Why Tankless Water Heaters Are Becoming the Top Choice for Homeowners in Costa Mesa

Smart design, reliable comfort, and lower energy costs for years to come

Today’s tankless water heaters are not a luxury item, they’re the smart choice for efficiency and comfort. Old-style tank heaters waste energy by reheating stored water, while tankless systems heat water instantly as you use it.

These are the main benefits that make homeowners switch to tankless water heaters.

  • Unlimited Hot Water – Enjoy nonstop hot water for families, long showers, and daily routines
  • Smart Energy Savings – Save money by heating water only when needed
  • Small Footprint – Free up space with a wall-mounted tankless system
  • Long Lifespan – Get decades of dependable performance from your tankless system
  • Clean, Fresh Water – Enjoy cleaner, fresher water every time you turn on the tap
  • Eco-Friendly – Lower energy use means a smaller carbon footprint and cleaner operation

Whether your current water heater is leaking, slow to heat, or simply outdated, our expert team can install a modern tankless system that fits your home perfectly.

And if you are interested in a standard tank water heater, we can do that too.

Frequently Asked Questions

What warranties do I get

Manufacturer warranties vary by model. We register your unit and include our written workmanship warranty plus the No Cold Shower Guarantee.

What brands do you install

We service and replace most major brands – Navien, Noritz, Rinnai, Takagi, Rheem, AO Smith. We recommend models based on your home, water quality, and budget.

Do you service what you install

Absolutely. We provide annual descaling, maintenance, repairs, and priority support for our customers across Orange County.

Will my gas line need to be upsized

Sometimes. We measure gas demand for your appliances and confirm venting and combustion air. If an upgrade is needed, we handle it the right way so performance is never compromised.

We calculate flow rate and temperature rise based on your fixtures and usage patterns. The goal is simple – hot showers and laundry at the same time without dropouts.

Do you offer water treatment to protect my new unit

Yes. Hard water is common in Orange County. We can add a scale reduction filter or softener to extend the life of your heat exchanger and maintain efficiency.
