Old gas heater:
Rinnai REU-55CGL
New gas heater:
Macro MA-10FE
A homeowner at 26B Jalan Membina contacted Homeone Engineering after their Rinnai REU-55CGL Gas Water Heater HDB stopped producing hot water. Our licensed specialists conducted a thorough site inspection and found the following issues:
No Hot Water Output – The heater had completely failed and was no longer functioning.
Over 17 Years Old – The serial number confirmed the heater was far beyond its typical lifespan, making it unsafe and inefficient.
Rusty Fittings – The connected water and gas pipes fittings showed advanced rust and corrosion, creating reliability and safety concerns.
Corroded Safety Valves – The gas valve and water stop valve were hard to operate due to corrosion, posing operational risks.
With these findings, the old Rinnai HDB gas heater model was deemed beyond repair. The homeowner opted for a Macro MA-10FE Indoor Gas Water Heater HDB, a reliable and widely used replacement model in Singapore HDB flats.
All works were supervised out by Homeone ’s Licensed Gas Service Workers (LGSWs) in compliance with EMA safety standards, PUB regulations, and the Gas Supply Regulations of Singapore.

The Rinnai REU-55CGL Gas Water Heater HDB had exceeded its expected service lifespan of over 17 years. With complete failure, corroded piping, and discontinued market availability, keeping the unit in service was neither safe nor practical.
By upgrading to the Macro MA-10FE Indoor Macro HDB Gas Heater Model, the homeowner now benefits from:
✅ Reliable hot water supply
✅ Safe and efficient operation
✅ Installation in compliance with PUB and EMA standards
✅ Long-term peace of mind with warranty coverage

When an HDB gas water heater model reaches the end of its lifespan—especially with corrosion, valve issues, or discontinued parts—it’s critical to replace it promptly.
The replacement of the Rinnai REU-55CGL with a Macro MA-10FE Indoor Gas Water Heater HDB at 26B Jalan Membina ensured continued safe hot water supply, full compliance with Singapore’s regulations, and peace of mind for the homeowner.
