Electric shower heaters: this article explains the operating characteristics of electric shower heaters, also called instant water heaters or "on demand" water heaters for point of use at shower heads.

An instant hot water point of use system like the shower heaters we show here are a very different approach to making hot water for bathing than the tankless water heaters discussed above. These electric shower heads work where the incoming water temperature is pretty high to start and where the water flow rate is modest.
Electric shower water heaters are typically used where a central hot water heater is not installed. The heater is installed directly on the shower water piping at the location where a conventional shower head would otherwise be found.
Frequently Asked Questions (FAQs) about point of use electric shower heaters for making hot water
Question: how do I choose & set voltage for an electric shower heater?
I want to buy one does products but I don't know how many volt it - Elid Barahona 11/5/11
From an anonymous reader:
For Elid Barahona, Answer is: The Duromatic Electrical Instantaneous water heater is powered by 120 volts.
We add that the voltage choices (120V or 240V) depend on
- what voltage you have at the building (in the U.S. usually 240V but certainly not everywhere)
- choice to spend a little more on wiring or on the device to save on hot water heating costs (240V is generally more efficient)
