Water heater electricity cost in United Arab Emirates
Electric water-heating cost depends on element power, storage losses, household demand, and the DEWA consumption slab occupied by the whole property.
Use the marginal slab including the current fuel surcharge and VAT rather than the first-slab reference when household usage is higher.
Use the marginal slab rate plus the current fuel surcharge shown by your electricity authority, expressed in AED per kWh. Account for VAT if it is not already included.
