That's good. At the end of the selection, do remember to take note of the amp required because you need to buy the switch/socket for it

For eg, the rinnai induction hob is 8kWh or 8000W. So 8000W / by 230 or 240V = 33 or 34A for the power switch rating. Which means you need to get at least 45A DP switch socket for the stove alone. I think 6mm dedicated wiring is probably good enough for the stove switch as your power rating is higher than mine although induction is energy saving.
This is because normal wiring used for other sockets in the house cannot withstand the heat from the power load for the stove and can blow or in worse case, catch fire? So do ensure that you have a set of wire mainly for stove, a set for hood, and a set for built in oven if any. No sharing with other appliances either.

Im not sure about the hood as I never use a hood before.

It's better you look at the amp rating for the model you choose, then enquire with the electrician on whether 6mm wiring is sufficient or not. When you buy the switches from the hardware shop selling switches, check with the man on the switch that can handle the amp rating.

Was looking at your choices.

I would feel that if I have a child or elderly parents staying with me, I will focus on safety and security functions first, the quality of stove and lastly budget too. The brand will come later. I am firm in getting european made appliances because the performance is stable based on experience, although I am not opposed to getting asian made appliances either.

Based on my requirements, I think Electrolux models, EHET66CS & EHED63CS have the safety and security functions and the fact electrolux is european made? Rinnai comes 2nd. For Teka stove u shortlist, there is no mention of the safety lock etc.

Price plays a big factor in this as well primarily because of the main reasoning that appliances have std 1 year warranty and it will not be well justified to spend so much with this in mind that the lifespan really varies with maintenance and usage. Additionally, so many new models come on the market just like how TVs are priced high and later discounted heavily when new models appear.

I don't know how much are you willing to spend on the stove though.

EDIT: I just saw your teka shortlist choice has a safety block which can be said to be child safety feature and useful for cleaning purposes as well. So Teka can be placed at 2nd place already. The power rating is at 6400W, not that high as Rinnai's if you consider electricity usage.

Teka has a 45cm 2 zone hob but price wise, I saw it is RM2975.

---> It's good that you gave me a detailed explanation on this. I was completely clueless on this bit. I thought I will start narrowing down my choices in terms of the dimension, brand, price and features first and then get back here with the technical details advice. I don't have any contact of electrician that I can seek advice from. Was going to ask my KC maker (or his electrician) what is needed in terms of wiring etc. before I finalize my decision.

Which model out of the three I shortlisted would you recommend me to choose? And why? Also, apart from what I have shortlisted - I would still welcome suggestions of any other brands (which is reasonably priced and good quality) that I can look out for. Thanks.

Saw this 2 zone hob at xammax

http://www.xammax.my/teka-induction-hob-ir-421.html

If you want to get from xammax,you can get RM50 voucher to discount the price.

http://www.xammax.my/blog/get-rm50-coupon-...share-our-page/

and also the free gifts for purchase of RM1200 and above here.

http://www.xammax.my/blog/select-free-gifts/

Yes 3-4 zone hobs will have higher wattage. If you look at the specs closely, sometimes 2 bigger zone will have higher wattage than the other 2 smaller zones in a 4 zone induction hob. But the total wattage is calculated if you add all the wattage of the 4 zones. It just depends on your cooking preference. Do you need a 2 , 3 or 4 zone hob?

For e.g., the Teka 2 zone hob I just posted above, is 4800W while your teka shortlisted choice is 6400W.

One of the Electrolux models is 7400W and the other one is 6400W

For electrical wiring, you need to check how much is the 4-6mm wiring? Based on my electrical quote, a 4mm wire is RM150. Take this as a base estimate (Price will differ by area so I don't know how is it in KL side) and you can ask for some discount or negotiate for a lower price if you engaging electrician to do all your wiring?

I calculated the wattage for the Teka IR421 at 4800W but when I checked the technical specs.

It says here that 1 Ring Ø250mm 3.0kW, 1 Ring Ø145mm 1.8kW which is a total of 4.8kW or 4800W but the description further says that the nominal connection rating is 3.2kW or 15Amp.

So to be on the safe side, you can get a switch with rating of 20Amp and thicker wires at 6mm because 4800 / 230-240V = 20Amp

Bro, I'm confused now?

I calculated the total wattage of all 4 zones of my vitroceramic hob and it matches the nominal rating stated for the hob.

How is it that yours is different?

I checked the total wattage of the IR421 and it is at 3.2kW / 4.8kW based on the wattage in description although nominal rating is at 3.2kW

QUOTE(idoblu @ Nov 10 2014, 06:30 PM)
I already posted about the smaller size IR421 3 pages back... biggrin.gif
As for the power...they rate it at all burners doing full power. In real life practice, you won't be using all zones at maximum power. You can't anyway, the hob won't let you.

