Instant Water Heater Replaced With Rheem RCY 15 Water Heater at 3B Upper Boon Keng Road HDB on 1 Feb 2024

As a recurring customer, the decision for a water heater replacement stems from the recent incident at the customer's uncle's house, where their instant water heater, having reached the end of its lifespan, experienced a malfunction resulting in a burnout. Prioritizing safety, the customer is opting for a storage water heater. They recognize the safety advantages, as storage heaters can mitigate the risk of electrocution by utilising bonding to safely discharge electricity in the event of a faulty earth MCB. This informed choice aligns with the customer's commitment to a secure and reliable home environment.
