any recommendation , visited to shop ,most of the shop introduce midea and deka ,but for my self ,i more prefer on panasonic and joven but when i ask about this 2 brand ,they told me not good ,but how can midea and deka better than panasonic and joven heater ,end up ,i decided not to buy and come here and ask


i dun mind pay extra for a better water heater ,safety first

Just get the Panasonic.

Been using Panasonic, Joven and Alpha water heaters.
For Panasonic, the push start button can't last 3 years.
So I changed to Joven, used it for 7 years without any problem.
Retired the problem free Joven after 7 years due to my personal safety standard and changed to Alpha 18e (no pump) because of the new safety feature with smart auto self-test on the internal curcuit to check if there is any leakage on all electric components & parts and line fault indicator. But one very important parameter that I overlooked on the Alpha is the minimum water pressure of 20kPa. If more than 2 water taps running at the same time, heater cut off too easily due to not enough water pressure. My previous Joven heater only requires 10kPa min pressure and it hardly gave me sudden cold water during shower.
However, just slightly over 2 years of usage, one of my Alpha 18e self detected an internal fault and rendered the heater totally useless. So I replaced it with a new Joven SA10E. This model has EELS safety feature such as built in 10mA automatic electrical leakage detector and surge protector. Of course, I make sure that this new Joven SA10E can also take minimum 10kPa of water pressure.

Great info, seems like Joven is more reliable

using Joven one.. so far so good

hope can last long

My shop has been selling joven for about 10 years, very little problem and that is why we only sell one brand til today

Joven good Malaysian brand made in Malaysia.

Bro,

The Joven SA10E has a built in 10mA automatic electrical leakage detector. What is the different between this 10mA detector and the external 10mA RCCB as per recommendation by Suruhanjaya Tenaga below:

Panasonic, Joven, centon, are good. Rinnai also good, but they seldom promote their heatee water here in Malaysia.

Without pump lifespan will be longer, with built-in pump, the lifespan will be shorter. I changed 3 water heater with built-in pump, while my mom room using direct water and no built-in pump is still running.

true. been using joven.. so far so good

will recommend people to buy

Panasonic or Joven

Where to purchase Joven at cheap price ? lazada or 11street since they got voucher discount .

panasonic. so many years not headache given. make sure you using filtered water

so joven or panasonic water heater better ?

can share the model?

not sure now what model, coz i did not change every year. haha

oh.. I referring to the model you are using now, is which model..

Been using Joven PC838P for like 7-8 years and the motor made loud noises recently. So i used it for another few months before purchasing the same model using Lazada. Bought it for RM389.30 and the supplier was from Liam Hup Hardware in Shah Alam.

I was amazed that the spoiled unit still can be used till date, good stuff!!

have to go back and check hoho

haha.. no problem bro.. still reading and survey now..

I have been using Panasonic.
Current house has 3 units and after 3 years no problem at all.
Old house used Panasonic for many years as well.
In fact just bought another 3 units for my new house renovation.
I find Panasonic after sales service to be good as well. My fan had a problem and thy came within 48 hours.
I used to have Carrier aircon and their after sales was BAs and took nearly a week. Happy that they closed shop.

how about joven i90p RS model?

Rubine? Is it good?

The poor Korean gal who got electrocuted at Seremban 2... I wonder which brand was she using? What are the safety measures to take? How to ensure the electrician is qualified?

Only 1 problem with Panasonic water heater. The hot water always not hot enough.

Any water heater will not hot enough if the flow of water is too fast.

Hei guy ,11street selling panasonic and joven heater quite cheap ,juz bought 5 fan ,now will go for water heater ,in shop they quote me RM320 for panasonic and 199 for china brand ,in 11street panasonic heater RM189 only

How much cost for installation nowaday ?

Hi,
Most of the retailers are being tied by the supplier's target and attractive trips in order for them to help to promote their brand. I believed you have walked in a not so big scale shop as both Midea and Deka are small players in Malaysia for water heater market.
Accordion to the market research company, both Joven and Alpha are leading water heater brand in Malaysia.
Do check out price from internet and the best time to buy water heater is during hot season (as suppliers struggle to sell their stocks to retailers and retailers struggle to sell their stocks to end user, hence selling price will drop drastically compare rainy days)

Hope my comment serve you well.

Be a smart consumer.

Price very expensive

Not sure , so far most of my friend intro Panasonic and Joven

Buy big brand maybe

Haha

Haha ,I believe so , now I only look at gemfive and lazada as the price offline really sucks

Hi.. @zheilwane.. How to purchase Joven water heater from your shop? I'm interested in either the pc880 range or pc820i or along the line.. Nee 3 units.

we are only selling SL30, I90, SA10e and 880p series only

I agreed. My Joven instant water heater 3.6kW performs better than panasonic 4.8kW.

