All about Electric Showers:
Electric showers heat cold water directly, as and when you use them. Cold water simply travels into the unit which contains an element able to instantly heat water. As they are independent of the hot water supply, if your boiler fails you are still able to have a hot shower.
Aside from the generic advice regarding aesthetics and practicality, what are the important things that you need to know about when purchasing an electric shower?
Electric Showers vs. Power Showers:
As both can offer an invigorating water jet, many confuse electric showers with power showers; but this would certainly be a school-boy error as there are some key differences:
- Electric showers cannot create a powerful water jet on their own as the pressure at which the water is dispensed is dependent on the existing pressure of the system. Power showers, on the other hand, have the ability to increase the pressure of water so are essentially an electric shower with a pump.
- With an electric shower, only a cold water supply is required; whereas cold and hot supplies are both necessary for power showers. Electronic ones are, therefore, more economically viable as they only heat the amount of water which is required.
Consider A Thermostatic Electric Shower:
Thermostatic electric showers are perfect for family bathrooms as they have the ability to remember the water temperature you set; unlike conventional showers, they are able to keep temperatures constant and are not affected by the actions of others. So if a tap is turned on while you are showering, the temperature and pressure will remain unaffected.
They will either contain valves with dual controls, controlling both the water flow and water temperature, or a single control which is able to operate both in one fluid movement.
The Importance of KWs:
In order to function properly, an electric shower requires the correct amount of KWs. A KW is the unit used to measure electricity, with 1 KW being the equivalent of 1000 watts.
It is a common misconception that the higher the KW rating, the higher the water pressure will be. In fact, the rating only refers to the power of the heating element situated inside the shower. The advantage of a higher KW rating is, therefore, to heat the water faster and more efficiently at lower settings.
Which Fuse Will I Need?
It is also worth noting that each shower will require its own dedicated circuit, and the specific fuse required will depend on the KW rating: if the fuse is too low it will blow, but if it is too high it could burn out. To provide a little guidance, we have outlined the three most common types and their required fuse:
- 8.5KW showers require a 40 Amp fuse.
- 9.5KW showers require a 40/45 Amp fuse.
- 10.5KW showers require a 45 Amp fuse.
Installing a New Shower: Remember KW Differences:
When purchasing a new shower, it is important to check the KW rating of your existing shower as your new one may differ. If it does, you may need to replace your electric cables as failure to do so can result in the shower area becoming a fire hazard. If you are unsure what it is, we’d always recommend consulting a qualified electrician.
