The Best Whole House Generators for All Your Energy Needs

Home is where the heart is. When you’re ready to spend more money on a home, you want something that will last you a lifetime  not something that costs an arm and a leg to install.

A whole house generator is one of the best ways to go about getting the most out of your electric system.
Working with electricity has been around for hundreds of years, so it shouldn’t be any surprise that people have been creating energy efficient devices for centuries.

The electrical industry has long been focused on efficiency, with devices like solar mirrors and photovoltaic panels being among the most efficient designs available. But even though these technologies have become common, they aren’t universal. That’s because most homes don’t have windows or doors, which makes it difficult to find efficient ways to power entire rooms from renewable energy resources such as solar or battery storage systems. Thankfully, there are plenty of other options and some that are cheaper than installing a new generator!

We’ll review the best whole house generators you can buy and why you should consider buying without a warrantee (rather than buying second-hand), as well as what conditions qualify you for one instead of another.

What is a whole house generator?

A whole house generator is appliance that produce its own electricity. You can’t just plug in a light bulb and get the power it produces. A whole house generator uses a combination of energy-efficient appliances to produce its own electricity. These appliances vary in price and complexity, so start by looking at the total cost of installing and keeping one to see if it’s the right choice for your money.


Buying Guides

What’s the difference between a whole house generator and an energy storage system?

The main difference between a whole house generator and an energy storage system is the type of electricity produced. In general, an energy storage system stores electricity in a variety of devices — usually giant lithium-ion batteries, which are great for storing energy in the event of a power outage like a fire or lightning strike. But a whole house generator uses an inverter to convert the electrical energy stored in the batteries into useful energy. An inverter can be cheaper, smaller, and produce energy more commonly needed in other forms — like power to run appliances or provide power to equipment like a water heater or fire Hydrangea Smart Water Heater: The ideal water heater for small homes, with a large footprint and no backyard.

How to buy a whole house Generator

You can buy a whole house generator at large home improvement stores for under $1000. The prices can reflect this at least a little, but the main difference here is the amount of electricity you’re buying. You might have one or two lights on — not a lot, but a few to light your path. You could buy a 50,000-lb. house and get into the $300,000 range. Or you could go with a $5,000 house and use the generator to run lights and appliances, paying the return cost of the generator at the end of the month.

Why you’ll want a whole house generator

Because electricity is a must-have in our daily lives, it’s easy to forget about all the good things you can do with it. That’s where a whole house generator — which doesn’t use electricity at all but instead creates electricity from humble resources like wind or solar — can make a big difference. You won’t use as much electricity because these appliances won’t be producing as much electricity.


Bottom line

If you’re ready to make big changes in your home and want to get the most out of your energy budget, you should consider buying a best whole house generators. Home is where the heart is. When you’re ready to spend more money on a home, you want something that will last you a lifetime not something that costs an arm and a leg to install. A whole house generator is one of the best ways to go about getting the most out of your electric system. Regularly use these appliances to keep your home energy efficient. They’ll only become more efficient as you use them more. By consistently using these appliances, you can expect to see your energy use drop by up to 30 percent.
