But the real question is…

Is It Worth it?

While you might consider buying a smaller generator to support only the essential devices during a power failure, you must give whole house generators a good chance…

Because these generators will fulfill your pipedream of an unhinged household

However, there are a few things you might have missed while window-shopping for generators, and we will point them out for you. 

Here are a few reasons why you must consider buying whole house generators:

1. Your Work-Life Needs You

The coronavirus outbreak has caused numerous employees to work from the comfort of their homes. While working from home has its benefits, interruptions due to blackouts and lack of electrical energy are not one of them. 

This results in a severe lack of productivity and failure to meet deadlines.

2. It Will Save Your Loved One’s Life

If you have a family member plugged into a life support system, you need to consider buying a whole house generator without a second doubt. Furthermore, home healthcare devices may be required for monitoring in-house patients’ health.

However, you can sigh in relief during a calamity with a large backup energy source. 

3. Keep Your Family Safe

Whole house generators will help keep your family safe from tsunamis and flooding by running the sump pumps efficiently.


A sump pump is an electronic device that aids you during floods. It removes the water gathered in your homes (basements) during a flood and pumps it to a safer area. 

This prevents water surges in your homes and a secure experience during natural disasters. 

However, without a power supply, sump pumps do not work. Therefore, you need a generator that can sustain the electrical weight of sump pumps alongside the household appliances.

What To Look For In a Whole House Generator?

Buying the perfect whole house generator requires a lot more than its benefits and losses. You need to know what features and qualities to look for before purchasing:

The Right Fuel Type

A generator runs on different energy fuels, each with its perks. Making the right decision means you need to consider the maintenance, cost, and several other factors. It is also necessary to accommodate your needs and your lifestyle. 

Whole house generators run mainly on three types of fuel:


Gasoline is the poorest fit for portable generators, and it has a short shelf life and is volatile, so storage is hazardous. Any small flame can result in an explosion if you are not careful.

Furthermore, gasoline is the poorest option of the three due to its deteriorating quality.

Natural Gas or Liquid Propane Gas

Natural calamities fail to severely affect gas supplies, making natural gas an efficient fuel source during emergencies. Moreover, natural gas is more eco-friendly than gasoline and diesel, and it burns cleaner in the generator with no harmful byproducts.

Natural gas is a reliable source of energy that allows efficient combustion without any errors. It also has an extended shelf life.


Diesel generators are efficient and tend to be very reliable. It is a low volatile, high-energy, and stable fuel that has a low consumption rate, allowing cheaper maintenance in the long run.

However, diesel requires large tank storage, which can be a hassle for properties without a proper storage room.

What Capacity Works For You?

The amount of power your generator can provide is often called its capacity and is measured in watts. You must consider how much electrical weight your generator needs to support before buying a whole house generator.

While a generator has a wide capacity range, a whole house generator usually lies above 20000 watts

22000W – No Room For Desires

This generator can support a good amount of house appliances, and it can easily cover all the necessary devices, especially for a large family.

Plus, it is a go-to for small house owners looking for survival during difficult times rather than comfort. 

35000W- Convenience On A Leash

A 35kW house generator allows almost all of your house to run smoothly, supporting all heavy appliances, with slight changes after the power switch. You can easily connect your portable devices for extensive usage using a capacity as large as this.

However, you cannot overload the generator by abusing its abilities, as it may result in a spark or fire.

50000W- Unbothered Queens

These are the biggest, most durable whole house generators, and it supports your entire living abodes without a bother…

The switch is unnoticeable, and the load is almost unending. The 50kW generators are ideal for individuals with a big wallet and a need for endless comfort.

It can take up the weight of all devices in your house. It’s like the light never went out!

Get Rid Of Overload Problems

An electrical overheating incident in a generator can result in unfathomable dangers. This is why it’s advised to regularly turn off the device to cool down before restarting it for extended usage. 

Nonetheless, doing so amidst unforeseen circumstances manually, outside the safety of your house, is too risky. Hence, an automatic shut-off is installed in whole house generators.

This allows automated detection of overuse and cut-off power for a short period. Generators last longer and run efficiently due to this technique.

Automatic Connection Established

An automatic transfer switch is a button-like device for your generator that turns it on when required.

During a blackout, the transfer switch will take notice of the absence of electrical supply from the primary power source and immediately put the generator to work. 

ATS allows a safe transfer of the energy supply to the power grid without any damages and manual labor. It is installed by an electrician while connecting the generator to the house.

What Are Home Standby Generators?

Home Standby generators act as secondary power sources to larger properties in a neighborhood. Home standbys are often confused with whole house generators due to the lack of portability and permanent embodiment.

We thought to clear the confusion out!

While the two devices may seem similar, it is essential to know that home standby generators are used as survival power sources. These generators are used only for critical devices during a blackout and are smaller in capacities. 

They cannot support entire homes with extra appliances, unlike whole house generators.

Installation – You Are Not Good Enough!

A generator installation is not child’s play. Heavyset, permanent generators are more challenging than most and require expert’s knowledge to be handled accurately.

Do not put yourself up for a challenge to install the whole house generator by yourself. Even with all the help with online manuals, blogs, and videos, you will fall short of the experience by a lot.  

It is best to hire a professional to do the job for you, as it would be safer that way. The cost of an expert may be high, but some things are worth the money. 

The Question Remains: Is It Worth It?

Whole house generators are pricey investments into your lives that will affect each individual differently. The bottom line is that while the benefits were flattering, the cost fixed you right up. 

A family of three and more has several other expenses that need to be covered before worrying about the blackout occurring every two months. There are viable options better suited for you then, and however, with the availability of funds, it is a feasible choice.

Convenience Is Worth Every Spare Penny!

Consider all the points mentioned above before spending ten grand on a generator. It will not be the same for everyone. Plus, consider other factors that suit your lifestyle and environment.

So that you finally come to a bright conclusion:

It Is Worth It… For You!
