What Code-Compliant Tankless Installation Actually Involves

A tankless water heater isn’t a drop-in replacement for a tank unit. Gas models typically require larger gas line sizing and dedicated venting that a standard tank heater doesn’t need. California also requires a permit for water heater installation, covering venting, gas line sizing, and safety valve installation, along with seismic bracing where it applies to the unit type.

This is where our credentials matter. We hold LA and Orange County certification for backflow testing and are RSO-certified, qualifications that apply directly to the gas line and backflow connection work a compliant installation demands. Most of our team members have been with us for 10 to 20 years, so the technician who shows up at your door has handled these jobs many times before.

Gas or Electric, Whole-House or Point-of-Use: Choosing the Right System

A tankless water heater heats water on demand as it flows through the unit rather than storing a reserve supply. Units mount on a wall and take up far less space than a storage tank. Beyond that shared trait, the options branch in two directions.

Whole-House vs. Point-of-Use
Whole-house systems supply hot water to every fixture and appliance in the home. Point-of-use units serve a single fixture, making them a practical addition where hot water delivery is slow.

Gas vs. Electric
Gas tankless units generally deliver higher flow rates but require adequate gas line capacity. Electric units skip the venting requirement but may need additional electrical panel capacity. We can assess your existing infrastructure before recommending a direction.

Why Long Beach Homeowners Are Upgrading to Tankless

The case for going tankless comes down to three things. First, you get continuous hot water on demand instead of a finite tank supply. Second, tankless units reduce standby heat loss, the energy wasted keeping stored water hot around the clock. Third, many systems last 15 to 20 years compared to 8 to 12 years for a conventional tank.

Long Beach Utilities offers a rebate program for residential customers who purchase and install a qualifying ENERGY STAR certified natural gas tankless water heater. That rebate can meaningfully offset up-front installation costs, and we can tell you whether the system you’re considering qualifies.
