Tankless Water Heater Installation in San Clemente: Recent Navien Upgrade for Endless Hot Water

Just finished installing a new Navien tankless water heater at a home right here in San Clemente. The homeowners were tired of running out of hot water during showers or when the dishwasher and sink were both going, so we upgraded them to a high-efficiency tankless system that delivers on-demand hot water whenever they need it.

Tankless units like this Navien have become one of the most popular upgrades we do in South Orange County. No bulky storage tank taking up space in the garage or closet, better energy efficiency, and never having to wait for the water to heat up again.

Why Homeowners in San Clemente Are Switching to Tankless

Traditional tank water heaters store 40–50 gallons and have to keep reheating that water all day — even when no one’s using it. A tankless system only heats water as it flows through the unit, which means:

• Endless hot water — Run the shower, dishwasher, and kitchen sink at the same time with no cold surprises.

• Space savings — This compact Navien unit fits neatly on the wall (see the photo above).

• Lower energy bills — Many South OC homeowners see 20–40% savings on their gas bill because the unit isn’t constantly reheating stored water.

• Longer lifespan — With proper installation, these systems often last 20+ years compared to 8–12 years for a standard tank.

The Installation – Done Right from Day One

During this job, I made sure every connection was done carefully and cleanly:

• Properly sized and configured the gas line for maximum flow

• Installed high-quality water lines and shut-off valves for easy future service

• Set up the venting correctly (critical for safety and efficiency with a

  condensing unit like the Navien)

• Secured everything neatly so the install looks as good as it performs

A clean, organized job isn’t just about looks — it makes maintenance easier down the road and helps the system run at peak efficiency for years.

Here’s how the finished install turned out:
