Nowadays, living conditions have improved, and we need to bathe in hot water, whether it is summer or winter. So after taking a shower, should we unplug the electric water heater or wall-hung boiler? After being reminded by the master electrician, we now know the answer. So should you pull the plug or not? Let's take a look.
Often, when using a water heater or wall-hung boiler for bathing, many of us have a misconception.
First of all, let's understand how an electric water heater or wall-hung boiler works. The working principle of a water heater is to supply hot water by constantly heating the water stored inside. When the water temperature drops below a certain set temperature, the water heater will automatically heat up. Therefore, even if we continue to use hot water in the bath, the water heater will still continue to heat the reserve water inside, that is, it will be in working condition all the time.
Whereas, when the water heater works, the water inside has a certain current. If the water heater in your home has been in use for a long time, there may be an aging circuit problem. Once an electric current is passed through the water and reaches us, it is prone to the risk of electric shock.
There have been many news reports of frequent electric shocks due to long-term use or leakage of water heaters. Therefore, it is best to unplug the water heater in your home before or after bathing to ensure safety.
There are many types of water heaters. For example, when many migrant workers live in rented houses, the landlord may buy some water heaters that are not big brands or miscellaneous brands in order to save costs. For the water heater used in this case, we must unplug it.
If it is a brand new electric water heater installed in a newly renovated house, the water heater at that time is safer, and there is no need to unplug it when we take a shower. However, any electrical appliance is dangerous and has a useful life. For example, a water heater needs to be replaced with a new one after seven or eight years of use.
Finally, it is recommended that whether you are using a new or old water heater in your home, it is safest to unplug it when taking a bath. Similarly, the same is true for wall-hung boilers, which are unplugged after each use.
If the plug is kept plugged in, then when using water during the day, if you accidentally turn on the hot water switch, the wall-hung boiler will always work, which will be a huge waste of electricity. Therefore, even when using water during the day, we should unplug the wall-hung boiler, so that we can save a lot of electricity bills over the course of the year.
In addition, when the wall-hung boiler is no longer in use, not only should the plug be unplugged, but the gas switch should be turned off. Because if a gas leak occurs, the consequences are very dangerous.
