Jake was professionally friendly, clear with his assessment and generous with his time giving me the overview. After 3 plumbers couldn’t fix the issue he was efficient and thorough. He also struck me as well read, articulate and Heritage is lucky to have this professional on the team. Ive already recommended Heritage to my client for plumber services. Elated sums up my experience. Thank you DebSmith Weare NH

Frequently Asked Questions

  • What are the benefits of a tankless water heater?

    Tankless water heaters heat water on demand, so you never run out during heavy usage. They are more energy efficient because they only heat water when needed, take up less space, and typically last 20 years or more compared to 8 to 12 years for traditional tank heaters.

  • Can my Maine home switch from a tank to a tankless water heater?

    In most cases, yes. Heritage can retrofit your home for a tankless water heater. The installation may require upgrades to your gas line, venting, or electrical supply. Our licensed plumbers assess your home and explain what is needed before work begins.

  • How long does a tankless water heater last?

    Tankless water heaters typically last 20 years or more with proper maintenance, significantly longer than traditional tank models. Regular descaling and filter cleaning help maximize efficiency and lifespan.

  • Does Heritage service and repair tankless water heaters in Maine?

    Yes. Heritage provides complete tankless water heater services including installation, maintenance, descaling, and repair. Whether your unit is not producing hot water, showing an error code, or due for maintenance, our licensed plumbers can help.

  • What size tankless water heater does my home need?

    The right size depends on the number of fixtures and appliances that may use hot water simultaneously and the groundwater temperature in your area. Maine’s cold groundwater temperatures require a more powerful unit than warmer climates. Heritage will calculate your demand and recommend the correct size.
