The 1800 is ideally suited for use in sailboats where every amp counts, due to its extremely low power consumption. The1800 has two warm air outlets, each of these can be fitted with warm air tubes up to 5 meters long and can have a second outlet branched from them offering four outlets in total. This heater is ideal for installation within the cabin of the boat because of its quiet operation and it pulls the air to be heated from the surrounding area. The 1800 is supplied with a control panel which offers full heat, half heat and fresh air ventilation. A thermostatic control that adjusts the heat between maximum and minimum settings is available for the 1800 heater.
