Is This Generator Right for You? The Champion 22kW is ideal for homeowners with 2,000+ square foot homes who want automatic, hands-free backup power. It works best if you have natural gas or propane available at your home and can accommodate professional installation by a licensed electrician.

Installation Considerations: Professional installation is required and typically costs $1,500 to $3,500 depending on your home's electrical setup and distance from the meter. The fleX technology actually reduces installation complexity compared to traditional generators, potentially lowering labor costs. Ensure your installer is familiar with Champion fleX systems for optimal setup.

Fuel Source Selection: Choose propane if you want maximum power output and efficiency. Natural gas is convenient if already available at your home but provides slightly lower output. Many homeowners maintain a propane tank as backup for extended natural gas outages.

Load Management: This unit handles most household loads automatically. For homes with multiple high-demand appliances (central AC, electric water heater, pool pump), consider the optional fleX Load Management Module to prioritize essential loads and prevent overloading.

Maintenance: Dual fuel generators require minimal maintenance. Annual servicing and fuel stabilization are recommended. The 10-year warranty provides excellent long-term protection, and Champion's lifetime technical support ensures you have expert help when needed.
