I am personally using this CENTON Neptune Storage Water Heater, bought from this website - https://www.onsen.my/products/centon-neptune-series. Apparently according to the installer, Centon storage tank is using enamel-coated tank, a newer tank technology with longer lasting leak resistance tank compared to older and more expensive stainless steel tank like Joven and Elton.

Using it for half a year already, use it a lot since WFH since MCO. Very reliable with constant hot water! Recommended ~

Around 15-20 mins from cold weather? But I don't switch the main power supply off, so my water is always hot. The thermostat is smart enough to cut off power supply when heated fully and only start heating when temperature is low, hence no significant increase in electricity bill.

Insulation is good. Once I heated it to full, and turn off the main power supply. The next day water is still hot.
