A tankless water heater heats water as it flows instead of storing it. It doesn't run out of hot water and takes up little space, but it costs more to install and has to be sized for your coldest incoming water and your biggest simultaneous use.
Is tankless right for your Charlotte home?
Why size a tankless heater for winter?
Incoming water is colder in winter, so the unit has to raise the temperature further. A unit sized in summer can feel undersized in January, with lukewarm showers when two fixtures run at once.
What does a gas tankless install need?
Often a larger gas line than a tank heater, dedicated venting, and a nearby electrical outlet. Those are the main reasons a conversion costs more than a tank swap.
Maintenance and common repairs
Most manufacturers call for periodic descaling. Common service calls are error codes from scale or a clogged inlet filter, ignition or flame-sensor faults, venting problems, and units that shut off when flow is too low. Charlotte's municipal water is soft, which helps, but descaling still matters. For tank heaters, see water heater repair in Charlotte.
