Quick Answer
A dual-fuel generator is a suitable choice for home backup power, offering improved efficiency and reduced emissions compared to single-fuel generators, but requires careful consideration of fuel costs and access.
Choosing a Dual-Fuel Generator for Home Backup
When selecting a dual-fuel generator for home backup power, consider the availability of both propane and natural gas in your area. A dual-fuel generator can run on either fuel source, but typically, it’s more efficient to run on natural gas due to its lower operating cost. For example, a typical natural gas generator might cost 12-15 cents per kilowatt-hour to operate, while propane costs around 20-25 cents per kilowatt-hour.
Dual-Fuel Generator Setup and Maintenance
To ensure optimal performance and safety, it’s essential to properly set up and maintain your dual-fuel generator. This includes installing a dedicated propane or natural gas line, as well as a shut-off valve to prevent gas leaks. Regular maintenance tasks, such as oil changes, air filter cleaning, and spark plug replacement, should also be performed according to the manufacturer’s schedule. Additionally, consider investing in a generator transfer switch to safely and efficiently transfer power between your grid and generator.
Dual-Fuel Generator Size and Capacity
When selecting a dual-fuel generator, consider the power requirements of your home. A general rule of thumb is to choose a generator with a capacity of 25-50% more than your total home power needs. For example, if your home requires 5 kW of power during a blackout, consider a 7-10 kW dual-fuel generator. When sizing your generator, also consider factors such as appliance startup requirements and any additional loads, such as lighting or medical equipment.
