Fuel Burning Heater

Hello, just got a 2004 Freelander TD4 HSE Auto with an FBH. Is there a way of turning it off. I thought it only worked when the temperature is less than 5 degrees? But it is warmer than that today and it comes on. It is noisy and smelly and presumably uses diesel. Is that correct?
Thanks for your help.
