Does putting on second switch mean it will use twice the electricity?

It depends on the design - e.g. one switch could control 1000W, the other 500W, giving the options of 500W, 1000W or 1500W depending on the settings used.

Check the specification/manual to find out what applies to your one.

Two units an hour? A "unit" is a kilowatt hour, so it will use exactly 1.5 of those. At c 20p an hour, that is £4.80 a day or about £150 a month. Depending on the room it's in, you could lose more than that out of a poorly insulated room, so you'd never feel any benefit.

This is the point, really. There's nothing to say that a 1.5 kw heater will actually be capable of heating the room at all. What about if it actually takes two of them to heat it?

Put the dimensions of the room into an online calculator - https://www.bestheating.com/btu-calculator?

For a living room, 4m x 4m with 4m² of window, ~1500W should be sufficient. Solar gains during the daytime will reduce the heat requirement, as will the presence of any occupants. Total energy consumption for a typical day will be governed by maximum room temperature, external temperature, and the quality of insulation (if any).

...This product is only suitable for well insulated spaces or occasional use...

I just bought an oil fill radiator from Toolstation and a search for the above brought me here. The problem I'm experiencing is that the heater has been placed in a conservatory in an uninsuated space so cold that it has extended use. The consequence is that the it keeps tripping the internal over temperature cutout. The answer to your question is therefore, the appliance is not suitable for continuous use and a well insulated space will mitigate this. Another issue is that when the heater was turned upside down to attach the feet it was gurgling so air was present. In all likehood the fins are airlocked preventing convection cooling. Needless to say, its going back as faulty.
