The Bosch JSRZ5-T PG is a discontinued model, which means replacement parts are no longer reliably available in Singapore. Even if the unit could be repaired today, the next fault would likely leave the homeowner without hot water for an extended period while parts are sourced — if they can be sourced at all. Combined with the heater being at the end of its service life, continued repair was neither practical nor economical.
Replacing the unit with the Macro MA-8NFL restored a dependable hot water supply, brought the installation up to current safety standards, and gave the homeowner a serviceable system backed by warranty and locally available parts.
