Tankless Water Heater Services

Enjoy endless hot water and lower energy bills. We specialize in tankless water heater repair and installation for homes in Los Angeles, Santa Barbara, and Ventura Counties.

Tankless Water Heater Installation & Repair Across Southern California

Imagine never running out of hot water again, even when running the shower, dishwasher, and washing machine at the same time. That is the primary benefit of a modern tankless water heater. At Drain Charmer Plumbing & Rooter Inc., we are the local experts in the installation, repair, and maintenance of these high-efficiency, on-demand water heating systems.

Unlike a bulky traditional water heater that constantly heats a large tank of water, a tankless unit heats water the instant you need it. This on-demand technology is far more energy-efficient, saving you money on your utility bills. It also provides an endless supply of hot water and has a much smaller physical footprint, freeing up valuable space in your home.

Our Full Tankless Water Heater Services

We handle every aspect of tankless water heater ownership to ensure you get the best performance and lifespan from your unit. Our services include:

Expert Installation & Replacement: We help you select the correctly sized unit for your home’s needs and provide a professional, code-compliant installation.
Tankless Water Heater Repair: Our technicians are trained to diagnose and fix all common issues, from error codes and ignition failures to inconsistent heating.
Annual Maintenance & Descaling: We perform the essential annual flushing needed to remove mineral buildup (scale), which is critical for maintaining efficiency and preventing damage.

While tankless water heaters are incredibly reliable, they do require professional maintenance to perform at their best, especially in areas with hard water. The annual descaling and flushing we provide is the most important step you can take to protect your investment and ensure your unit operates efficiently for its entire 20+ year lifespan.

Whether you are ready to upgrade to the energy efficiency and endless hot water of a tankless system or your current unit needs professional repair or maintenance, our team is ready to help.

Andrew at Drain Charmmer and Rooter was super helpful, timely and attentive helping solve my tankless water heater issues. No hot water at the home front is an issue and resolving it quickly is three thumbs up. Many thanks!

Jimmie Culver

Drain Charmer and technicians are top notch. Ramon was able to fix my water heater in 5 minutes. Consider me a customer for life! Drain Charmer and Andrew replaced my water heater a few weeks ago and I couldn't be more pleased with the professionalism the entire crew displayed. Not only did they save me money but did the job 24 hours after I first called them. They truly are a 5 star company!

Drain Charmer did an excellent job replumbing our duplex that we are preparing to sell He and his team are very professional and great to work with. They reacted quickly to our urgent needs, provided an estimate same day, showed up on time and worked around the clock to complete the work fast. We are very impressed. Thank you Andrew and Jesse. Fun people to talk to.

A few days ago Andrew replaced my water heater the same day I called to announce the leak. The next day I texted him with questions about how to maintain the heater so it lasts longer. He spent 2 hours texting back and forth with me explaining how to do the yearly flush-out of both my units. I didn’t know how to do anything so it took sending photos in which Andrew patiently circled the knobs I needed to find and explained exactly how to do it. He is the best plumber I’ve found. I’ve used him for many jobs in the past and will continue to call on Andrew for my plumbing problems.

We had a weekend plumbing leak and the crew at Drain Charmer were so helpful, caring, and truly professional in fixing our issue. They went way beyond good service and we wouldn’t hesitate to call them with any future plumbing needs. We couldn’t be more pleased.

Wiktoria Marroquin

We had a plumbing emergency early on a Sunday morning, and while every other company told us we’d have to wait until the next day, Andrew and his team came through when we needed them most. They arrived within an hour! The customer service was outstanding from the start. Our technician, Jesse, was prompt, called ahead with his ETA, and resolved the issue quickly and professionally. Truly top-notch service — highly recommend them to anyone in need of fast, reliable, and friendly plumbing help.