Hi zheilwane, What is the main difference to the heater unit if you compare Joven SA8e and Joven SA10e? i notice the shower head is different, besides that any difference to heating unit or circuit board? which one is better?

AC and DC pump, make much difference?

Using Joven water heater..

good simple robust design..

Once magnet spoil so replace and good again..

Joven would be your best bet.

I've just moved to a new place with Panasonic heater installed so can only attest to it after I stay for an extended period.

For what type of water heater? Solar or normal instant water heater?

instant water heater

No difference. Some DC motor quiet but some noisier than AC

Been using panasonic for 7 years.. no problem

i'm currently using pensonic. bought from aeon big for 280++ with pump. So far no complaints.

I'm using Alpha. 7 and a half years with no issues.

Is Elba reliable?

Panasonic best!

hi may i knw what model panasonic u buy ?

2 years ago i dun wan buy Panasonic cos of its ugly design.. but now seems improved a bit ady.. now comparing Pana vs Rubine...

I need to find and buy a new water heater. I found information about the difference between an electric and a gas water heater https://www.newtanklesswaterheaters.com/wat...know-pros-cons/
I am in need of more information. My contractor recommended a electric tankless water heater but they don’t make it now I feel he is not the best source of information either. What can you recommend?

Tankless or instant is when you want ease of use and no hacking. It is not ideal for long duration high volume flow esp rain shower but can still work. Built-in pump is optional for condo (usually not necessary) but mandatory for top floor landed.

Tank storage hot water is when two or more bath outlets require centralised hot water. Assumes hot water plumbing already installed otherwise need to hack. Centralised is natural stepping stone to installing other centralised hot water systems like solar hot water or gas as the central hot water plumbing distribution is already there. Here the centralised tank will be relegated to backup heater on continuous rainy days. Pump is required for all top floor bathrooms or where pressure is weak.

Thank you for your advice!
Which pump would you recommend to choose?

I take it that you live in a landed then? The Panasonic models are good..They have been around for a long while. If your looking for a dedicated centralised water pump, refer to this thread. But I strongly don't recommend dedicated centralised pump unless used with centralised heater storage tank. Too many things can go wrong with two separate systems and a pressure reducer will have to be installed before the instant water heater.

rubine hear somebody say nt really good. that y looking panasonic
dh-3ndp1ms

how about Sharp WHP315. come with 5 year warranty for pump and heater?

https://www.lazada.com.my/sharp-instant-wat...r-19004129.html

it's pensonic. using it for my guest bathroom which is seldom used.

Model is 967ep i think.

for master room toilet, i am using panasonic. http://www.lazada.com.my/panasonic-r-serie...sc=MeoE&rb=1258

Pensonic is ac pump, abit noisy but better power. can control power. 1 year warranty on pump.

Panasonic not so noisy as it is dc pump. cant control pump speed but 5 years warranty on pump. need to change shower head. the one they gave is basic.

Can't control pump means cannot turn it only on when you need it? Means once heater turned on, pump also on?

This post has been edited by halcyon27: Nov 28 2017, 10:43 PM

yes

I see. Some models had optional pump control switch like Alpha / Joven rain shower model. Condos except for the top two floors don't need built in pump. Landed as well top two floor of condos will require. Anyway, here's an old gem of a thread complete with videos by zheilwane. This one too by ozak.

I posted the above review in July 2016 and now my 2nd Alpha Smart 18E die today. I guess smart water heater with smart chip doesn't last.

Cause of unit's demise attributed to what? This is condo or landed? If disconnecting the water pipe at the cold inlet, what kind of water comes out in the morning? Could it be that humidity is very high in the shower area? See if mitigating with a wall mounted or glass mounted extractor fan helps before deciding on the next replacement?

This post has been edited by halcyon27: Dec 28 2017, 08:38 AM

Not reliable electronic component.

That is why need a 2nd RCD near the heater. At least it is not a electronic component.

Life depend on the heater safety component is dangerous.

Anyone used this before? https://www.alphamalaysia.com/smart-revo-i

just get Panasonic, Joven or Alpha.
btw, Alpha brand quite ok because their technician will visit your house if your water heater got any issue. But of course is under warranty condition.

Are you telling the Alpha no good ?

You said it is good is because technician will visit if problem. I don't see the point of good on that heater unit.

Than only in warranty condition. Finish warranty, no coming ?

Anyone heard of hydro one?
https://www.hydro1.com.my/hydro-one-ecoheater/

Price ?

dun bother, macam like Seers. I stay away from any company got the word "Marketing" in their name

Ok boss.

