Too Hot or Cold: How Seasonal Weather Affects Your Shower

Read on and watch the video to find out more about how seasonal weather affects your shower and how you can alter the settings to get the perfect temperature year-round.

As the seasons change, the temperature of your incoming cold mains water supply will differ, being warmer in summer and cooler in winter. This can impact the temperature of your shower – especially electric showers, which heat water from the cold mains supply.

Electric showers are the most susceptible to seasonal temperature changes, so learn how to alter the settings to suit your preference year-round.

The temperature dial on electric showers alters the flow rate of the cold mains water passing through the tank. The slower the flow rate, the warmer the water because it has more time to heat as it passes over the elements. The faster the flow rate, the cooler the water because it has less time to heat as it passes over the elements.

Mixer, digital and power showers work similarly, combining water from your hot and cold supplies to create the perfect temperature. This means they are also susceptible to seasonal temperature changes.

If you have a mixer, digital or power shower supplied by the cold mains, it will be affected by the weather in the same ways electric models are (hotter in the summer, cooler in the winter).

You can increase the water temperature from your heating system by adjusting the boiler or cylinder thermostat to a higher setting. Refer to your user manual and adjust the maximum temperature setting on the mixer control if required. 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, you might need to increase the maximum temperature setting on the mixer control. Check the hot water cylinder is delivering between 55-65˚C.
