I am using water heater brand is Eaga.
Seems like china brand? and very hot the water even under the condo's water tank pressure, no local product can compete so far from my experience. 
I might be the next one to die u see..

The sad news is, they left behind a 6 months old baby. Pray for the baby finding a good home.

If i am him i will hack the tiles. but how come it will be 2 meters long? i couldn't understand, by right at least you should decided the position of ur water heater, more or less 2 feet diff.

Because the pipe is from the top of ceiling until the heater

Ahh, can it be you already have rain shower with storage heater?

I don't think so...but just want to confirm how a centralised storage heater work? issit for every rain shower,there should be 2 pipes connected to a valve,then u can adjust the heat of the water (which in turn connected to valve to adjust how much hot water and how much cold water mix to rain shower) by turning the switch?

My house currently only have 1 pipe connecting to rain shower.

Don't need two pipe after the mixer, only one pipe after mixer. and depend what type of mixer use some come with one turning knob and piping conceal.

This is why I am angry with my developer,give me a nice shower rain on top of ceiling,but never give me the pipe for centralised water heater. Asking my reno sifu now to see how to do it with minimum hacking of tiles....

maybe got leh, do you see a man hole cover on your ceiling in your bathroom?
go up and take a look. Maybe there is a copper pipe there. The part that you can see usually very short length only. it wont be connected to anything.

or take a look at your controls for turning on the water. do you see a red and blue dot?

what's an instant water heater? is it those that are mount on the wall type?

Purchased Alpha Smart 18i from Perfect Lifestyle fair a week ago, and they have came for installation yesterday,this is the first time in my life that i am installing water heater (all the while,my parents refuse to install heater because worry of electricity leakage),and holy shit,they use a PVC pipe to connect the output of my original rain water shower output to the heater input, and now, I can see the whole PVC pipe naked on the tiles which is about 2 meter long.....

Oh my god,i really can't accept that after spent so much of money to renovate the house,and the ugly part appear in the toilet!!! Really learnt my lesson, anybody here got idea how to overcome this?? except drill hole and put the pipe inside, and redo the tiles??

you may change to useflexi hose and a water way instead like mine:
