Edit:
Many thanks for your input everyone!
Just to clarify, I don’t want to take into account the method of generating electricity or shipping it to the home, or the relative costs of gas and electricity. I just want to look at the heater itself! i.e. does 1500W of input into a heater produce 1500W of heat, for example? Or are there other losses I haven’t thought of. Heat pumps are off-topic.

Not only is that (pretty much true), that means that if you have a 1500 watt heater or cooking appliance from a long time ago, it’s just as efficient as anything you can buy today.
So if you dig the style of 1979 Crock Pots or space heaters, you don’t have to worry that the newest technology would save energy, like with other appliances, motors, etc.
They are, they are just very expensive at what they do. At least in Belgium electricity prices are 3x higher than gas prices (per kWh). So your 100% electric heater is still 3x more expensive than the 98% efficient gas condensation heater. For heat pumps it more or less equals out, because they are 3-500% efficient if properly tuned because they move energy from outside to inside rather than just generating it.
