Guys, I guess the water heater brand is not a big issue... Because I know how to install it myself, without asking technician to do it. Actually it is very simple, and not dangerous as what you think.

The most easiest yet important part is, you have to make sure your Earth connector (green) is always right to connect to the logic board inside the water heater. If short circuit is happened, first, your fuse will break, the rest part of the leaked electricity will flow to Earth, hence to decrease the chance to get shock. (Correct me if I were wrong)

The problem here is, the victim get shocked is probably, the water heater is centralized, means it is hidden inside the rooftop, and the wire might be cut off by mouse or cockroaches.. when the water is leaked, then the person will get shocked without wearing rubber slippers..

So what I know is, most of the high end condos in Mont Kiara are providing centralized water heater, gas pipe and also air-conds(some).. When the condo gets old, the tenants might face these problems..

Anyway... just becareful.. 2 cents here
