Our bidet doesn’t have a tank and plugs into the 110 wall socket. The water supply is the cold water line that also supplies the toilet. After the first squirt the water is warm, depending on how you set the temperature. No hot water line needed.I don’t know how they could not have a tank. Any tankless water heater has some warm up period and a 110v source is pretty limited in how much water it could heat on demand. The whole house tankless heaters ( which I don’t really like) are like 200,000 btus or more.