My IR631 has three burners. At max, each individual burner can do 1800/3000/3200 but the maximum norminal power is 6400 watt, therefore the ampere require will be 27 amp only. A 32amp breaker would be more than sufficient.

IR641 also has a max nominal rating of 6400 watts. If you want to add all the highest wattage for each burner, it will be 9400 watts....lol. Simply put, you don't add all the zone's wattage to get the total power

Please ask Teka or whatever brand you are buying

Hmm? My old vitroceramic hob is ariston but I cannot use both zone at same time to cook due to amp. This is in a apartment flat.

Not sure about the new hob now but as far as I am concerned, my electricity bill have not hit Rm50 for the past 2 months since I moved in.

Relax! Just choose what you are comfortable with?

The 45cm Teka IR421 is not big or small either, you have extra 15cm of countertop space.

QUOTE(Career26 @ Nov 10 2014, 09:34 PM)
I am going to make a confession - with all this wattage, amps, power, technicalities - I AM COMPLETELY LOST!  rclxub.gif  sweat.gif  rclxub.gif  My search process is based on the following factors:

1. 60 cm
2. 2 zones
3. Low wattage
4. Reasonably priced and reliable brand

Am I still on the right track or am I missing out something ?

If you see it differently,

The overall wattage of the stove will also impact electrical bill based on usage. Is it daily or once in a while?

As Career26 mentioned she is intending to do light cooking which equates to not that frequent cooking in my opinion of what is frequent and what is not so frequent. which is why I think a 2 zone hob is good for her usage pattern.

But if it's frequent, then a 3 zone hob is enough.

Try measuring 45cm vs 60cm with a measuring tape on a table. You can have a better idea of whether it is small or not.

The promotion price for RM3188 is for both? I doubt you can get 2-2.5k for induction hob as induction hobs are more expensive than vitroceramic hobs unless there is a sale on. Speaking of which, christmas is coming up and there could be a christmas sale?

I'm a night owl so no worries.

2-3 times a week would be infrequent because there are 7 days in a week. So it would be 4-5 days without cooking

If 3-4 times a week, it would be in between infrequent and frequent considering, it would be 3-4 days without cooking.

If you cook 4-5 times a week, that would be frequent because it would be a long time affair with the stove and fridge due to food stock up and the no of zones to prepare a fast meal.

Regarding the teka stove n hood from xammax. If you got RM50 voucher from xammax to offset the total price, you can think of it as this.. RM2625-RM50 = RM2575 which would then be less of a stretch on your maximum budget for stove by RM75 only because the hood is cheap.

It would depend on how well you maintain & use the hob.

My old vitroceramic ariston hob is already close to 7 years and still working! It has seen frequent cooking as well and only 1 time, the fuse blew but that was fixed and no other problem came up that required me to call ariston's service centre either.

QUOTE(weikee @ Nov 11 2014, 09:54 AM)
You need to take into consideration Induction hob lifespan are short, therefore get a reputable brand product easier to claim warranty. Never the less the radiant type hob is not that reliable too (especially with the fancy controller). 

Is simple, electronic stuff just don't go well with heat.

Ya depend on luck & usage pattern?

I choose not to seal the hob sides to my countertop because if have problem, can take out. It's fuss free. Need to make sure the hole is a proper fit

QUOTE(weikee @ Nov 11 2014, 02:40 PM)
Friend just replace his 3 years Vitro hob from JF Home, and my colleague Teka induction claim warranty 3 times, funny the same model Teka, his sister using much longer without issue.  Could be luck, or the usage pattern. Both seldom cook.

For me, I never had to seek advice from my electrician for my hob wiring before purchasing the hob

Usually electricians should advise you on the wiring type after you have purchased the hob so that he knows the power rating for it.

But as halcyon27 asked about your condo period, then it is better to check with the condo management on the wiring as they should know best whether the wiring is meant to accommodate high or low wattage for electrical hobs or appliances.

Unlike landed property where owners can plan and even add new electrical setups, it is different for condos due to building restrictions and limitations regarding renovation because firstly the whole block is on same water supply, piping lines etc and probably similar electrical lines. Also maintenance for water supply and electrical supply is usually handled by the JMB for the condo if I am not mistaken. It might differ or vary among the management for each condo though.

Looks like you have 63A for your DB (can the others confirm this too?)

Based on your electrical layout, you do have electrical points for aircons, heater (20A gang switch, but no 15A switch socket faceplate because the aircons and heaters have their plugs for 15A switch sockets while the 20A gang switch is like a relay to turn on the aircon or heater)

QUOTE(Career26 @ Nov 12 2014, 10:48 PM)
Friends,

I managed to get a snapshot of Electrical installation layouts from my home owner's manual. For all those poured their inputs based on various assumption, I hope the shots are clear enough for you to study the layout and advise me accordingly. Thanks guys smile.gif

Isn't a 10mm better?

