(Mine is the 5kw version) Some of the bits feel a little cheap but then it is cheap. But so far so good. I���ve got mine heating an 18ft by 10ft wooden workshop and it does this with ease so I���m really happy with it so far. I may upgrade the fuel line and filter at some point just for slightly better quality ones. But if you���re fairly handy then they���re easy to fit and commission. Like I say I���m really chuffed with it so far, for the money it���s spot on but time will tell if there are any issues. One thing I would always recommend around any fuel burning appliances is a carbon monoxide alarm just to be on the safe side.
