I had to make a comment. I am surprised that no one appears to want this machine. So many on here moan about how cold their van is and how best to stop things from freezing. This is realy your answer. If you went to the supplier for this he or she would want the best part of about 700 quid. I have always suggested to insulate the van but so many people just wack their machines in and dont bother. If this is the case then put this type of heater in. Best, Dave.
