Buying Guide For Whole House Gas Generators
Choosing the best whole house gas generator involves considering several important factors to meet your home’s backup power needs:
1. Power Output (Wattage)
Assess the total wattage required to power your essential appliances and systems during an outage. Whole house generators typically offer from 10,000 watts to over 28,000 watts. Larger homes or homes with heavy electrical loads need higher wattage capacity.
2. Fuel Type
Generators often run on gasoline, propane, natural gas, or a combination (tri-fuel or dual-fuel). Tri-fuel provides the most flexibility, allowing you to switch between gas types depending on availability and price.
3. Starting Method
Electric start options including remote starts add convenience, especially during emergencies. Automatic start generators turn on immediately when power is lost without user input, ideal for home standby use.
4. Transfer Switch Compatibility
Whole house generators usually require a transfer switch to safely isolate generator power from the utility grid. Ensure the generator you choose is compatible or comes with a transfer switch, simplifying installation.
5. Run Time and Fuel Tank Size
Longer run times reduce the need for frequent refueling during extended outages. Larger fuel tanks support longer operation but add weight and size to the unit.
6. Noise Level
Generators vary in noise output measured in decibels (dBA). For residential use, quieter units below 70 dBA help reduce disturbance in neighborhoods.
7. Durability and Warranty
Consider generators with robust engine construction like cast iron sleeves and protective enclosures that withstand outdoor conditions. A comprehensive warranty provides peace of mind.
8. Additional Features
- Remote monitoring and WiFi connectivity for ease of use
- Multiple power outlets for versatile connections
- Automatic low oil shutdown and CO safety mechanisms
- Digital displays to monitor output and runtime
