Would you care to elaborate? What was your personal experience in dealing with "these people"? If there is any problem I'm sure the owner would be pleased to hear any constructive criticism you may have, and I'm sure he’ll do his best to rectify any issues that you are dissatisfied with.

just to reverse lees theory, you can buy a honda jazz, put nice wheels on it, leather seats, all the wistles bells and toys , a mercedes badge, but its still a honda jazz. same with a house. just because it has a 10 million price , dont make it worth 10 million , in my opinion, in that location with the kuxury fittings these houses undoubtedly have, ignoring the fact that the basic structure is done on the cheap , these houses are worth no more than 12000, baht per square metre, so unless each house is 833 square metres which is roughly 8333 square feet, they are well and truly over priced. i would estimate they are no more than 300 to 400 square metres tops, so they would be worth 4.8 million at the very most . so unless that little piece of land they stand on is valued at over 5 million per plot, i estimate that each plot is less than 200 square wah which would make the land price 10 million per rai , im affraid anyone buying is being well and truly taken to the cleaners . expensive business being flash !!!!!!!!

Thank you for your opinion saint. I guess you won't be buying one then.

i not that keen on the honda jazz , but ive had a couple of mercs , not south african ones though . never had a problem with either.

Beer Monkey,
I have neither "brought" one or bought one.

by **saint** » July 15, 2008, 12:55 pm

but did you buy one ?

by **aznyron** » July 15, 2008, 1:10 pm

hows 5000 baht a sq/meter plus land ?

AussieBoy wrote:What kills is those Tankless Water Heaters TWH, Oh YOu fools who install them, and not connect the mains to a RCD, Yes you say, the unit has a built in RCD/ ELCB, your correct, but in all the units I inspected some 20 plus at Global House the RCD only protected the unit, So what happens in a TWH

The RCD protects if there is a fault in the unit or water leaks/ steam / moisture to cross the Active / Nutural wire to form a circut, which goes down the path of the water to Big FAT FARANG, forget about Viragra or watermelon, you will have a instant stiff woody! and dead on the floor, so in comes the misses to see what the comotion is all about and Bang! 1 fried Pussy, and so the live wire is waiting for the kids to come to see whats happing, True story of 3 dead in Cairns from faulty water heater.

So the TWH has just triped out, if you have no RCD on the house mains , do nothing but get out of there fast, turn off the power at the mains

HERES the problem, them there TWH has 2 wires supplying power, feed wire, no problem,
The feed wire to the unit go inside the unit, no problem so far,
The Feed wire connect to the Unit wires inside the unit and the RCD/ ELCB, no problem
The TWH after a few years will fail, the tank splits, plastic or the copper tank corrodes, or the pipe will fail at the joints, inside the unit no problem as when this happens the water will cause the short between wires and the trusty RCD/ elcb will kick off the power FEEDING THE HOT WATER TANK. fat farang is safe. !WRONG!

The tank is now isolated from the supply, the 2 wires comming into the unit, BUT those 2 wires comming into the unit if they are not on a RCD protected circut, THEY ARE STILL ALIVE, this is the false impression that the TWH are safe

So now your tank has failed, the small tank blew a hole in it from old age or corrosion, water spurts out hits the ground wire and the Unit RCD/ ELCB shuts off the supply, the water now hits the 2 wires suppling the power comming into the Unit, as you have not protected that circut with and RCD at the main box the water will pick up the current from the units supply and take it to the Fat farang having a shower.

SO whats the problem and how to solve it.

The power supply comming into the unit will be joined up with the units wire to give the unit power, the problem is that the junction of these wires where they are joined IS NOT IN A WATER PROOF JUNCTION BOX, some of the expensive TWH have proper water proof junction connection box, but most just a simple plastic joiner, So when the water leakes onto the junction box it can access the live wires, the unit will trip but the mains power feeding the unit will still be !HOT!

Put a RCD and the main power supply to your home, water proof the junction of the Units wires, to many think the unit is safe, but if you have no RCD on the house it useless.

Any one with a TWH can take off the cover, take a photo of it and post it here, I will mark on the photo the above problem

Have a Powerfull day

OK now what is the solution ? I have a hot water Heater and my building is grounded. so what should I do to be safe ?

Before we get carried away here lets remember that electricity reacts in very predictable ways (although sometimes it doesn't seem like it) and will always follow the path of least resistance. If there were to be a catastrophic failure as was suggested and the unit is properly grounded, most of the current will take this path, however some of the current could travel through yourself if conditions were just right. My thinking is that far more people are injured/killed from slipping and falling in shower than by electrical causes.

Hi. jetdoc.Agree with you 100%, and i'll have to remember not to take a shower on a day that ends in a y. There are theories that state having a earth can be lethal. in the British Isles there in a law to have a earth to quote the 17 edition The earth has to go back to the supply station as well. In a case in the 1980's a house had a earth fault an a person living 2 miles away was killed when he touched his electric fire. The earth fault had made his house leathal if he touched anything that was earthed.But everyone has there own views and i respect that,
Cheers Doug

Install a RCD on you mains powerbox

take the cover off your HW unit and I will be able to show you where the problem lays, take a photo of it

looking for one here in OZ but not popular here

by **AussieBoy** » July 16, 2008, 3:29 pm

Now you can see the problem, the red black wires comming from the junction box, the plastic junction on the right, you can see the 3 terminals and the screws holding the wires in place, just under that you and see the green earth and 2 strait lines representing the supply from your power box.

To the left of the junction box is the ELCB/ RCD for the HW unit, so when the tank the blue coloue bits breaks / fails or the pipes comming into the tank leaks the water/ blue bits can squirt all over the internal unit, note that the junction box is totally open to water penatration, Not sealed so all though the unit has cut off power to the top of the tank big red / black wires the power feeding these wires is still Alive, so the power will take the path of least resistance, maybe it will travel down along the green ground wire / maybe it will travel the path of the water to you.

So if the supply power is protected by RCD, then when the water leaks out the unit trips and the mains supply to the unit will trip at you supply box inside the house as well
No power at all to your unit

Just another powered day saving your life ,50 baht thanks

Aussie in my country we have a GFCI meaning ground fault circuit interrupter and also they put them on the wall outside the toilet so if what you say happens it trips the GFCI and all electric power is shut off also I have circuit breakers which is suppose to trip when there is a electrical problem
even high moisture could trip the power

by **Pakawala** » July 17, 2008, 10:02 am

Aussie Boy, how about just taking a tube or 2 of RTV and completely encasing the electrical connections inside the unit? Then, if/when the leak occurs, the electrical connections would be protected from the spraying water... hmmm

Also, what does the 'R' in the RCB acronym, stand for? Just curious. I'm asking because I have installed a thermal type circuit braker prior to my HW heater... same as I have prior to my A/C unit.

A residual current device (RCD), or residual current circuit breaker (RCCB), is an electrical wiring device that disconnects a circuit whenever it detects that the electric current is not balanced between the phase ("hot") conductor and the neutral conductor. Such an imbalance is sometimes caused by current leakage through the body of a person who is grounded and accidentally touching the energized part of the circuit. A lethal shock can result from these conditions; RCDs are designed to disconnect quickly enough to mitigate the harm caused by such shocks.

In the United States and Canada, a residual current device is also known as a ground fault circuit interrupter (GFCI), ground fault interrupter (GFI) or an appliance leakage current interrupter (ALCI). In Australia they are known as "safety switches".
