How Big Of Generator To Run Furnace

Okay, let's talk generators! Not the most glamorous subject, I'll admit. But trust me, knowing how to choose the right-sized generator to keep your furnace humming during a power outage? That's pure, unadulterated peace of mind. And who doesn't want more of that in their life?

Imagine this: the lights flicker, the power goes out, and a chill starts creeping into your home. But you? You just calmly fire up your generator, and your furnace kicks in, blasting warm air. You're a superhero of home comfort! Think of it as your personal 'winter is coming' preparedness plan.

So, how big of a generator do you need? Good question! Let's break it down.

Understanding Your Furnace's Power Needs

First, you need to know your furnace's starting wattage and running wattage. What are those? I'm glad you asked! The starting wattage is the amount of power it takes to initially kick the furnace on – it's like a little jolt. The running wattage is what it needs to keep purring along once it's going. Think of it like getting a car moving (starting wattage) versus keeping it at a steady speed (running wattage).

Where do you find these numbers? Check the nameplate on your furnace. It's usually a sticker or metal plate with all the important information. Look for "watts" or "amps." If you see amps, don't panic! You can easily convert amps to watts using this simple formula: Watts = Amps x Volts. Most household circuits are 120 volts, but double-check to be sure.

Important note: Furnaces with electronic ignition require electricity. Older furnaces might use a pilot light, but most newer models rely on electronic components to ignite the gas. This is what requires the generator's power! So, even with gas heat, you still need electricity.

Sizing Your Generator: Don't Be a Wattage Wimp!

Okay, you've found your furnace's wattage. Now, here's the golden rule: Don't skimp on generator size! Always get a generator that can handle the starting wattage plus the running wattage of your furnace. In fact, it's always better to err on the side of a slightly larger generator. Why?

Because you probably have other things you want to power during an outage, right? Lights? Refrigerator? TV to watch your favorite show while staying warm? (Priorities, people!). Add up the wattage of those other essential appliances and factor that into your generator size calculation.

A good rule of thumb is to add at least 20% more wattage than your total estimated needs. This gives you some headroom and prevents your generator from being constantly overloaded. Overloading can damage both the generator and your appliances – nobody wants that!

Example: Let's say your furnace needs 1200 starting watts and 600 running watts. You also want to power a refrigerator (150 starting watts, 75 running watts) and a couple of lights (60 watts each). That's 1200 + 600 + 150 + 75 + 60 + 60 = 2145 watts. Add 20% buffer: 2145 x 1.20 = 2574 watts. So, you'd want a generator that can produce at least 2574 watts.

Choosing the Right Type of Generator

You've got your wattage number. Now, it's time to choose the type of generator. You've generally got two main options:

• Portable Generators: These are the most common and affordable option. They run on gasoline or propane and can be moved around easily. Perfect for occasional power outages.
• Standby Generators: These are permanently installed and automatically kick in when the power goes out. They're more expensive but offer ultimate convenience and peace of mind. Think of it as the Rolls Royce of generators.

For just running a furnace, a portable generator is often sufficient. However, if you want whole-house backup power, a standby generator might be a better investment.

Safety First! (Seriously!)

Before I let you go, a word on safety. Generators produce carbon monoxide, a deadly odorless gas. Never, ever run a generator indoors or in an enclosed space like a garage. Always operate it outdoors in a well-ventilated area. Install carbon monoxide detectors in your home and test them regularly.

Also, be sure to follow the manufacturer's instructions for safe operation and maintenance. This isn't just boring reading, it's essential for your safety and the longevity of your generator.

Choosing the right size generator for your furnace (and your peace of mind) doesn't have to be daunting. A little research and planning can make all the difference when the power goes out. So, get out there, check your furnace's wattage, and get ready to be the hero of your home this winter!

Now, armed with this knowledge, go forth and explore the exciting world of generators! Think of it not as a chore, but as an investment in your comfort, security, and maybe even a little bit of bragging rights when the next power outage hits. You got this!
