Common questions
What is the downside to tankless water heaters?
The initial investment for a Navien tankless water heater can be higher than that of a traditional tank unit. In some older North Carolina homes, upgrades to existing gas lines or electrical services may be required to meet the unit's operational demands. Furthermore, simultaneous use of multiple high-demand fixtures necessitates careful unit selection to avoid potential flow rate limitations.
Can you run two showers with a tankless water heater?
The ability of a Navien tankless water heater to supply hot water to two showers concurrently in North Carolina depends on the unit's Gallons Per Minute (GPM) rating and the flow rate of the individual showerheads. Appropriately sized units can effectively manage this demand, ensuring a consistent hot water supply. A professional assessment of your home's plumbing system is essential for determining adequate capacity.
How long do hot water heaters typically last?
Standard tank water heaters generally have a service life of 10 to 15 years. Navien tankless water heaters, with consistent professional maintenance, including periodic descaling, are designed for extended durability and can often operate efficiently for 20 years or more, providing a long-term solution for North Carolina homeowners.
