1 watt-hour = 3.412 BTUs. Note the time component. So, if the element is rated at 1250 watts and is getting the rated voltage and operates for an hour, it will produce about 4250 BTUs. Actual BTUs produced will depend on how much time the element is switched on, which is typically controlled by a thermostat.
Many electric water heaters come with two elements, so note whether ratings shown are per element or total.
