Seasonal Effects On Your Shower

Mira Recommends on adjusting your showering temperature

Blog
Monday 28th November 2016

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 to reduce the flow of water and the power dial turned to high to benefit from the maximum heat input from the elements.

How do you adjust your electric shower?

  1. Start the shower
  2. Check the top dial of your shower is on the highest setting (the two heating elements working).

  3. Gradually reduce the flow through your shower by turning the bottom dial towards a warmer setting.

  4. Wait for the water temperature at the showerhead to stabilise and check it is at a suitable showering temperature before using the shower

Some showers, such as the Mira Elite QT, heat 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 and power 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 increase the water temperature from your water heating system by adjusting the boiler or cylinder thermostat to a higher setting and if required also 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 deliver water 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 delivering between 55 – 65˚C.

If you need more information on how seasonal changes can affect your shower throughout the year watch our helpful animated film on adjusting your shower. Alternatively, you can speak to a member of our customer service team, visit our contact us page.

 

Only for mixer showers, particularly fitted on a combination boiler system. There may be times where the water flow through the boiler cannot be slowed sufficiently to deliver hot enough water. In this case a flow regulator can be fitted into the showerhead or hose to achieve this. Contact Mira Customer Services