Normally such rare heater in here will cost a bomb. They can claim how high tech and save cost, but the heater initial cost is high that can't return back the cost when calculate the usage.

Was quoted rm800 for 30 litres and rm900 for 50 litews

Bro care to share more?

Few hundred expensive. But price still afford I guess.

Go and try. Let us know here.

Makesure it safe enough. Don't pay too much attention on the high tech. But not safe to use.

According to the website its says zero risk of electrocution coz not using metal heating element.
Still dont know whether to choose Joven (RM 730 at 50L, using metal heating element and more electricity at 3kW+) or this.
Will share more if I try out the hydro one heater.

What type of piping do you intend to use for the connections?

If you use hdpe pipe( black with red lines) length more than 1 meter at both the input and output of the device.
There is zero risk of electrocution too.

If the shower you are using is non conductive and length of pipe more than 1 meter, risk also zero.

Just install any water heater correctly and you will not be electrocuted.

If you see the spec clearly, it didn't save much or pretty non. It selling point is the heating element.

Joven take 30min at 3kw to boil the water to 70°.

Hydro1 take 36min at 1.5kw to boil to 44°c. See the temp different.

I don't see the Hydro1 save in electricity.

And with temp 44 degrees, will end up using more of the hot water if use with mixer.

End up with needing bigger tank or higher wattage anyway.

30min at 3kW should be the JH35 model with 35L.

Hydro1 don’t have 30L model so let’s compare the 50L models from both brands.

Joven to 70C @
3kW takes 45mins
1.5kW takes 90 mins

Hydro1 to 44C @ 1.5kW takes 45mins, so it’ll take roughly 1 minute for 1C. To hit 70C I assume it’ll take an additional 26 minutes, so total time will be 71 minutes.

So with my assumption it performs ~26% better than Joven’s.

Please correct if I’m wrong.

Wrong.

It takes more energy and time if want to go higher. It is not a linear relationship.

Energy loss to surrounding due to temp difference will be more.

The lesser the temp difference between heating element and the water, the lower the heat transfer rate. Hence again, will take more time and energy.

So such calculation cannot be used. Any fluid thermodynamic engineer here that can shed more light ?

Fair enough. So now who can shed some light.

I’m just a layman. I’m looking at Hydro1 because of its claims of being safer.

Yes. Under warranty they will repair FOC but they charge RM70-80 trip cost! I have something broken within first year and still under warranty. They came and replace just something tiny (they told me it's not an expensive part), done within 10 minutes charged me RM70 or RM80 for the trip. Their reason is because their office is in Shah Alam. Like it's the consumer's fault that they are based deep inside Shah Alam?

After warranty period, it's trip cost + repair cost. Second time rosak, I just ask the person who helped me install the water pump to check (he got service water heater too).

I don't know if they're still doing the same policy, but I would not buy Alpha again. Of all the brands I used before ; Faber, Pensonic and Panasonic, this is the only one that I need to repair within first year of use.

So I am going to have one more water heater in my bathroom on ground floor. This bathroom has the best water pressure but unfortunately the developer did not install a water heater switch. Is it safe to add a switch? I think my old house at hometown add the switch for water heater, I just don't remember how they did it.

This post has been edited by lowlowc: May 24 2018, 06:55 PM

Get an electrician to do it properly.
Basically pull wire 4mm square from distribution board.
One end is a 20amp rcbo with 10mili amp leakage trip and the other end is a 20amp switch. Then from the switch 4mm square wire directly to the water heater terminal.

Any other way than that will have compromise on safety.

Thanks. Do you believe when I buy water heater + installation from shops like Sen Heng, Onking etc, the technicians should be trustworthy to handle this?

This post has been edited by lowlowc: May 24 2018, 10:15 PM

i don't know.

i basically trust no one. i either do it myself or i'll supervise closely whoever that's doing it personally.

your life and someone else's life depends on it.

if you want crappy installation, the crappiest installation i can think of will be take power from light switch in which light uses 1.5mm square wire or smaller, no earth wire, some how some idiot connect the light wire to a 32 amp mcb and the mcb connected to an old school elcb with 300mili amp leakage trip that no longer works even if press test button. and connect the water heater with a conductive shower hose. yup.........sure way to get electricuted and burn down the house in the process.

Hydro1 have 30L, 50L and 80L. Check at the Specification.

Base on the Eco30 L, 36min - 44°. If reach to 70° will take - 70/44x36= 57min.

Base on Eco50L, 45min - 44°. If reach to 70° will take - 70/44x45= 71min.

Base on the Joven JH35L, 60min - 70°.

Base on the Joven JH50L, 90min - 70°.

