Electric Tankless Water Heater Upgrades in Marietta, GA
Upgrading from a traditional tank water heater to an electric tankless model is a popular choice for Georgia residents looking for efficiency.

Electrical Panel Review and Upgrades in Marietta
Electric tankless water heaters can require a large amount of amperage depending on size. We review your panel capacity before installation. If your panel cannot support the unit, we coordinate with a licensed electrician for an upgrade. Proper wiring prevents tripped breakers and overheating. Planning ahead avoids costly surprises.
Whole-Home Electric Tankless Installation in Marietta
Whole-home electric tankless units can supply multiple fixtures at once when properly sized. Models like the Stiebel Eltron Tempra and Rheem RTEX often require multiple dedicated 240 volt circuits. We size the unit based on your peak flow and temperature rise. Attic and crawlspace temperatures climb quickly in summer, which speeds up wear on supply lines, drain pans, and any plastic piping run through those spaces. We install isolation valves for simple descaling.
Electric Tankless Water Heater Sizing and Selection in Marietta
Choosing the right electric tankless water heater size is essential for performance. In Marietta, factors like groundwater temperature and your household's simultaneous hot water usage determine the right GPM (gallons per minute) output required. HGR Plumbing provides expert consultation to help you select a unit that perfectly matches your demand, preventing cold showers and supporting efficiency. We consider your home's plumbing layout and electrical panel capacity to recommend the best model.
Whole-Home Electric Tankless Systems in Marietta, GA
For complete hot water coverage throughout your Marietta, GA home, a whole-home electric tankless system is an excellent choice. We size the unit appropriately based on your fixture count and simultaneous hot water usage, providing consistent temperatures at every tap. This typically involves a single, larger unit or a series of smaller point-of-use heaters for optimal performance.
Commercial Electric Tankless Water Heater Installation in Marietta
Businesses in Marietta can also benefit from the efficiency and space-saving advantages of electric tankless water heaters.

Electric Tankless for Guest Suites and Additions in Marietta, GA
Guest houses, guest suites and home additions often sit far from the main water heater. Running long hot water lines wastes water and energy.
