Keep in mind that electricity paid for a point of use, puts 100% of its heat into a room. It does not waste heat in ventilation, it does not waste heat, raising the temperature of pipes or water in pipes.
I used to have a large flat that was heated to 23 C by two small 500 watt bowl heaters controlled by a thermostat.
It was very cheap to keep warm.
Now I have radiators, a zoned system, insulation and it costs a fortune to keep warm.
Take a look at each option. Double glazing helps, being a flat thats on the first floor, where you gain heat from the surrounding flats helps. The location of the building, is it exposed to strong cold winds, all these things make a difference.
