It doesn’t even use 3kWh per hour, since a stove’s peak usage is 3kW, and its average is much lower than this. Their price they give for running an oven is much lower than 3kW continuous too. Their table at the bottom also appears to show prices per year, but kWh figures per… not year. Per month perhaps? The stove is listed at 21kWh which is suspiciously close to 3kW * 7h, which would make it a weekly figure, but that’s also clearly not the figure they’re using to get their annual price.
