    Overview

    This convenient portable heater makes it simple to warm small spaces such as single rooms. Thanks to its battery ignition, the heater does not need connection to a power supply, making it even more portable. Stay warm and cosy with this simple gas heater.
    Easy heat adjustment

    The sliding Hi-Lo burner lets you easily adjust the intensity of your heating, whether you want to warm a room quickly or gently.

    Designed for convenient travel

    This compact, portable design uses a D battery rather than a wired electrical connection, allowing you to effortlessly ignite the heater anywhere it’s needed.

    Safety-conscious

    Built-in safety systems include a tilt switch, which shuts off the appliance if it is knocked over, and flame failure, which shuts off the gas supply if the heater’s flames are ever extinguished.

    Good for small rooms or spot heating

    Whether you want to transform a smaller room into a more comfortable place to relax, or keep the area around your favourite living room chair warm on the long winter nights, this is the heater for you.

    Questions & answers

    Does this blow out heat ? I have a gas point in my home with gas bottles outside would this work for me ?? Sarah7782 · 2019-11-26
    Good morning, Thank you for this question, sounds like you have everything set up for LPG which is great no this model does not have a fan it's a 2-panel radiant gas heater if you are wanting a radiant heater with fan-assist then the Rinnai Titan Unflued LPG Radiant Heater 151L, if you want simply fan only gas heater then Rinnai Enduro Unflued LPG Convector Heater EN13L please check the room size that you require don't just simply buy on price if the unit is too small then this will not service the room size we do provide a guide for Australia and what heater to view on our website. I hope this information will assist you when shopping here with us at Appliances online. Colin Jones, Appliances Online
    Can they be hooked up to a 9kg LPG gas bottle? Benj · 2019-07-23
    Good morning, Thank you for this question, Sorry no you are unable to connect any LP portable gas room heater to any size bottle inside your property, LP bottles need to be installed outside and your plumber to run the gas connection inside with a bayonet fitting into your wall. I hope this information will assist you when shopping here with us at Appliances online. Colin Jones, Appliances Online
    Please advise if you 252SN Model has retained the same shape/design for the last 10 years or is there a more current model with different style Thank you Margaret Margaret · 2019-03-18
    Good Morning, Thank you for this question, what i see online that this model has maintained a similar look has not really changed that much, you are talking about the Granada 25 series which is the largest portable gas room heater not the model you have attached which is a different model. i hope this information will assist you when shopping here with us at Appliances online.
