In an age where reliable power is crucial for daily life, whole house generators offer an indispensable solution for homeowners. Among these, 22kW generators stand out as ideal for providing sufficient power to keep an entire home operational during outages. These generators can support essential appliances, heating and cooling systems, and even larger electrical demands, ensuring your family remains comfortable and safe during unexpected power disruptions. This article will explore the 7 best 22kW whole house generators available in the market, evaluating their features, performance, and reliability. By the end, you’ll have a comprehensive understanding of which generator might be the best fit for your needs.
What is a 22kW Whole House Generator?
A 22kW whole house generator is a type of standby generator designed to provide backup power to an entire home during power outages. It is typically permanently installed outside the house and automatically engages during an outage. With a power output of 22,000 watts, these generators can handle a significant electrical load, making them suitable for larger homes with multiple high-demand appliances.
How Do 22kW Whole House Generators Work?
When a power outage occurs, a 22kW generator automatically detects the loss of electricity through a transfer switch connected to your home’s electrical panel. Within seconds, the generator starts and begins supplying power to the home. Most models run on either natural gas or propane, providing a consistent and efficient power source.
The automatic transfer switch not only helps in switching power sources but also ensures that the generator operates safely. It isolates the generator from the grid, preventing back-feeding electricity that could endanger utility workers trying to restore power.
