There are several reasons why an electric shower would run cold. While most of the reasons have to do with problems with the functioning of the shower, some are just not problems at all. If your electric shower is running cold, you are not alone. Many people experience the same problem, and that is why this article is relevant. We are here to share some insights into why this problem occurs and whether you can solve it by yourself or with the help of a technician.
We shall address the two main causes of electric showers running cold, and they include:
This is the main culprit responsible for electric showers running cold. It happens a lot in newer buildings as well as the top floors in a multi-storied building. It is also possible for water pressure to reduce significantly when other people are using the same water supply at the same time. If you are not living upstairs, but you still experience the same problem, then there are high chances that the water company supplying you with water has reduced the pressure temporarily to work on it. If that is the case, you can either wait until the water company restores the pressure of the water or find a new main supplier.
Hard water contains mineral deposits that usually leave behind limescale, which damages appliances such as water heaters and water pipes. It is possible that your heat canister has been scaled up inside by the limescale in the water. This restricts the flow of water into the electric shower. If this is the case, you are advised to descale the heat canister using a descaling agent such as citric acid. It is, however, worth noting that this problem requires the services of a professional plumber to solve because it involves disconnecting the incoming cold water pipe. Alternatively, you can decide to replace the shower with a new one and ensure that you form a habit of descaling on a regular basis.
Your electric shower could be running cold water because it has a small gauze filter at the water inlet point.
Although not a common cause of electric showers running cold, it is a possibility and the only way to find out if it is the cause is by checking the shower for some debris that could be blocking the flow of water.
In summary, it is possible for your electric shower to run cold water and this happens because of a reduction in the pressure of water coming into the shower. This could be because of a situation in which the demand for water is higher than the supply or the heat canister in your electric shower is scaled up. Solving this issue requires you to seek the services of a plumber or change the water supply company to one that supplies water at high pressure. Chances are that it could well be just the electric shower it's self. if the plumber says to replace it, we have provided a list of every best electric shower on the market for your convenience.
