Gas and oil furnaces use less electricity. They rely on fuel. But they have electrical components. Think fans and ignition systems. These require power. Typically, 300 to 600 watts suffice. Here is what they need:
- Ignition: 200 watts
- Fan/Blower: 100 – 400 watts
- Controls: minimal
Ensure generator capacity matches your furnace’s power needs. A stable power source is crucial. It keeps your home warm and safe.
Selecting The Right Generator For Your Furnace
Winter storms often bring power outages. A reliable generator can keep your furnace running. This guide helps you choose the best one for your home.
Calculating Wattage Requirements
Know your furnace’s wattage needs before buying a generator. This ensures enough power during an outage. Start by checking your furnace’s manual. Look for the starting and running wattage. Add extra watts for other essentials. This total is your minimum generator power requirement.
- Starting wattage is higher than running wattage.
- Include a buffer for additional appliances.
Add more rows as needed
| Appliance | Starting Wattage | Running Wattage |
|---|---|---|
| Furnace | xxxx W | xxxx W |
| Refrigerator | xxxx W | xxxx W |
Portable Vs. Standby Generators
Choose between portable and standby generators. Portable ones are cost-effective. They can power a furnace and a few other items. Standby generators are more expensive. They start automatically and can power an entire home.
- Portable generators are less expensive.
- Standby generators offer convenience and power.
Consider your home’s size and power needs. Also, think about the installation space. This will guide your choice.

Connecting Your Furnace To A Generator
Power outages can leave homes cold, especially in winter. Connecting your furnace to a generator keeps your home warm. This guide shows how.
Step-by-step Connection Process
- Turn off your home’s main power supply.
- Find your furnace’s power cord. It looks like a big plug.
- Get a heavy-duty extension cord. Make sure it’s long enough.
- Plug one end of the extension cord into the generator.
- Plug the other end into your furnace.
- Start the generator. Make sure it’s outside your house.
- Check if the furnace starts. Feel the warm air coming out.
Using Transfer Switches
A transfer switch makes connecting safer. It’s like a smart switch.
- It stops power from mixing. This keeps your house safe.
- It lets you power your furnace without long cords.
- A professional should install it. They know how to do it right.
Follow these steps for a warm house during power outages.
Safety Precautions When Using Generators
Using generators safely is key, especially with furnaces. Let’s dive into safety precautions when using generators. These steps keep you and your home safe.
Proper Ventilation To Prevent Co Poisoning
Generators produce carbon monoxide (CO), a dangerous gas. You can’t see or smell it. Proper ventilation prevents CO poisoning. Always use generators outside, far from windows, doors, and vents. This keeps the air in your home safe.
Keeping The Generator Dry And Grounded
Generators must stay dry and grounded. This prevents electric shocks. Use generators on a dry surface under an open, canopy-like structure. Never touch the generator with wet hands. Grounding the generator is also crucial. Follow the manufacturer’s instructions to properly ground. This protects you from electric hazards.
- Never use generators indoors or in garages.
- Install CO detectors in your home for extra safety.
- Check the generator’s manual for grounding instructions.
By following these steps, you ensure safe use of generators with furnaces. Safety first always protects your home and loved ones.
Maintenance Tips For Generators And Furnaces
Maintenance Tips for Generators and Furnaces are vital for safety and efficiency. Proper care ensures reliable power and heat during outages. Follow these guidelines for peak performance.
