There are two models. The 079K (kerosene/paraffin) and the 079D (diesel).
The 079K uses the same pressurised system as the Taylors cookers. Max heat output 2.1 KW.
The 079D is drip (gravity) fed diesel fuel from a header tank. Max heat output also 2.1KW. The diameter of the chimney section is greater than the 079K, requiring a larger opening through the deck. Something to bear in mind when planning your system.
Both versions are available in stainless steel or brass finish, subject to stock availability.
