Here are some recent tankless water heater installations we’ve completed throughout Tucson, Marana, & Oro Valley.





What is the best tankless water heater brand/manufacturer for Tucson Water?
After installing tankless water heaters for the past 15-years, we believe the best tankless water heaters come from Navien.
First and foremost, Navien is the only company that makes an “all stainless steel” unit. This allows their unit to last much longer than their competitors. Some other benefits exclusive to Navien are…
- Excellent technical support in the event of a problem. If you have an issue, they are always there to help.
- Their design makes it easier for field technicians to service and repair units. This cuts down on service costs and saves you money.
- Navien is the most recommended unit and the most preferred by our Tucson customers.
- Navien tankless units have the least amount of breakdowns compared to the other tankless systems we install.
- Their warranty process is seamless and straight-forward without any gimmicks.
- Our local plumbing supply vendors all carry Navien systems and parts in town. This means if a part fails, you don’t need to wait weeks for parts while being without hot water.
- Navien designs their units to be more resistant to the hard water effects of Tucson’s water supply. Simply put, we see Navien last longer and have less breakdowns than the competitors.

Here are the most frequently asked questions we receive from our Tucson customers regarding Tankless Water Heaters…
What size tankless water heater do I need for my home?
When sizing a tankless water heater, the temperature rise chart is the most important thing to look for. Often, manufacturers of tankless systems display a gallon per minute flow rate with their marketing materials. This flow rate they display, is the highest flow rate the particular system is capable of producing in summertime weather. What the manufacturers often leave out, is the flow rate varies with the incoming water temperature. Will your flow rate be the same in winter weather? No, it will not. This is because the incoming water temperature to your home will be colder than in the summer. Here is a temperature rise chart for a Navien 240A tankless system.

How much energy will I save going tankless?
This is difficult to answer objectively because energy savings is relative to the use and lifestyle of the property. Here is what the U.S. Department of Energy says about Tankless: https://www.energy.gov/energysaver/heat-and-cool/water-heating/tankless-or-demand-type-water-heaters
How does an electric tankless water heater compare to a gas tankless?
Electric tankless systems are built differently from gas tankless. In our 15-years of installing tankless water heaters, we see that gas tankless systems last much longer than electric tankless. We also see more breakdowns with electric tankless systems versus gas tankless systems. Whole house electric tankless water heaters are not energy efficient, nor are they energy star rated. Now, if you run your electric tankless from solar power, you can benefit from energy savings. Gas tankless systems are energy star rated and energy efficient up to 99%. Generally, gas tankless is a better purchase than electric tankless due to energy savings, performance, and longevity.
What is the downside of a tankless water heater?
Cost is the primary drawback to getting a tankless. The upfront cost of a tankless is more than a traditional tank water heater. Additionally, if you don’t have treated water (softener or some type of water filtration) the tankless will be susceptible to breakdowns due to mineral accumulation inside of the unit. Although tankless systems are designed in such a way to reduce hard water breakdowns, no tankless system is impervious to the effects of hard water. Annual maintenance is required if you don’t have treated water. If you do have treated water, you most often will only need maintenance every 4-years. Annual maintenance is generally $149.00, but is something that a homeowner can easily do themselves.
Is a tankless water heater worth the cost?
Whether it’s worth it or not is relative to the home. Is a tankless water heater good for every home? Not necessarily. The primary reason people buy a tankless is to avoid running out of hot water when they need it. However, many of our local Tucson customers go tankless to add a selling point to their property and increase their home value. A study from Zillow.com on home listing analysis found that homes with a tankless water heater sold for 4 percent more than their expected value.
