Macro Gas Water Heater HDB Replacement to the Same Macro MA-10FE at Blk 22 Ghim Moh Link on 9 Jan 2025


A homeowner at an HDB flat contacted Homeone after experiencing repeated issues with their Gas Water Heater HDB, including water leakage from the internal tank and connecting pipes. With the heater in service for over a decade and showing clear signs of corrosion, the risks of continued use were significant. Our licensed gas service team carried out a thorough inspection to identify the extent of the faults and advised that a full replacement would be the safest and most reliable long-term solution.

Indoor Macro MA-10FE Gas Water Heater HDB 00

Before

Replaced Indoor Macro Gas Heater HDB at end of service life.

After

Replaced with Macro MA-10FE water heater and corroded sections of cold water copper piping with new piping. Utilised single-use fittings during the replacement to ensure optimal joint integrity. Reconnecting old fittings again risks erosion, particularly in high-speed water systems, and raises the chance of corrosion in water and gas piping. This increases the risk of water or gas leaks. Replaced the faulty cold water sensor as part of overall maintenance to ensure optimal functionality.

Site Findings of Gas Water Heater HDB

When the homeowner at Blk 22 Ghim Moh Link reported that their Gas Water Heater HDB unit was not producing any hot water, our licensed team from Homeone carried out a detailed site inspection.

The findings included:

  • No Hot Water & Beeping Error Codes – The old indoor Macro water heater displayed error codes with continuous beeping, a sign of system failure.

  • Corroded Heater Exterior – After more than 10 years of use, the unit was visibly corroded (as seen in the photo), indicating end-of-life deterioration.

  • Rusty Piping – The connected piping was heavily rusted, raising safety concerns and reducing reliability.

  • Hard-to-Operate Valves – Both the gas valve and water stop valves had become stiff and corroded, making them unsafe and difficult to use.

Conclusion

If your HDB gas heater model is over a decade old, showing signs of corrosion, leaks, or error codes, it’s a clear sign that the unit is due for replacement. Attempting to operate a corroded or failing heater not only risks system failure but also compromises household safety.

The safest solution is to replace the old unit with a reliable Macro MA-10FE Indoor Gas Water Heater HDB, installed and tested by licensed professionals. This ensures safe operation, compliance with Singapore’s strict regulations, and reliable hot water for your family.
