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.

Robin and Raquel in office are great! We want to give a shout out to Steve and Jake too! We love and appreciate y’all!

Steve, the owner, was fantastic at explaining in detail the system, pricing, and overall process. Extremely thorough, and I had no questions in the end that this was the right company. No pressure to buy, no sales pitch, and I didnt feel uncomfortable as a woman that I was being pressured or scammed like I did with Casteel, who came to give a quote earlier this week. Henson's pricing was unbeatable for a bigger system, duct work replacement/size upgrading, install, and warranty. Thousands less than Casteel was "discounting", and I feel good putting money into a family business rather than a million dollar conglomerate with sales people literally thrusting their hands in my face for a deal that "when I leave the deal goes with me". I paid on the spot with Henson, knowing this was the best deal, an honest company, and ensuring a family business carries on. I would absolutely recommend them to anyone for repair, replacement, or even just a quote.

John and I were very happy with the service. Caleb helped with three properties and was extremely patient with our tenants. Very polite, knowledgeable, and accommodating to our schedule. He was able to handle four units, including a diagnostic and putting in a replacement part with a...

I got lucky to have Jake come out to service my HVAC. He did a fantastic and thorough job inspecting the equipment. He explained everything in detail and a was a great person overall to interact with. Highly recommend this company and Jake. Update: Two days later Nick and a colleague came to install a furnace for me after a crack was found in the initial inspection. They did an amazing job with the install. They would not leave without making sure I was satisfied. Highly recommend!!

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.
