The weather is certainly starting to take a turn, as the temperature drops we find ourselves digging out the scarf and gloves. What you may not know is that the cold weather can effect on your electric, mixer and power showers.
Find out more about the seasonal effects and our recommended shower adjustments to help maintain your showering temperature during the colder months.
How do electric showers work?
Electric showers work very similar to the way in which an electric kettle does. Like a kettle, electric showers heat water using electrical heating elements. Most electric showers feature two heating elements which heat the water provided by the cold mains water supply .
Most electric showers have three heating settings:
- High – where both heating elements are used
- Eco – where only one heating element is used to minimise energy consumption
- Low – where no heating elements are used
The temperature delivered by the shower is then adjusted using the temperature dial which alters the flow rate of the cold mains water passing through the shower. The slower the flow rate- the warmer the shower. The faster the flow rate- the cooler the shower as the water passes over the heating elements faster and is therefore cooler.
What difference does the weather make?
During the winter months the temperature of the cold mains water supply is also colder. This means that in order to heat the water supplied from the cold mains water supply to a comfortable showering temperature, electric showers require the flow rate reduced in order to allow the water to heat up longer within the shower.
This is achieved by turning the temperature dial clockwise and thus reduce the flow of water.
How do you adjust your electric shower?
- Run the shower as you are making the adjustments so you can feel the temperature change.
Check the top dial of your shower is on the highest setting (the two heating elements working).
Reduce the flow through your shower by turning the bottom dial towards a warmer setting.
The Mira Advance ATL is the only electric shower that is perfect all year around. This fully thermostatic shower will be the same temperature setting summer and winter – but you will notice a drop in the flow rate. Using the High button will give you the best flow rate in the winter months.
Some showers, such as the Mira Elite QT, heats water from a cold stored supply. The supply is normally stored somewhere such as the loft, which can still be affected by colder weather. You will, therefore, still need to make adjustments to your temperature settings.
How to adjust your Mixer & Power Shower
If you have a mixer shower supplied by the cold mains, your shower will also be affected by the weather. You can adjust your shower by changing the water heating system to a winter setting, or refer to your installation and user guide and adjust the maximum temperature setting on the mixer control itself. We recommend that your boiler or hot water unvented cylinder is set to between 55-65˚C.
If you have a mixer shower or an all-in-one power shower supplied by a gravity-fed stored supply, then you might need to increase the maximum temperature setting on the mixer control. Check the hot water cylinder is between 55 – 65˚C.
