Gas Heater Help

gday im sure this has been done before but im looking at buying a gas heater, ive got 2 young kids so i was goin the way of convectional heaters is there only 2 brands (rennai and everdure) what goes alright for heating up the room

any help appreciated
thanks

don't know if you are natural or lpg gas, I have two rennai heaters on lpg . Each heater if approx one third of the way into large 17 meter long open plan living room kit and dine cathedral ceilings and they will heat the room up in no time at all . I am very happy with the rennai.:)

those shiny new little everdure heaters are pretty good for the money, they have a child lock-out setting too on the remote.
