In a lot of old countries, the heater is especially essential, because, in the winter's extreme low temperature, the heater is essential to provide the necessary heat for residents inside any building. Nonetheless, in Singapore, because of the perennial summer and high temperature, the heater is not going to be used as often as in countries with cold weather. Still, heaters can be very important for water heating in Singapore. In fact most people in Singapore prefer to shower with warm water instead of cold one. As a result, every household and also in some offices need heaters for showering and cleaning purposes. To wash oneself in the cold water even in such a hot country like Singapore is not an enjoyable experience. And a functional heater is thus essential to provide the enjoyment to people. Should the water heater shows signs of damage or wear and tear, water heater replacement
might be essential from time to time. This is to avoid safety hazards or damage of other appliances due to water heater failure.
