Nothing’s worse than running out of hot water when you need it most – especially in your own home. Old tank heaters lose efficiency over time, leak easily, and waste energy month after month. This is the best time to switch to a modern tankless water heater and enjoy instant hot water.

At Elder & Young Plumbing, we specialize in tankless water heater installation and replacement in Seal Beach, California. Every installation is handled by licensed experts using best-in-class products from brands you can trust, such as Rinnai, Navien, and Noritz.

Unlike old tank models, tankless systems only heat water as you use it, providing unlimited hot water while cutting energy bills by up to 30%. They save space, reduce maintenance needs, and outlast traditional tank-style heaters by years.

From replacements to new installations, our team handles everything quickly, cleanly, and with guaranteed results.

Why Homeowners in Seal Beach Are Switching to Tankless Water Heaters

Intelligent heating, everyday comfort, and big savings over time

Tankless water heaters are more than a luxury, they’re a smart investment. 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.

  • 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
  • Space Saving – Tankless units take up a fraction of the space of old tank water heaters
  • Long Lifespan – Lasts 20 years or more with proper care and maintenance
  • Healthier Water Quality – Tankless systems eliminate stagnant water and mineral buildup
  • Green Performance – Lower energy use means a smaller carbon footprint and cleaner operation

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

We also offer expert installation for conventional tank water heaters.

Understand when to make the switch and what you’ll gain from a modern system

Here are the common signs you might need a new tankless or upgraded water heater.

  • Uneven or unreliable water temperature from room to room
  • Signs of moisture or corrosion at the base of your current heater
  • Your traditional tank water heater is over a decade old
  • Slow hot water delivery or limited capacity
  • Your energy costs are creeping higher each month
  • Planning a remodel or new addition that increases hot water demand
  • You want to replace your old tank model with an energy-saving tankless system

Our installation experts will inspect your plumbing, gas, and venting systems to ensure a safe and code-compliant installation.

We’ll guide you in selecting the perfect system to match your home’s size and demand.

After installation, we test every connection, calibrate the unit, and show you how to operate it for optimal performance.

From now on, you’ll have consistent hot water whenever you need it, with zero stress or wasted energy.

More 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.

How much does tankless replacement cost

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.

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.

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 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.

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.

Our Hot Water Guarantee

Your tankless water heater will be installed or replaced to the highest standard, tested for perfect operation, and guaranteed to function properly. If your new system fails due to our workmanship, we will return promptly, fix the issue, and cover all labor and materials at our expense during our workmanship warranty period. No cold showers, no hidden costs - just reliable, efficient hot water you can trust.
