Top Reasons Portola Hills Residents Choose Tankless Water Heaters

Intelligent heating, everyday comfort, and big savings over time

A tankless water heater isn’t just a comfort upgrade, it’s a smart, energy-saving investment. Instead of storing and constantly reheating water like a tank model, tankless water heaters work on demand for maximum efficiency.

Why so many homeowners are choosing to install or replace their old units with tankless systems.

  • Unlimited Hot Water – Perfect for large families, back-to-back showers, and busy households
  • Energy Efficiency – Save money by heating water only when needed
  • Space Saving – Compact design fits tight spaces and adds valuable storage room
  • Durable Construction – Lasts 20 years or more with proper care and maintenance
  • Better-Tasting Hot Water – Tankless systems eliminate stagnant water and mineral buildup
  • Eco-Friendly – Eco-friendly technology that’s better for your home and the environment

If your old water heater is leaking or inefficient, we can replace it with a modern tankless model designed for your household needs.

Looking for a regular tank water heater? Our team handles those, too.

Frequently Asked Questions

[su_spoiler title='Do you offer water treatment to protect my new unit' open='no' style='fancy']

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.

[/su_spoiler][su_spoiler title='Will my gas line need to be upsized' open='no' style='fancy']

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.

[/su_spoiler][su_spoiler title='How much does tankless replacement cost' open='no' style='fancy']

Price depends on brand, size, venting, gas line work, and water treatment. We give firm, written options before any work begins, and financing is available.

[/su_spoiler][su_spoiler title='What warranties do I get' open='no' style='fancy']

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

[/su_spoiler][su_spoiler title='How long does a replacement take' open='no' style='fancy']

Straight swaps can be completed in a few hours. Tank to tankless conversions often finish the same day, depending on venting path and gas line work.

[/su_spoiler][su_spoiler title='What brands do you install' open='no' style='fancy']

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.
