10 The Best Home Generators For Whole House Passed Our Test 2025

Determining the size of the generator needed to power your entire house depends on various factors, including the size of your home, the appliances you wish to power, and your specific energy requirements. To accurately size a generator for your whole house, it's essential to conduct a thorough assessment of your power needs.

Firstly, calculate the total wattage of essential appliances and electronics you want to operate simultaneously during a power outage. This typically includes refrigerators, lights, HVAC systems, sump pumps, and essential electronics. Make sure to consider both starting and running wattages for appliances with motors, as they often require additional power during startup.

Next, consider the peak starting wattage requirements of your largest appliances, such as air conditioners or well pumps, which can significantly impact the size of the generator needed.

Additionally, factor in any future energy needs or expansions you anticipate, such as adding more appliances or rooms to your home.

Once you have a comprehensive list of your power requirements, consult with a qualified electrician or generator specialist to determine the appropriate generator size. They can help you choose a generator with adequate capacity to meet your needs while ensuring efficient operation and longevity.

Remember, investing in a generator that is too small may result in inadequate power during outages, while one that is too large can be inefficient and costly. By carefully assessing your power needs and consulting with experts, you can select the ideal generator size to reliably power your entire house during emergencies, providing peace of mind for you and your family.

Is it worth getting a whole house generator?

Investing in a whole house generator can provide significant benefits and is often worth considering for homeowners looking to ensure uninterrupted power supply during outages. Here are several reasons why a whole house generator can be worth it:

Continuous Power Supply: A whole house generator automatically restores power to your entire home within seconds of a power outage, providing uninterrupted electricity to keep essential appliances, lights, and HVAC systems running smoothly.
Convenience and Comfort: With a whole house generator, you won't have to worry about manually starting and connecting portable generators or prioritizing which appliances to power. Your generator will kick in automatically, maintaining comfort and convenience for you and your family.
Protection of Home Systems: During prolonged outages, essential systems like heating, cooling, and security systems can be at risk. A whole house generator ensures these systems remain operational, protecting your home from temperature extremes and potential security threats.
Preservation of Food and Medication: Keeping refrigerators and freezers powered during outages prevents food spoilage and preserves medications that require refrigeration, saving you money and ensuring access to essential supplies.
Increased Property Value: Installing a whole house generator can enhance the value of your home, making it more attractive to potential buyers, especially in areas prone to severe weather or frequent power outages.
Peace of Mind: Perhaps most importantly, a whole house generator provides peace of mind, knowing that your home and family are protected during emergencies. Whether it's a severe storm, natural disaster, or utility grid failure, you can rest assured that your generator will keep the lights on and essential systems running.
While the initial cost of purchasing and installing a whole house generator may seem significant, the long-term benefits and peace of mind it offers often outweigh the expense. Ultimately, the decision to invest in a whole house generator depends on your specific needs, budget, and priorities. Consulting with a reputable generator specialist can help you assess whether a whole house generator is the right choice for your home.

Is a 22Kw generator big enough for a house?

Whether a 22kW generator is sufficient for your house depends on several factors, including the size of your home, your power requirements, and the specific appliances you want to power during outages.

A 22kW generator is considered a mid-sized to large capacity generator and can typically provide enough power to run most essential appliances and systems in a typical household. This includes refrigerators, lights, HVAC systems, sump pumps, and other essential electronics.

However, if you have a larger home with high power demands or if you want to power additional appliances such as electric water heaters, well pumps, or large central air conditioning units, a 22kW generator may not be sufficient. In such cases, you may need to consider a larger capacity generator to ensure all your power needs are met during outages.

Additionally, it's essential to consider the peak starting wattage requirements of your largest appliances, as they can significantly impact the size of the generator needed. Consulting with a qualified electrician or generator specialist can help you determine the appropriate generator size based on your specific requirements and ensure reliable power supply for your home.
