Hidden Dangers Of Water Heaters: How To Install Safely? | Talking Point | Full Episode

[@anmolagrawal5358]

Talking Point is one of the best investigative series out there on YT. Keep it up guys! Appreciate all this crucial information that often gets overlooked by a lot of us

[@imranbecks]

That opening segment with the reenactment of the family that was killed by electrocution. I remember reading it in the news. So tragic. Imagine how traumatised the daughter was when she saw her father collapsing as well. Thankfully she was smart, probably noticed something wasn't right and did not reach in to her father, otherwise she would've been electrocuted as well. I cannot imagine the feelings she went through in the moment. The trauma she's going through now. Just sad.

@@Emsyaz So says who? The Quran is not the continuation of the Gospels or the rest of the New Testament. The Quran cannot substantiate itself according to the Bible ( the whole of Jewish writing in the Old and New Testament.) There is no reference of the seal of the prophets in the Old and New Testament. It is a writing (the Quran) meant to connect itself to the greatness of the Lord but the writing is not from God but from another source. The end of time will reveal this. It is a good thing the end of time is coming soon. The Lord Jesus will not come to smash the graves of Christians but he will come to take them away instead. It is called the Rapture or Catching away. This will be the greatest proof that God favors Christianity and not Islam. Millions or Billions of Christians will suddenly disappear. Hopefully in your lifetime and then you will know what is the truth. I pray you will have conviction and will put your faith in Jesus Christ on that day.

In my opinion, to protect innocent people, the sale of water heater should be regulated and sold only to licensed installer. The installation fee should be fixed by the appropriate authorities.

[@kitsura]

For all we know next time need to apply a permit to install water heaters. And the authorities will definitely charge a tidy admin fee for it.

[@tayboonl]

I learnt so much from this episode ! I was most impressed that the demonstration of the vast dangers by using electrical cabling that cannot support water heaters. Thanks to everyone whom produced this !

[@truth.speaker]

The sad thing is that the apartment was relatively new looking. Could it be that a licensed electrician was saving money by using substandard cable? We have no idea who installed it.

[@Time4Peace]

For electrical installation of water heater, there are at least conditions to consider: 1. Minimum standards for installation of both storage and non-storage heaters to be well communicated to water heater vendors and their contractors. 2. Qualified electricians to do the installation. Requiring a qualified electrician for every installation, while still highly recommended, may not be the most practical measure, given their availability and costs. As many of the shop contractors specialize in such installation and are almost doing it everyday, they are in a position to comply if the minimum standards are clearly communicated with penalties for non-compliance laid out. Surely something can and must be done to reduce the number of death by electrocution from water heaters.

[@duck_that_quacks]

If the Residual Current Device/GFCI (one of the BIG breakers) is working correctly, it can detect leakage of current from live to ground, and it will automatically trip in these cases, protecting the user.

[@noramaddy4409]

This report has no doubt saved many lives because now people have been informed just how important it is to have water heaters and electrical work done only by a professionally trained installer. Who is checking the official standards are met in the building of new apartment and office blocks?

[@kitsura]

This one will be checked especially for HDB projects. All the add-ons like water heater are the dangerous one.

[@chaozhouzi1984]

There are errors being presented as facts. Storage water heater has protection against overheating so pressure buildup is not due to this. 2 DP switches for the storage heater does not equate 2 energy source buildup to cause the fire. Pressure relief valve need to test for functionality and not just to ensure drain pipe is not plugged. LEW test for earth bonding, resistivity value of more than 1Ω and LEW claimed it is too high which is incorrect assumption without calculating the impedance. Steve your heater wiring of 1.5mm² may not be undersized ask your LEW to check against the conductor table in SS638. Please check against the correct table. Mr Wang stated water heater draws a current of 14 to 20A. He needs to clarify that he is referring to storage heater and not single point instant heater, subsequent images show man showering using instant heater. The cable used to demo it heating up, he neglect to state cable is undersized.

[@mrtechie6810]

Good comment. Our storage heater is only 10 amperes (at 240V).

[@joantan8543]

Hi, do you think you can advise in terms of safety (leakage/explosion) which is relatively safer, storage tank or instant heater?

[@chaozhouzi1984]

Subsequent to my comment, for earth bonding, as a rule of thumb value of less than 1 ohm is acceptable. Learnt this from a colleague recently, he told me this save the hassle of having to calculate the impedance.

[@kirie-8524]

Excellent documentary as usual, always interesting and relevant topics to learn more about.

[@muhammadkhalilbinabdullate6183]

Brilliant, informative and direct. Thank you for doing this episode. 👏

[@xJayteee]

My question is this. I've always wondered what's the point of a Fuse in the 3 pin plug? Fuses generally are meant to prevent this kind of things no ? Once current draw exceeds 13amps , it's supposed to break internally , severing the connection and preventing a short . In this scenario , the wires already fused and connected to each other and STILL the fuse did not do anything when it is supposed to when the current draw exceeded 13amps.

