Bosch High Temp Kit #7736500074

The Bosch High Temp Kit (product reference 7736500074) is an optional accessory for Bosch Therm gas tankless water heaters, intended to enable higher outlet temperatures for commercial and high‑temperature domestic applications. When installed on compatible Therm models, the high‑temperature kit permits outlet water up to 180°F, extending Therm series use for process, hydronic, and other elevated‑temperature needs. I was unable to locate part number 7736500074 in Bosch North America product listings; this description is based on Bosch Therm series documentation and the High Temperature Kit installation manual.
