Buying Guides

1. Types of whole house generator

The first decision when choosing the best whole house generator to make is whether you need a small portable generator or a larger backup generator at home. Due to the best whole house generators consumer reports, there are two types of home generator:

  • Portable generators usually mounted on wheels, must be pushed outside and connected to your home's electrical system when the power goes out. 

  • Standby generators are permanently installed outside your home and automatically start up when there is a power outage in your home.

Each type has its own advantages and disadvantages. Portable generators are smaller and cheaper and they do not require professional installation. However, backup generators are a lot easier to use, making them a better choice for dealing with frequent power outages.

2. Fuel type

  • Gasoline

The most common fuel for portable generators is gasoline. The most significant advantage of this fuel is that it is very easy to buy at any gas station. However, it is not always available in an emergency. 

If a power outage occurs across your entire area, not just your house, gas stations won't be able to use electricity to pump their gas.

  • Propane

You can buy both portable and propane standby generators, which are sold in tanks at major stores. It's not always as easy to buy propane as gasoline because in many places you can't just run down to the nearest gas station to buy it. On the plus side, it's safer to store and lasts almost forever.

  • Nature gas

If you choose a backup generator and your home already uses natural gas for heating, you can simply hook up the generator to your gas line. Although its most significant advantage is convenience, natural gas tends to be cheaper than propane. 

There is no need to purchase and stockpile fuel or refuel the generator when the generator runs out. You have a steady supply flowing through the pipes.

However, natural gas is not an option for a portable generator and it is not practical if you do not have natural gas service at home.

3. Power requirements

You need to look at the size of your house and the appliances you have to determine how much power your generator should have. 

The biggest consumer of energy will be the climate control system (AC or heating), followed by your kitchen appliances. Once you've determined how much total power you need, you can start looking at the right size for the best generator for home.

It's not just the devices you're running. The number of people you live with is important too. As you have more people, your capacity requirements will increase. 

Not only due to increased usage but also because your need for a heat pump or central air also increases. However, a small generator is not necessarily a bad thing.
