Tankless Isn’t Timeless: Why Maintenance Still Matters

August 4th, 2025

Tankless water heaters, often referred to as on-demand water heaters, have gained popularity due to their energy efficiency, space-saving design, and virtually limitless hot water supply. These systems bring water into the unit only when there is demand, instantly heating cold water as it flows through the heat exchanger. As cold water enters the system, it is rapidly heated on demand, allowing the unit to produce hot water continuously for as long as needed. This means you can enjoy continuous use, such as taking a shower, without running out of hot water. Typically, these systems can provide hot water at a rate of 2–5 gallons per minute, depending on the model and water temperature.

There are different types of tankless water heaters, including electric, gas, condensing, and non condensing models. Electric tankless water heaters are typically used for point-of-use applications due to their lower flow rates, while condensing models offer higher efficiency compared to non condensing units by utilizing advanced technology to recover more heat. Gas-fired tankless water heaters, on the other hand, produce higher flow rates than electric ones, making them a better choice for households with higher hot water demands. When selecting a unit, consider the flow rate (measured in gallons per minute) to ensure it can supply enough hot water for multiple fixtures, like a shower, running at the same time.

Energy efficiency is a key benefit, and ENERGY STAR certified models help identify the most efficient options. The choice of fuel—gas, propane, or electric—impacts both efficiency and installation requirements. Proper installation is crucial: gas models require safe and code-compliant gas lines, and all units should be installed on a suitable wall (interior or exterior) by a licensed professional to ensure safety. Local climate also affects which system is best for your home, as it can influence performance and installation needs. For instance, gas tankless water heaters are generally preferred in colder climates due to their efficiency and superior heating performance.

To improve hot water delivery and reduce cold water waste in pipes, some systems include a recirculation pump. Regular maintenance is essential to prevent mineral buildup, especially in hard water areas, which helps maintain efficiency and prolongs the life of the unit. Most manufacturers recommend yearly descaling for tankless water heaters unless the water is very soft. While tankless water heaters generally last longer than traditional tanks, they will eventually need to be replaced, though replacement is less frequent. Upgrading and replacing an old water heater with a tankless model can improve efficiency and save space, but always prioritize safety by using a professional for installation and maintenance.

Let’s dispel that myth and explore why regular maintenance is essential to keeping your tankless water heater in Gibsonia running efficiently and reliably.
