I brought to live aboard from THE NEW BOAT Co in 2006 with a webasto heating system the heating has never worked from day one. During this time THE NEW BOAT Co have done there best to help by replacing the entire system twice and at there expense to no avail. Eventually a webasto engineer was sent to test the system over six weeks with white diesel it worked perfecly , it run hot enough to burn off the carbon and sulpher residue which was apparently the problem. Webasto still insist that red diesel is adequate to run the system whilst several boat owners will dissagree.
