Tankless Water Heater Installation & Service in Atlanta, GA

Tired of running out of hot water during back-to-back showers? 

Tired of running out of hot water during back-to-back showers? A tankless water heater might be the perfect solution for your Atlanta home. At Henson Mechanical, we specialize in installing, repairing, and maintaining high-efficiency tankless water heaters that provide unlimited hot water on demand while significantly reducing your energy bills.

What Is a Tankless Water Heater?

Unlike traditional tank water heaters that constantly heat and store 40-50 gallons of water, tankless systems—also called on-demand water heaters—heat water instantly as it flows through the unit. This means you only heat water when you actually need it, making tankless systems far more energy-efficient. Tankless water heaters have become increasingly popular among Atlanta homeowners seeking to lower utility costs while enjoying superior performance and reliability.

Why Atlanta Homeowners Choose Tankless Systems

Energy Efficiency & Lower Bills: Tankless water heaters use 24-34% less energy than traditional tank models, according to the U.S. Department of Energy. In Georgia's warm climate, this efficiency advantage is even more pronounced since your unit works less to reach desired temperatures. Many homeowners see noticeable reductions in monthly energy bills within the first few months of installation.

Unlimited Hot Water: Say goodbye to the frustration of running out of hot water. Tankless systems provide continuous hot water for multiple simultaneous uses—multiple showers, laundry, and dishwashing all at once without compromising water temperature.

Space-Saving Design: Tankless units are compact wall-mounted systems that take up a fraction of the space required by traditional 50-gallon tanks. This is especially valuable in smaller Atlanta homes or apartments where space is at a premium.

Longer Lifespan: Most tankless water heaters last 20+ years with proper maintenance, compared to 8-12 years for traditional tanks. This longevity translates to better long-term value and fewer replacement cycles.

Environmental Benefits: By consuming less energy, tankless systems reduce your home's carbon footprint and qualify for various federal tax credits and rebates.

Tankless Water Heater Installation Process

When you choose Henson Mechanical for your tankless water heater installation, you can expect a professional, hassle-free process:

1. In-Home Assessment: Our certified technicians evaluate your home's hot water demand, existing plumbing configuration, and gas or electrical supply. We'll determine the right size and capacity to meet your family's needs.

2. System Selection: We install all major brands including Rinnai, Navien, EcoSmart, and Takagi. Our team helps you select the system that offers the best balance of performance, efficiency, and budget for your specific situation.

3. Professional Installation: Our licensed plumbers handle all aspects of installation, including proper venting (for gas models), electrical connections, water line modifications, and integration with your existing plumbing system.

4. Thorough Testing: After installation, we test all connections, water temperature, and gas/electric supply to ensure everything operates at peak efficiency and safety.

5. Customer Training: We walk you through operation, maintenance requirements, and how to get the most from your new system.

Types of Tankless Water Heaters

Gas Tankless Water Heaters: These models use natural gas or propane to instantly heat water and are ideal for homes with existing gas lines. They offer higher flow rates and are often more cost-effective for larger families.

Electric Tankless Water Heaters: Perfect for homes without gas service, electric models require proper electrical infrastructure but offer excellent efficiency and require less maintenance than gas units.

Hybrid Systems: Some homeowners opt for hybrid solutions combining tankless technology with traditional tanks for maximum efficiency and reliability.

Cost Savings & Return on Investment

While tankless water heaters have higher upfront costs than traditional tanks ($800-$3,500+ depending on the model), the long-term savings are substantial:

  • Average energy savings of 24-34% annually
  • Reduced hot water loss through long pipes
  • Fewer emergency repairs and replacements
  • Potential tax credits and rebates (up to $300+ federal)
  • Georgia offers various state-level efficiency incentives

For many Atlanta families, the system pays for itself within 5-8 years through energy bill reductions alone.

Maintenance & Care

To keep your tankless water heater running optimally for 20+ years:

Annual Professional Maintenance: We recommend annual inspections and descaling (especially in areas with hard water) to prevent mineral buildup that reduces efficiency.

Regular Filter Cleaning: Monthly filter checks and periodic replacement maintain optimal water flow and protect internal components.

Professional Repairs: If you notice issues like inconsistent water temperature, reduced flow, or strange sounds, contact us immediately. Early intervention prevents costly repairs.

Tankless Water Heater Repair Services

Even the most reliable tankless systems occasionally need professional attention. Common issues include:

  • Temperature fluctuations or inconsistent hot water
  • Low water pressure or flow rate
  • Error codes or warning lights
  • Mineral buildup from hard water
  • Gas ignition problems

Henson Mechanical provides rapid response for tankless water heater repairs. Our certified technicians diagnose issues quickly and provide transparent cost estimates before proceeding with repairs.

Thank you!!! Justin was very professional and courteous. He took his time explaining the deficiencies with my AC system and what he would be doing to repair it. He broke down costs(which are very reasonable), and gave me pointers on keeping my system healthy with the right maintenance. Thank you, Justin. I’d also like to leave a review for the sweet lady that took my initial call, I believe her name was Tanya(but don’t quote me). She was also very professional and sent Justin out right away. This was after 5pm as well, so the service no matter the time of day is on point! Henson, you guys have a customer for life! Many Thanks!

We have a three year-old and Work crazy hours and are never home. We’ve been having issues with our AC unit for about two weeks now on and off. One day it works, the next day it doesn’t. Two days ago it finally stopped working. I tried everything I could think of, because we all know googling can sometimes solve the problem. I was referred to them from a larger company who was unable to make it out the same night. It was about 8:30 PM and the operator told me I would be added to the list for the night and they could fit me in. I was expecting a call around two or 3 AM because I knew there were a few clients ahead of me. Instead, Jake called me around 9:45 pm and said he was about 15 minutes away. He was at my house until midnight fixing my problem. Turns out it was a pretty bad clog. Cleaned out the entire drain system, all the piping, and replace the condenser box for me! I would recommend them to anybody! Fast service, affordable, and the fact that they were at my house until midnight just so I could sleep comfortably, meant the world to me! I signed up for their yearly maintenance plan and I’m looking forward to working with them for many years to come!

Our technicians name was Aaron. Not sure if that's the correct spelling. I didn't see his name on the list of technicians to choose for my review. Either way, he was absolutely the best that I could have hoped for. Professional, thorough and all around pleasant. He had the AC back on and working better than it did before it broke. I hope this company trains all their technicians as well as him. Thank you very much Aaron for your help today. The Hamiltons
