- Additional Appliances: If you plan to power other devices alongside your furnace, add their wattage requirements to your generator capacity calculations. This ensures you select a generator that fits all your power needs.
Selecting the right type and capacity of generator plays a crucial role in keeping your furnace running smoothly during outages.
Running a Furnace on a Generator
Using a generator to run your furnace during a power outage is feasible. Understanding the specifics ensures you maintain a warm home effectively.
Power Requirements
Identify the wattage your furnace requires before connecting it to a generator. Typically, electric furnaces need between 3,000 and 5,000 watts for continuous operation, while gas furnaces generally require between 500 and 1,000 watts. Always check your furnace’s user manual for precise specifications.
Consider both starting and running wattage. Starting watts, which occur when you first turn on your furnace, can be significantly higher than running watts. For example, a furnace may need 3,500 starting watts but only require 1,000 running watts. Your generator must accommodate these differences to function properly.
Additionally, factor in other appliances you may wish to run simultaneously. Calculate the total wattage needed to prevent overloading the generator. For instance, if you plan to power a furnace and a refrigerator, sum their wattages and compare them to your generator’s capacity.
Compatibility Concerns
Not all generators seamlessly integrate with every furnace. Check if your generator type—portable, standby, or inverter—meets your furnace’s needs. Standby generators are usually the best fit since they connect to your home’s electrical system and can handle larger loads effectively.
Inspect the generator’s output. Inverter generators supply cleaner power, which is crucial for sensitive electronics. However, they often have lower wattage capabilities, making them less suitable for high-demand appliances like central furnaces.
Ensure you also have the right connectors and transfer switches to facilitate a correct connection between the generator and your furnace. Professionals generally recommend using a transfer switch to prevent backfeeding, which can damage both your home’s electrical system and the utility workers restoring power.
Monitor your furnace while it runs on a generator. Watch for unusual sounds or performance changes, as these can signal issues. Always refer to both the furnace and generator manuals for specific guidance and any safety precautions.
