Compatibility with
other gas heater brands
Paloma > Rinnai
For Rinnai, you can choose from the top-of-the-line Rinnai REU-2008W-RS or the more affordable REU-2024WP-RS.
Paloma > Macro
The Macro MA-20WOD offers exceptional value, featuring built-in Wi-Fi for mobile app control.
Paloma > Ferroli
For European brands such as Ferroli, the GS 20 OE TG(I) is highly competitive in pricing, with a new Wi-Fi model launched in 2024.
Error Codes
The most common issues include C2 – 11: No ignition, typically caused by insufficient gas supply or a faulty PCB; Code A1 – 61: Fan blower motor failure or a faulty PCB; and Code E1 – 51: Gas inlet solenoid valve fault or a faulty PCB.
Currently the Printed Circuit Board (PCB) for MC-95 and MC-117 are both discontinued and will not be available in the future. Additionally, carbon monoxide emissions from incomplete combustion pose irreparable risks. If you suspect a gas leak, please contact us for a test.
Compliance & Safety
All gas work in Singapore must be tested and signed off by an EMA Licensed Gas Service Worker before handing to a consumer with a certificate. The metal pipes to the heater requires equipotential bonding as required by EMA and plumber works to the heater to carried out or supervised by a PUB Licensed Plumber. All gas heater works by Homeone will comply with authorities such as EMA Gas, PUB and EMA Electric.

Paloma Gas Heater Installation Guide – Steps
Replacement with Stainless Steel: All removed sections are replaced with stainless steel pipes and fittings, along with a new stop valve, for enhanced durability and longevity.
Removal of Old Water Pipes: Sections of old hot, cold, and recirculating water pipes are removed completely to ensure a clean and secure installation.
No Reuse of Old Components: Old components, including fittings, are not reused. Brand-new parts are installed to maintain optimal safety and performance.
Preventing Material Fatigue: Old fittings can experience material fatigue due to repeated loosening and tightening, which could lead to ruptures over time. These are replaced as part of our standard installation procedure.
Replacement of Key Gas Pipe Fittings:Essential gas pipe fittings, such as unions (remove only) and gas valves, are replaced as they often develop rust or misalignment after the dismantling of the old heater.
Ensuring Airtight Connections: Rust and wear on old unions and gas valves compromise airtightness, particularly after repeated dismantling and tightening. Brand-new components are used to guarantee secure and leak-free connections.
Preventing Gas Leaks:Old gas pipe fittings are one of the most common causes of gas leaks. These are replaced as part of the installation process to ensure safety.
Copper Pipe Replacement:
A section of the gas pipe is replaced with copper piping compliant with Table Y of BS EN 1057, ensuring adherence to recognised safety standards.
Gas Work Supervised by Fully Licensed Professionals:All work is carried out or supervised by a Fully Licensed Gas Service Worker (LGSW) certified by the Energy Market Authority (EMA). Individuals with a Restricted Licence are not permitted to perform.
Leak Testing in Compliance with SS608: The installation undergoes rigorous leak testing in accordance with the Singapore Code of Practice (SS608) to ensure compliance and safety.
Certification and Handover:The system is certified as leak-free before a certificate is issued to the customer, ensuring safe and reliable operation of the gas heater.
Plumbing Work Supervised by PUB Licensed Plumber:All plumbing works are carried out or supervised by a PUB Licensed Plumber in compliance with the relevant codes of practice to ensure proper and safe installation.

What to do when
you see an error code?
Call a certified professional NOT a handyman
Handyman does not have the training to handle a gas heater. Get a BCA registered contractor or a Licensed Gas Worker
DO NOT allow modification to the heater. It is dangerous!
The most dangerous modifications are bypassing the safety controls
The most serious being bypassing the solenoid valve. This is removing the safety valve that will shut off the whole system when it detects a gas leak.
Refer to the table below to ascertain the issue.

code error guideline
| Code | Fault | Point to Check |
| 03 | EZ Link | Check communications cable. Ensure dip switch 4 on DIP1 set of switches is in the ON position on both heaters. |
| 05 | Imperfect Combustion Alarm | Clean air inlet filter. Clean combustion air fan. Clean heat exchanger fins. Check for adequate combustion air ventilation openings and clean if necessary. Check vent system for partial blockage and correct as necessary. |
| 10 |
Air Supply or Exhaust Blockage Warning code not a fault code. |
Check all vent components for proper connections. Ensure there are no restrictions in the flue inlet or exhaust. Ensure condensation trap/drain was installed correctly. Ensure heat exchanger fins, fan, and air intake are not blocked. |
| 11 | No Ignition | Ensure gas supply to the appliance is turned ON. Ensure gas type and pressure is correct. Bleed all air from gas lines. Ensure gas line, meter, and regulator are sized properly. Ensure appliance is properly grounded. Check gas solenoid valves for open or short circuits. Ensure igniter is operational. Check igniter wiring for damage. Check heat exchange thermistor and transformer. |
| 12 | Flame Failure |
Ensure gas type and pressure is correct. Bleed all air from gas lines. Ensure flame rod wiring is correct. Check flame rod for carbon build-up. Ensure gas line, meter, and regulator are sized properly. Ensure appliance is properly grounded. Check gas solenoid valves for open or short circuits. Check power supply for proper voltage and voltage drops. Disconnect remote control. Check heat exchange thermistor and transformer. |
| 14 | Overheat Limiter Fault |
Ensure high fire and low fire gas burner pressure is correct. Check gas type of unit and ensure it matches gas type being used. Check heat exchanger for cracks and/or separations. Check gas type connector. Check for restrictions in airflow around unit and vent terminal. Check over heat limiter wiring and ensure it is plugged in correctly. |
| 15 | Boiling Safety Device |
Check for closed water heater inlet valve or restrictions in cold water inlet pipe (must be fully open). Check for clogged heat exchanger (scale build up). On a commercial water heater, lower the set point temperature below 82°C at high altitude. Check heat exchange and hot water outlet thermistor. |
| 16 | Over Temperature Warning |
Check for blocked heat exchanger. Check for restrictions in airflow around unit and vent terminal. Check PGFR, heat exchanger thermistor and hot water outlet thermistor. |
| 24 | Malfunction of Operational Switch |
Disconnect remote control and retry. Verify unit is electrically grounded. Ensure Min, Max and/or Adjuster buttons have not been inadvertently depressed. |
| 29 | Heat Exchanger Outlet Temp. Too Low | Check air intake filters and heat exchanger fins. |
| 31 | Water Inlet Temperature Sensor Fault | Check sensor wiring is intact and not damaged. Check and clean scale from sensor if necessary. Ensure resistance is correct. |
| 32 | Heat Exchanger Temperature Sensor Fault | |
| 33 | Outgoing Water Temperature Sensor Fault | |
| 34 | Ambient Air Temperature Sensor Fault | |
| 35 | Improper Thermistor Connection | Check that all thermistors are connected to proper connections on PCB. Ensure the hot and cold plumbing to the heater is not reversed. |
