How do tankless water heaters work?

Tankless water heaters, also known as on-demand water heaters, heat water only when it is needed, eliminating the need for a storage tank. When a hot water tap is turned on, cold water flows through the unit, where it is quickly heated by either a gas burner or an electric heating element. This process provides a continuous supply of hot water, as the system heats the water as it passes through, ensuring you never run out, unlike traditional tank-style heaters. Tankless water heaters are more energy-efficient since they do not have to maintain a large reserve of hot water, reducing energy waste and lowering utility bills.

After years of looking for a good plumbing company, we have finally found our plumbers. Don was so professional, knowledgeable, and helpful. We had a vanity sink in our basement that had a slow leak that we didn’t notice until way too late. Don provided us good ideas to fix the leak in short term. Then came out a week later to install the brand new vanity and all new fixtures and piping. The result is beautiful and I am confident it was done right. We will definitely use Dalmatian Plumbing in the future.

From the moment he arrived, he was personable and even shared some laughs, making the whole experience enjoyable. He went above and beyond by providing me with excellent advice on selecting a more durable sink for my upcoming home lease, which I truly appreciated. The installation of the new sink and faucet was flawless – the sink sealant was applied so neatly, which shows real attention to detail. What truly impressed me was how he tidied up the faucet supply lines and even painted both the new drain and my existing garbage disposal drain to perfectly match in color. It's those little touches that make a huge difference! Donald is not only highly skilled but also genuinely funny and a pleasure to work with. I will definitely call him again for any future plumbing needs. Highly recommend!"

The team has reviewed the work to be done and provided quote that includes the labor and material for installation. The expectation was the job will be done as per new codes. The job was perfectly executed. The team also helped to pick the water heater from Lowe’s at no extra cost. Will definitely recommend this service.

After several "24/7" services did not return calls, Simon called and sent the best person imaginable. Jason responded in a timely manner and quickly diagnosed the problem. He was professional and efficient, but most importantly, very personable (he loved our labs!). He kept in touch to let us know the status of ordering a new, correct pump. Then, unlike most service professionals, managed expectations, showing up not only a day early, but 30 minutes ahead of schedule. He kept us informed every step of the way of the installation. He left everything cleaner than he found it. Where on earth do you find such a great professional? Call Dalmatian and ask for Jason, if you want a consummate professional and a great guy to boot!

We were hosting the grand opening of our new 13,000-square-foot center on a Saturday when—of course—the toilet clogged. We thought we had time to grab supplies and handle it ourselves, but by the time we got back… the smell had taken over the entire building. There was no fighting that stench alone, so we turned to Thumbtack and found Dalmatian Plumbing. Within no time, Jim showed up, quickly assessed the situation, and—before I could retreat to my office in embarrassment—he had already resolved the issue. Not only did he unclog the toilet, but he also cleaned it for us. The level of professionalism, speed, and care was beyond what we expected. Highly recommend Dalmatian Plumbing—especially if you're in a pinch and need fast, reliable, and courteous service. We’ll definitely be calling them again!

We had a great experience working with Christian, our plumber. From the moment he arrived, his calm and easygoing approach made us feel at ease. He quickly identified the root of the issue and handled it with professionalism and care. What really stood out was his patience—he took his time to make sure everything was done right, not rushing through any part of the job. Christian is not only skilled at what he does, but he also values service and takes the time to explain things clearly. We learned a lot just from talking with him, and it’s rare to find someone so open and generous with their knowledge. He’s genuine, respectful, and someone I’d trust to call again in the future. Highly recommended!

Tim was fantastic. Came for a simple toilet issue but helped correct a larger issue that could be my overall problem. I needed a new pressure reducing valve. My house was getting 120psi and should never be over 60lbs psi. Excellent work, professional and very nice guy. I’d refer Tim and... Tim was fantastic.

How is a tankless water heater installed?

Installing a tankless water heater involves several key steps to ensure proper operation and safety. First, the old water heater is removed, and the area is prepared for the new unit, which is typically wall-mounted to save space. Depending on whether the unit is electric or gas-powered, adjustments to the electrical wiring or gas lines may be necessary to meet the system's requirements. The plumbing is then connected to the water supply, and a venting system is installed for gas units to expel combustion gases safely. Finally, the unit is tested for leaks, proper function, and temperature settings, ensuring it delivers hot water efficiently and reliably. A licensed professional should always handle the installation to guarantee compliance with local codes and safety standards.

The Top Advantages of Tankless Water Heaters

Endless Hot Water Supply

Unlike traditional water heaters, which can run out of hot water, tankless water heaters provide a continuous supply of hot water on demand, ensuring that you will never experience cold showers again.

Energy Efficiency

Tankless water heaters only heat water when needed, reducing energy waste and lowering utility bills. This on-demand heating can result in significant energy savings compared to traditional water heaters, which constantly keep a tank of water hot.

Space-Saving Design

Without needing a large storage tank, tankless water heaters are compact and can be installed in various locations, freeing up valuable space in your home.

Longer Lifespan

Tankless water heaters generally last longer than traditional models, with a lifespan of up to 20 years or more. This durability makes them a wise long-term investment for homeowners.

Reduced Risk of Water Damage

Since no tank can leak or rupture, the risk of water damage from a tankless system is significantly lower, offering peace of mind and potentially lowering home insurance costs.

Frequently Asked Questions

Q What are the signs that my water heater needs repair or replacement?

There are several indicators that your water heater may need attention. Look out for rusty or discolored water, strange noises coming from the tank, a lack of hot water, or water leaking around the unit. If you notice any of these signs, it's best to contact a professional plumber to assess the situation.

Q How long do water heaters typically last?

The lifespan of a water heater can vary depending on the type of unit and maintenance. On average, traditional tank-style water heaters last around 8 to 12 years, while tankless water heaters can last up to 20 years. Regular maintenance and timely repairs can extend the life of your water heater.

Q Should I repair or replace my water heater?

The decision to repair or replace your water heater depends on the extent of the problem, the age of the unit, and the cost of repairs compared to a new installation. A professional plumber can evaluate the condition of your water heater and provide expert advice on the most cost-effective solution.

Q How can I maintain my water heater?

Regular maintenance is crucial to keep your water heater running efficiently. Flushing the tank annually to remove sediment buildup, checking the pressure relief valve, and inspecting the anode rod are some common maintenance tasks. It's also advisable to have a professional plumber perform a thorough inspection and maintenance service periodically.
