2. Selecting The Right Portable Generator

1. Calculating the wattage requirements of your furnace: Determine how much wattage your furnace requires to run properly. This information can usually be found in the furnace’s manual or by contacting the manufacturer. Make sure to account for the starting wattage, as furnaces require a higher amount of power when they first turn on.

2. Consider the generator’s wattage capacity: Choose a portable generator that has a wattage capacity equal to or greater than the wattage requirements of your furnace. It’s important to have enough power to not only start but also run the furnace efficiently.

3. Fuel type and runtime: Decide whether you want a generator that runs on gasoline, propane, or natural gas. Consider the fuel availability and the generator’s runtime, as it should be able to power your furnace for an extended period in case of a prolonged power outage.

4. Noise level: Look for a generator that operates quietly, especially if it will be located near living areas. Some generators are designed to reduce noise levels, making them more suitable for residential use.

5. Portability and size: Choose a portable generator that is lightweight and compact, making it easier to transport and store. Consider the available space and the portability features that will best suit your needs.

By considering these factors, you can select the right portable generator to power your furnace during a power outage or emergency situation.

3. Connecting The Generator To Your Furnace
