Hi there ozak,
I bought my unit also yesterday and wikl be installing today.
You mind sharing how much you bought it for?
Got it at rm750 without installation from a bath and kitchen shop in shah alam.
Agree with you,Really tired looking around for this particular model
Install it yesterday. Take about 2hr. Running very silent compare to the old 1.
Noise level about 55db at max pump running. The shower head flow is not strong as those big type. So if you looking for a strong flow, you will be dissapointed.
The cost:
1) Heater - RM720
2) Plumbing parts - RM5
3) Labour - Free
Here the step by step for those like to DIY.
Time to change the old heater after use for 7yrs. Still run perfectly without any problem. Just change for the safety reason.

Here the new
Rinnai heater with pump.

The internal part. Pump at the right, heater left, pump controller on top the pump, heater controller ontop the heater and the connection at the top right.

The diameter of the shower head is 7". Not that big consider the flow is not strong. You won't get a quick shower with this. Use the handheld for stronger flow.

First of all, swicth ON the heater.

Press the test to check the RCD function. Also as switch OFF the heater.

Use multitester to double check. After makesure no power, Switch OFF the heater Switch.

Takeout the wire and tape it with pvc tape. Close the stop cock to the bathroom water. Takeout the inlet piping. Now the old heater can be takeout completely.


Measure the height according to the manual. In this case around 1200mm. Mark and drill a new hole. Screw the heater to the wall.

Continue.......
