    Space Saving Tankless Water Heaters

    Tankless water heaters heat water on demand, so you never run out. They save space, reduce energy consumption and last longer than traditional tanks. We provide expert guidance from selection through installation.

    Explore Tankless Water Heater Services

    Why Choose Tankless?

    Tankless systems only heat water when you need it. This efficiency can lower energy bills and reduce standby heat loss common in storage tanks. With proper maintenance, tankless units can last 15 to 20 years.
    Call to Get Your Own

    How Tankless Systems Work

    When you turn on a hot water tap, cold water flows through a heat exchanger where it is warmed by electric elements or a gas burner. Because there is no storage tank, hot water is available continuously. Choosing the right size system ensures adequate flow for simultaneous showers, appliances and fixtures.

    Installation Services

    We assess your home’s water use to size the unit properly. Installation may involve upgrading gas lines or electrical circuits and ensuring adequate ventilation. Our technicians follow manufacturer guidelines and local codes to ensure safety and performance.

    Maintenance and Repair

    Tankless units need descaling to remove mineral build‑up, especially in areas with hard water. Annual maintenance includes cleaning filters, checking burner operation and ensuring venting is clear. If problems arise, our team can replace sensors, valves or heat exchangers to restore reliable operation.

    Service Plans

    Protect your investment with a service plan that includes annual maintenance, priority scheduling and discounts on repairs. Regular care keeps your tankless heater running efficiently and prolongs its lifespan.

    This is not the first time I have called First Call. They replaced my old furnace and checked my existing A/C. This time my old hot water heater needed to be changed. As a much-appreciated perk, the plumber also tested my sump pump and explained how I could do it at no additional charge! The installers arrived on time, used tarps to protect our home, and explained what they had done.

An additional reason I called First Call again, is their active participation in community events. They give back to our community wherever possible. I would not hesitate to call them again.

    Tankless Water Heater FAQs

    How long do tankless water heaters last?

    With proper maintenance, tankless units often last 15 to 20 years.

    Can a tankless heater handle multiple showers at once?

    Yes, provided it is sized correctly. We assess your home’s hot water demand to select the right unit.

    Is a tankless heater more efficient than a tank?

    Because it heats water only when needed, a tankless unit typically uses less energy and eliminates standby heat loss.

    What maintenance is required?

    Annual descaling, filter cleaning and vent inspection are recommended to prevent mineral build‑up and ensure safe operation.

    Do I need to upgrade my gas or electrical service?

    Larger tankless units may require higher gas flow or electrical capacity. We evaluate your utilities during the consultation.

    Can I convert from a tank to a tankless system?

    Yes. Our plumbers can remove your old tank, modify piping and install a tankless unit tailored to your household’s needs.
