Gas Heater
Paloma gas heaters were initially distributed in Singapore by Hong Leong following their acquisition of Rheem Far East in 1985. In 1988, Paloma acquired Rheem, and Rheem Manufacturing Company (Singapore) Pte Ltd continued to distribute Paloma heaters independently of Hong Leong until around 2010. Since then, the technical and logistics teams for Paloma in Singapore have been disbanded, and there is no longer an official distributor for Paloma products in the region.
However, with extensive experience in servicing Paloma gas heaters, Homeone is the most capable vendor in Singapore for the repair and replacement of these units.

Compatibility
Your Paloma gas heater offers unmatched compatibility, allowing for easy replacement with any gas or electric heater brand. Enjoy the freedom to choose the best water heating solution for your home.
For Rinnai, you can choose from the top-of-the-line Rinnai REU-2008W-RS or the more affordable REU-2024WP-RS.
The Macro MA-20WOD offers exceptional value, featuring built-in Wi-Fi for mobile app control.
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.
For conversion to an electric storage heater, selecting the right capacity from brands such as Rheem, Ariston, or Joven will provide an experience similar to that of a hotel.
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 and 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.

Deployment
Same-day urgent call-outs are available. Site assessments with tests cost $50. Gas heater replacements, including U-gauge testing with EMA LGSW certification (according to Gas Supply Regulations 21), ensure for safe use in 4 hours. Despite fast response in attendance, the gas heater replacement work will also include:
For plumbing works, replacing sections of hot, cold, and recirculating pipes (where applicable) with stainless steel fittings and new stop valve for enhanced durability, especially for outdoor installations. Recycling old fittings has proven ineffective, as repeated untightening and tightening can cause material fatigue, leading to ruptures in the long run.
2For gas work, replacing key gas pipe fittings, such as the gas valve and removal of union, which are the two most common components prone to gas leaks after heater replacement due to ageing. A section of the gas pipe either made of galvanised iron (GI) or copper will be replaced due to possibility of it being weakened after repeatedly tightening and dismantling.
The copper pipe specifications will have to be Type Y or table Y complying with BS EN 1057.
3
This work must be carried out or supervised by a fully Licensed Gas Service Worker (LGSW) from the EMA, not by someone with only a Restricted Licence. Testing of hot water at the fittings to ensure all are functioning as designed.

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
- To bypass the thermocouple and
- Removal of the solenoid valve and replace with an empty pipe so that the heater doesn’t shut down when it detects a gas leak.
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.

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. |
| Code | Fault | Remedy |
51 | Gas Inlet Solenoid Valve Fault | Check gas inlet solenoid valve wiring for loose or damaged terminals. Check flame rod. |
| 52 | PGFR Valve Fault | Check PGFR valve wiring for loose or damaged terminals. |
61 | Combustion Fan Failure | Ensure fan motor will turn freely. Motor will operate with a small amount of restriction. Check wiring to motor for damaged and/or loose connections. Ensure the flue length does not exceed max length and number of bends. Check transformer and PCB. |
65 | Water Volume Control Fault | Check water flow solenoid valve wiring harness for loose or damaged terminals. Check for proper voltage to water flow solenoid. |
66 | Water By-Pass Control Fault | Check water by-pass solenoid valve wiring harness for loose or damaged terminals. Check for proper voltage to water by-pass solenoid. |
| 71 | Gas Inlet Solenoid Valve Control Fault | Check gas inlet solenoid valve wiring for loose or damaged terminals. Ohm out solenoid valve. |
72 | Flame Sensing Device Fault | Ensure flame rod is touching flame when unit fires. Check inside burner chamber for any foreign material blocking flame at flame rod. Check all wiring to flame rod for damage. Check flame rod for proper voltage. Remove flame rod and check, clean with steel wool. |
76 | Communication Fault with Remote Control | Check remote control wiring for loose or damaged connections. Bypass remote control cable by connecting remote control directly to remote control terminals on PCB. Replace cable if found to be faulty. |
79 | Fan Motor Current Fault | Ensure fan motor will turn freely. Motor will operate with a small amount of restriction. Check fan motor for proper voltage and for water (condensation) damage. |
| 80 | Gas Cut-off Failure | Ohm out all solenoid valves. Check voltage of all flame rods. |
