All,
Came across a visit to a house with Centralised water heater. It uses of electrical combustion tank stored at roof and supply the hot water through another piping system from normal water.
Question is, does this kinds of system is expensive to maintain? Do we need to switch on the heater all time? Or only switch it on before using it? How about electric consumption ???
Thanks in advance
As of what installed in my house, there’s 4 water heater tank above my ceiling which requires me to switch it on 15 minutes before usage (I have a timer, set to switch on immediately during certain hours of the day and the water heater tank has it’s own current cut-off system), whereby the water will go through copper pipes to all my 7 bathrooms, kitchen and laundry room.

The disadvantages are there’s no instant hot water and if the tank is empty, the heating rod will be damaged. The tank will only be empty if there’s no water going in and hot water going out.
Damage in cost: cooper pipe, water heater tank
Advantage in visual: no visible pipe that usually associated with instant water heater
