Modern, spacious, open plan living represents the biggest challenge for any heating system. But it's hardly a challenge for our biggest combustion heater, the aptly named, Mega heater.

With an output of 35kW (120,000btu), it's one of  Australia's most powerful freestanding heaters and will turn 40 squares of open space into warm, comfortable living area. Powerful it may be, but the Mega is certainly not a brute to look at, with a softer appearance through its contoured door that opens wide to accept large logs. You can even harness some of Mega's power by fitting the optional water jacket to heat your water system.