[@lucretius8050]

I believe those 3 pin installs purposefully bypass the fuses, water heaters will to draw more than 13A so the standard usage would have already cause trips. Additionally it is likely RCCB was also bypassed for the first case as electrocution by leakage didn't trip the breaker causing subsequent electrocution.

[@xJayteee]

@@lucretius8050 RCCB yes , Higher chance of getting bypassed by 'electricians' , 3 pin plugs however no. In the test that is shown in the video where he launches a extreme load test , You can see the fuse is still in the plug and yet the plug overheated to the point where even the wires melted which means the fuse did NOTHING to stop it. I've had multiple melted plugs before and this question has always confused me as to WHY is the fuse not preventing anything. Only when melt until short circuit then the breaker trips ? A fire would've started before it trips.

[@lucretius8050]

​@@xJayteee​From my knowledge the fuse should have tripped (or maybe i just have poor knowledge), melted cables can also be caused by frayed core wire, poor quality, using thin cables to over extend, cable wear, poor connection which does not actually increase the actual load. It is melting cause it can't hold 13A load so it is "breaking" before the fuse.

[@kelvinlee7226]

In some cases, there are electricians that would just wound copper wires where the fuse should be. This bypasses the safety features of the fuse. In some cases, the wires were under-gauged, being unable to even carry 13 amps in the first place. So wires giving up (burning) before the fuse gave way. (you can see this in the check the electrician in the video did with the ohm-meter, and got the resistance reading) I've done solar work as a hobby, I have an EE background, but for serious work, I'd still bring in a license electrician any day, pays to be safe. In some cases, an unlicensed electricians could also invalidate your insurance policy, so makes sense to get a proper electrician and plumber to sort your devices out. Stay safe folks.

[@xJayteee]

@@kelvinlee7226 Probably then . Idk. I've tried some experiments , trying to overload the plug so I can try to get the fuse to pop but was to no avail .I ran a 18amp load through , and the plastic around the pins melted before the fuse did anything so I still don't understand what the purpose of it is. If you're willing to share , years back I wanted to try solar power as well. But I couldn't figure out how to connect it to the grid power so I could switch inbetween grid and solar. So I had to run a inverter from my powerbank , to my inverter and connect it to a 3 pin plug to my select few appliances. Can you share how you ran it along with the grid?

[@andyhooutdoors]

I just feel that a law should be passed making it mandatory for contractors to engage only licensed electricians and plumbers. But then I wonder if this might be possible at all considering that only a small percentage are licensed?

[@jchock7503]

Usually the small wall installed water heater also has its own safety electrical circuit called a ELCB ( Electric Leakage Circuit Breaker) that comes with a small test button on the water heater itself. The person using the water heater from time to time must check that this circuit breaker is working by first switching on the power and then pressing that small button to trip (stop) the electricity supply to the heater. This is an additional safety circuit on top of the RCCB ( Residual Current Circuit Breaker) found in the main electrical board/box of the house or apartment which must also be tested on a regular basis to make sure it is working.

[@o0o74]

misleading information 1. installation manual of every electric tankless water heater don't recommend metal fittings, it even come with non metal parts, so if you go for metal, the fitting has to be grounded 2. electrocution in most cases is caused by faults with the unit itself without rcd / rccd rated for life injury protection installed 3. explosions in most cases is also caused by faults with the unit itself and faulty pressure relief valve 4. most new tank water heater don't recommend drainage, if water is coming out of the unit and wreak , it's a tell tale sign that parts replacement is needed the worst offend of all is not talking about today's standard water heater must be in it's own circuit, no plug in, with proper rated amperage and type of circuit breaker, rcd / rccd rated for life injury protection, or rcbo. RCD / RCCD / RCBO have to be tested at regular interval.

[@raymondlow393]

So besides telling the public to only engage licensed electricians and water heater installation technicians to carry out the job for their homes, what other steps have the government taken to prevent more of such accidents fatal or otherwise from happening ? What kind of penalties is in place if an unlicensed electrician is caught doing electrical installation works for home owners cos if I can remember, there hasn't been any unlicensed electricians being hauled to court for carrying out electrical works. Had I not watched this video, I won't even know of all these potential danger of having a water heater at home, and I am very sure 9 out of ten families are not aware of this too.

