Fequently Asked Questions
You likely need repairs if your unit is displaying error codes on the digital panel, if the water temperature fluctuates wildly during a single shower, or if the system shuts off completely when multiple fixtures are running.
A high-quality gas tankless water heater can last up to twenty years, nearly double the lifespan of a traditional tank, provided it receives annual maintenance and routine descaling to protect the heat exchanger.
Retrofitting a home for a new tankless water heater typically takes a full day. The process requires mounting the unit, running new ventilation pipes to the exterior, and often upgrading the gas supply lines to handle the higher BTU demand.
This is often called a "cold water sandwich" and occurs when the unit detects a drop in water flow and briefly shuts off the burners. It can also be caused by a dirty flow sensor that fails to read the water demand accurately.
Your tankless water heater must be professionally flushed with a descaling solution once a year to remove calcium and mineral buildup. Homes with extremely hard water may require this service every six months to maintain system efficiency and validate the manufacturer's warranty.
