The Lofoten diesel heater is a mid size floor mounted heater for boats up to approximately 40 feet in length. This practical model incorporates a small hot plate that is ideal for boiling a kettle. The Lofoten should be ideally mounted as centrally as possible for best heating effect through convection and radiation. 4? flue accessories are required and an optional water coil (back boiler) is available for heating hot water in a calorifier.