[@owenchuarbx]

As a electrician in training. This is pretty educational. Thanks again

[@eisenklad]

using lower gauge/thinner cables is how some electrician save money. i've seen it done to a heated food display unit. the wire from the mains went into a splitter to make sure the wires dont contact each other. but the wires from the splitter to the thermostat and wires joined to the heating elements cables are of 2 sizes too small. as a result, they lasted a week before melting their insulation. having two switches to a single water heater doesnt mean the heater gets double the power. it can draw more current if there's a fault in the heater/wiring. the wife was faster thinking in that case to switch the circuit breaker off. in a fire, switch off the power and gas. you smell gas, shut off any flame and mains power. there's a reason why there's a breaker under your electricity meter outside of apartment. here's another thing to take note of, older HDBs have thinner cables, the circuits design is 15Amps while current new homes is 20Amps and 25-30 amps for high power devices(AC units/ovens/fridges). if you are moving into a 30-40yr old HDB. check the home wiring, either from prev owners or getting an electrician. my current home is 40yrs old, turning on circular Fluorescent lights causes brownout due to how old the circuits are and it has caused my desktop PC to crash.

[@lzh4950]

My old house meanwhile is probably 1 of the minority with a 15A power point in the laundry yard (so the pins are circular instead of rectangular) for older washing machines, but newer ones draw 13A instead & thus use the more common rectangular 3-pin plug (BS1363). So when my family changed to a newer washing machine, we had to change to a 15A plug too

Should the pressure release valve be made to be a compulsory item in the storage water heater? Should the authority makes it mandatory in installation? Most consumers don't know what are involved in installation. The shoo doing the installation could be made accountable.

Permanent high current installations should be directly wired. If the plug is loose in the socket, or corroded, it will heat up, even at lower currents. The fuse offers no protection against this. Nor does it protect against loose wires nor any bad contact -- that will overheat and cause fire. All connections should be inspected, and the loop tested for low resistance or checked under load with an infrared camera to verify there is nothing overheating.

[@xonx209]

Checking with an infrared camera is a good idea, not just for water heater, but all electrical wires and outlets. You don't need to be an electrician to do this since using infrared camera is not dangerous.

Always check the water that comes out from the tank, whether it is clear or contains rust particles. If rust is detected, is a tell tale sign of tank leak. When replacing a water heater, ensure the 15amp electrical 2.5mm cable is safe (flexible) and not stiff. Safety pressure valve(copper) must be new n check rust regularly.

The incident at the beginning - after investigation, wasn't it reported that the upgrading works of those HDB blocks did not include the wiring in the toilets henced that part of the circuit wasn't protected by any circuit breakers? Conveniently left out of this talking point?

To be safe, simply connect an extra wire to earth.

Hi Steven, I recently received a letter from HDB informing about plans to upgrade flats with older electrical systems to those with RCCBs. This was due to the case where a family of 3 were electrocuted from an incorrectly wired water heater. I went back to read the judges verdict and was surprised that the flat had already been upgraded with an RCCB during the HUP to add a utility room in the kitchen. Unfortunately, the RCCB only served the utility room. Although not clear, the report seemed imply that the electrician had only routed wires from the RCCB protected circuit to the utility room, essentially creating a distribution box with a dual electrical system. This was in 2003 after RCCBs were mandated in all new HDB flats. I am not sure if the EMA has electrical codes requiring newly installed RCCB must cover the entire electrical system rather than just a single circuit, so cannot comment if any rule was broken by the electrician. I wrote to EMA to enquire about the possibiliy of my home electrical system being upgraded as my home is fitted with an ELCB which predates the RCCB, and wanted to know if we would be included in this upgrading programme. Sadly, I was informed that we were not included as the RCCB is merely a renamed ELCB. EMA is not completely wrong of course because the original ELCB, which is a voltage sensing device that detects voltage leakage through the ground wire, whereas the RCCB, which was first called the current-operated ELCB was renamed to prevent confusion amongst electricians. However they differ drastically in operation and should not be confused with each other. Whilst RCCBs can detect any leakage in current (either through a short circuit in groung wiring or an alternative ground return such as through an object or person during an electrocution) the ELCB is severly limited to just leakage through the ground wire (which modern appliances tend to lack). Perhaps Talking Point could explore this topic further in your next episode? It is likely that a larger percentage of homes are currently installed with less protective ELCBs than RCCBs.

Water heater circuit must be required to protected by an RCBO.

When the plumber said unlicensed people may not understand the pressure release valve, I felt his "oh no"

[@boonkailee8237]

Why no RCD device installed to cut off power supply when such thing happened

[@djangocc3315]

Very interesting, gives me thoughts now as am close to building my bunglow house in the Philippines

[@rzkysyz]

Ha! A licensed electrician and plumber. Sounds like a pipe dream here in Indonesia. But nice info. Wished I knew this when I was building my house.

