Emergency Tankless Replacement in Atlanta, GA
A tankless heater that leaks from the heat exchanger or refuses to ignite can leave you with no hot water at all. We offer same-day emergency replacement for common models and can usually get a unit installed the day you call.

Electric Tankless Water Heater Replacement in Atlanta, GA
For properties without natural gas access or those looking for an all-electric solution, electric tankless water heaters are a viable choice. HGR Plumbing offers electric tankless water heater replacement services in Atlanta, GA. This often involves careful assessment of your home's electrical panel capacity, as these units require substantial amperage. We make sure your new electric tankless unit is installed safely and correctly, providing on-demand hot water without the need for gas lines.
Exterior Mount Tankless Units in Atlanta, GA
Many homes have tankless heaters mounted on an exterior wall with no venting at all, since the unit exhausts directly outside. These units face sun, rain and temperature swings, which can wear out plastic covers and wiring over time. Before a cold night, disconnecting hoses, covering hose bibs, and letting a faucet drip are usually enough to prevent a burst line. When we replace them, we check the pipe cover, freeze protection settings and the electrical connection. We can add a protective pipe cover kit to shield the water and gas lines. Exterior models are often the easiest swap when the gas line is already sized correctly.
Rinnai Tankless Water Heater Replacement in Atlanta
Rinnai is a leading brand in the tankless water heater market, known for its quality and innovation. If your Rinnai unit is aging or acting up, HGR Plumbing provides expert Rinnai tankless water heater replacement in Atlanta. We make sure your new Rinnai unit is installed correctly, extending its efficiency and lifespan. Our technicians are familiar with the installation requirements and venting options for Rinnai models, so the upgrade goes smoothly.

Gas Tankless Water Heater Replacement in Atlanta
Many homes in Atlanta rely on natural gas for water heating, and gas tankless units are a highly efficient option.

For homeowners in Atlanta, upgrading to a tankless water heater offers significant benefits like endless hot water and reduced energy use.

Tank to Tankless Conversions in Atlanta, GA
Converting from a 40 or 50 gallon tank to tankless frees up floor space and ends standby heat loss in a garage or closet. The catch is that tankless units often need a larger gas line, often three quarter inch or bigger, plus new venting. We check your meter size and pipe run before quoting so there are no surprises mid-job. We also cap or reroute the old flue and seal the roof penetration if it is no longer used. Plan for a conversion to take a full day.
