In the past two years, Energy Safe has received nearly 50 reports of safety incidents and issues involving home gas and electrical heaters, or heating appliances.
Energy Safe chief executive Leanne Hughson said early winter was the time when hidden faults emerged.
“Many people don’t think twice about turning a heater back on after months of sitting unused, but early winter is when underlying faults and safety issues can start to show up,” Ms Hughson said.
“Gas heaters should be serviced by a licensed gasfitter at least every two years, as the carbon monoxide they can emit can’t be seen or smelled and people may not realise there’s a problem until they become unwell.”
Heating hazards such as carbon monoxide can be difficult to detect.
Common symptoms of carbon monoxide poisoning can include headaches, dizziness, nausea, shortness of breath and fatigue, and can often be mistaken for flu-like symptoms.
Electric blankets are another concern, with Energy Safe recording seven fires involving electric blankets over the last year.
“Electric blankets can become dangerous if they are damaged, excessively worn or left switched on for long periods,” Ms Hughson said.
“People should inspect electric blankets for signs of wear or damage before using them each winter and follow the manufacturer’s usage and cleaning instructions carefully.”
Energy Safe also reminds Victorians to report heater issues to agents if renting, never use outdoor gas appliances inside and avoid overloading power boards.
