Producing up to 14,300 BTU / 4.2kW, the Megaheater XL uses high-efficiency radiant tiles to provide effective heat distribution. Because the heater operates entirely from gas, there’s no requirement for a mains electrical connection, making it particularly useful for outdoor leisure setups where access to electricity may be limited. Brunner specifically identifies the Megaheater as suitable for outdoor use. Brunner
For quick and convenient operation, the heater incorporates piezoelectric ignition, while a protective front grid surrounds the radiant heating area. A large integrated handle makes the unit easier to carry between storage and your outdoor setup. Despite its powerful output, the XL measures a relatively compact 50.6 × 17.5 × H40.3cm and weighs 5.2kg. Brunner
Safety is supported by several important features, including an oxygen depletion sensor (ODS) and flame failure device. Brunner also equips the heater with a high-quality pressure-reducing valve, while its operating pressure is specified at 30mbar. Brunner
The Devil Megaheater XL offers useful flexibility when it comes to fuel. It can operate from standard threaded EN417 450g gas cartridges or suitable gas cylinders. Brunner also includes a gas hose for cylinder connection, giving you greater choice when configuring the heater for your outdoor setup. Gas consumption is specified as 190 + 190g/h. Brunner
Powerful, portable and completely independent of an electrical supply, the Brunner Devil Megaheater XL provides an effective 4.2kW heating solution for outdoor leisure use.
