Seasonal effects on electric showers

General 4 October 2016 Share this

During the colder months, we find there is an increase in calls from customers concerned they have to turn their shower up to a hotter setting to obtain the temperature they're used to showering at. However, this isn't necessarily indicative of a fault with their shower.

When purchasing electric showers, many people aren't aware that seasonal weather has an effect on the temperature and/or water performance of their shower. In particular, during the winter, you may notice that the temperature or flow rate (or both) of the water being emitted from your shower head drops.

To understand these effects, try to think of your electric shower as a kettle on the wall. Most electric showers have at least two heating elements, as well as three heating settings on a "heat selector" dial:

  • High - where both heating elements are used
  • Medium - where only one heating element is used
  • Low - where no heating elements are used

The first element (on the photo, it is the medium setting, but on some showers it is usually the second heat setting on the heat selector dial) heats it to half heat. Then when you turn the dial up to the second heat setting on the dial, it turns on the second element, therefore demanding full heat.

During the winter, the temperature of the water coming into your house is colder. As a result, the shower has to work harder, meaning that the water flow slows down to compensate for the drop in outside temperature. You will therefore have to turn the shower up, either by adjusting the heat selector to the highest setting or turning the temperature selector dial round towards red, in order to obtain your normal showering temperature.

The theory is the same in summer too. At that time of year, the temperature of the water coming into the house is naturally warmer, so you don't need to use as much power/heating. Usually turning the heat selector dial to medium should suffice to prevent getting too hot a shower. Plus, as the water isn't being heated for as long, the flow rate will increase as well, allowing for a slightly more powerful showering experience.

If, during the summer, you have your heat selector set to high and the shower is too hot or goes hot/cold, it is probably due to the heat selector being too high. Try turning the temperature setting further towards the blue and see if that makes a difference. If it doesn't, turn the heat setting down to medium and fine-tune the temperature on the temperature selector dial from there.
