comparison of Top 5 Surge Protectors

Best Surge Protector for Space Heater

One of the most frequently asked questions about space heaters is whether or not you can use them with surge protectors. Now, let’s look at it closely.

A surge protector is a device that safeguards electrical appliances from power surges and spikes. Lightning strikes, short circuits, power outages, and tripped circuit breakers can generate a voltage spike. Voltage spikes can also come through AC outlets or sockets.

These surges transfer excess energy to equipment, which might cause them to malfunction or spark fires. Surge protectors divert the excessive voltage from these appliances to the earth.

They comprise electrically resistant materials. When it undergoes a voltage spike, the resistance lowers the surge to normal levels.

Surge protectors can be single or multi-outlets:

  • Single outlet surge protectors plug into a wall outlet, and your device plugs into it.
  • Surge protectors with multiple outlets are similar to power strips. The protection integrates into the strip’s socket, and devices connected to it are safe from spikes.

The resistant components of these devices are not indestructible. They can withstand a certain number of joules printed on the package. Once the protector has handled the specified joule rating, it will stop providing surge protection.

Unfortunately, most surge protectors do not indicate when it’s no longer working, but the more costly models come with an indicator light that turns on when it is no longer functional. Others may turn off when the suppressor reduces.

They must be replaced every two years or after a significant impact like a storm or power loss.

Surge Protector Or Power Strip?

People use the terms ‘surge protector’ and ‘power strip’ interchangeably.

Plugging a space heater into a power strip is not recommended by manufacturers, fire agencies, or the Department of Energy.

You should connect your space heater to a surge protector or a wall outlet because space heaters use a significant amount of energy, and inexpensive power strips can not handle the load. Overheated power strips may result in disastrous electrical fires.

If you must use a power strip, make sure it is heavy-duty with at least a 14-gauge wire. Also, consider the amperage rating because if you plug a space heater into a power strip with a low amperage, you may blow it.

So, surge protectors require heavy-gauge cable and sufficient amperage.

It’s worth noting that amps and joules are not the same. Your surge protector may be able to handle 3940 joules in the event of a spike, but it will most likely still maintain a 15A rating.

Failing electrical accessories are uncommon, especially when it involves a space heater. The lifespan of electrical coils or ceramic plates in space heaters is reduced gradually by spikes, which are the primary reason for their replacement.

Always place a surge protector between the power supply and your devices to avoid burning your space heater and other electrical equipment.

Here is a resource to help you overcome electrical disasters when you shop for the best surge protector for a space heater.
