If you're tired of running out of hot water during morning showers or dealing with a bulky water heater tank taking up valuable space, a tankless water heater may be the solution you need. These systems heat water on demand rather than storing it, providing continuous hot water whenever you turn on the tap. At bluefrog Plumbing + Drain in Marietta, our licensed, insured plumbers handle everything from tankless water heater installation to repairs and ongoing maintenance, giving your home or business reliable hot water when you need it.
Why Go Tankless?
Tankless water heaters operate differently from traditional tank systems by heating water only when you need it. Instead of storing 40 to 80 gallons of hot water, these systems heat water instantly as it flows through the unit. When you turn on a hot water tap, cold water passes through a gas burner or electric element and is quickly brought to your desired temperature. This on-demand setup means you won’t run out of hot water, even during back-to-back showers or while running multiple appliances at once.
In addition to continuous hot water, tankless systems offer practical benefits for Marietta homeowners. Their compact, wall-mounted design saves space compared to bulky storage tanks, making them ideal for basements, utility rooms, or closets. Many homeowners also experience improved energy efficiency since the system only runs when needed, helping reduce the standby energy loss common with traditional tank water heaters.

Tankless Water Heater Services
The Right Solution. The First Time.
Tankless Water Heater Repair
When your tankless system isn’t performing as expected, our technicians quickly diagnose and repair the issue. We address common problems like inconsistent temperatures, ignition failures, error codes, mineral buildup, and reduced output. Marietta’s moderately hard water can accelerate scale in heat exchangers, so we use manufacturer-specific tools to pinpoint the cause and restore reliable operation.
Tankless Water Heater Installation & Replacement
Proper installation starts with accurate sizing based on your home’s peak demand and simultaneous fixture use. Our team evaluates flow rate needs and temperature rise for Marietta’s climate, then handles gas line sizing, venting, electrical connections, and water line setup. For replacements, we also assess whether your existing gas line can support a tankless system.
Tankless Water Heater Maintenance
Routine maintenance helps your system run efficiently and last longer. Our service includes descaling to remove mineral buildup, inspecting filters and screens, testing sensors and controls, and checking venting. Annual maintenance is recommended in Marietta to prevent issues and ensure consistent hot water performance.
