I think Bay Ridge Plumbing & Boiler Repair is a great company. From beginning to end everyone we encountered was extremely professional and courteous. They all took their time and did a great job answering our questions and explaining everything to us. Our first encounter was with Dave who spent the time with us and explained out options. The re-piping crew that came out - Lucio, Jose and Justin were amazing. The arrived a little earlier than their scheduled time and stayed until they completed everything. I was so impressed with their work and professionalism. The next person who came was Flaniel to "put our house back together" with the sheet rock repair. Just as the others, Flaniel was professional, very friendly and did an amazing job. If someone was to come into our house now, they would never know there were many holes in the sheetrock. If you are ever in the need to have the pipes replace in your house, Bay Ridge Plumbing & Boiler Repair should be your only phone call.

Tankless Water Heater Frequently Asked Questions

  • What is a tankless water heater?

    Instead of storing water, tankless water heaters use heating coils to heat water as it’s needed, which is why they’re often referred to as “on-demand water heaters.” When you turn on a tap or start an appliance like a dishwasher, the tankless unit detects the demand and immediately begins delivering hot water where and when you need it. This makes tankless water heaters much more energy-efficient than traditional tank units, which continuously heat water even when it’s not in use.

  • What are the benefits of a tankless water heater?

    Tankless water heaters offer several advantages over traditional tank units. One of the key benefits is an endless supply of hot water. You can run multiple showers, do laundry, and use the dishwasher at the same time, all while enjoying uninterrupted hot water.

    Another significant advantage is nearly instant hot water—no more waiting for several minutes for the water to warm up; your tap will deliver hot water in seconds.

    With a Rinnai tankless water heater, you’ll also save space, as it’s much smaller than a traditional tank, and reduce energy costs due to its superior efficiency.

    Additionally, tankless units typically have about twice the lifespan of tanked water heaters. Overall, a tankless water heater outperforms a traditional tank water heater in almost every aspect.

  • Why choose Rinnai® for your tankless water heater?

    Rinnai® is the market leading tankless water heater. Bay Ridge Plumbing & Boiler Repair exclusively installs Rinnai because we believe they are the best.

  • What size tankless water heater do I need?

    When selecting the right size tankless water heater, several factors come into play, such as the number of people in your home or office and the number of facilities (like bathrooms, washrooms, laundry rooms, or kitchens) the unit will support. To make this process easier, our team can help you choose the ideal Rinnai tankless water heater capacity for your needs.

  • How long does a Rinnai tankless water heater last?

    A Rinnai tankless water heater can last up to 20 years, with its actual lifespan depending on factors like water quality, usage, and regular maintenance. For comparison, a tankless water heater lasts roughly twice as long as a traditional tank water heater, offering better value over time.

  • What types of fuel do Rinnai Tankless Water Heaters use?

    Rinnai tankless water heaters run on natural gas or propane and feature an electronic ignition system.

  • Why does a tankless water heater cost more than a tank water heater?

    Traditional tank water heaters are the most common type in the US. These heaters use older, less efficient technology to gradually heat cold water stored at the bottom of a large tank, constantly keeping the water heated until you need it. In contrast, tankless water heaters heat water on demand using heating coils, eliminating the need for storage. Tankless units are more energy-efficient, take up less space, and offer advanced technology not typically found in tank-based systems.

  • Can a tankless water heater produce enough hot water for my home?

    Yes. No matter how large your home, we can configure a tankless system to meet your needs. Rinnai systems can meet the needs of every thing from a tiny house to a mansion. A Rinnai Tankless Water Heater solves the tank heater water inconsistency problem because hot water becomes delivered at a precise temperature to every fixture. Imagine providing unlimited hot water to your home.

  • Can I change the hot water temperature on my Rinnai?

    Yes. Rinnai tankless units can be controlled on the unit or by using a wifi mobile application.

  • Are there tax credits available if I purchase a Rinnai tankless water heater?

    Yes, there are Federal Tax Credits available. If you select a tankless gas water heater, hybrid gas water heater, or natural gas tankless water heater with an energy factor of at least 0.82 or a thermal efficiency of 90% or higher, you may qualify for these tax credits.

  • Why choose Bay Ridge Plumbing & Boiler Repair?

    Bay Ridge Plumbing & Boiler Repair has the highest level of Rinnai dealer status and receives training at the Rinnai Headquarters in Peachtree City, GA. We provide quality service at a fair price.

  • Do you offer tankless water heater maintenance and repair?

    Yes! In addition to our tankless water heater installation and upgrades, we offer maintenance and repair services. One of the many benefits of a tankless water heater is that components can be easily exchanged, if needed, versus replacing the entire system.