QUOTE(ozak @ Nov 13 2014, 06:33 PM)
From the plan, you still have to tarik a 4mm wire to the kitchen if you want to install a cooker and hob. And a 32A MB. The easy way less hacking is go through the top if you plan to plaster ceiling. Just hack the DB box wall and the cooker place wall to conceal the wire.

Your B/5 2socket probably need for fridge and others. While the B/4 2socket is probably for WM (yard) and you can't share with cooker anymore. Both wire are 2.5mm size.

She haven't decided yet. Still considering between a 2 zone and a 3 zone or 4 zone induction hob at the moment.

But I assume that, cooking hob, hood will need dedicated wiring and if not a built in oven, there is a possibility of a table top microwave or microwave with convectional function in future???

That i know on the no sharing part.

Only thing is.. A 2 zone hob is 4800W while a 3 and 4 zone can be anywhere between 6000-800W for nominal rating.

That's why I ask if 10mm is best although 6mm might be good enough?

QUOTE(ozak @ Nov 13 2014, 08:50 PM)
You only can have hood and hob on the dedicate wiring. Can't have other appliance and share.

Still got 3 wall socket. Use that 3 for other applicance.

4mm size can use max 4800w.

Bro, you should read back the last few pages.

Career26's shortlisted choices have nominal power connection of 6400-8000W although not confirm on her final choice

Most induction and vitroceramic hobs have high W depending on the no of zones.

Assuming we do not utilize all, maybe 3 out of 4 zones for example... Still will be up to 4000-5000W as an estimate so 4mm can carry all max? Lol that's why asking whether 6mm is enough or 10mm still better?

Gas would be cheaper but there's space constraints in the kitchen and her hob size must be 60cm. Hardly see 60cm gas hobs which is limited. That's why induction hob next alternative.

QUOTE(ozak @ Nov 13 2014, 11:18 PM)
Wow, do you really need that high watt? That freaking high consumption. Using gas cheaper?

6mm is enough.

I think it is not a problem for her as she is single and doing light cooking?

QUOTE(ozak @ Nov 14 2014, 01:00 AM)
If want play safe, 6mm if enough. You can go higher, but wire cost is not cheap. Do some costing and see what best. Decide the wattage cooker than sizing the wire.

I have a 58cm 4 burner gas cooker. A display unit in the kitchen.  tongue.gif  while using 1800w induction cooker. From experience, I won't go over 3600w for a induction cooker. My meal will be expensive. sweat.gif 

Let say a 4500w run for 1/2hr cook each day and only use 1/2mth cooking, the consumption can suck 34kwh/mth. That 34kwh x 0.334= Rm11.3/mth. If full mth cook......

So a gas cooker will be lower cost? How much a gas tank? Installation cheaper? Just some suggestion TS.

If u decide on a teka model, can ask them to reserve for you 1st and get the dimensions for it.

30cm is also fine but you won't be able to use both zones at the same time to cook because the zones are spaced closely and not ideal for for using big and small utensils together. The old hob Im using before is a 30cm.

Hm the current wiring is new if your place is a recent project, but it would be good if your electrician checks that the wiring is properly done for peace of mind because some developers can cut material quality to save cost. Ensure your electrician is a good one, not the type to BS and chop carrot fast)

Since you need to put in new wiring dedicated to cooking hob, you need to check which side is the hob's wire on? Left or right side because the hob's wire which is the wire for plug but without a plug..needs to be run underneath and out of the cabinets side if necessary to connect to the wall socket outside.

The location of the socket is as important since your KC maker will need to work around it for the hob.

What else am I missing out? hmm.gif

QUOTE(Career26 @ Nov 14 2014, 05:02 PM)
Friends,

1. I am revising my shortlisted options for Induction hobs (might be opting for 30 cm modular hobs - Teka brand mostly are out of stock and will not be available till end of January). - 2 zones, low wattage, more space on the counter top, aesthetically nice and able to get one at below 2K. I will present my list here once I am done.

2. I am getting an Electrician to do a sanity check as advised by halycon27. I will also post a photo of the actual DB box here in the forum as suggested by him for further discussion if needed.

3. I am not considering gas due to space constraints and the hassle of changing gas cylinder, and allocating a whole available space for the cylinder. S'aimer has summarised enough of why I discounted the idea of having gas.

4. I need a help. Can someone help to come up with a checklist of questions that I should ask the electrician?
Do I need to check with the developer anything on the existing electrical wiring?

Appreciate all your inputs presented so far. smile.gif
