Continuous electricity is easy to take for granted but just think of what happens when your power goes off. You're on Christmas vacation, for example, and an ice storm downs power lines in your area. In the winter, your forced-air furnace also stops because it relies on electricity to power the fan. At home, you're huddling under blankets and worrying about the pipes bursting. Not to mention the sump pump dying, too, and water backing up in your basement.
Power outages are no problem with an automatic whole-house generator.
Just hear that reassuring hum within a matter of seconds after the power goes off. Sitting near the foundation, it's as quiet and unobtrusive as a central air conditioner unit. The right generator will provide enough power for the entire home if you calculate your electricity needs. You'll need to add up the total wattage for all essential appliances that must stay on during a power emergency. 8 to 12 kilowatts should be sufficient.
