Under sink instant hot water tap usage

Here’s mine. About 750W, but it’s not on all the time. It has a thermostat, so it’s on maybe 2 min per hour.

The trends section tells me that it uses about 18.1kWh/month. Divide that down to hours and it’s about 25Wh/h. Same as leaving a 25W lightbulb on all the time. Or 40% of a 60W lightbulb left on all the time.
