Webasto Diesel Air Heaters

Diesel air heaters work by drawing in cool air from the environment and passing it through a heat exchanger that is heated by the combustion of diesel fuel. The process starts with the diesel fuel being pumped into the heater’s combustion chamber where it mixes with air and ignites. The combustion heats the heat exchanger, which in turn warms the air that is being drawn in. This warm air is then circulated into the desired space, such as a boat cabin, using a built-in fan. The exhaust gases from the combustion process are safely vented outside, ensuring clean air within the living space. Advanced models often feature thermostats to maintain a consistent temperature.

Webasto Diesel Liquid Heaters

Diesel liquid heaters operate by heating a liquid coolant through the combustion of diesel fuel, which is then circulated throughout the boat’s heating system to provide warmth. The process begins in the heater’s combustion chamber, where diesel fuel mixes with air and ignites to generate heat. This heat is transferred to the coolant fluid, usually a mix of water and antifreeze, which is pumped through a network of pipes and radiators within the vessel. As the heated coolant flows, it radiates warmth into living spaces and can also be used to heat domestic water or to preheat engines. The system’s thermostats and controllers ensure a consistent, adjustable temperature, enhancing comfort while maintaining high efficiency and safety.
