The 10 Most Common Tankless Water Heater Questions (Answered for Acadiana Homeowners)
1. What is a tankless water heater and how does it work?
A tankless water heater, also known as a demand-type or instantaneous water heater, heats water only when you need it. Unlike a traditional tank that constantly heats and stores 40-80 gallons of water (wasting energy in the process—called “standby loss”), a tankless unit uses a powerful heat exchanger to heat the water as it flows through the unit on its way to your faucet or shower. It saves space, saves energy, and provides a continuous supply of hot water.
2. What are the main advantages of going tankless?
For homeowners near Lafayette and Youngsville, the main benefits are:
- Endless Hot Water: You’ll never run out, even with back-to-back showers and a load of laundry running.
- Energy Savings: Because it only heats water on demand, you can save money on your monthly utility bills. The U.S. Department of Energy estimates energy savings of 24–34% for homes using less than 41 gallons of hot water daily.
- Longer Lifespan: Tankless units can last 20 years or more with proper maintenance, nearly doubling the lifespan of a traditional tank.
- Space Savings: These compact units can be mounted on a wall, freeing up valuable closet or garage space.
3. How much money can I save with a tankless water heater?
While the savings vary based on your family’s water usage and your home’s energy source (gas or electric), the energy efficiency of a tankless unit translates directly to lower monthly gas or electric bills. In Louisiana’s climate, minimizing standby heat loss is a significant plus. The investment in a tankless unit is often offset over time by the long-term energy savings and doubled lifespan.
4. What is the process for a tankless water heater installation in the Lafayette, LA, area?
The process is highly customized to your specific home in Lafayette or Youngsville, and involves several vital steps to ensure code compliance and optimal performance. These steps include:
- Professional Sizing: Determining the correct Gallons Per Minute (GPM) needed for your family’s simultaneous hot water use.
- Fuel Source Check: Assessing or upgrading your gas line or electrical service.
- Venting Requirements: Installing the proper venting materials, especially for gas models.
- Code Compliance: Ensuring all installations meet local regulations and safety standards.
5. How do I properly size a tankless water heater for my home?
Proper sizing is crucial to ensure you get enough hot water. Our licensed plumbers look at the Gallons Per Minute (GPM) needed for your simultaneous hot water demands. For example, we’ll calculate the GPM required if two showers and the dishwasher are running at the same time. This is a vital step we handle during your consultation to recommend the perfect unit for your home in Acadiana.
6. Do tankless water heaters run on gas or electricity?
Tankless water heaters are available in both gas (natural gas or propane) and electric models. Gas-fired units are generally preferred for whole-house applications because they offer a higher flow rate (GPM), which is essential for larger families or homes with high hot water demand. Electric units are often better suited for point of use applications, like a remote sink. Our experts will assess your current setup in Lafayette to determine the most cost effective and efficient fuel source.
7. Will I get “instant” hot water?
This is the biggest misconception! A tankless water heater provides unlimited hot water, but it is not truly instant. The water still needs to travel from the unit, through the pipes, to your faucet. If you want to eliminate the wait for hot water, Hargrave’s Plumbing can install a hot water recirculation system, which keeps hot water moving through the pipes, giving you near instant access.
8. What maintenance is required for a tankless water heater in Acadiana?
Yes, maintenance is required! Due to the hard water often found in the Lafayette region, we strongly recommend an annual flush (or descaling) of your tankless unit. This process removes mineral buildup inside the heat exchanger, which is vital for maintaining efficiency and ensuring the 20+ year lifespan. Our Plumbing Assurance Plan includes an annual water heater flush to keep your system in top shape.
9. How long does a tankless water heater last?
With professional installation from Hargrave’s Plumbing and routine annual maintenance, a high-quality tankless water heater can last 20 to 25 years. This is a major long-term benefit compared to the average 10-15 year lifespan of a traditional tank unit.
10. What problems do tankless water heaters commonly have?
Most problems are related to improper sizing or lack of maintenance. Common issues include:
- Mineral Scale Buildup: As mentioned, this is a major issue in the Acadiana area’s hard water, but it’s easily solved with an annual flush.
- “Cold Water Sandwich”: This is a brief pause in hot water flow between uses, which can be minimized with proper installation and unit selection.
- Inadequate Flow: This happens when the unit is undersized for the home’s hot water demands, a mistake we ensure is avoided with our meticulous sizing assessment.
