Electric Shower Head Heater

An electric shower head is a combined Heater/Shower head all in one unit, giving the user an endless amount of hot showers that can be used in any type of shower situation. It heats ambient-temperature water to a comfortable shower temperature as it is coming out the shower head. This means you don’t need to keep a tank of water hot just so you can take a shower. Or, if you live in a cooler climate, you don’t have to keep your water as hot for other uses.

A comfortable shower temperature is usually slightly warmer than body temperature – about 38 to 42C, or 100 to 108F. If you’re a devoted energy conserver, there aren’t a lot of other household hot water uses that require that hot a temperature. In fact you can do pretty much everything else in cold water, including laundry, dishes, filling the mop bucket, even running your automatic dishwasher (which, if ENERGY STAR rated, has its own built-in heater, although not all of them can handle starting from cold water). The only exception would be a bath, but if you can live without the occasional hot bath, you can cut your hot water bill to almost zero with an electric shower water heater.

Issues with Electric Shower Heads

There are two main problems with electric shower heads: temperature and safety.

The temperature out of the shower head depends on the speed of water flow, the temperature of the incoming water, and the available current. So there is no way to consistently get the same temperature each time you shower, unless your water pressure and voltage are constant, and you can memorize exactly how much to open the shower spigot.

Because electric shower heads are electrical devices they carry some risk of electric shock if installed incorrectly. Use these guidelines:

  • Make sure the model you purchase is certified for use in your jurisdiction. In the US and Canada this means it must be certified by either Underwriters Laboratory (UL), or the Canadian Standards Association (CSA). Either certification is acceptable for either country, and both are recognized in a wide range of other countries. Don’t install something that isn’t certified – you’re increasing your risk of injury and you may be buying a poor-quality product.
  • No wires should be exposed.
  • The wiring must be properly grounded
  • The circuit must be a dedicated circuit with the appropriate amperage. Most of these showers require a 30 or 40 amp circuit. (They are energy hogs for the few minutes they’re on – but they’re hardly ever on!) If you don’t have them on a high enough circuit you may keep blowing the circuit, which is not a fun thing to have happen when you’re covered in shampoo and soap and the water goes permanently cold.
  • The weight of the shower head heater element, and the fact that the shower head often extends out some distance from the wall (because many of these electric shower heads project straight down, not at an angle), means the shower head may need to be supported by more than the pipe coming out of the wall. Laundry wire or cabling connecting the shower head-end of the water pipe to points above on the wall or ceiling is usually used. You don’t want a running shower head crashing down on you as you’re showering!
