How to Protect Your Furnace from Power Surges

When protecting your furnace against power surges, it is important to take a layered approach by combining whole-house and point-of-use surge protectors.

Let’s discuss both and their uses

Whole-house surge protection

Whole-house surge protection guards the wiring of all your electronics, from light fixtures to appliances, from harmful surges.

Most of these surge protectors can stop a 40,000-amp surge, which means you are protected against just about anything except a direct lightning strike. 

There are two different types of whole-house protectors:

Type 1 is installed between the power line in the street and your home’s electric meter. These protectors are a primary line of defense against external surges, but they will take more effort to install as you will need the assistance of your power company as well as necessary permits.

Type 2 is more commonly used, and it is installed directly in your breaker panel. It is often referred to as a branch panel because it filters the power from the service panel into the circuits of your house. 

The significant benefit of these panel protectors is that they ease external and internal surges such as those created when your air conditioner or furnace is switched on.

Just think about how many devices you have in your home. You can’t remember or be expected to attach surge protection to each and every item, so you need this blanket security.

In an ideal world, you would have the 3 primary types of surge protectors installed in your home for absolute protection, with the third being point-of-use surge protectors.

Point-of-use surge protectors

Installing a point-of-use surge protector is an excellent idea not only because it protects your furnace, but also because it adds another level of protection. And the more protection, the better.

The fact of the matter is that whole-house surge protectors cannot always contain the full force of a strong surge, so, in essence, whole-home surge protectors do their best to save you from the monstrous power surges and a point-of-use system to give you that extra line of defense.

These point-of-use protectors are especially important in the case that many of your electronics share the same circuit, so if you plug the vacuum into a circuit shared with your television, these other devices could still experience a power surge if they are not connected to a surge protector.

There are different types of point-of-use systems.

The most popular variety is the kind that you plug into any given electrical outlet. These devices are usually in the form of power strips where you can plug your various devices into it. 

The effectiveness of these protectors is based on the clamping voltage (how much of a surge has to hit them before they start absorbing the electricity to protect your devices). Look for a protector that can take 600 to 700 joules.

A second favorite type of point-of-use surge protector is in the form of an actual electrical outlet. They act in the same way as the power strip variety but are beneficial for use behind bookshelves or furniture when you have a lot of electronics and not a lot of room for the sometimes awkward strips.

You should, at a minimum, install a point-of-use surge protector.

Install your surge protection with a company you can trust

More important than simply having proper surge protection is ensuring that you are having it installed correctly. Because the only thing worse than not having protection is having it and still seeing your furnace fail when you need it the most.
