Chimney Effect - The De'Longhi TRD4 0820T Dragon 4 Oil Filled Radiator convects air through its "chimney" and cold air is channelled through the hottest part of the radiator, accelerating hot air through vents for effective heating and providing a fast flow of hot air that quickly warms the whole room. More Radiant Surface - With an enlarged fin shape, it delivers an increased chimney (convective) effect for faster hot air flow . Its new enlarged battery design means it provides 25% larger radiant surface than the previous Dragon 3 model and ensures faster air flow emission and increased chimney effect for better comfort.

Functions - The Dragon 4 heats the air faster than any traditional oil-filled radiator and creates a comfortable mixture of radiant and convected heat, providing 2 kW of total heat output with 3 switchable heat levels, a room thermostat which can be set to automatically regulate to the desired temperature and a 24 hour mechanical timer.
