Debunking 5 Common Tankless Water Heater Myths

Tankless water heaters have gained popularity as an energy-efficient and space-saving alternative to traditional water heaters. However, despite their growing adoption, several myths and misconceptions persist, causing confusion among homeowners. In this article, we will debunk five common myths about tankless water heater company Jupiter and provide you with the facts to make an informed decision.

Myth #1: Tankless Water Heaters Provide Instant Hot Water

The Truth: While tankless water heaters heat water on demand, they do not provide instant hot water. The misconception arises because they do not store hot water like traditional tanks. When you turn on a hot water tap, the heater activates and begins to heat the water, but it still takes a few seconds or more for the hot water to reach the fixture, depending on the distance between the heater and the faucet.

Solution: If you want near-instant hot water, consider installing a recirculation pump. This device helps circulate hot water through the plumbing system, reducing wait time and water waste.

Myth #2: Tankless Water Heaters Can’t Supply Enough Hot Water for a Whole Household

The Truth: Many people believe that tankless water heaters cannot handle multiple hot water demands at the same time. In reality, a properly sized tankless water heater can supply hot water to multiple fixtures simultaneously without running out.

The key factor to consider is the flow rate, measured in gallons per minute (GPM). If your household frequently uses multiple appliances that require hot water at the same time (e.g., showers, dishwashers, and washing machines), you should choose a model with a high enough GPM rating to meet your needs.

Solution: To ensure adequate hot water supply, calculate your home’s peak hot water demand and select a tankless unit that meets or exceeds this requirement.

Myth #3: Tankless Water Heaters Are Too Expensive

The Truth: While the upfront cost of a tankless water heater is generally higher than that of a traditional storage tank, it can lead to long-term savings on energy bills. Traditional water heaters continuously heat and store hot water, leading to energy waste. In contrast, tankless models heat water only when needed, reducing energy consumption.

According to the U.S. Department of Energy, tankless water heaters are 24%–34% more energy-efficient for homes that use less than 41 gallons of hot water daily. For households with higher usage, efficiency improvements can still range between 8% and 14% compared to conventional water heaters.

Solution: Consider the long-term savings. Although the initial investment may be higher, lower energy bills and longer lifespan (typically 20+ years compared to 10-15 years for traditional tanks) make tankless water heaters a cost-effective option over time. Additionally, many states offer rebates and tax incentives for energy-efficient upgrades.

Myth #4: Tankless Water Heaters Are Only Suitable for Small Homes

The Truth: While tankless water heaters are ideal for small homes and apartments due to their compact design, they can also be used in large homes. Modern high-capacity tankless water heaters, or multiple-unit installations, can handle the demands of large households efficiently.

Larger homes with multiple bathrooms can benefit from either a high-GPM unit or multiple tankless water heaters strategically placed throughout the house.

Solution: If you have a larger home, consult a professional to determine whether a single high-capacity unit or multiple smaller units will best suit your household’s needs.

Myth #5: Tankless Water Heaters Require No Maintenance

The Truth: Like any appliance, tankless water heaters require regular maintenance to operate efficiently and last as long as possible. One of the most common issues affecting tankless water heaters is mineral buildup, especially in areas with hard water.

Without proper maintenance, limescale can accumulate in the heat exchanger, reducing efficiency and potentially leading to costly repairs. Regular descaling and flushing help keep the system running smoothly.

Solution: Schedule annual maintenance, including descaling and cleaning filters, to keep your unit in top shape. If you live in an area with hard water, consider installing a water softener to reduce mineral buildup.

Final Thoughts
