Three Key And Important Differences Between Installing A Gas Water Heater And An Electric Water Heater

Posted on: 3 December 2018

If you have not checked on your water heater recently, you may want to check it now. Go on; this will still be here when you get back. Okay, now that you have checked on it, what kind is it? Do you have a gas water heater or an electric one? Oh, you need to replace it because it is not working? Well, then, all the more reason to know which type you have. You should know, because there are some key and important differences that will affect installation with the new water heater. 

​Gas Line Installation Has Extra Steps

Considering the amount of water you probably use in a month, you are more likely to have a gas water heater. That is the most common type because you can use the city's gas lines to provide fuel directly to the water heater. If you have gas heat, then the chances of having a gas water heater are even higher because of the convenience factor. 

When installing the new water heater to replace your old one, the gas has to be turned off via a valve. This also turns off the gas to the rest of the house, for safety reasons. Then the gas line is disconnected from the old water heater, the old water heater is dragged up the steps and/or out of the house, and then the new water heater is unboxed and positioned for reconnection. Some welding is required to attach the new water heater to the gas line before the gas line valve can be opened up again.

​Electrical Installation Is Faster and Easier

That is vastly different from the electrical water heater installation, which only requires a disconnect and reconnect to the electrical wiring that runs from the fuse box or electrical box to the water heater. An electrical water heater, therefore, is less dangerous and requires fewer steps to install. The whole process goes much faster than it does with a gas water heater.

Plumbing Connections Are Different Too

With gas water heaters, the water is often distributed into the appliance in a port at the top. Pipelines run above the appliance and come down to meet the top of the appliance. In electrical water heaters, the port of entry for water can be in the side or even in the bottom of the appliance to avoid getting water too close to electrical wiring and components.


Knowing When It’s Time to Call the Plumber

My name is Jason Lawrence, or around my house I’m sometimes known as “Daddy Fix-It.” My wife Sarah and I have four children all under the age of ten. I didn’t start out as a guy who was handy around the house, but I am learning to become a do-it-yourselfer for sure. Did I mention that I’m a bit stubborn? There are times I struggle with projects a little too long, and it takes my wife stepping in to convince me that it’s time to call a professional. I’ve become especially handy with plumbing projects. I don’t know why kids think toys belong in the toilet and doll hair is good for the bathtub drain, but around here those are weekly events. I’m going to share some of my experiences, how I fixed some of our plumbing problems, and when it becomes time to call the plumber.
