Eberspacher Heating Systems
HOW THEY WORK

Eberspacher Airtronic heaters
Tiny measured fuel gets pumped into the heater which is mixed with the combustion air and burnt in the combustion chamber, the hot gasses pass through the inside of the heat exchanger before reaching the exhaust. Heating air is drawn into the front of the heater and is heated as it passes over the outside of the heat exchanger. The heating and combustion air paths are completely separated. Eberspacher Airtronic heaters adjust their heat output automatically between Boost, High, Medium, Low & Standby settings. Other models may have a different number of settings, the oldest have only full or half heat.
