Navigating the Myths and Facts About Tankless Water Heaters Jul 07, 2026

Tankless water heaters have been gaining popularity as an efficient alternative to traditional water heaters. Despite their advantages, several myths persist about these appliances. At Absolute Plumbing and Drains LLC, we believe it's important for customers to make informed decisions, so we’re here to help you navigate the myths and facts about tankless water heaters.

To begin, let's address one of the most common myths: "Tankless water heaters provide instant hot water." While it is true that tankless systems heat water on demand, they do not deliver instant hot water to your taps. The time it takes for hot water to travel through pipes remains unchanged, so while waiting for the water to arrive, energy savings are achieved by eliminating "standby heat loss" associated with tanked models.

Another prevalent myth suggests that "tankless water heaters are maintenance-free." In reality, regular maintenance is key to ensuring the longevity and efficiency of any appliance, including tankless models. Over time, mineral deposits can form, especially in areas with hard water. This buildup can reduce efficiency and even damage the system. At Absolute Plumbing and Drains LLC, we recommend annual maintenance checks to keep your system in tip-top condition.

Let's discuss the belief that "tankless water heaters cannot meet the hot water needs of a large household." The truth is, tankless water heaters are available in several sizes and capacities. When properly sized and installed, a tankless system can comfortably meet the demands of multiple showers, laundry machines, and dishwashers running simultaneously. Our team is adept at evaluating your household needs to recommend and install a system that performs efficiently under peak demands.

One economic consideration often misunderstood is the cost factor, as myths suggest: "Tankless water heaters are too expensive." While the upfront cost for tankless water heaters can be higher than for traditional models, they are more cost-effective over time. Their longevity and energy efficiency deliver savings on utility bills, making them an investment that pays off in the long run. In fact, according to the U.S. Department of Energy, tankless systems can be 24-34% more energy-efficient than conventional tank heaters, especially in homes that use up to 86 gallons of hot water daily.

Furthermore, there's the misconception that "tankless water heaters are complicated to install and require extensive home modifications." It's true that the installation process is different, but not necessarily more complicated. At Absolute Plumbing and Drains LLC, we have the expertise to seamlessly integrate a tankless water heater into your existing plumbing system with minimal disruption to your home.

In conclusion, understanding the realities of tankless water heaters can help you make an educated decision about your home’s plumbing.
