Tronic6000C_OnGRAY_r1For whole-house or commercial building hot water on demand, Bosch Thermotechnology offers its wall-mountable Tronic 5000C and 6000C electric water heaters in kW input models WH17 (Tronic 6000C), WH27 (Tronic 6000C) and WH36 (Tronic 5000C).

These compact and lightweight units deliver 97% thermal efficiency with minimal standby loss and have modulating elements that help ensure a constant GPM output temperature for hot water comfort. They also come with a filter screen on the units’ inlet to provide enhanced scale resistance buildup over time.

Tronic C models require hard wiring through double-pole breakers in the breaker box and require varying amperage service (WH17 80 amps –WH27 120 amps – WH36 180 amps of electricity).

For colder climate areas in North America where the average ground water temperature is less than 60°F, the Tronic 6000C WH17 is recommended for point-of-use applications only. Tronic 6000C WH27 and Tronic 5000C WH36 models may be suitable for the whole house use.

All three Tronic 5000C and 6000C models come with a 5-year limited warranty on the heating modules and a 2-year limited warranty on other component parts.
