Its constant and pleasant air circulation makes air heating highly comfortable. You don't see it, but you do feel it. A system of ducts and inconspicuous grilles ensures that the supplied air is divided over the entire room. An effective filtering system removes all unwanted dust particles from the air. The slowly circulating air quickly brings the rooms to the desired temperature, while the heater's high efficiency keeps the fuel costs low.
Direct or indirect fired
There are two air heating systems: direct or indirect fired.
- With direct heating (Allure) a high-efficiency gas fired unit arranges the heating.
- With indirect fired units, an external unit supplies hot or cold water. The modulating, indirect fired heat exchanger (Elan) uses a water-air exchanger to convert hot or cold water into hot or cold air.
