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!"

It’s 5 star. The job was to replace the water heater and expansion tank that I have provided. 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!

Understanding How Tankless Water Heaters Operate

Tankless water heaters, often called on-demand systems, heat water only when it's needed instead of storing it in a tank. When you turn on a hot water tap, cold water runs through the unit, where a gas burner or electric heating element quickly warms it. This process delivers a steady flow of hot water for as long as you need it, unlike traditional tank models that can run out.

Because they don't have to maintain a large tank of hot water around the clock, tankless systems are more energy-efficient and can help lower utility costs. Homeowners often find them especially useful for households with higher hot water demands or for those looking to save space, since these units are compact and wall-mounted.

The Tankless Water Heater Installation Process

Installing a tankless water heater is a detailed process that ensures the system operates safely and efficiently. The first step is removing the old unit and preparing the area for the new one, which is usually mounted on the wall to save space. For gas-powered models, venting is installed to direct combustion gases outdoors, while electric units may require upgraded wiring to handle the higher power demand. Once the plumbing connections are in place, the system is carefully tested for leaks, performance, and accurate temperature control.

Because proper installation involves electrical, gas, and plumbing adjustments, it's a job best left to licensed professionals. A certified installer not only ensures the system is set up correctly but also guarantees compliance with local codes, helping homeowners get the most reliable performance from their new water heater.

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.
