Risks of flueless heaters

When heating your home with gas, heat, air pollutants and water vapour are produced. Flueless gas heaters release those pollutants directly into your home. Use flueless heaters only in rooms with adequate ventilation.

Warning

There are restrictions on the installation of flueless heaters operating on Natural Gas in Victoria. Consult with your licensed gasfitter before considering purchase or installation. This restriction also applies to new and second-hand flueless heaters imported from interstate and overseas. Cabinet heaters are not permitted (mobile heaters containing an LP Gas cylinder)

Health hazards

The effect of exposure to air pollutants on your health depends on the type and amount of pollutants to which you are exposed, and can occur immediately at the time of exposure or be delayed.

The major air pollutants from fossil fuels such as gas are Carbon monoxide and nitrogen oxides. Young children and people with asthma or other respiratory diseases are most at risk from air pollutants. Water vapour is not regarded as an air pollutant, but the accumulation of moisture in the room being heated may lead to the growth of moulds and dust mites, which have the potential to affect health.

The emission levels vary depending on the type of heater, the design of the burner and regular servicing.

The level of emissions in the room will vary according to:
  • The use of the room
  • The size of the room compared to the input of the heater
  • The ability of the room’s ventilation to remove or dilute emissions.

Protect your health and safety

When using flueless gas heaters:
  • Always follow the manufacturer’s instructions
  • Keep appliance grilles and vents clear of obstructions and free of lint and dust.
  • Ensure room ventilation is adequate
  • Minimise usage per day. Consider a flued appliance where long usage is envisaged..
  • Never use an unflued gas heater in the room where you sleep or in a caravan.
  • Have your heater serviced before each heating season
