As temperatures drop across Torquay and the Surf Coast, gas heaters become an essential part of keeping homes warm and comfortable through winter.
But while gas heaters are generally safe when properly maintained, there’s one risk every homeowner should understand:
Carbon monoxide exposure.
Carbon monoxide is often called the “silent killer” because it can’t be seen, smelt, or tasted. That’s why regular servicing and awareness of the warning signs are so important.
What Is Carbon Monoxide?
Carbon monoxide (CO) is a poisonous gas produced when fuels such as natural gas don’t burn properly.
Faulty, damaged, or poorly maintained gas heaters can potentially produce dangerous levels of carbon monoxide inside the home.
Because the gas is invisible and odourless, many people don’t realise there’s a problem until symptoms appear.
To help prevent issues, regular gas heater servicing in Torquay is strongly recommended.
What Causes Carbon Monoxide in Gas Heaters?
There are several reasons a gas heater may begin producing carbon monoxide, including:
- Dirty or blocked burners
- Cracked heat exchangers
- Poor ventilation
- Faulty components
- Lack of regular maintenance
Even heaters that appear to be working normally can develop internal faults over time.
That’s why professional servicing and carbon monoxide testing are so important.
Common Symptoms of Carbon Monoxide Exposure
Symptoms can sometimes resemble a cold or flu, making carbon monoxide difficult to identify initially.
Common symptoms include:
- Headaches
- Dizziness
- Nausea
- Fatigue
- Shortness of breath
- Confusion
Symptoms often improve when leaving the house and return again once back indoors.
If you suspect carbon monoxide exposure:
- Turn the heater off immediately
- Open windows and doors
- Leave the area if symptoms are severe
- Seek medical advice if necessary
- Contact a licensed gas plumber to inspect the appliance
Warning Signs Your Gas Heater May Not Be Safe
Aside from physical symptoms, your heater itself may show warning signs that something isn’t right.
These can include:
- Yellow or orange flames instead of blue
- Soot or black marks around the heater
- Strange smells during operation
- Condensation build-up near windows
- Reduced heater performance
- Unusual noises

How Regular Servicing Helps Prevent Carbon Monoxide Risks
One of the best ways to reduce the risk of carbon monoxide is through regular professional servicing.
During a service, a licensed technician can:
- Inspect internal components
- Check for damage or wear
- Test ventilation and airflow
- Perform carbon monoxide testing
- Ensure the heater is operating safely and efficiently

Should You Install a Carbon Monoxide Alarm?
Many homeowners choose to install carbon monoxide alarms for added peace of mind.
These alarms can provide an early warning if dangerous CO levels are detected inside the home.
While alarms are valuable, they should never replace regular servicing and maintenance.
The safest approach is:
- Routine servicing
- Proper ventilation
- Carbon monoxide alarms where appropriate
Older Gas Heaters May Need Extra Attention
Older heaters can still operate safely if properly maintained, but they may be more prone to wear and internal deterioration over time.
If your heater:
- Hasn’t been serviced in years
- Frequently breaks down
- Is difficult to ignite, or won't stay lit for very long
- Produces unusual smells or soot
- Struggles to heat effectively
…it may be time for a professional inspection.
