Probably not. There are two main things to consider, the available space and the available power.
Space - the ventilation pipe is 110mm in diameter and the initial slow 90º bend is installed behind the toilet, which will take up considerable room.
Power - the Separett BASIC and FAMILY are designed for 100% mains electric use. During the initial phase (about 40 mins), the temperature of the incineration chamber is raised to 550ºC, during which time, the current draw is approximately 10 Amps (1.8Kw) continuously. Once at this temperature, the incineration phase commences, which maintains the temperature for the duration of the cycle (20-40 minutes depending on the model and the program chosen).
