Tankless Water Heater Maintenance And Installation

Tankless Water Heater Maintenance and Installation

Tankless water heaters have become one of the most popular upgrades for homeowners looking to save energy, reduce utility bills, and enjoy endless hot water. Unlike traditional tank systems that constantly heat and store water, tankless systems heat water only when you need it. This makes them more efficient, longer-lasting, and better suited for modern homes. Whether you’re considering installing a new tankless system or maintaining the one you already have, understanding how they work can help you keep them running at peak performance—especially in areas like Melbourne, Palm Bay, and Viera, FL.

Why Choose a Tankless Water Heater?

Tankless water heaters, often called “on-demand” systems, heat water directly as it passes through the unit. This eliminates the need for a bulky tank and reduces heat loss that typically happens when stored water cools over time. With a tankless unit, homeowners enjoy consistent hot water, improved energy efficiency, and longer equipment life. Many modern systems also include advanced temperature controls and smart home features, making them convenient and reliable for daily use.

Switching to a tankless system can also help reduce your home’s energy consumption. According to the U.S. Department of Energy, tankless heaters can be 8%–34% more efficient than traditional tank models, depending on your household size and usage. Over time, this efficiency can translate into substantial savings on your monthly utility bills.

Installing a Tankless Water Heater

Tankless water heater installation is more complex than installing a standard tank system, which is why working with a licensed plumber is essential. These systems require proper sizing, adequate gas or electrical supply, correct venting, and careful placement to ensure safe and reliable operation.

During installation, your plumber will evaluate your home’s water usage to determine the correct unit size. For example, larger households or homes with multiple bathrooms may need a higher-capacity model to ensure consistent hot water during heavy use. The plumber will also check your existing gas line or electrical panel to make sure it can support the system. In many older homes, upgrades such as a larger gas line or dedicated circuit may be needed before installation.

Proper venting is another important part of tankless installation. Gas-powered systems require secure venting to safely release combustion gasses. Electric units require proper wiring and circuit protection. Once everything is in place, the installer will test the system, set the temperature, and ensure water flow is correct throughout the home.

The Importance of Tankless Water Heater Maintenance

Even though tankless systems are known for their durability, they still require routine maintenance to keep them running efficiently. Over time, minerals from hard water can build up inside the heat exchanger, reducing flow, lowering efficiency, and eventually causing system damage. Since many areas in Brevard County have hard water, annual maintenance is especially important.

A typical maintenance visit includes descaling the unit, cleaning the filter, checking burners or heating elements, inspecting venting, and ensuring the system operates safely. Skipping maintenance can lead to expensive repairs, lower efficiency, or premature system failure. Regular care helps extend the lifespan of the heater, often allowing tankless units to last 20 years or more—which is about double the lifespan of traditional tank heaters.

If you already own a tankless system, check your manufacturer’s maintenance guidelines. Brands like Rinnai, Navien, and Noritz often recommend flushing the system once a year to remove calcium and mineral buildup. You can also review general maintenance tips here:

Are Tankless Heaters Worth It in Florida?

Tankless water heaters are a great option for Florida homes, especially those located in humid and coastal areas. Traditional tank heaters are more prone to rust and corrosion in Florida’s climate, while tankless systems are less affected because they do not store water. Their compact design is ideal for smaller homes and condos throughout Melbourne, Palm Bay, Viera, and Satellite Beach where space may be limited.

Because tankless systems heat water as needed, they also reduce the amount of energy lost due to standby heat—something that’s especially beneficial for larger families or homes that use hot water throughout the day. Many Florida homeowners choose tankless to reduce utility bills, free up storage space, and avoid frequent tank replacements.
