What Are Natural Gas Backup Generators?

Natural gas backup generators for homes are permanent installations that automatically kick in when your main power supply fails. They’re connected to your home’s natural gas line, meaning you never have to worry about refueling or running out of fuel in an emergency.

Unlike portable gas or diesel units, these generators are made to support your home’s most essential systems long-term. That includes your heating and cooling systems, medical devices, and refrigerated food storage.

Top Benefits of Natural Gas Backup Generators for Homes

  1. Reliable Fuel Source
    Natural gas pipelines are rarely impacted by weather, meaning your generator is always ready.

  2. No Refueling Required
    Unlike diesel or propane generators, natural gas backup generators for homes draw fuel automatically.

  3. Environmentally Friendly
    Natural gas burns cleaner than diesel, releasing fewer emissions into the air.

  4. Cost-Effective Over Time
    While the initial installation may be higher, the fuel costs are typically lower than propane or gasoline alternatives.

  5. Increased Property Value
    Homes with natural gas backup generators are more appealing to buyers, especially in areas with frequent outages.

Installation Considerations

Before installing, consider:

  • Generator size: Whole-home or essential circuits only?
  • Location: Local codes require a certain clearance from windows and doors.
  • Permits: You may need electrical and gas permits depending on your municipality.
  • Professional installation: Always work with licensed technicians to ensure safety and compliance.

Cold Weather Performance

British Columbia’s winters can be harsh. Fortunately, natural gas backup generators for homes are designed to work reliably in cold temperatures. Unlike diesel, natural gas doesn’t gel in freezing weather, and with a cold-weather kit installed, your system can start instantly even on frosty mornings.

Noise & Maintenance Expectations

Modern natural gas backup generators for homes are designed with noise-reducing enclosures. Expect a hum, not a roar. Routine maintenance involves oil changes, filter replacements, and periodic load testing — all of which can be scheduled annually through Whyte’s service packages.

Frequently Asked Questions

How long can a natural gas generator run?
Indefinitely, as long as the natural gas supply is uninterrupted. Most homes can operate for days without issue.

Can it power my entire home?
Yes, with the right sizing. Our team can calculate what size you need based on your circuits and energy usage.

Do natural gas generators work during earthquakes?
In BC, gas lines are typically buried, protecting them from wind and snowstorms. However, a major seismic event could disrupt supply.
