Tankless FAQs

  • Do I need to upgrade my gas line to install a tankless water heater?

    In many cases, yes, because tankless units require a higher burst BTU input than standard tank heaters to heat water on demand. Owner Josh Perez evaluates your existing gas line diameter during your free estimate to determine if an upgrade is required.

  • How often does a tankless water heater need to be flushed in Southern California?

    Due to hard water across Santa Clarita and Los Angeles County, tankless units should be flushed with a descaling solution once every 12 months. Annual flushing removes scale deposits from the heat exchanger to maintain efficiency and protect your warranty.

  • Will a tankless water heater give me instant hot water at every tap?

    Tankless units provide continuous hot water that never runs out, but cold water residing in your pipes must still clear out before hot water arrives at distant faucets. A dedicated recirculation pump can be installed to deliver instant hot water at every fixture.

  • What is the lifespan of a tankless water heater compared to a standard tank?

    With routine annual maintenance, high-efficiency tankless water heaters often last 20 years or more, whereas traditional tank units typically last between 8 and 12 years.

  • Why is my tankless water heater displaying an error code?

    Error codes signal specific issues such as restricted air intake, mineral scale buildup, flame failure, or gas supply pressure drops. Contacting a qualified C-36 plumbing specialist allows for fast, accurate diagnostic testing.

  • Are tankless water heaters worth the higher initial installation cost?

    Yes, tankless systems lower monthly energy costs by eliminating standby heat loss and last twice as long as tank units, making them a smart long-term investment. You also gain valuable floor space in your garage or utility room.
