Power Outages Can Drain Your Funds

National averages show that a power outage can drain more than power, it can actually drain your pocketbook! Think about it. If you lose power and have to stay at a decent hotel, that can cost you more than $150 a night not to mention the hassle of having to leave your home.

On top of that think of the amount of money you can lose in spoiled food! Statistics show that this can be well over $200.

Then there is the possibility that a power outage can leave your basement flooded with the lose of power to your sump pump. With the cleaning, having to refinish the floor, possible damage to your furnace, and possibly fixing the walls, this can run over $20,000 in some cases.

We didn’t if figure in the cost of mold removal should this occur later on down the road. This can cost over $3,000.

There will always be threats that can cause you to lose power. You can accept the hassle and the risk of possible power outages, or you can make a small investment into a home standby generator.

What you can gain from this definitely outweighs what you have to lose.

What Is A Standby Generator?

There are two types of generators, a portable generator, and a home standby generator. The main difference between a portable generator and a home standby generator is that standby generators are permanently wired into your home and are engineered to turn on automatically as soon as the power goes out.

There is nothing you have to do and even if you’re not at home when the power goes out, a standby generator will still come on.

Portable Units Can Be A Pain

In contrast, although super handy and versatile, portable units can truly be a pain because you must connect them to your house with a cable.

This can be an extension cord so you can plugin many individual items or you can connect through a switching device to your panel.

Power Output

Another major difference between portable and standby generators is that the power output from a portable generator is very small compared to that of a standby generator, which means you can only power a few items in your home.

Standby generators are larger and can produce power to provide electricity to every part of your home.

One of the biggest benefits for some is that you do not need to add fuel with a standby generator. This can save money and hassle.

Standby generators are typically permanently connected to a supply of natural gas or propane, and these fuels automatically flow to the generator without any work on your part.
