What Are Gas Water Heaters?

Most homes have a hot water heater that uses a tank. There are 2 common tank varieties of water heaters – gas-powered and electric. The majority of American households use water heaters with gas burners.

The major difference between a gas heater and electric heater is how the water in the tank is heated. Electric heaters have resistance coils that transfer heat to the water inside the tank. Gas-powered hot water heaters have a gas burner installed underneath the tank to heat up the water.

How Do Gas-Powered Water Heaters Work?

Gas water heaters contain 5 important elements. These are the dip tube, gas burner, exhaust pipe, exhaust vent, and hot water tube. The dip tube is connected to your home’s water line and brings cold water into the bottom of the tank.

When hot water is needed, the gas burner is activated. It heats the cold water that’s sitting at the bottom of the tank. When the water is warm enough, it rises to the top of the tank, near the hot water tube. Water flows through this tube and is routed to all the areas in your house that need hot water, like the kitchen sink, shower head, or washing machine.

The burner is supplied by either natural gas or propane. When it burns, it creates harmful toxins. These are drawn up through the exhaust pipe in the center of the tank. They’re then vented out through the exhaust vent.

The Pros and Cons of a Gas Water Heater

When comparing gas and electric water heaters, gas heaters have a few advantages. Gas water heaters work almost twice as fast as electric to heat water and still work if there’s a power outage (since they’re not powered by electricity). They might also be cheaper if natural gas is less expensive than electricity in your area.

There are some drawbacks to gas-powered heaters, however. Your home needs a gas line to install one, and putting in a new gas line is expensive. Gas heaters are also more costly than electric upfront, and you likely won’t see savings on your energy bill for a while. Gas water heaters don’t last as long as electric and since they require a ventilation system for the burner’s exhaust fumes, they are harder to install.

Tankless water heaters are becoming a popular alternative to traditional hot water tanks. They offer several advantages over tanks, but they’re not without their downsides either. In this guide, we will give you a crash course in tankless water heaters, how they work, and the pros and cons of buying one.

What Is a Tankless Water Heater?

A tankless water heater is able to provide hot water without having to store it in a large tank. Typically, cold water is piped through an electrical or gas-powered heater before going to the point of use. This setup eliminates the need for a large tank of full of hot water ready to use. But the flow of hot water might be more limited with a tankless heater than with a tank.

Tankless water heaters are able to serve either one point of use or an entire house. When they’re installed in a house, usually several units are required. Tankless heaters are great if you want to heat a single point, like a bathroom, in addition to a regular water heater.

Tankless heaters typically last about 20 years. They’re also able to deliver hot water at about 2-5 gallons per minute. Gas-powered tankless water heaters tend to produce hot water faster than electrical heaters.

What Are the Pros and Cons of Tankless Water Heaters?

If you’re considering switching to a tankless water heater, it’s important to evaluate their advantages and disadvantages.


Tankless heaters are more compact. They usually hang on the wall, taking up significantly less space than a traditional water heater. They also waste less water and are more energy-efficient. With a tankless water heater, water is only heated and delivered when it’s needed rather than sitting in a tank.

Tankless heaters are also safer than traditional tanks. With tanks, there’s always the risk that they’ll leak or harbor bacteria. They also last up to 20 years, whereas a tank must be replaced every 5-6 years.


Tankless water heaters are more expensive. They will eventually save you on energy costs, but these savings won’t come until about the sixth year you’ve owned it, considering how much they are upfront.

Tankless heaters can also fluctuate the water flow in your home depending on pressure; they also can’t handle hot water for simultaneous uses.

How Do You Install or Repair a Tankless Water Heater?

If you want to install a tankless water heater that uses gas, you and your plumber will have to inspect the gas line beforehand. The tankless heater must be hooked up to a gas supply line to work. If the unit doesn’t have its own cooler exhaust, then it must be vented as well. It’s also worth considering investing in water treatment if you have a problem with water hardness. A buildup of hard water deposits can cause a slower heating time.

When it comes to tankless water heater repair, you can do some troubleshooting yourself. If there’s no hot water, for example, check the water and power supply to make sure both are turned on. If the water is too hot or not hot enough, reset the unit temperature to 120 to 125 F. You should also clean the filters and filter aerators.

For tankless water heater replacement, consider calling a professional service to do the job for you. A qualified technician will know how to handle replacement and prevent costly mistakes.
