    Questions & answers

    I am going to buy a Rinnai Gas Heater AV25 from your online platform , I live at Glen Waverley Vic 3150, I just want to know how much for the installation with your team when the product free delivery to my home? Jason · 2025-06-04
    Hello Jason, Thank you for your question about our product. Please check the notes section on our website regarding the installation of portable gas room heaters, as these are not allowed in all states. In Victoria, new gas installations must utilize vented gas room heaters only. If you have an existing portable gas connection, you may connect and use it; however, all new connections MUST be vented. You can choose from our selection of vented gas room heaters on our website, but please note that we do not offer installation services for gas room heaters. I hope this information will assist you when shopping with us at Appliances Online. Our Sydney-based team is available 24/7 to assist you at Ph: 1300-000-500. Colin Jones, Appliances Online
    i'm interested in this heater, but don't understand how the need for ventilation (i.e. window cracked) is balanced against keeping the area warm. Another related question : can the ducted system's fan module be used, or is that spreading CO? alison · 2025-02-20
    Hello Thank you for your question about the product. While these heaters are very efficient, it is important to note that they are portable and non-flued. For any portable gas room heater, it is best to keep a window slightly open to allow fresh air to enter the room. Additionally, placing a ducted air conditioner on will not help in this situation, as it removes moisture from the room but recirculates the same air instead of bringing in fresh air. I hope this information will assist you when shopping with us at Appliances Online. Our Sydney-based team is available 24/7 to assist you at Ph: 1300-000-500. Colin Jones, Appliances Online
