One power outage led to the same major plumbing failure across an entire neighborhood in Marietta, GA. When freezing weather cut electricity to the homes, the outdoor tankless water heaters lost their cold-weather protection. Justin Davis estimates that about 100 units froze and burst.
Davis & Sons Plumbing coordinated replacements throughout the neighborhood. Because so many homeowners needed the same service, the team also offered a volume price break that lowered the cost for each participating neighbor.
| Location | Marietta, GA |
| Property type | Residential neighborhood |
| Neighborhood age | About three years old |
| Project size | Approximately 100 homes |
| Equipment | Outdoor tankless water heaters |
| Cause | A weather-related power outage during freezing temperatures |
| Service | Tankless water heater replacement |
| Outcome | Coordinated replacements with a volume price break for residents |
Every home in the three-year-old neighborhood had an outdoor tankless water heater. The units could operate during freezing weather as long as they had electricity. When the neighborhood lost power, that protection stopped working.
Water left inside the equipment froze and expanded. The heaters then burst, leaving residents across the neighborhood facing the same unexpected replacement.
The scale made this more than a typical water heater call. Justin described the development as a cluster of about 100 homes in Marietta, with failed water heaters throughout the neighborhood. Residents needed a coordinated response from a plumbing team that understood the shared cause of the damage.
Davis & Sons Plumbing connected the failures to the winter power outage and organized the work across the neighborhood. Instead of treating each home as a completely separate project, the team coordinated the replacements as one large response.
That approach made the work more efficient and created a direct benefit for residents. With many similar replacements in one area, Davis & Sons Plumbing offered homeowners a volume price break. Each neighbor saved money while receiving professional tankless water heater replacement.
The team moved through the neighborhood replacing the outdoor tankless water heaters that had frozen and burst. Each home needed a new unit after the power loss left the existing equipment exposed to freezing temperatures.
Tankless water heater replacement requires more than swapping one appliance for another. The new equipment must be installed to code and connected correctly to the home’s water, electrical, gas, and venting systems when those connections apply. The system also needs to be tested before the work is complete.
“Because we were doing so many, we were able to offer them a price break and save money for every one of the neighbors.”

Outdoor tankless water heaters often rely on electricity to protect their internal components from freezing. A unit may be designed for cold weather, but a winter power outage can stop that protection. Water trapped inside can then freeze, expand, and damage the equipment.
A freeze-damaged water heater should be inspected by a licensed plumber. The damage may involve water, electrical, gas, or venting connections, and it may not be safe or practical to repair the unit. A professional can assess the damage and explain whether repair or replacement is the right choice.
This project also shows the value of a coordinated response. When many homes experience the same failure, organized scheduling can help the work move more efficiently. In this case, the project volume also allowed Davis & Sons Plumbing to lower the price for residents.

How long does a tankless water heater replacement take?
Most standard tankless installations can be completed in one day. Gas-line, venting, electrical, code, or access requirements may add time, and a large coordinated project needs its own schedule.
How much does it cost to replace a tankless water heater after freeze damage?
The price depends on the replacement unit, fuel type, installation access, and whether the home needs gas-line, venting, electrical, or code upgrades. An inspection and itemized quote provide a more reliable answer than a general price range.
Do I need a permit to replace a tankless water heater in Georgia?
Permit and inspection rules vary by city and county, but many Georgia jurisdictions require them for water heater replacements. Ask the licensed plumber to confirm the local requirements and whether permitting is included in the project scope.
Does homeowners insurance cover a tankless water heater damaged by freezing?
Coverage depends on the policy and the cause of the damage. Some policies may cover sudden freeze damage or the resulting water damage, while excluding wear, poor maintenance, or other conditions, so homeowners should document the damage and contact their insurer.
Should I replace the frozen unit with the same tankless water heater model?
Not always. A plumber should confirm the home’s hot-water demand, fuel supply, electrical capacity, venting, and available space before recommending a model. Replacement is also a good time to correct an undersized unit or installation issue.
Freeze damage is not always visible from the outside. Davis & Sons Plumbing can inspect the unit, explain the options, and provide a clear quote for homeowners in Marietta and across the surrounding area. .
