Frequently Asked Questions About Electric Tankless Water Heater Installation in Dunwoody
Point-of-use units typically cost $500 to $1,500 installed. Whole-home electric tankless installations often run $1,500 to $4,500, and panel upgrades can add $2,000 to $4,000.
Installing an electric tankless water heater is a complex job involving high-voltage electricity and plumbing, making it unsuitable for DIY. Incorrect installation can lead to electrical hazards, water damage and voided warranties. It's always best to hire a licensed and experienced plumber like HGR Plumbing for safe and proper installation.
In most areas, permits are usually required for electric tankless water heater installation, particularly due to the electrical work involved. Plumbing work in Georgia is licensed at the state level, so it pays to verify that whoever works on your home holds a current license. HGR Plumbing handles all necessary permit applications in Dunwoody and makes sure the installation passes all required inspections.
Water hardness varies from place to place. Private wells still serve a large share of rural Georgia homes, and iron, sediment, and low pH can shorten the life of pumps, tanks, and copper lines. Like any water heater, electric tankless units benefit from regular flushing to prevent mineral buildup, especially if your Dunwoody area has harder water. We can advise on maintenance and offer water softening solutions if needed.
Most electric tankless installations require plumbing and electrical permits. We handle permits and schedule inspections.
Most electric tankless water heaters come with a manufacturer's warranty, typically 5 to 10 years on the heat exchanger and 1 to 3 years on parts. HGR Plumbing also provides a labor warranty on our installation services. We will discuss specific warranty details for your chosen unit during your consultation.
Installation requires plumbing and high-amperage electrical work. Professional installation ensures safety and protects your warranty.
Most electric tankless water heater installations can be completed within a single day, typically 4 to 8 hours. However, if major electrical panel upgrades or extensive re-piping are required, the process may extend into a second day. We aim to minimize disruption and restore your hot water as soon as possible.
