    Overview

    The Cosyglow series of radiant gas heaters from Rinnai are a customer favourite, thanks to their simple and reliable designs. This model is designed to connect to an LPG bottle, but a similar model with all of the same features is also available for natural gas connections. And because it uses a battery ignition system, it doesn’t need to connect to a power point to operate, so you can put away that extension cord.
    Compact design

    The Cosyglow gas heater doesn’t take up too much of your home’s floor space, and there are moulded handles at the sides to help you move it from room to room as needed. According to Rinnai, the Cosyglow can effectively heat rooms between 23 and 42 square metres in size, depending on your local climate – smaller rooms in colder areas, and larger rooms in milder regions.

    Simple manual controls

    The heater is operated using manual switches, consisting of the on-off switch, and the slider for half and full heat. To start the heater, push in the button underneath the On switch, slide the switch down, and hold until ignition.

    Three Year Warranty

    For your peace of mind, this product comes with a manufacturer’s warranty. We also offer extended coverage with our Customer Care plans on select products. See the accessories section above for the terms and conditions.

    Enjoy heat wherever you want

    Because this heater connects to bottled gas and uses a battery ignition system, it’s possible to take it with you when you move house without requiring fiddly disconnection/reconnection. You can also move it from room to room for quick and simple spot heating.

    Check if it's lpg or propane
    I bought this and I'm pretty sure I ordered an lpg version but the sticker on the back says propane only. Hopefully this is ok as we are using it

    Questions & answers

    How long would this run for with an 8.5kg swap and go gas bottle? Chrisa · 2019-06-24
    Good morning, Thank you for this question, Sorry to say you are unable to connect these heaters to any size portable gas bottle if you are wanting to install an LP gas heater your plumber must install a bottle on the outside of the property these are normally about 45kg then run a gas pipe from the bottle to where you are wanting to have your room heater with an approved gas bayonet fitting in the wall. Best to talk to your plumber about LP gas installation and wall bayonet location. I hope this information will assist you when shopping here with us at Appliances online.
