Frequently Asked Questions About Tankless Water Heater Installation in Johns Creek
Most gas tankless installations cost $3,000 to $6,500 including the unit, labor, venting and typical gas line upgrades. Electric units can be less, though panel upgrades can add $1,000 to $3,000.
Many manufacturers offer 10 to 15 year heat exchanger warranties and shorter coverage on parts. We also warranty our installation labor.
Tankless water heaters offer several key benefits: endless hot water on demand, real energy savings from heating water only when needed, a longer lifespan (often 20+ years) and a compact, space-saving design. They also lower the risk of tank leaks and the water damage that comes with them.
No, we firmly advise against DIY tankless water heater installation. These systems involve complex connections for gas, water and electricity, along with specific venting requirements. Improper installation can lead to safety hazards, void warranties and costly repairs. Always use a licensed professional.
In Georgia, plumbing and often gas or electrical permits are typically required for tankless water heater installation. HGR Plumbing handles all necessary permit applications and makes sure your installation passes all required inspections by local authorities.
A straight replacement takes four to six hours. Tank to tankless conversions with gas and venting changes usually take a full day.
Yes, tankless water heaters are very energy efficient in almost any climate. Around Johns Creek, sticky air means sweating cold-water pipes and toilet tanks are common, and that moisture can quietly damage subfloors if nobody notices. Since they only heat water on demand, they avoid the standby heat loss common with traditional tanks, which can be significant even in milder seasons.
A standard tankless water heater installation, replacing an existing tank, usually takes 4 to 8 hours. If extensive plumbing or gas line changes are required, it may take a full day. Our team works efficiently to restore your hot water as soon as possible.
