Top Reasons Lake Forest Residents Choose Tankless Water Heaters

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. 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.

  • Endless Hot Water – Enjoy nonstop hot water for families, long showers, and daily routines
  • Lower Energy Bills – Reduce monthly costs with on-demand heating and improved energy efficiency

  • Eco-Friendly – Go green with a system that saves energy and reduces waste

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

If a standard tank-style water heater is what you need, we’ve got you covered.

Frequently Asked Questions

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.

What size tankless do I need

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 replace tank models with tankless

Yes. We convert from tank to tankless, upgrade gas lines if required, add proper venting, and handle permits and haul away.

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.

Do you service what you install

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

How long does a replacement take

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.
