FAQs About The Storage Water Heaters in Singapore
How storage water heaters work is that it allows you to heat up the water in the tank first and it will store the hot water until you want to take a shower. This reduces the risk of electricity leakage and makes a storage water heater safe to use in Singapore. Unlike the instant water heaters, you get to enjoy a consistent flow of water with the same temperature while bathing. If you want it hot, the water flow will not suddenly turn cold. What I personally like about the storage water heater is that you only need 1 of this appliance to supply water to places like the bathroom, wash basin and even washing machine.
According to local market price to install water heaters in Singapore, it ranges between SGD 50 and SGD 200. Rather than hiring an external plumber to install your water heater for you, I would recommend checking with the brand that you bought from on whether they provide any in-house installation services. Some models may require you to bury the hot water pipes in the wall may be an additional SGD 200 to $300 cost to the overall installation fees.
Whether or not instant water heater consumes more electricity than the storage water heater is debatable as it fully depends on the frequency of usage. Generally, instant water heaters tend to cost less as they only consume electrical energy when in use. Unlike the storage water heater, a fix electricity is used to heat up the whole barrel of water.
Just imagine if you own a 25L storage water heater, it is impossible for one person to use that much amount of water for bathing. Unless there are several users bathing one after another continuously. As a result, the unused hot water in the storage tank will incur higher water and electricity bills. To put it simply, before you take a shower, you must first preheat the water in the heater. If you somehow exceed the amount of hot water, you will be forced to bathe in cold water.
On the other hand, a large family using the instant water heater will definitely use much more electricity because the frequency for bathing will be high.

If your home is completely powered off, this indicates that the leakage protection is functioning normally. If not, call an electrician immediately for repair.
