Why Many Are Moving Away from the Tank

In the United States, we have grown accustomed to having a 40-to-50-gallon tank sitting in our homes, occupying roughly 9 square feet of valuable floor space. However, tankless technology is the standard used worldwide for its efficiency and compact design. It is primarily in the U.S. that we expect to have large storage tanks taking up room in a garage or hall closet.

Our clients choose to make the switch because we combine technical expertise with an A+ Better Business Bureau rating and a commitment to honest communication. In fact, we have personally used tankless technology for decades, and once you experience the benefits, it is hard to imagine going back to a traditional one.

Professional Tankless Installation

Installing a tankless unit is a sophisticated process that requires precise gas line sizing, specialized venting, and electrical adjustments. Our team understands the specific architectural needs of our local properties, from historic ranch homes to modern new builds.

Our installation process includes:

Precision sizing. Calculating the exact flow rate your household requires.
Operational walkthrough. Ensuring you understand how your new unit functions.
Preventative education. Showing you simple ways to monitor your system’s health.

3 Simple Steps to Get Started

The Benefits of On-Demand Hot Water

Traditional heaters constantly reheat water 24/7, leading to significant "standby" energy loss. Tankless systems only operate when there is an active demand. When you turn the faucet off, the energy consumption stops.

Endless Supply, Smaller Footprint

The primary advantage is an endless supply of hot water. Because the water is heated as it flows, you don't have to worry about the "last person to shower" getting a cold surprise. These systems are fully capable of filling large soaking tubs without the water turning cold halfway through.

Furthermore, because these units are wall-mounted and significantly smaller than traditional tanks, you can free up room in your garage or hall closet for better use.

Significant Energy Savings

Heating water is one of the largest expenses on a utility bill. By switching to an on-demand system, a family can experience energy savings of 30–50%. By eliminating the need to keep 50 gallons of water hot around the clock, you lower your monthly overhead while reducing your environmental footprint.

Choosing the Right Fuel Source

We provide tailored solutions based on your home’s existing infrastructure rather than a "one-size-fits-all" approach.

Natural Gas & Propane Systems

We feature Noritz and Takagi systems, which are world-renowned for their durability. These are excellent choices for homes with existing gas lines or larger households with high peak-demand for hot water.

Electric Tankless Systems

For all-electric homes, we install Stiebel Eltron units.

These are particularly effective for:

Solar-powered homes. If you employ a solar array, electric tankless heaters allow you to utilize your own generated power to heat your water, significantly driving down costs.
The transition to electric. They serve as a simple first step for homeowners looking to move away from gas appliances toward a fully electric lifestyle.

Ways to Care for Your System

Tucson is known for "hard water," which contains high levels of calcium and magnesium. While tankless heaters are built to last, they require a little specific care to stay efficient in our desert climate.

Annual descaling. Have a professional flush the unit once a year. This removes the mineral scale buildup that naturally occurs on the heating elements.
Check the in-line filter. Most tankless units have a small screen designed to catch debris. Checking this periodically ensures your water flow remains strong and steady.
Monitor error codes. If your unit’s digital display shows a code, don't ignore it. Most are simple sensor alerts that can be fixed quickly before they turn into larger repairs.
Consider a water softener. To further extend the life of your heater, many of our clients pair their tankless system with a water conditioning or softening system to keep the internals pristine.

Whether you want to save space or enjoy the luxury of a hot bath that never runs cold, The Solar Store is here to help. Call us today at (520) 341-2286 to discuss your options or schedule a service.

Hear From Our Customers

For people "starting from zero" this was a huge help to us.
“Katharine - Thanks to you and the team for getting our solar set up promptly and professionally. I don't have enough good things to say about Kevin, the teams who conducted the installations, and your own involvement. All our friends who got solar done (or tried) have horror stories about scams and unprofessional behavior; it put us off from trying this for a while. We were at first relieved and then very happy. Everyone we interacted with was friendly, professional and knowledgeable about the process, technology and government requirements. For people "starting from zero" this was a huge help to us.”
