Showerhead heaters are easy to install and use tankless devices that quickly heat water on demand. Most of them are flow-activated, and it will only do the heating when there is sufficient water flow. Typical systems have a pressure-controlled mechanical switch. When the inlet water has enough pressure, it pushes the switch contact that completes the circuit that energizes the heating coil.
As the cold water passes the compartment with the electric coil, the hot element will heat it. The hot water temperature is dependent on the volume of water and flow rate. If you open up a lot of water, the temperature does not go very high. However, if you open a small amount of water flow to just activate the heating coil, you may be able to reach a higher temperature.
As such, you need to determine the best point that gives you a comfortable temperature. Additionally, most shower head heaters have two or three settings that you can adjust using a mechanical switch on the device.
