We agonised about the best way to heat our huts. First and foremost, they are double insulated using both fibre and rigid/multifoil insulation in every surface to help the heat stay in.

The vast majority of shepherd's hut have a wood burning stove. This is the traditional option, but we wanted to be sure that the choice we made was the most practical, not just following convention.
Yes there is the romance of a wood burner, the flickering flames and the glow of a fire, and in our research we found that some enjoyed the idea of the hands on building of a fire. The reality however can be quite different.
For starters there is the dust and ash that a wood burner creates. Those bright clean walls and floors may not stay fresh for long!  
Unless you have an extraordinarily long flue, a wood burner does not draw as well as it might which can not only result in a less efficient burn, it can also pump smoke out in to your room when restocking the fire.
Building a fire can be an art which not everyone has experience in. On a wet or chilly day you may want to warm up the space quickly and easily rather than collecting wood and embarking on setting a fire.
You will need storage for your wood close to the hut and a steady, seasoned supply (not cheap these days), chopped up small to fit in the tiny firebox.
Temperature control can be tricky and getting a fire going fast and to an appropriate level of warmth can be awkward too.

The Everhot stove plugs in to a normal socket and provides ample heat for small spaces. It is efficient and ready to be run by solar if you choose that route. It is super cute to look at, comes in stacks of gorgeous colours and even comes with an integral oven! Hoorah! For us, there was no contest.
