As a bathroom device, the heated toilet seat bidet sits in the middle of most household energy budgets. The number that moves your bill is total run time, so the usage hours in the calculator above matter as much as the wattage.
At 400 watts, the heated toilet seat bidet is a low-power device, so its cost per hour is small. The annual total only becomes meaningful if it runs for many hours a day — which is exactly why long-running low-wattage devices are easy to overlook on a bill.
Over a full year this heated toilet seat bidet uses about 584 kWh of electricity and is responsible for roughly 233.6 kg of CO₂ emissions on an average grid. Because it runs more or less year-round, even a small reduction in daily use carries straight through to a lower annual total.
To put the draw in everyday terms, one hour of running this heated toilet seat bidet uses about as much electricity as charging a smartphone 33 times. It is a rough comparison, but it makes an abstract wattage figure easier to picture.
If this heated toilet seat bidet is one you use daily, even small efficiency gains compound. Cutting its usage or wattage by 20% would save around $19.86 every year — money that an efficient replacement can recover over its lifetime.
