I have been using this for about a week to heat a 40ft Dutch Barge. It is really quite powerful and so far so good. If it does not break down it represents insanely good value for money pumping out much more heat than my German branded model. I put two outlets on it. Needed more ducting and grills but otherwise all there. The instructions are next to useless which is why I knocked off a star but I found most of what I needed on you tube videos. I think it uses about .5 to .75 litres of diesel an hour which may seem a lot but works out much cheaper than a gas heater.
