A homeowner at 10 Pine Close HDB contacted Homeone after experiencing persistent issues with their Joven JH25 storage water heater. The unit was no longer heating reliably and was showing signs of internal wear. Additionally, the homeowner was concerned about the safety of the ageing system. They requested a new 25L model with improved reliability, and we recommended the Ariston PRO RS J 25—a modern, efficient alternative.
Upon closer inspection, our technician identified that this was more than just a standard Joven Water Heater Replacement. Several fittings and pipes connected to the old heater were visibly corroded and rusty, posing long-term risks of leakage and contamination. The original installation also lacked a check valve (to prevent water backflow) and had no drainpipe to properly discharge water from the pressure relief valve—both of which are non-compliant under PUB regulations.
