Tankless Water Heater Installation & Replacement

If you’ve ever run out of hot water halfway through laundry day or back-to-back showers, it might be time for an upgrade. Isaac installs high-efficiency tankless water heaters that heat water on demand without a bulky tank, waiting, and wasted energy.

Our team can replace your old tank-style system or install a brand-new tankless unit from scratch. We’ll walk you through your options, handle all plumbing and venting adjustments, and make sure your new water heater is properly sized for your home’s needs.

Benefits of Tankless Water Heaters

Switching to tankless offers several advantages that go beyond just comfort:

  • Endless hot water: Perfect for families or multi-bathroom homes.
  • Energy efficiency: Uses less fuel since it heats only what you use.
  • Lower utility bills: Efficient performance keeps monthly costs down.
  • Long lifespan: Most units last up to 20 years or more with proper care.
  • Smaller footprint: Frees up valuable space in basements and utility rooms.
  • Reduced leak risk: No large storage tank to burst or rust over time.

Tankless Water Heater Repair

A tankless water heater should deliver steady, reliable heat. If yours isn’t, it’s time to call Isaac.

Our technicians diagnose and repair all major tankless brands and models. Common issues include ignition or sensor failures, sediment buildup, gas supply problems, and heating element wear. And with our 24-hour emergency service, you won’t be stuck without hot water for long.

Tankless Water Heater Maintenance

Even the best systems need a little care to stay efficient. Annual maintenance helps prevent scale buildup, protects the heat exchanger, and extends your unit’s lifespan.

During your visit, an Isaac technician will:

  • Flush the system to remove mineral deposits
  • Inspect the venting, gas line, and safety components
  • Check flow rates and temperature calibration
  • Verify performance and look for signs of wear

Regular maintenance not only keeps your tankless system running like new, but it also helps preserve your manufacturer’s warranty.

Tankless Water Heater FAQs


Most tankless systems last around 20 years or longer with annual maintenance, nearly double the average lifespan of a storage tank unit.

Tankless systems use less energy because they heat water only when needed, reducing standby heat loss and lowering your monthly utility costs.

Once a year is ideal for most homes. If your water supply has a high mineral content, consider flushing every six months to prevent scale buildup.
