4 Frequently Asked Questions About tankless water heaters

  • Are tankless water heaters more energy-efficient than traditional tank-style water heaters?

    Yes, tankless water heaters are generally more energy-efficient because they only heat water on-demand, eliminating the standby energy loss associated with traditional tank-style heaters.

  • How do I determine the right size and capacity for a new tankless water heater during installation?

    The size and capacity of a tankless water heater should be based on your household’s hot water demands. Our experts can assess your needs and recommend a unit that provides sufficient hot water for your usage patterns.

  • What is the typical lifespan of a tankless water heater, and when should I consider replacing it?

    Tankless water heaters typically have a longer lifespan, around 20 years or more, compared to traditional tanks (10-15 years). You may consider replacement when your unit reaches the end of its lifespan or if you’re experiencing frequent breakdowns or reduced efficiency.

  • What are the advantages of professional installation services for tankless water heaters?

    Professional installation ensures proper sizing, safe connections, and compliance with local building codes. It also helps maintain the manufacturer’s warranty and guarantees optimal performance and safety.
