Have you ever used an electric shower? For a lot of Americans, the answer is no. Electric showers are relatively uncommon in homes throughout the Western world, but pop up increasingly frequently in developing world homes or situations where water pressure, power or water heating is unreliable. Especially popular in South East Asia, the electric shower is a standard fitting in Asian bathrooms, cleaning facilities or public fitness centers.
Why are they so popular? There are several reasons. Firstly, the water pressure in developing countries often isn’t superb. While the United States is blessed with high quality drainage and water systems — at least in major centers — many countries aren’t. When water pressure is low, showering is difficult, and certainly uncomfortable. Electric showers get rid of this problem by building water pressure within the unit itself, boosting the heat, and then releasing the water. In short, an electric power shower will hold the water while pressure builds, and release it in a greater pressure than before. 
These electric shower heads are also highly useful for houses that don’t feature a hot water tank of cylinder. If hot water is at a premium in your residence, these electric showers could ease the problems. By heating the water after it’s left the home’s piping system, electric showers eliminate the need for a large hot water tank. Perfect if you’re in a populated house, these electric shower systems can eliminate fights about hot water usage, boost your water pressure, and keep everyone happy with their shower!
Many major manufacturers offer electric showers, with Triton electric showers proving especially popular. While there are subtle differences between different brands, all seem to work in the same basic fashion. Firstly, there is a temperature knob, which controls — not surprisingly — the water temperature. Secondly, there is a water pressure knob, which can control the water pressure. Some poor electric shower units will only work at full heating capacity if the pressure knob is at a low level, however most units should provide full heat at all water pressures. Finally, there’s the standard shower controls — spray type, removable shower head and everything else.
While electric showers aren’t a common bathroom find in the United States, anyone involved in international travel will have to use one at some point. Remember those operation instructions, experiment with different pressure levels, and enjoy your warm electric shower!