Too bad I don't have electrical knowledge to supervise the job.
That's what worries me - using the light switch to connect. I think the next nearest switch will be opposite the bathroom door, which is the switch I use for my washing machine.

Distribution board is meters away and have to go past 2 doors which means a lot of wall hacking.

This post has been edited by lowlowc: May 25 2018, 11:39 AM

So, I think Hydro1 is “better” since it’s a 1.5kW heating element?

Try la. no worry.

Later let us know here.

I don't see any good point of 1.5kw element. It is just lower power element. While Joven have 3kw and 1.5kw element.

In term of save, 50L have more advantage. Another is, it can adjust the temperature you want.

But for me, it is useless as the storage heater will be hide inside ceiling. If many people using, you have to set it max to reduce the hot water usage ratio.

The only point worry is, how long the heating element can last. And what is the cost to replace. This might turn you off.

Recently used a water heater in a hotel and it was very noisy during operation. I guess it must have come with a pump. Do pump-based water heaters sound noisy during operation?

I just installed 2 Panasonic water heaters (non-pump). Very quiet during operation. Though the water that comes out from the Panasonic is not very hot, just warm. Unlike the water heater in the hotel, when the temperature knob is only halfway, the water is already very hot and I have to turn it down a little. Personally I prefer the Panasonic water heater whereby the water is not too hot as you won't risk burning your skin during shower. Though for those who like to take a hot shower (hotter than warm), I'm not sure if the Panasonic water heater will deliver.

I was told by the electrician who installed the water heaters that most the water that comes out from modern water heater these days is just warm and not very hot.

The "crappy" installation that you cited, good imagination. Though in real life we rarely hear about buildings particularly apartments or condominiums being burnt down because of a wrongly-installed water heater. Most units in apartments would have water heaters installed, and I don't think I have read about any building being burnt down because of poor installation of water heaters. For burnt-down buildings, I believe a fire arson or flying jets crashing into buildings (just like the World Trade Centre) would stand a higher chance of getting the whole building on fire.

In summary, the message I am conveying here is it's not that difficult to find a competent electrician. Of course, one can choose not to trust the electrician since you wont' know his background (unless you scrutinize his credentials for certification) but in reality, most experienced or competent electricians would do fine. Otherwise, we would hear buildings being burnt down in the news every day of the week due to poorly installed water heaters.

Yes, good imagination.

But in real life, I’ve seen a lot of stuff that makes me wary of things.

I suggest you google the leading causes of residential fires in Malaysia.

I would guess either from cooking or an electrical fault and the victims are usually the very old or the very young.

These are the people we need to protect and it's a pity if ignorance is the excuse if we fail.

These things don't need to google. Electrical or gas cookers fault related to cooking is mainly with worn-out wires and fittings or misuse. It's not related to improper installation of new water heaters.

Going to get a instant water heater, any suggestion which is safer

Wouldn't it be better to have the storage water heater visible and easily accessible to adjust the thermostat, view the temp/pressure gauges and periodically test the pressure relieve valve?

In the same bathroom but high level..

Imagine have a tong gas size at the corner of the bathroom. That is the 40-50L size of a storage heater. With the piping and wiring, it is an eye sore in your bathroom. If with a small bathroom, it look crush in there.

Storage heater have to install height above. Who want to climb ladder adjust the knob everytime ? It is not same as instant heater height level. You going to knock your head with that tong gas size heater in the bathroom.

You can mix the water at the tap to get the right temperature you want. It is not same function as instant heater. There is no logic to adjust the temp...before use ?

It is not necessary to install a pressure gauge for the incoming water. I believe the tank can stand well above the normal house water pressure.

The pressure relieve valve don't have the gauge reading. It is just a spring load valve mechanism. You can test it once a yrs by pulling the shaft ring. So not necessary to be eye visible the storage heater. There is nothing to see at all.

The issue is more towards ease of maintenance rather than aesthetics. The thermostat is only to adjust an acceptable hot water temperature at the outlet once installed so as not to be scalding hot.

A high level located in a corner maybe near the WC and there's the drain pipe should the need to flush out the tank.The tank can no doubt withstand reasonable pressure still to visibly see a temperature/pressure indicator at normal is more peace of mind.

A water storage heater should not be treated like a water tank where an out of sight out of mind mentality prevails over safety/maintenance.

Still I would think a tankless water heater is preferable even if the water temperature/volume is less.

just went to SEC and Wah Lee yesterday to look for Joven water heater. Was told Joven is no longer reliable now so hardly find in most electrical shop. Is that true? The salesman ask me takes Panasonic or Alpha, but i resistant as i know Joven is the most reliable...
