Choosing the Right Water Heater

South West Plumbing is proud to provide our customers with the most advanced water heaters available on the market. If you’re not sure which type is right for you, give us a call and we’ll help you make the best choice for your home or business.

Gas Water Heaters

Gas storage tank water heaters use an insulated storage reserve, allowing you to have up to 75 gallons of hot water available on demand. This is a plus for families who use large quantities in a short amount of time. A general rule: the larger your household, the higher capacity you’ll need.

These types of water heaters have gotten much more efficient in recent years, which is important, because water heaters are the second-largest source of energy consumption in the home. In general, the lower the storage capacity, the more efficient the water heater.

The average water heater in our service area has a usable life span of nine to 11 years. Despite newer units having a shorter life span on average, they will you save you more money over time because of lower energy costs.

Electric Water Heaters

Electric water heaters are also very efficient and dependable. They have minimal parts, so there’s often less wear-and-tear for you to worry about. Electric water heaters are a great alternative for people who don’t have access to natural gas.

Today’s electric water heaters can supply enough hot water for the average family, and although the operating cost may be a little higher than natural gas units, they are extremely reliable and typically consume less energy than previous generation models.

Tankless Water Heaters

These days, many of our customers opt for tankless water heaters. They can be gas- or electric-powered and provide an endless supply of hot water, unlike storage tank water heaters, which offer a limited reserve before they need to be replenished.

Tankless units cost more than conventional storage tanks, but their convenience makes them a popular choice. Plus, tankless water heaters are considered a “green” product because they conserve energy, pollute less and require less metal and plastic during manufacturing.

When to Consider Replacing Your Water Heater

•The unit is more than 10 years old
•Rust comes out when using hot water
•You hear rumbling or banging sounds
•You notice water near the unit

How Do I Select the Right Water Heater for My Home or Business?

Your water heater selection can often be narrowed down based on several factors: space, efficiency and capacity.


Are you looking to free-up some storage space in your home or business? A tankless water heater could be right for you, as they’re compact enough to fit underneath your sink. Tankless may also be the right choice if you don’t require hot water in more than one location at a time.


Tankless water heaters are the most efficient because they only consume energy when you use hot water. However, if you have a large home, you may need more than one tankless unit, which is an added expense.


People with large homes or families may want to consider an electric or gas storage tank water heater because of its capacity. Tankless water heaters provide a limited flow of about 3.5 gallons, while storage tanks can provide 75 gallons or more.
