Domestic electric fires

Electric heaters are almost inherently 100% efficient at converting electricity into heat and always have been. If it registers 2kW load on the meter, it will be producing 2kW of heat. The difference between one heater and another is in how the heat is distributed, e.g. a radiant heater heats the people and objects at which it is aimed, while a fanheater heats the air, etc.

For any particular radiant heater such as your Dimplex, different elements could theoretically have different dispersion patterns that focus the heat more or less accurately where you want it. However, 'aftermarket replacements' are normally intended to meet the original maker's spec as closely as possible and may be from the same production, (although some aftermarket parts are second-grade that the manufacturer rejected, or copies made with cheaper materials).

The way to improve efficiency in using electricity for heating is to ditch the elements and use the electricity to power a heat pump. Use it to move heat that already exists, rather than make new heat! The cosy glow you can do with LEDS...
