If absolutely no water, should have check water supply and piping firtst

Hi everyone, well finally my Alpha instant water heater died in a way no water came out from the machine even with pump is on and I suspect sediment collection within the machine eventhough I already installed dual stage filtering system in house.

Don't wanna play a fool as it's been 5 years since I installed this and my toddler showers in this shower.

Recommend me one so later I go buy? Thanks!

Also I have the rain shower attachment from alpha if I buy another brand this will still fit my current rain shower attachment?

Repair = fix old problem + cheaper

Saw this in another thread. Got any spesific model?

Joven ,Panasonic this 2 brand won't disappoint

Yep dissembled every pipe and thought it was a main pipe issue. Nope still ada water. There's something stuck within the machine itself

Landed apartment condo? If condo u water come from top floor no need to get with pump. Panasonic 300RM will do edi. Easy to install n use.

okay Panasonic it is then!

Read so many electrocution stories. Abit scared dy. Better replace. What's 900myr over my son's life u know what I mean?

Alright thanks brothers. Panasonic it is. Weird no one mentioned alpha even in the other threads.

It's not well known?

Landed bro but no entire house pump so sometimes water will be very low

If electrocution is your concern, please check your DB to see if you have 10mA RCCB installed for every heater. Else, it doesn't matter which SIRIM certified brand you choose as the risk of upcar is still high.

NO CIRCUIT BREAKER
Mr Goh also testified that the household’s electrical circuit comprised two wiring systems: An older system installed in 1971, and a newer system installed when the flat underwent the Housing and Development Board’s (HDB) Main Upgrading Programme completed in 2003.

As part of the HDB upgrading, a residual current circuit breaker (RCCB) was installed for the newer wiring system. The RCCB would trip the system and cut off the current when an earth leakage was detected.

The water heater drew electricity from the older wiring system, which was not protected by the RCCB as there was no such requirement at the time the system was installed, said Mr Goh.

He said that if the RCCB had been installed in such a way that it protected the household’s entire circuitry, it would have detected the earth leakage during the incident, tripped and cut off the current.

Son can make new anytime & its fun, 900 so hard to find now

Get one of the Schneider RCBO and install in your fuse box. Test it monthly.

the new model looks cool. But if you dont need so advance atas can try last year model.

Iinm, most shops only sell 25A 10mA Sneider RCBO. Supposing he's using 2.5mm² wires, will there high risk of wiring overheat especially if the wires are old?

Think 2.5mm² is considered too small for water heaters? They're rated at about 20A. If you use at maximum temperature, I think the wires will overheat.

25A is the maximum current but a 10mA leakage should trigger the trip.

U install yr self ke? Senheng provides installation for rm95 in case u interested

installed myself liau hahaha

Centon. Never go wrong

easy ke. i dont dare change mine 

Centon  have built in RCD  stated in the specs.. 

pump booster also stated 4.5X

can try  i guess.

Easy if 1-1 swap given existing water and power points
RCD or ELCB? 

2.5mm² isn't too small. I checked with an M&E consultant. Continuous current should not exceed 20A which is within the spec of most water heaters. Plus, if paired with 20A mcb/rcbo, it protects against overcurrent.

There are 2 issues here - over current and current leakage. A 25A overcurrent protection for 2.5mm² wires looks unsafe to me, regardless of its sensitivity.

okay Panasonic it is then!

Actually another sub-issue, DB box no space to put in a 2-module width RCD per WH circuit..

2.5mmsq cannot pair with 25A OCPD. it need a 20A MCB limiter.

Easy if 1-1 swap given existing water and power points
RCD or ELCB? 

it's very easy like changing the three pin plug. As long you make sure everything is secure

Next time im gonna try..

Centon  have built in RCD  stated in the specs.. 

pump booster also stated 4.5X

can try  i guess.

yes  its easy  to swap  1 to 1 .  open cover and  disconnect the  3  lines  L N E .  but ,,

But first  you need to know  how  the power  flow into the WH  from DB box. 
if there is a plug  point  then pull  of that plug  cable connect. to remove power .
or if it comes direct  from DB box ...  then trip off the MCB  . use a meter to confirm no 240V power  at the WH live .

last is  if you dont know how the power flow .. then  trip the main RCB  , then  whole house no power .
do this during daylight time and keep a touch handy .
This method also good  cos you test your RCB    still functional or not. 

the specs on Centon website say RCD  . 
Sirim approved...  
i  just quote what s on the specs.  dont know  if true or not.

5 years I would change. Better be safe than sorry.

Panasonic ftw.

Panasonic
with push start model
without LCD nonsense

Make sure WH circuit at DB box has 10mA RCD fitted.

I would never trust joven

Why

Either joven or pana. I normally choose which one has discount between this 2. The rest can use at your own risk.

A friend that work as technician for many budget hotel told me Joven is the most durable among all brands

U install yr self ke? Senheng provides installation for rm95 in case u interested

I'll go Rinai gas powered water heater.
So canggih

Either joven or pana. I normally choose which one has discount between this 2. The rest can use at your own risk.

Why

Senheng so cheap installation?
Lasr time i buy from a quite big electrical store at johor.
They external technician that linked with the store charge me RM 200.

9 years ago
.......
2 units install

If you open the both pana and joven casing, compare it's Internal components side by side. Pana seem much more robust with better internal waterproofing.

How to check this

Look inside the DB box
See the bigger blocks with test button?

For every water heater:
You need to have one big block with test button that:
a) cuts off ONLY the water heater when Test is pressed (NOT the whole house) AND
b) is rated at 10mA (0.01A).




And why do you need this protection?
a) It's the law - https://www.st.gov.my/en/contents/publicati...r%20Systems.pdf
b) Funerals are expensive

Most of the modern hse have this built in right

Ask electrician, pasang RCBO - it's more specific for water heater application.
