thanks for the idea

In fact, the heating is sufficient from the instant heater. it is hot enough.

I understand your statement regarding the water flow speed vs the power to heat up the water.

I bought this model eventually, got a good deal on Lazada.
http://toshiba.com.my/waterheater/dsk38es3mb.html rain shower model.

High five I got this rain shower model too. Yet to install though

Cool. Good looking as well. I got it for RM 574, couldn’t resist it as other sellers are selling more expensive and with postage fees.

It was around 529 last year November. Got it during the 11.11 sales with bank voucher hehe

Good deal! Hopefully it works well later.

Yeah I am installing it pretty soon.

Hope the water pressure and all is all right.

i am looking at hydro one and Seers tank water heater with their own patented heating element. any other similar brand i should take a look?

Those are premium ones with their proprietary technology, very pricey.

For standard storage water heaters, u can check out the 2 market leaders:
- CENTON (for newer enamel-coated tank technology, cheaper too), or
- JOVEN (for older stainless steel tank technology, slightly more pricey).

Common brands in the market for storage heater :

Joven, Elton, Centon, Seers, Hydro One, Pecol, Beebest, Midea, Meru, Alpha ...

Points you need to take note are -

- your incoming water pressure
- what size of the storage tank
- power rating of the heater
- heating time to reach 60 deg C

Happy exploring

Also inner tank type. I suggest to go for newer enamel-coated tank technology (CENTON, MIDEA, XIAOMI, BEEBEST), rather than the older stainless steel technology (JOVEN, ALPHA, ELTON, PECOL).

Any recommendations for installing instant water heater? Ady have socket provided

dont use socket.

should always direct connect from 20 amp switch

Socket is against regulations (ref Suruhanjaya Tenaga) strongly discouraged because of the propensity of loose connection (=causes fires) and underrated (=causes fires) for any WH sold nowadays UNLESS its a 32A commando plug with proper IP rating.



Because any socket of 13A, 15A round plug is UNDERSIZED for a 3600W heater (3600/230 = 15.65A).

Plus the PE (earth) is by law (ref Suruhanjaya Tenaga regulation) need to be a direct connection (i.e. direct flight from the DB box into WH; with zero layby zero stopping zero refuelling).



Last but not least make sure you have a 10mA RCD fitted for the water heater circuit.
Also another statutory requirement.

Oh I see, got it, any professional sifu( that is not so costly to install 2 units) to recommend for the installation? The current socket is just normal 13A placed on top, so need to do modifications like mentioned above

A qualified electrician will be your best bet.
I installed myself, since developer already provided the point as a wire sticking out.

If you know what you are doing (since there is a socket there)
Test w test pen before starting to confirm the test pen works
Turn off the whole DB box, everything off.
Test with test pen again to confirm every wire is off.
Test again to be 100% sure.

check the cable is at least 2.5mm². If it is 1.5mm² your cables are undersized and cannot be used and you should call an electrician to install properly sized cabling from DB box.

Remove the 13A socket
Install this https://shopee.com.my/product/94486452/7647...38-1618845770.9 in place of the socket that you just dismantled.
The other end of the centon connector wire goes into the WH unit.

If u don't want the hassle of covering the existing socket with plaster / cement, you can just replaced the plug and socket with CENTON Splash-Proof Water Heater Connector, u can easily find them on Shopee / Lazada. SIRIM approved.

Also, this CENTON Connector comes together with a 1 meter 4mm diameter cable from Fajar. Take note that no SIRIM-approved water heater brands (that I am aware of) comes with cable or 3-pin plug (for reasons stated by a few members above, because it is not allowed by SIRIM), so your installer have to supply a cable to connect your water heater to the power source. Might as well just get this CENTON Connector.

Any water heater have a powerful pump? Because I've built in rain shower, scare it the pump not powerful enough no syok.. lol

Alright guess I will buy that one, but I have no experience in installing the water heater(afraid not enough tools), if I bought the socket, anyone can provide the drilling service ?

Technically with that Centon connector device we've cleared the electrical part.

For the physical installation most water heaters just need 4 holes for wall plugs..and another 2 holes for the shower head holder

Drilling wise covered in steps 2A-2C below. Pretty simple job if you have a drill.

For the plumbing.. if there is a water point for it that can be connected using flexihose then will be easier.. i.e. if existing is a screw fitting for tap, use a PVC nipple convert to male thread then just screw on flexihose (Hokah brand recommended and it comes in many lengths in 6" step - (ie 6/12/18/24/30 inches and up) according to ur needs.

Roughly these are the steps required
1-First need to mark the holes where to drill using the WH shell (the back part) itself as a reference. Make sure to avoid water pipe (anywhere vertically from water tap or mixer tap etc).
2A- Assuming your bathroom is tiled - need the bosch tile bit to scrape thru the tile slowly (like 5 mins or more) WITHOUT hammer mode - after gone thru already can use normal masonry bit on hammer mode
2B-If the mounting location is untiled (pure brickwall) then just hammer thru directly for the wall plug holes
2C-Shower head holder (can do this last if u need to think how high)
3-Install the WH shell
4-Connect wiring
5-Install WH front cover
6-Connect input piping and output to shower head

For recommendation.. also need your location boss, coz if we recommend KL folks and you're in Penang or JB, will be impractical