[@adbrozonez6068]

Most important is you are trained practically and theory important is practical. To get licensed nowadays not easy to have even if u know well. PE electrical some basic practical they also not sure ..they are more on paper work drawing and inspection. Practical mostly is people who have no licensed like your electrical or plumbing HDB PROJECTS ALL DONE BY LOCALS HANDYMAN AND FOREIGNERS WITH NO LICENSE BUT COMPETENT. sorry to said this but the truth is like that.. cow's milk the owner got the name 😁 sorry if I offended any one , iam a practical guy have ATTENDED COURSES WITH MORE THEN 15 YEARS OF EXPERIENCE. AND A LICENSED TECH HAVE 2 YEARS EXPERIENCE... THE POINT IS WE NEED EACHOTHER HELP... 👍

[@lucash1980]

The answer is not to legislate and idiot-proof everything. The answer is to educate. Capping or blocking a pressure relief valve to stop a leak is a stupid and cheap move. Putting 15amp wire on a 20amp circuit is a stupid and cheap move. Running a heater with a damaged wire is a stupid and cheap move. Not installing or maintaining safety protection on circuits in wet areas is a stupid and cheap move. Arc fault protection and Ground Fault Interrupt protection is $30-60 to protect a circuit and older systems can still have the protection added. Fix the broken things, or don't use them. All of these things are easily prevented. I'm sorry to hear about people being injured or killed from such negligence. If you have the money to buy this equipment, then install it correctly and maintain it. Stop trying to penny-pinch--pay a proper contractor for a proper job. Don't take the lowest bidder. Read a book, watch some learning videos. This isn't rocket science: bigger amps=bigger wires, water does not compress and heating water expands, water is conductive and electricity can kill you if conducted through you (electricity is also invisible).

[@lbcck2527]

I just watched this video and there is mentioned that water heater current is between 14 to 20 amps. Here is where I am confused, why 1. does the 13amp fuse in the plug not blow out ? 2. the ELCB (earth leakage circuit breaker) does not trip ? Here, the 2 "fail safe" mechanisms typically installed in our flats have themselves failed and killed the occupants.

[@darren424242]

The time a fuse takes to blow depends on how much of an overload there is, the higher the overload the faster it blows. A small overload will still blow the fuse eventually. An ELCB/RCCB will only trip when there is an earth leakage fault, it will not trip for an overload fault. A CB is the device that protects against overload faults so that is why you typically use both in an electrical installation. A RCBO combines both earth leakage and overload protection into a single device.

Im afraid to shower after watching this ep....

[@imranbecks]

Showering is fine. It's the water heater connection that killed them. If you're afraid, just shower without turning on the water heater.

[@junkthe]

This Video is wrong ! And this video is not solving the real problem. Any men without licence or with licence will not solved the problem. This video is not real Expert. This video is misleading. All i said is because already hapened here im my country about 3years ago. All that store have demo of it, and its all burned. And last year they tried to renovate the building. Wont change the memory of that.

The same things happened in Malaysia. A Japanese couple was electrocuted due to ELCB malfunction. RCCB with 10mA leakage breaker is a must.

Very informative episode more needs to be done such as trusted water heater installation contact numbers for contractors

[@okzzvil7617]

One of the best solution: Since Singapore is in tropical area. No maintainance, No cost , Safety = Do not use water heater. Boom. That's it.

@3:20: No, my friend. No. You're not grounded and the path through your finger is definitely non-lethal... probably hardly even tingly.

[@tbas8741]

Firstly Why are they installed in bathroom. Instant water heaters are meant to be installed in the bathroom in first place. 2nd they should never be connected to a normal power point with thin wires, but wired into the electical wiriig properly. 2rd they should be mounted in basement or a dry room

[@ncooty]

Many things must be wired incorrectly for this to happen. It's very important to ensure electricians are licensed and to enforce building codes.

[@Jianfa88Tsai]

Rubber is cheap. Use Navy Seals rubber boat military grade durable and elastic rubber to insulate the entire case and piping of the instant water heater to reduce electrocution risks?

[@CollosalTrollge]

I dont understand this earth wire and how it works, because in the Philippines it seems they never use it, how does this protect us? Sound equipment u can hear buzzing noise so i am guessing this is because of no earth.

[@Techie1224]

if your device have controlled by switches at diffrent location that doesn't multiply the current the device draw,,

[@uluhitah12]

the best option is not using water heater at all. cold water is more healthy

[@MrDrone-qt6sw]

How two switches will increase current consumption dude the geaser will consume only what it requires it doesn’t matter how may switches you connect

Electric water heater should have safety breaker for leakage current. It will cut off the electticity if there is a leakage current.

[@tenweipeng2199]

Solar heater is the way to go. The Indian guy said his water heater draw 32A each which is impossible.. no way a water heater use 7000W of power...
