I got the one with rain shower, cost me around 550...The one without rain shower should be around your budget

Means can't turn off pump if you have good incoming water pressure or can't adjust the pump if you have lower pressure since it's fixed one.
If you live in condo you may just get a heater without pump.

typically condo will not have pressure problem, only landed? i live on 28th floor of a 38 floor building.

Yeah, usually condo won't have water pressure problem, unless for those very old type condo/apartment.

Typically condo water supply is pressurised, and after 20 yrs then pjpe start rusting if iron pipe on the inside, old 50c coin become ciggie size hole, and then they will change the building pipes (hopefully).

U can test w water hose and see if you can stop the water using ur thumbprint. Cannot stop means ok pressure.

thanks bro and sis, then any recommendations for DC non pump type?

Er.. that is going into special industrial equipment already. Have to see RS components

1.0 Generally all instant water heaters for home shower use work on AC power from TNB, SESB, and the other power company in S'wak.
1.1 These WH branch into pump and non-pump type.
1.2 for 3kw class heater with standard wiring this will work-lah.
1.3 for 4.8kw class heater ("highlands model") in short - this need special cables/wiring as it is very heavy appliance. Cannot use with standard developer wiring.

2.0 For with-pump model, there is sub category based on the pump type -
2.1 whether u want a "DC pump" for less noise
2.2 or "AC pump" maybe cheaper but this is more noisy.
2.3 Additional consideration whether there is pump pressure control, or its all automatic (no user adjustment possible)
2.4 Skip to user interface at 4.0

3.0 For non-pump type
3.1 there is NO pump inside.. so basically any non pump is the same.
3.2 Subcategory of non pump is mainly on the user interface

4.0 User interface - for me getting a WH it is better to get a push start button type like the Pana M series or Hitachi series. As those with water valve (to me) feels "cheap" since the 200 bucks model also same way of using.



5.0 Suruhanjaya Tenaga regulations say all WH circuits (wet floor places) need a 10mA RCD for your WH circuit.
5.1 This is pretty easy to install assuming the existing point is already ready.
5.2 Many people dieded because no 10mA RCD was fitted inside the DB box. Every few years, electrocution victim come out in the news.
5.3 The whole house RCD is kind of insensitive and will NOT protect you adequately, or even at all (as some are VERY insensitive) from current leakage of the WH.

An expensive WH without a proper 10mA RCD fitted is very dangerous.
A decent brand WH, with 10mA RCD is safer for everyone.

All,
Just for your information, the whole of klang valley there's only one certified installer recognized by Centon. And he is charging very expensive charges - RM450 for installation, then plus RM300 for the plaster ceiling cut and restore (he somewhat insist on using his own guy for the plaster ceiling).

The feedback from the centon/onsen was the water heater warranty would be voided if the heater was installed incorrectly, so if you are not using their recommended installer and if anything goes wrong then they can just say "oh it was not installed correctly" and void the warranty.

Installation charges depend on SoW. This is storage heater so it need more work on the power point (as compared to the developer point usually suited for instant WH); and 4mm² cable to be used, and copper cable price skyrocketed wef 2021APR. Plus depending on how many outlets it branch out to - as compared to instant WH in a site where all points are ready by developer: drill six holes, hook up water pipe, hook up power cable..

The plaster ceiling one if just cut and patch back cut line with stopping, fiber netting shouldn't be that expensive unless painting over is included as well?

I believe when Centon say "void warranty", it means that if anything wrong with the heater during warranty period, and u request for heater diagnostic test, when their technician check that heater is not faulty but is not working because of wrong installation, u will be charged for the diagnostic test (and fixing / spare parts needed to repair any damaged caused by the wrong installation). Once heater installation is corrected and any damages caused by wrong installation are fixed, heater warranty will be valid again. This is the same for all water heater brands.

An example that I have encountered before, my installer used an underspec-ed 1.5mm cable to install my Centon water heater. After using for a few weeks, the cable and terminal block (part of the water heater) burned due to the underspec-ed cable. Centon technician have to replace the terminal block and change the cable to a 2.5mm cable as well, and I have to pay for the Centon diagnostic test + spare part (terminal block) + cable, which I believe is completely fair since it is not Centon's fault. Centon also told me my warranty void for this house visit due to wrong installation, but is now valid back again because installation is now correctly. Of coz, I then seek compensation from the original installer who had screw up and use a 1.5mm cable to install my water heater.

I believe u r free to use any installers to install any water heater brands, just make sure they are installing it correctly by getting a certified installer (usually those that are recommended by electrical stores themselves or the Shopee / Lazada stores are good enough).

Am planning to install storage water heater for my condo (likely since developer already prepared hot and cold water piping, but not providing the tank).

The developer prepared the hot and cold water piping (to shower and basin), but not overflow pipe. Some owner had to resort to cut out 1 small hole at the plaster ceiling above the shower for the overflow pipe.

I wonder is there any idea or possible solution to route the pipe where it can be hidden or not so obvious? Maybe some of you is creative/have experience. Can I hack and let it drip to the vertical air well area?

Hi all,
I'm in dilemma to choose within these 2 models instant water heater..

If anyone has experience with any of these 2 models care to share their pro and cons?

Toshiba DSK38ES3MB-RS

Joven SL30IPRS

Why you shorlisted the two models ?

Toshiba because of the price point.. and joven because of the EELS function

thank you very much for this share !

If you are looking for instant water heater that comes with rain shower model, just saw on Shopee that CENTON just released a new model CENTON EcoSerene Rain Shower (4.2kW), only RM499 with DC Silent Pump + Rain Shower, or RM399 for no pump + Rain Shower.

Should be cheapest in the market, cheaper than Toshiba or Midea. One of the best-sellers on Shopee too, and reviews from buyer looks good with a 5 star average ratings.

this brand good? first time hearing it.. care to share your experience?

it has a stronger heater than the typical 3kW class. so if water pressure strong then this will be nice to use.

however as it takes 18.3A as per the rated power,
your wiring need to be up to code to support. using ciplak or fake wire will not have sufficient current carrying capacity to support well (undersized cable will heat up). Good quality 2.5mm² cable no problem.

any WH is just a fancy electric kettle. the most important life insurance is a properly fitted 10mA RCD at your DB box. one time payment saja no annual renewal premium.

I am using CENTON Serene Series, the premium version of this EcoSerene, so far very satisfied with it and hotter water compared to other water heater brands that I have used before. Centon Serene and EcoSerene comes in 4.2kW, while other brands are mostly 3.6kW or 3.8kW, so Centon water heaters are usually hotter compared to other brands (but don't expect huge difference in heat la), very good especially during rainy season where the water supply is colder than usual.

Centon, Alpha, Joven, the electrical store salesperson said the bosses of these 3 water heater brands are from the same family, so technology and reliability should be pretty similar. But at Shopee looks like Centon is the best selling ones amongst these 3 Malaysian brands, and most of the Centon Water Heaters are with 5 star ratings, very impressive ratings for electrical appliances.
