Buying Guide for Whole House Generators
Choosing the right whole house generator involves balancing power output, fuel type, and operational features based on your home’s size and energy needs.
Power Capacity
Assess your home’s electrical load, factoring in critical appliances like HVAC, refrigerators, and lighting. Generators range from around 10,000 watts for smaller homes to over 22,000 watts for larger properties.
Fuel Type and Efficiency
- Gasoline: Common and easy to refill but less efficient for long-term emergencies.
- Propane: Cleaner burning with longer shelf life and is often available as dual fuel.
- Natural Gas: Steady supply if connected to utility lines, ideal for standby units.
Installation and Transfer Switch
Many whole house generators include or require a transfer switch with ratings typically at 200 Amps for whole house coverage. Installation complexity affects upfront costs—models reducing wiring hassle might save money and time.
Features for Convenience and Safety
- Remote Monitoring: WiFi-enabled models allow status updates and maintenance alerts on the go.
- Electric Start: Enables easier startup, particularly for portable units.
- CO Alerts: Carbon monoxide detection enhances safety around living spaces.
- Noise Level: Lower decibel generators improve residential neighborhood comfort.
Durability and Warranty
Search for models with rugged construction such as aluminum enclosures and long warranties (e.g., 5 years) to protect your investment over time.
Portability Versus Permanence
Portable generators are flexible for RVs or multiple locations but might lack the automatic features of standby units. Standby generators automatically engage during outages and often provide whole house coverage more seamlessly.
