First I should state that I am (was) an electrical engineer, although more on the electronics side than heavy duty electrics. I've lived in Bangkok at the same apartment for 13 years. The bathroom heater started giving shocks to the maid. The landlord called in a specialist company who discovered the heaters weren't earthed (grounded). Then the whole apartment wasn't earthed. Yes the heater had one of those Thai plastic circuit breakers in the shower area. Horrifying! First get a professional electrician to check your earth connections. (How to find a PROFESSIONAL in Thailand I have no idea). I If I were leaving for a period of time, I'd unplug any appliances (knowing the state of Thai wiring). Lastly, although this thread contains a lot of useful advice, don't take any advice on electrical, medical or legal advice from forum threads or bar-rooms (ESPECIALLY MY ADVICE).

farcanell Posted January 3, 2017 Share Posted January 3, 2017 (edited) I reckon turn it off when not in use.... my systems starts sending a warning alarm if the unit is not turned off after the tap is closed. also.... I have just had an "electrician" here to troubleshoot circuit breaker loading, in that I'm getting load on two water heater circuit breakers, which are in the spare bedrooms, and never used... and turned off! electrician said to call him back if the circuit breaker started to trip.... lol.... right... so obviousely I simply flicked the circuit off. attached is a pic of a broken circuit breaker, that I noticed recently... it was still live, and powering a bench-saw! i was a bit too scared to get closer, for a better pic, but they orange spot in the middle (RHS of melted fuse) of the pic is where the current was jumping across metal components on either side of the "circuit breaker" do not trust thai wiring! Damn... my stove heard that.... now it's started shocking me! Edited January 3, 2017 by farcanell Link to comment Share on other sites More sharing options...

Peterw42 Posted January 3, 2017 Share Posted January 3, 2017 (edited) I have a shower unit with an on/off switch and left on it generates a small amount of heat, enough to notice in the morning if its been on all night and the bathroom door is shut. I read somewhere that its allways a good idea to turn it off and run the water until cold. I would have thought the same, no water flow its not on, but maybe the coil/element is energised a little to prolong the life of the unit.

12DrinkMore Posted January 3, 2017 Share Posted January 3, 2017 Apropos. The water where I live is extremely hard. Is it possible to remove the build up of deposits inside the heating unit? I think this is one of the reasons why my units give up after a few years. Link to comment Share on other sites More sharing options...

Depending on your plumbing arrangement, you might be able to introduce citric acid, or some other fluid, like vinegar, into the heater, and let it steep for a couple of hours washing machines or dishwashers are easier to fix, as they recirculate the same treated water for a time, which is why I can only suggest trapping a cleaning agent within the heater and letting it steep. rinse and repeat.... you might also want to remove the shower head to allow any particles free exit, as some shower heads and tap openings, have wire mesh filters... lose of pressure is sometimes indicative of blocked mesh you could also consider installing a decent water filtration system, to slow down the build up in future best of luck Link to comment Share on other sites More sharing options...

SOUTHERNSTAR Posted January 3, 2017 Share Posted January 3, 2017 Don't worry too much about the wiring inside the unit, the problem is the lack of insulation where the units wires are attached to the houses wiring. Most unit are well insulated and don't cause problems. We have moved out of hotel rooms due to open wires (no insulation) in showers, no earth wires and open non water proof electrical switches.

The fuse wire has not blown and the knife is in the on position so still usable. Obviously not the best example of safe wiring. Below is how it should look taken apart.

gk10002000 Posted January 4, 2017 Share Posted January 4, 2017 On 1/2/2017 at 3:47 PM, Crossy said: Yup^^^, cannot disagree. Our OP says "... boxes above the shower where you can adjust the temperature ..." so I assumed that it is the shower unit itself which he wants to turn off (ours has an 'off"position on the temperature dial). If it's a separate switch then no way would one want to touch it with wet hands whilst standing in water. I recommend a big blob of paint on rubber stuff you can get at any hardware store, like the stuff you can coat tool handles with. I mean really make it so your hand really is isolated from the box or mounting, even to the point of gluing on some bigger looking handle that is non conductive Link to comment Share on other sites More sharing options...
bubba Posted January 4, 2017 Share Posted January 4, 2017 ...or better yet, get a gas hot water heater, if you are able to mount one on the outside. No worries about bad and potentially dangerous electrics, plus with the cold ambient temperature of water in the winter, you actually get a hot shower with lots of water, rather than the trickle that you might get with some electric heaters. I would guess that the energy cost is less as well. Link to comment Share on other sites More sharing options...

It costs nothing to turn it off if you want. In my family it is fear of lightening (or a major short out in a transformer pole, or car/vs/transformer pole-accident) frying the appliance. But they do not turn fridges off. Pretty much everything else, all the time. Particularly if I am backing up the entertainment system computer in the day room. GRRRRRRRR!!!!!!!!

Grubster Posted January 5, 2017 Share Posted January 5, 2017 I adjust mine while in the shower to control the heat. the unit is always dry and the knob is plastic so I am not afraid of it at all. I am mare afraid that poor workmanship inside the unit could allow electric current to come in contact with the water. Link to comment Share on other sites More sharing options...
