The comfort of a warm or hot shower is fresh every morning. This comfort is available when the water heating system is running smoothly. You might not feel so good about taking a bath the day when your heating system fails. Hot water maintenance should be done regularly to ensure the hot water is there for you every morning.

Maintaining an electrical water heating system is not that hard. You can call a plumber to do the maintenance for you though there are some tasks you might do yourself. Here are the main tasks to do;

Clean the tank

As the tank is used, there are sediments that accumulate slowly. There will be more sediment if the water is hard as minerals solidify in the clean. Rust and other impurities also accumulate in the tank. To clean the tank it has to be drained. Power is disconnected from the tank and then the drainage valve is opened. The dirt and sediment will flow out. Rinse the tank until clear water flows out. The frequency of cleaning your tank depends on its use and the purity of water in your area.

Check the temperature and pressure valve

The temperature and pressure valve is there to prevent the risks that can arise if the tank is exposed to too much pressure or the temperature is too elevated. The valve should let water out when it is opened and keep the water in when it is closed. If it leaks or it does not let water through when it should, it is time to replace it.

Check the filter

The filter keeps unwanted solids and dust out of your tank. It can become dirty and clogged with time. If you clean the filter, it will work fine. If it has become weak and shows signs of tearing you need to buy a replacement.

Check the sacrificial anode

Your plumber will open the tank and remove the sacrificial anode rod. Your plumber will ask you to buy a replacement if the rod is corroded to a certain extent or coated with calcium.


If your water heating system is tank less, scales will form on it. Scales make the heater less efficient and you will pay greater power bills. This is why you need them removed. Usually, there are manufacturer instructions on how the heater should be cleaned and what cleaning agents should be used.

Check the pipes

The pipes are not a source of concern as long as they do not leak and they are well insulated. If they need insulation your plumber will insulate them or ask you to buy insulated pipes.
