Are Two Small Tankless Water Heaters Better Than One Big One?

- Separate control allows for more precise hot water temperature control.

- Multiple units can be installed closer to different hot water sources, reducing heat loss.

- Can provide redundancy, with one unit serving as a backup in case the other fails.

Cons:

- Two units can potentially result in higher electricity bills compared to a single large one, due to increased standby losses and energy consumption.

- Initial cost may be higher.

- Requires more space for installation.

- Maintenance of multiple units may be inconvenient and costly.
