The Shocking Truth About Your Gas Heater: Why Electronics (and Expertise) Matter More Than Ever
For many Hallam homeowners, a “gas” ducted heater, like the trusted Bonaire systems common across the South Eastern suburbs, conjures images of simple flames and basic mechanics. While gas is indeed the heating source, the reality inside that familiar casing is a complex world of electronics. Understanding this is crucial not just for efficient heating, but for your safety and your wallet. This article delves into why your gas appliance is more electronic than you think, and why specialised expertise is non-negotiable for its maintenance and repair.

Beyond the Burner: The Electronic Brains of Your Bonaire Heater
Modern Bonaire gas ducted heaters (and indeed, most models from the last 15 years) are sophisticated systems where nearly every function is governed or monitored by electronic and electrical components. Let’s break down the process:
1. The Spark of Safety – Ignition & Combustion:
- Gas enters the heater via a connection, but it won’t reach the burners until a series of electronic safety checks are passed.
- Key Condition prior to ignition creates flame:
1/. The combustion fan: This fan ensures dangerous exhaust gases like Carbon Monoxide (CO) are safely expelled; Fan’s Retail Price (April 2025: $250 - $470); must be running correctly.
2/. Pressure switches: The Combustion exhaust is monitored by the Pressure switches. These sensors confirm the combustion fan is creating the correct airflow before allowing gas flow. Switch’s Retail Price – April 2025: $75 - $180.
If not sensing signal from any of the switch correctly, the control system (electronic central control module) won’t allow gas to flow, preventing a dangerous buildup of unburnt gas, or deactivate if the heater is already ignited to avoid CO spillage.
3/. The gas valve itself: Controls the flow of gas to the burners, operated and monitored by the main electronic control board for safety and performance; Part Retail Price (April 2025): $250 - $550; While containing mechanical parts, is opened, closed, and modulated based on precise electronic signals from the main control board.
It’s not just an on/off tap; it’s an intelligently controlled device.
2. Preventing Meltdown – Overheat Protection:
The burner assembly is protected by at least two safety switches (over-temperature sensors)

Description: These critical sensors detect if the heat exchanger or burner area is getting too hot and will shut down the heater; Part’s Retail Price (April 2025): $30 - $80; If they trip, the heater stops immediately to prevent damage or fire.
3. Delivering the Warmth – The Fan Motor & Duct Sensing:
Once the flame is established and recognised by the electronic sensing circuitry, the heat exchanger transfers heat from the burned gas to the air that warms your home, utilising the force of the room fan motor. When the inside temperature reaches its designated operating level, the main electrical fan motor (indoor blower), responsible for distributing the warmed air throughout your home, stops and waits for next heating cycle.

This powerful motor circulates warm air through your home’s ductwork. Retail Price (April 2025: $450 - $810) is activated by the control module. Even the ductwork can be monitored for temperature to prevent overheating, ensuring safe distribution of warm air.
4. The Central Nervous System – The Main Control Module (PCB):
All sensors, switches, and motors are wired back to a central Printed Circuit Board (PCB) or main control module

Description: The “brain” of the heater, processing all sensor inputs and controlling all operations. Retail Price (April 2025): $350 – $970.
If any sensor detects an anomaly, it signals the PCB, which will typically shut down the heater completely. Many of these fault-triggered shutdowns require a reset by a qualified technician, who can also diagnose and rectify the underlying cause.
The Control Modules (Central Control Electronic PCB) function as intelligent computers until they fail. There are several occasions where error codes originate from a faulty control module like this, creating confusion for plumbers and other tradespeople who are not trained or equipped to handle such situations. Employing a trial-and-error replacement method carries significant risks, not only potentially damaging related components but also causing unexpected faults that cost more at the end.
5. Comfort Control – The Thermostat & Heating Cycle:

Wall Thermostat’s Function: Measures the ambient room condition and converts it into an electronic signal, which is transmitted to main control module to activate or deactivate the heating cycle. Thermostat Retail Price (April 2025): $150 – $370.
Warm air is distributed through vents (registers). This air eventually returns via an intake duct to the heat exchanger to be rewarmed.
When your room reaches the set temperature, the thermostat signals the main control module to enter standby mode. When the temperature drops by a preset amount (usually 1∘C to 2∘C), the cycle restarts.

The Evolution of Heating: Efficiency, Safety, and Electronics
The basic principle of warming air with gas isn’t new, but the methods of control, distribution, efficiency, safety monitoring (especially for Carbon Monoxide – CO), temperature sensing, and zoning have been revolutionised by electronics.
A properly functioning electronic control system ensures:
- No CO spillage: If the combustion fan and pressure switches are working as designed.
- Optimised combustion: Gas isn’t burnt “too much” or “too little,” preventing overheating or insufficient warmth. This reliance on electronics underscores the importance of specialised skills, proper diagnostic equipment, and experience when dealing with modern heaters.
The Dangers of DIY and Unqualified Trades: A Serious Warning
The complexity of these electronic systems, coupled with the presence of mains voltage (240VAC), makes heater repair a job strictly for qualified professionals.
- It’s Not Just Plumbing: While gas is involved, a plumber without specialised electrical training is not equipped to diagnose or repair the intricate electronic control systems. The title “plumber” does not equate to “electrician.”
– - High Voltage Hazard: Electrical circuits in these heaters carry 240VAC. Understanding electrical safety is paramount.
- Currents over 10mA (10 milliamperes) can cause a painful shock.
- At 0.2A (200mA), death is a common outcome.
- Up to 0.5A is almost certainly lethal, often accompanied by severe burns.
Electrical burns are excruciatingly painful.
–
- Victoria’s Regulations: Here in Melbourne, Victoria, a specific “Fault-Finding” license is required for individuals working on electrical equipment running on mains power like 240VAC. Furthermore, after major electrical component replacements (like a main control module, fan motor, or compressor energised by over 50VAC or 120VDC), an Electrical Safety Compliance Certificate (ESV Certificate of Electrical Safety) is mandatory.
– - Don’t Open the Cover: Attempting to “fix” things yourself, or allowing an untrained individual to do so, is illegal and highly dangerous. This is especially true if the heater is in a confined space or tightly screwed shut. We’ve seen too many instances where covers are left open, compromising safety for everyone. Property damage or injuries resulting from unlicensed work are often not covered by insurance. Do not DIY, no matter what you’re told.
