🏢 CityGas Heater Replacement at Alex Residences, Alexandra (7 May 2024)
Why Alexandra residents choose gas heaters
If you live around Alexandra, many of the condominiums — including Ascentia Sky, Alex Residences, and The Metropolitan — were originally fitted with city gas-powered water heaters to supply multiple bathrooms. These wall-mounted systems are reliable and efficient, but after many years of use, older models often show signs of wear such as gas leak above 50ppm, heat exchanger corrosion and leaking water, burner rusty and choked, internal rust, or inconsistent ignition.
At Homeone, we specialise in EMA licensed gas heater replacement and testing for these condo systems. Every project includes gas leak inspection, Final pressure test for consumer’s internal pipes in residential premises at 450mm w.g. for 5 minutes. Ensuring your installation meets City Gas and PUB standards for continued safe use.
Every gas heater project in Alexandra is carried out with strict adherence to Singapore regulations:

ALEX RESIDENCES (CONDO) 🏢
Internal Water Leaking and Corroded
This project at Alex Residences involved replacing an older Gas water heater powered by City Gas that is almost reaching end of its lifespan. The old unit showed visible corrosion on its copper pipes and fittings, which could eventually lead to leaks if left unattended.
Our team installed a new Macro gas water heater and upgraded the connecting pipes with fresh fittings to ensure a secure, long-lasting setup.
ASCENTIA SKY (CONDO) 🏢
Gas Heater Replacement due to Motherboard Melted, Control Panel No Display
The Gas water heater powered by City Gas, which had been in service for about 11 years, had become unsafe to operate. The motherboard was partially melted, several cable connections were rusted, and the control panel had stopped displaying readings. These faults were signs of long-term heat and moisture damage within the unit and indicated that it had reached the end of its usable life.
Our team replaced the old system and completed the installation in full PUB compliance, including leak testing and final pressure checks to ensure safe operation before handover.
QUEENS PEAK (CONDO) 🏢
Motherboard Melted, Control Panel No Display
We replaced an old Gas water heater powered by City Gas at Queens Peak, a condominium in Alexandra that had already reached the end of its service life. The heater showed signs of rust and corrosion on the copper piping, and the fittings were starting to leak.
A new Macro gas heater was installed with new piping and proper sealing to ensure a safe, lasting setup. All work was completed according to PUB and City Gas safety requirements, including full leak and pressure testing before handover.
