Best Whole House Generator

Whole house generators are becoming increasingly popular worldwide, but in particular, they have grown in popularity here in the USA.

In some States where power outages are commonplace, and the stormy weather constantly threatens the electricity supply to your home, a backup power supply is an absolute must.

This is why a backup generator is so good because in the event of a power outage all of the critical home appliances in your home will continue to receive power.

So you no longer have to worry about your freezer defrosting and the food going to waste, or having to light candles the next time your power goes out. 

But the generator market is an incredibly saturated sector. There seem to be generators designed for just about anything nowadays. From portable generators for camping trips to generators to power your outdoor lighting to generators which can power your entire home.

The opportunities for a generator seem endless, so, understandably, you might become confused when you go on the search for the perfect generator for you.

Dual-fuel capability is great because it gives you a lot more freedom, and allows you to use propane if you cannot get gasoline and vice versa. 

This device is also very versatile in how you can activate the device. Many generators will require a manual pull start to activate the device which might not be convenient in a lot of circumstances.

If you don’t want to have to go to the generator to manually start the device, this generator comes in handy as it comes with a remote start key fob which allows you to start the device without being close to the device.

We also love the Pulsar G12KBN heavy duty portable generator. This device is very similar to the Westinghouse generator as it matches its power output.

Similarly, this product by Pulsar also comes with dual fuel capability for excellent convenience and can provide continuous power for 12 hours.

The G12KBN model also has a low oil shut off feature which prevents damage to the fire and reduces the risk of fire. 

However, it differs from the Westinghouse model as it comes with a 3-in-1 digital meter that is displayed on the face of the product.

This digital device allows you to continually monitor the operation of your generator, this will allow you to easily identify when the generator needs refueling and monitor the performance of your generator.

This device performs slightly less powerfully than the models that have come before it, with a continuous power of 9,500 Watts and a peak of 12,000 Watts.

However, similarly to both the Westinghouse and Pulsar models, it has dual fuel capability and is compatible with both gasoline and propane. 

Additionally, this device comes with the low oil shutoff feature which is an essential thing to look for if you have safety in mind.

However, this device goes a step further as it comes with an idle control feature.

This feature not only provides added safety to the device but is also a lot more cost-effective as it will ensure no fuel is lost when the device is not being used, making it both cost-effective and a more environmentally friendly option.

With everything in mind, it’s clear that this is a great option if you are looking for a whole house generator.

For a device as big and powerful as this you would expect it to have loud operating noise, but this device is one of the quieter options on the market with an operating noise of 76dB.

Best Whole House Generator Buying Guide

Generators are a great investment simply because they have so much potential. They come in a variety of shapes and sizes which are all better suited to different situations.

You can get smaller, portable generators that are perfect for camping trips or family barbeques, and you can also get huge generators that supply enough electricity to power your entire home.

Whole house generators are a trend that is continually growing more popular as an increasing amount of people are choosing to install them in their own homes.

Whether you choose to use the generator as a continual source of power for your home, or simply as a backup in case of emergency, there are all sorts of benefits from a whole house generator.

But with so many different types of generators available it can be very difficult to determine which is the best one for you and your home. There’s no need to stress, however, because we’ve put together this great guide which is packed full of information about whole house generators.

The generators that we’ve looked at above are some of the best on the market, but if you’re still not sure, this buyer’s guide is packed full of all the information you need to buy the whole house generator which is perfect for you. 

Fuel Source

One very important thing that you need to consider when buying a whole house generator is how you are going to power the device.

This is especially important if you live in an extremely remote area of the country as it can be very difficult to get your hands on the fossil fuels that you need to power the generator.

Most whole house generators will come with three different fuel options for you to choose from, these include natural gasoline or diesel, or propane. 

Both gasoline and diesel are the traditional options we would consider when considering powering a device. The majority of vehicles are powered by gasoline or diesel, that’s because both of these materials are extremely easy to obtain.

However, it might become more difficult to obtain these fuels when you consider the amount that you will require to power the whole house generator. All whole house generators will come with an extremely large fuel tank and will require this tank to be full for them to operate properly.

Before you buy a home generator, you must consider the fuel source to ensure you buy one that you will be able to access easily. You should also consider the cost of different fuels.

Obviously, fuel prices fluctuate dramatically from day to day, however, on average, some fuel sources are more expensive than others so you should consider which is a better financial choice for you and your home. 


Another extremely important thing that you need to consider is the power that you require from the generator. Different generators will come with different power output abilities which will limit or expand the number of appliances that the generator can supply power to.

In order to power the majority of household appliances, you will need a generator that can produce between 5,000 and 7,000 watts of electricity. However, to operate all of these devices simultaneously, you should buy a generator which exceeds these measurements. 

To ensure that you buy a generator that is powerful enough to provide electricity to all of your household, you need to calculate how much electricity all of your household appliances will require.

To do this you need to look at each of your electrical appliances and find the plate which states their starting amps. Once you have found the starting amperage, you also need to identify the volts for the device, you should then multiply these with one another and this will determine the watts that the device needs to run.

You should do this for all of the items in your household that you want to be powered by the generator to determine how powerful a generator you need to buy.

However, when buying a generator you should purchase one that has a peak load which is approximately 25% more powerful than what you need. This is essential to ensure that the generator always has enough power to supply electricity to your whole home.
