Unlike the solid fuel stoves the sides of the stove do not get hot,the unit can be nearer to surfaces then other stoves.the unit is actually further away from wall surfaces then the manufactures recommends.
Top of stove only gets warm not hot,this is where the hooper containing the pellets is.The pellets are compressed saw dust,they come in 15kg bags paid £3.40 per bag,have only used one bag in the past week.unlike a solid fuel squirrel you can turn stove off at the press of a switch and on when required.there are 5 power settings and you can set stove to what temp you require.when the stove reaches required temp it switches to eco mode and just ticks over.
Of course the real test will be when the winter comes.
Has been working fine from batteries supply from solar panels.
Narrowboat chelonian has had one for several years and gives more info on his web site http://chelonian.co.uk/about/wood-pellet-stove
As for the squirrel it had a crack in the back plate,took a club hammer to it and in the skip it went !
