Upgrade to a Smarter, More Efficient Water Heating Solution

Embrace the Future with Tankless Boiler Systems

Leading the way in energy-efficient heating across Quincy, Greater Boston, and the South Shore

At Johnson Bros. Plumbing & Drain Cleaning, we’re revolutionizing home water heating with our cutting-edge tankless water heater systems. Our expert installations—featuring premium brands like Navien, Rinnai, and Viessmann—bring you endless hot water, optimized energy savings, and space-efficient designs. These systems eliminate the inefficiencies of traditional storage tanks, helping homeowners across Quincy, MA, reduce their utility bills and environmental impact.

Our team of licensed professionals ensures a smooth installation process tailored to your specific needs, making sure your tankless water heater delivers consistent, high-performance results for years to come.

Say goodbye to bulky storage tanks. Traditional water heaters can take up valuable floor space in your home, while tankless water heaters mount neatly on your wall. Whether you live in a small apartment or a larger family home, tankless water heaters offer a compact, space-saving solution that fits seamlessly into any layout.
Heat water only when you need it. Unlike traditional storage tanks that continuously heat and reheat water, tankless systems provide hot water on demand. This not only reduces energy waste but also ensures that you’re maximizing performance while lowering your monthly utility bills. Energy-efficient models from Navien, Rinnai, and Viessmann are designed to meet the highest industry standards, making them a smart choice for eco-conscious homeowners.
With lifespans of 20+ years and ENERGY STAR® certification, tankless water heaters are a long-term investment that pays off. Lower energy consumption means lower utility bills, and the durability of these systems reduces the need for frequent replacements. Plus, our professional maintenance services ensure your tankless water heater continues to operate at peak performance.

Nate was able to come and complete the project all in the same day. He installed a new vanity, sink in an old stubborn house. He beat his competitor by half the price! Highly recommended and reliable.

Nate was nothing short of exceptional from his initial response to completion of the project. I had an unexpected issue needing an immediate hot water tank replacement at a rental property. Not only did he do a great job but was empathetic, personable and professional throughout.

Would highly recommend - this is a great, honest, family-owned company. We had a cast iron toilet flange issue for a while. Nate and Jahz (our technician) came up with a creative solution to solve the problem - Jahz went to the store multiple times to try different pieces to see what worked. When there was a minor tweak needed after the installation, Jahz promptly scheduled another visit for the next day. Thank you Johnson Bros!
