They don't say specifically, but my guess is that they use a mineral oil is because it is cheap and non-toxic. There are also many synthetic diathermic heat transfer fluids that have better performance, but these are more expensive. Glycols are also used in some moderate temperature applications such as radiant heating systems in floors and walls, but I doubt they are used in something as hot as a space heater (the total power dissipated by a space heater may be less than a house radiant heating system, but the peak temperature of a space heater's internal electric heating wire is higher).
yes
An oil-filled heater such as the DeLonghi does not produce C02 - there is no combustion involved - an electric heating element inside a sealed metal housing transfers heat to encapsulated oil, which in turn heats up the entire radiator housing. The heated housing then transfers heat to the air in the room.\
No. I spoke with customer care representatives of two brands (Delonghi and Holmes) of electric oil-filled heaters, and both said that the oil will not freeze. I asked whether there would be any harm in leaving one of their radiators in a car for several days at below-freezing temperatures, and was assured that this would not be a problem.
They are safe to use in side just keep fabric away from it.
There are several places one can buy an oil filled radiator. Online retailers include Amazon and Delonghi. Retailers that offer both online and in store purchase options include Lowers and Walmart.

Sand is usually used.
Electric light bulbs are commonly filled with argon gas. The other ones could also be either helium, neon, nitrogen or krypton.
One can shop for affordable oil filled electric heaters from many different stores and retailers. Some examples of these stores include Target, ZORO Tools, and Frontgate.
A portable tank is available that can be filled from the stationary tank for trips outside the home.
On the ground if you've taken them by truck. Never fill them when they are in the bed of a truck.
Gasoline spills contaminate drinking water and harm aquatic life. When filling your boats portable gasoline tank, always fill the tank on the shore
