It's very simple. Each kwh rating on your electric heaters will cost your tariff kWh rate per hour. So, if your rate is 11p per kWh, your 1kW heater will cost 11p per hour to run, until such time as the 'stat cuts it out. Your 2kWh heater will cost 22p per hour, your 3kW heater 33p per hour, and so on. Every electrical device has a rating plate telling you how many watts it draws.No free lunch, and no free laptop0

Except it isn't as simple as that.

Electricity converts to heat at about 100% efficiency. (heat pumps excepted, where a COP of 3 or more is achieved) However, it depends on many factors, including the behaviour of the inhabitants, whether it is most cost-efficient to convert the electricity into convected or radiant heat, or a mixture of the two. It is very difficult to advise accurately without construction plans and an extensive questionnaire regarding personal habits etc.The most efficient system would probably be padded overalls heated by a battery pack. Unfortunately it tends to play havoc with your love-life in the colder months.0

Just don't mix up the polarity!
