  • After boiling the solution, allow it to sit overnight. Later empty the pot, check if there is limescale left.
  • You can consider cleaning the remaining limescale with baking soda and rag or repeat the procedure above until the tank is clean.

  • Pour the mixture into the dispenser and allow it to settle for a few hours.
  • After some hours, press the start button, and water will start to pour as you discard it.

Can You Get Sick from a Water Heater?

Water heaters are of great help at homes and allow you to heat bathing, cleaning, and washing water. These heaters mostly use tanks that store hot water until when needed. With the storage of water in large volumes and for a longer time, some problems may arise. Therefore, it becomes unsafe to consume this water due to the following reasons;

Excess sediment buildup

You may drink this water if the sediments are less. But with time, minerals build up as more water enters and leaves the tank. The deposits may also destroy the heating element and burn it away.  Therefore, it’s best to flush your tank regularly to clear away these particles.

Smelly or discolored water

If you fail to clean your tank, more dirt will accumulate, and bacteria start to grow. Bacteria can be risky to your health if you consume this water. These microorganisms also cause unpleasant smells due to the gases released when they die. Thus, always clean your water tank if you need to consume this water.

Water is too cold or extremely hot

Due to the thermostat settings, the water from the tank may have extreme temperatures. Too hot water can cause burns and again leads to high bills. On the other hand, sometimes this water may be too cold, especially if there is an issue with the heating element. So, always keep checking your water heater’s temperature.

For convenient and safe water heaters, consider the following;
