Got Questions

Answers to Your Tankless Water Heater Questions

Tankless water heaters offer superior efficiency and unlimited hot water, but many homeowners have questions before making the switch. Here are the most common questions we receive:

How does a tankless water heater work?

A tankless water heater heats water on demand rather than storing and continuously reheating water in a tank. When you turn on a hot water tap, cold water flows through a heat exchanger, where it is rapidly heated by gas burners or electric elements before being delivered to your faucet. This process ensures unlimited hot water while reducing energy consumption.

What are the benefits of installing a tankless water heater?

Installing a tankless water heater provides:

  • Unlimited hot water – No more running out of hot water
  • Energy efficiency – Reduce energy use by up to 30%
  • Longer lifespan – Tankless units last 20+ years with proper maintenance
  • Space-saving design – Compact and wall-mounted, freeing up storage space

If you’re looking for a more efficient and reliable hot water solution, a tankless system may be the best option.

How long does a tankless water heater last?

With proper maintenance and annual descaling, tankless water heaters can last 20+ years—nearly twice the lifespan of traditional water heaters. 

Do tankless water heaters work for large families?

Yes! Tankless water heaters can be sized to accommodate large households with high hot water demand. The right unit is based on flow rate (GPM) and the number of simultaneous water uses (e.g., showers, dishwashing).

Our experts can help determine the best tankless model for your home.

How much does a tankless water heater installation cost?

The cost of tankless water heater installation varies based on:

  • Type of unit (gas or electric)
  • Size and capacity needed for your home
  • Plumbing modifications or venting requirements
Where can I find tankless water heater service near me? How do I find reliable tankless water heater installers?

Finding experienced tankless water heater installers is essential for proper setup and long-term performance. Look for licensed professionals with experience in tankless system installation, gas line connections, and venting requirements. Always check for certifications, customer reviews, and manufacturer partnerships when vetting a team. 

What is involved in installing a tankless water heater?

When you install a tankless water heater, the process includes:

  • Assessing your home’s hot water needs to determine the right system size
  • Upgrading gas or electrical connections to meet the unit’s power demands
  • Mounting the tankless water heater in an appropriate location
  • Ensuring proper venting and drainage for gas models
  • Testing system flow and performance to confirm efficiency

Our experts at 365 Solutions provide full-service tankless water heater installation with upfront pricing and guaranteed results.

How often should I service my tankless water heater?

Regular tankless water heater servicing is essential for efficiency and longevity. Most manufacturers recommend annual maintenance, which includes:

  • Flushing the system to remove mineral buildup
  • Inspecting the heating elements and burner for performance issues
  • Checking gas lines, venting, and electrical components
  • Ensuring proper water pressure and flow rate

Neglecting maintenance can lead to reduced efficiency, longer heating times, and potential system failures. Our tankless water heater service plans help keep your unit running at peak performance.

Where can I find tankless water heater repair near me?

If you’re searching for tankless water heater repair, it’s important to choose a team experienced in diagnosing and repairing tankless systems. Common tankless water heater problems include:

  • Fluctuating water temperatures
  • Error codes on the control panel
  • Ignition or burner failure
  • Clogged inlet screens or mineral buildup

We provide fast and reliable tankless water heater repairs, restoring your system to full efficiency. Whether you have a gas or electric tankless water heater, our technicians have the expertise to troubleshoot and fix the issue quickly.

Do tankless water heaters require more maintenance than traditional water heaters?

Tankless water heaters typically require less frequent repairs than traditional systems, but regular maintenance is still essential for long-term performance. Over time, mineral buildup from hard water can affect efficiency, especially if your home’s water has high calcium or magnesium levels. To prevent scaling, we recommend servicing a tankless water heater at least once a year. This includes flushing the system, checking for clogs, and inspecting the heating elements. Regular maintenance helps extend the lifespan of your tankless water heater and keeps it running efficiently.
