Why Would Anyone Buy a Unflued Gas Heater Considering The Pollutants It Releases?

This is probably a question to non-Victorians. Not sure how harmful it is using an unflued LP gas heater? They go in a bit of detail with some facts in the NSW Health website,
https://www.health.nsw.gov.au/environment/factsheets/Pages/u…

But why would they still allow it to be sold? Is it like it is not that harmful if used in an open area like a living room? Or is it that it could be used with a CO/NO2 detector or something?

What is better ultimately a flued or an unflued gas heater?

    It's safe when used correctly. But using it correctly means leaving a window open for air flow, and that means a chill draft coming in and wasting energy.

    Go with a flued, or even cheaper to run, a reverse cycle air-con.

    • Thanks, I'll probably go with a flued one. Gotta make some provision for it though.

    Wow didn't even know that was health hazard. Been using one in my bathroom for years to heat it up before I take a shower…

    • Well, I think it is not harmful if there is proper ventilation. But I am not sure to what extent. As in how much open a room should be. Is it better to leave a window open for a small portion (10-15 cms like)

  • People have died due to Carbon Monoxide poisoning because of unflued or poorly flued heaters. It tends to be a bigger problem in countries where their homes are better sealed due to cold. It might be worth considering getting a carbon monoxide detector.

    We have one, but our house is pretty much a sieve with doors.

    • That sounds pretty wide area. How's your experience been if I may ask? How long have you been using it and do you have any allergies or your family?

      • Some mild asthma. Using for years with no issues. It is not for closed off areas.

  • Could be because they are cheap? Some landlords will buy cheapest thing that will work that work that meet requirements for living.

    But yeah most of the time it’s probably an older product that someone wanted to save a few hundred on and so chose the cheaper option.

      Unflued ones are definitely not cheap. However they are cheaper than a flued one. e.g, Rinnai branded unflued convector heaters are in the range of $1300-$1500. Same brand flued ones cost around $2000.

    Half the country lives in houses with directly attached vehicle garages which poisons them and their families.

    • How's that?

      • Indeed. The comment would only make sense if someone left the car running in the garage (big no-no).

          A good reason to drive in and not reverse in.

    A friend lives in a rental property with an unflued gas heater. When I asked him if he could turn on the heat, he said "I seldom use it as the heater stinks". Wow. Carbon monoxide has no odour, but if you can smell other chemicals coming off the thing doesn't that suggest there's a problem?

    In colder parts of Japan it's not uncommon for people to use indoor kerosene heaters. Unflued. It's mad.

    • I am worried about the long term affects of using such an appliance. I guess it is safe to use an unflued heating appliance if there is proper ventilation for fresh air flow. The incidents that have caused the deaths are more or less due to using of such appliances in a smaller closed rooms for a long duration.

      Kerosene heaters sound insane. It also smells really bad but I hope they have a pretty good fresh airflow to remove all the pollutants

      • to get rid of kero smell, I used to keep a pot on top of the heater with water in it

  • Honestly some people grew up with it and it has become force of habit that now they like it.

    Kind of like petrol smell or second hand smoking we realise that sometimes we encounter it so we live with it and if you are me you trick your brain to like it because might as well suffer happy than suffer sad.
