What Is a Whole-House Generator?
A whole-house generator, also known as a standby generator, is permanently installed to provide backup power during outages. It is connected to your home’s electrical panel and uses an automatic transfer switch to detect outages and switch power from the grid to the generator. A whole-house generator typically runs on either natural gas or propane and less often diesel.
Benefits of a Whole-House Generator
Why invest in a whole-house generator? The benefits of a whole-house generator are many. Beyond the obvious benefit of restoring power during an outage, whole-house generators:
- Keep heating and cooling running: During a power outage, HVAC systems stop operating. With a whole-house generator, you can maintain you heating and cooling, providing comfortable and safe living conditions.
- Protect plumbing from frozen pipes: Winter storms pose the risk of frozen pipes during outages. By keeping your heating system running, you protect your plumbing from frozen pipes.
- Keep refrigerators and freezers powered: Avoid food waste by keeping your refrigerators and freezers running during power outages. A generator ensures you have safe food to eat in the fridge and freezer during an emergency.
- Support medical equipment and home offices: A whole-house generator is essential for those with lifesaving medical equipment or home offices. A generator keeps medical equipment operable and minimizes downtime for people working from home.
- Provide safety and security during storms: A whole-house generator also allows for safety and security systems to be used during times of emergency. Protect your family and property by maintaining security systems even during storms.
When Do You Need a Whole-House Generator?
Wondering if a whole-house generator is worth it for you and your family? There are a handful of reasons to get a whole-house generator installed, including:
- Frequent outages in Kentucky due to storms and ice: If you live in an area that sees frequent power outages, you may consider a whole-house generator. Kentucky’s storms and ice can cause loss of power for extended periods.
- Homes with children, seniors, or medical needs: Families with young children, seniors, or important medical devices should prioritize keeping electricity on for household members’ safety and well-being.
- Properties with sump pumps or well pumps: If you own a property with a sump pump or well pump, ensure continuous water supply and prevent basement flooding with a whole-house generator.
- Households running home offices or relying on continuous internet: Work-from-home business owners who rely on continuous internet can benefit from a whole-house generator. Minimize costly downtime with continuous power.
Fuel Source Options
There are several fuel source options for whole-house generators, including natural gas, propane, and diesel.
- Natural gas is the most popular option for whole-house generators because it offers unlimited supply if utility-connected. Whole-house generators can be connected to natural gas to provide an automatic and steady fuel source. This allows the generator to run indefinitely in times of emergency.
- Propane is another option for whole-house generators but is more popular with portable units. You must consider the tank size and how long the generator can run before refueling is required.
- Diesel is the third option but is less common for residential settings. This may require hiring a company to deliver diesel to refuel your generator, but nevertheless, it is an option.
Installation Process & Professional Support
The installation process for whole-house generators includes site assessment and sizing, permit and code compliance, and connection to an electrical panel with an automatic transfer switch.
First, a professional electrician will assess your home site and its power needs to recommend the proper size whole-house generator. They will let you know what wattage you should look for when purchasing a generator.
Once you have the whole-house generator, an electrician will work to install it properly, following local permits and codes. The generator will be permanently installed outside your home and connected to the electrical panel with an automatic transfer switch.
It’s critical to work with a licensed professional for generator installation. Professional electricians, like those at Dauenhauer, will ensure proper installation for safe operation.
