Want endless hot water and lower energy bills? A tankless water heater may be the upgrade your home needs. At Delta Plumbing, Repipe and Drains, we provide full tankless water heater installation, repair, and replacement services to help you enjoy hot water when you need it—without wasting energy when you don’t.



We work with gas and electric on-demand systems and help homeowners choose the right size and model for long-term comfort and efficiency.

What Is a Tankless Water Heater?


Unlike traditional tank units, a tankless water heater (also called on-demand) heats water instantly as it flows through the system—meaning no storage tank, no standby heat loss, and no running out of hot water.


Benefits of going tankless:

  • Endless hot water for showers, laundry, and more
  • Up to 30–50% energy savings over tank systems
  • Longer lifespan (typically 15–20 years)
  • Compact wall-mounted design saves space
  • Less risk of leaks or water damage


Tankless systems are ideal for modern families, remote bathrooms, or anyone tired of cold showers.


Our Tankless Services Include:


  • New system installation (gas or electric)
  • Upgrading from tank to tankless
  • Annual descaling and maintenance
  • Error code diagnosis and repair
  • Proper venting, gas sizing, and permits
  • Manufacturer-backed warranties on installations


Our licensed plumbers ensure your new system is installed to code and calibrated for your home’s demand, avoiding the undersizing issues many DIY setups face.


Is Tankless Right for My Home?


We get this question often—and it depends on your home’s size, water usage, and existing plumbing setup. That’s why we always offer a professional assessment first.

A tankless water heater is a great fit if you:


  • Want continuous hot water for multiple people or bathrooms
  • Want to reduce your energy use and utility bills
  • Have limited space for a bulky tank
  • Plan to stay in your home long-term and want a higher-efficiency upgrade


We’ll help you compare options and make the call that fits your needs and budget.

Section 1.10.33 of "de Finibus Bonorum et Malorum", written by Cicero in 45 BC "At vero eos et accusamus et iusto odio dignissimos ducimus qui blanditiis praesentium voluptatum deleniti atque corrupti quos dolores et quas molestias excepturi sint occaecati cupiditate non provident, similique sunt in culpa qui officia deserunt mollitia animi, id est laborum et dolorum fuga. Et harum quidem rerum facilis est et expedita distinctio. Nam libero tempore, cum soluta nobis est eligendi optio cumque nihil impedit quo minus id quod maxime placeat facere possimus, omnis voluptas assumenda est, omnis dolor repellendus. Temporibus autem quibusdam et aut officiis debitis aut rerum necessitatibus saepe eveniet ut et voluptates repudiandae sint et molestiae non recusandae. Itaque earum rerum hic tenetur a sapiente delectus, ut aut reiciendis voluptatibus maiores alias consequatur aut perferendis doloribus asperiores repellat." 1914 translation by H. Rackham "On the other hand, we denounce with righteous indignation and dislike men who are so beguiled and demoralized by the charms of pleasure of the moment, so blinded by desire, that they cannot foresee the pain and trouble that are bound to ensue; and equal blame belongs to those who fail in their duty through weakness of will, which is the same as saying through shrinking from toil and pain. These cases are perfectly simple and easy to distinguish. In a free hour, when our power of choice is untrammelled and when nothing prevents our being able to do what we like best, every pleasure is to be welcomed and every pain avoided. But in certain circumstances and owing to the claims of duty or the obligations of business it will frequently occur that pleasures have to be repudiated and annoyances accepted. The wise man therefore always holds in these matters to this principle of selection: he rejects pleasures to secure other greater pleasures, or else he endures pains to avoid worse pains."
