Anyhoo, the Prity will probably be leaving the yurt this weekend and the space it took up will be utilised as a kitchen area for preparing and cooking nosh. It's an ideal spot, right under the lightest area of the yurt and near what will soon be a ventilation hole (where the chimney went).
Here's the heater (2.5kw technically), will run for about 17 hours on a 3.8l fill.

Obviously it's possible that it won't be up to the job, but the advantages of running something as stable and compact as this heater, outweigh the advantages of a fire, which are mostly aesthetic.
