The Right Time to Replace Your Water Heater in the Greater Phoenix Area

Traditional water heaters have a general life expectancy of about 8 to 12 years. When your unit is becoming more costly to operate or can no longer keep up with demand, it may be time for a replacement.

Other signs that indicate it’s time for a new water heater include:

  • Water leaks: Do you see any water pooling around your unit? This could be a sign of corrosion, which is common in older tanks.
  • Poor water quality: Cloudy, rusty water coming from your taps could mean that your tank is rusting on the inside.
  • Visible damage: If you can see any cracks or dents in your tank, contact us immediately.
  • Frequent breakdowns: Are you calling for repairs more often than you used to? This could signal that your system is nearing the end of its life.

If you’re not sure whether it’s time for a replacement or just repairs, don’t hesitate to call our professional and transparent technicians for assistance. As a family-owned and operated business, your satisfaction is our number one priority, and we’re happy to advise you on the best option for your home.

How Do Tankless Water Heaters Work?

While traditional systems heat and store water in a holding tank until you need it, tankless units heat water on demand.

When you turn on a fixture, cold water runs through a pipe and into the water heater. A heating component then warms the water as it passes through and finally reaches the fixture via another pipe. This process immediately ends when you turn off the heater to limit energy waste.

Tankless water heaters are available in electric and gas models, but the latter is much more common. That’s because they can provide a higher flow of hot water than electric models.

Why Should You Go Tankless?

There’s a reason why tankless water heaters have increased in popularity over the past few years. Here why:

Space Savings

The most obvious benefit of a tankless water heater is its smaller size. Without a tank for storing hot water, we can install these appliances virtually anywhere on your property—even outside! This is an excellent option for those who want to reclaim valuable storage space inside their homes or businesses.


Another compelling reason to choose a tankless water heater is safety. There’s no tank of hot water sitting around, which significantly reduces the risk of scalding and leaks.

Tankless water heaters also come with many features that make them safer to use, such as:

  • Automatic shut-off valves that turn the unit off if it overheats
  • Child locks that prevent accidental burns
  • Flame safeguard controls that monitor the burner and shut it off when there’s a problem
  • and more!

Life Cycle Cost

Tankless water heaters have a longer life expectancy than traditional models (20 years or more in many cases). While the initial investment may be higher, you’ll save money in the long run with a tankless unit.

Energy Efficiency

Tankless water heaters only heat water when you need it. This can save a significant amount of energy, translating into lower utility bills each month. Many cutting-edge models are even eligible for rebates and energy-efficiency tax credits.

Heating Capabilities

The most well-known benefit of tankless water heaters is their ability to provide an endless hot water supply. Whether you’re taking a shower, doing laundry, or running the dishwasher, you’ll never have to worry about running out in the middle of your routine.
