Wondering how much fuel your backup generator consumes? Vaccarella Electrical Services breaks down natural gas usage for whole-house generators in Bergen County, NJ.
Quick Answer: Natural Gas Consumption
A typical whole-house generator in Northern New Jersey consumes between 1.5 to 3.5 cubic feet of natural gas per kilowatt of power output per hour, depending on the load. For an average 20kW standby unit, you can expect to use approximately 150 to 250 cubic feet per hour under a full electrical load.
Understanding Generator Fuel Efficiency
When considering a standby generator installation in Bergen County, NJ, understanding fuel consumption is vital for long-term planning. Unlike portable units that run on gasoline, whole-house generators connected to your home’s natural gas line provide a continuous, reliable fuel supply. Efficiency is primarily dictated by the total wattage being demanded by your home at any given time.
How Load Affects Natural Gas Usage
Your generator only uses the fuel it needs to meet the current electrical demand of your home. If you are running only essential circuits during a power outage in Paramus or Ridgewood, your engine will run at a lower RPM and consume significantly less natural gas than if your entire HVAC system, appliances, and lighting are active simultaneously.
Generac vs. Kohler: Fuel Consumption Comparison
Both Generac and Kohler generators are engineered for high efficiency, though specific consumption rates vary by model size. The following table provides a general estimate for natural gas usage based on common unit sizes.
| Generator Size | Approx. Fuel Consumption (Full Load) |
|---|---|
| 14kW | 140-160 CFH |
| 20kW | 200-240 CFH |
| 24kW | 250-300 CFH |
The Role of the Transfer Switch
A professional generator installation by a licensed contractor like Vaccarella Electrical Services involves installing an Automatic Transfer Switch (ATS). This device senses utility power loss and triggers the generator. Because the ATS manages the flow of power, it ensures your generator only draws the necessary amount of gas to support the circuits you have prioritized, preventing unnecessary fuel waste.
Northern New Jersey Utility Considerations
In Bergen County areas such as Franklin Lakes, Fairlawn, and Hackensack, your home’s natural gas pressure is key. We ensure that your gas meter and piping are sized correctly to supply the required Cubic Feet per Hour (CFH) to the unit. Inadequate piping can lead to performance issues or engine failure during a storm.
Maintenance and Long-Term Efficiency
Regular service is essential to ensure your generator runs as efficiently as possible. A well-maintained engine burns fuel more cleanly and effectively, ensuring you get the most out of every cubic foot of natural gas. If you are in Mahwah, Englewood, or Teaneck, call us to schedule your annual maintenance check.
Other Questions People Ask
Is natural gas cheaper than propane for generators? Generally, yes. Natural gas is typically more cost-effective as it is piped directly into your home without the need for tank refills.
Can my gas meter handle a generator? Many older meters require an upgrade to handle the increased load of a standby generator; we assess this during our consultation.
Does a generator run constantly? No, it only runs when utility power fails or during scheduled exercise cycles.
What is an exercise cycle? It is a short, weekly self-test that keeps the engine lubricated and ensures the system is ready for emergencies.
