Frequently Asked Questions

How long does a tankless water heater installation take?

Most installations are completed in one day. In some cases, gas or venting upgrades may add a few hours, but we’ll give you a clear timeline before work begins.

Can I replace my tank water heater with a tankless unit?

Yes. We specialize in conversions from tank to tankless. We’ll assess your gas supply, venting path, and water system to ensure safe, efficient operation.

What are the benefits of a tankless water heater?

Endless hot water, lower energy bills, compact size, and longer lifespan compared to traditional tank heaters. You only heat water when you need it.

Do I need a permit for a new installation?

Yes, and we handle it for you. We obtain all required permits and ensure the installation meets or exceeds California code

What brands do you install?

We install and service Navien, Noritz, Rinnai, Takagi, Rheem, and AO Smith. We’ll recommend the best model for your home, water usage, and budget.

Will my gas line need to be upgraded?

Possibly. Tankless systems require higher BTU input. We’ll measure your gas supply and, if needed, install an upsized line for safe and efficient performance.

How much space will I save?

Tankless units mount to a wall and are about the size of a carry-on suitcase, freeing up closet or garage space once used by bulky tanks.

How do I maintain my new tankless system?

We recommend annual descaling or flushing to remove mineral buildup, especially in hard water areas. Elder & Young offers maintenance plans for convenience.

Can you install water treatment to protect my tankless heater?

Yes. We install filters and softeners that prevent scaling and corrosion, helping your system perform better and last longer.

Do you offer financing for installations?

Yes. We have flexible payment plans to make your new tankless system affordable today without draining your savings.

Our No Cold Shower Guarantee

Your new tankless water heater will be installed properly, safely, and up to California plumbing code. It will deliver consistent, reliable hot water throughout your home. If your system fails to perform correctly due to our installation, we will return promptly, fix the issue, and cover all labor and materials at our own expense during our workmanship warranty period. No hidden fees, no excuses.
