What Is a Tankless Water Heater?

Instead of storing 40 or 50 gallons of hot water in a tank, a tankless unit heats water as it flows through, right when you turn on the tap. There’s no tank to run out and no waiting for a large tank to reheat after a full house uses hot water back to back.

Why More East Valley Homeowners Are Switching to Tankless

01
Endless hot water
With a properly sized unit, you're not limited by tank capacity. Back-to-back showers, laundry, and dishes at the same time stop being a problem.
02
Smaller footprint
Tankless units mount to a wall and take up a fraction of the space a traditional tank does, which is useful in a garage or smaller utility closet.
03
Lower standby energy use
A traditional tank heats and reheats water constantly, even when nobody's using it. A tankless unit only heats water when you need it, which can mean real savings over time depending on your household's usage.
04
Longer lifespan when maintained
Tankless units often last longer than traditional tanks, especially with the annual maintenance we'll cover below.

Is Tankless Right for Your Household?

Tankless tends to make the most sense for:
  • Larger families running multiple showers, laundry, and dishwashing close together
  • Homeowners who've dealt with running out of hot water regularly
  • Anyone doing a remodel or new build who wants to save space
  • Households looking to reduce long-term energy costs, even with a higher upfront cost
It's a bigger upfront investment than a standard tank, so we'll walk you through real numbers for your specific household before you decide, not just push the upgrade because it's a bigger job.

The One Thing Hard Water Changes About Tankless Units

Here’s something a lot of companies don’t mention clearly: tankless water heaters need more regular maintenance in hard water areas like Chandler than they do elsewhere.

Because water flows through a small heat exchanger instead of sitting in a large tank, mineral buildup from Chandler’s hard water (typically 12 to 20 grains per gallon) can affect that exchanger faster than it would affect a traditional tank.

The fix is simple: an annual descaling flush keeps the unit running efficiently and protects your investment.

We’ll explain this clearly when we install your unit, and we’re happy to handle that annual maintenance so you’re not left guessing.

Gas vs. Electric Tankless Units

We’ll help you figure out which type — and which flow rate — actually fits your home’s hot water demand, rather than installing whatever’s easiest for us.

Gas tankless water heaters
generally support higher flow rates, which makes them a strong fit for larger East Valley homes running multiple fixtures at once.
Electric tankless water heaters
can be a good fit for smaller households or situations where running a new gas line isn't practical.

Our Tankless Installation Process

01

We assess your household's hot water needs
Number of bathrooms, typical usage, and whether you're converting from an existing tank or building new.

02

We recommend the right unit and flow rate.
Sized correctly for your home, not oversized or undersized.

03

We give you a clear, upfront price
Including any gas line or electrical work the conversion requires.

04

We explain maintenance
Including why annual descaling matters here specifically, and how to schedule it.
05
We install and test the unit
Proper venting, connections, and a full test before we call the job done.

Converting From a Traditional Tank

If you currently have a tank water heater and want to switch to tankless, we handle the full conversion — removing and disposing of your old tank, running any additional gas line or electrical work needed, and installing the new unit properly vented and connected. We’ll walk you through what the conversion involves and what it costs before any work starts.

What Tankless Installation Typically Costs

Tankless units generally cost more upfront than a traditional tank, both for the unit itself and for installation, especially if a conversion requires new gas line or electrical work. That said, many households recoup part of that difference over time through lower standby energy use and a longer unit lifespan.

We’ll give you a full, itemized estimate that includes the unit, any required gas or electrical modifications, and installation, so you’re comparing real numbers rather than guessing at a rough estimate.

Common Tankless Installation Mistakes We Help You Avoid

Undersizing the unit
A tankless water heater that's too small for your household's actual peak demand will still leave you running out of hot water, just for a different reason than a tank running dry. We calculate real flow-rate needs based on your bathrooms and typical usage before recommending a unit.
Skipping proper venting
Tankless units, especially gas models, require specific venting to operate safely and efficiently. Improper venting installed by an inexperienced installer can cause performance issues or safety concerns down the line.
Ignoring hard water maintenance
As covered above, skipping annual descaling in a hard water area like Chandler shortens the unit's lifespan significantly. We make sure you understand this maintenance requirement clearly from day one, not after a problem shows up.
Choosing the wrong fuel type for the home's setup
Sometimes electric makes more sense than gas, or vice versa, depending on what's already available at the installation site. We evaluate your home's existing setup before recommending a direction.

Rebates and Incentives for Tankless Water Heaters

Depending on the utility provider and time of year, there are sometimes rebate programs available for upgrading to a high-efficiency tankless water heater. We can let you know what’s currently available when you call for your estimate, since these programs change from year to year.

Tankless Water Heaters and Home Value

Beyond the day-to-day convenience, a tankless water heater is increasingly seen as a desirable upgrade by home buyers, particularly in a market like the East Valley where energy efficiency and modern systems carry real weight. If you’re planning to sell your home in the next several years, a properly installed and maintained tankless system can be a meaningful selling point, especially compared to an aging traditional tank.

New Construction and Tankless Installation

If you’re building a new home in areas like Queen Creek or Gilbert, installing tankless from the start avoids the cost of a later conversion and lets your builder plan the gas line, venting, and electrical work around the unit from day one. We work with homeowners and builders on new construction tankless installations, making sure the system is sized correctly for the home’s final layout and household size before it’s ever lived in.

Tankless Water Heaters and Multiple Bathrooms

A common question from larger East Valley households is whether one tankless unit can really keep up with two or three bathrooms running at once. The honest answer depends on the unit’s flow rate and your home’s layout. In some larger homes, we recommend two smaller tankless units installed at different points in the house rather than one oversized unit trying to serve the entire property. We’ll walk through this option with you if it fits your home better than a single central unit.
