My electricity woes are back. Our 3KW V Guard storage water heater just burnt the socket and plug.



We have a DB board with MCBs and recently I installed overload protection. It is a rented house. Should I install local protection at the Geyser line level so that this melting of wires and sockets can be avoided? Do I need a RCCB or RCD device at full house level to prevent this? I don't know why the heat in the line didn't trip the MCB on the DB or whether it is even actually meant to?

The problem is the socket/plug interface. If it is slightly loose, sparks will cause the damage you see. See if you can install the Compton-Greaves metal socket/plug set. That is what we use for all our AC's.

I have good experiences with Daikin - and their track record till quite recently in India is as providers of HVAC for factories. Good, robust and well engineered ACs. Premium price though.

@diyguy; @Aroy is correct. There are many plugs in the market with single piece pins (Northwest & Crabtree to name a couple) of brass. These do not have this problem. I never faced this once I switched to NorthWest. The common ones have two pice pins which screw into one another. Incidentally, NW also have 25A plugs and sockets. The matrix is identical to the 16A but the pins are longer. For the past decade I have not used any plugs except for these two (90%NW) in my house, other than premoulded ones of course.

@sgiitk and @Aroy, thanks for the responses. Is such a device a deterrent and can it prevent loose contact based sparking and potential damage/hazard?

In our new home, the builder has not provided any arrangement for window AC but has provided requisite 3" hole for split setup.

I recently visited a famous ELECTRONIC store here and they offered VIDEOCON VSD55WV1 (FIVE STAR) for 26.5K.

How is VIDEOCON in AC segment??

Raab rakha.
P.S.: I presently have HITACHI window AC, which is noisy when compressor stops (window shudders) :-)

What happens the pin and the inside part which are screwed into one another become loose, and then sparking leads to what you have witnessed. Of course with a one piece pin this does not happen and this guards against a lot of problems. As I said since I switched to NW or Crabtree I have had to plug (or socket) failures.

I wanted to know about the particular AC, not the brand, I am OK with brand.
There is huge saving of up to 10 to 15 thousand rupees on Kenstar 1 ton 5* AC, EER of 3.5 is also ok

I have two Videocon Window units dating back to 1999-2000. They are still doing good. We also had a Videocon 2T Split. That was not so happy. the compressor (recip) had to be replaced after about 1-1/2 years and I had repeated problems with a temperature sensor. Finally, I replaced the Indoor unit with a Voltas and was happy. Then we replaced the system with a Daikin 2TR R401a unit. After an initial gas leak, during the first year (fixed under warranty) it has been going strong for over three years. There is a massive drop in our electricity bill after thi replacement.

I will try and avoid brands like Kenstar. In any case make sure the coils are copper.

Thanks for your suggestion.
Have found VOLTAS to be quite efficient and as per various net ratings found out that it has the lowest power consumption against other models with similar or even better coolling performance.

Raab rakha.

Voltas has always been a paper tiger. As I have said earlier it is like buying a lottery, some batches turn out great most others not so much.

I will not be surprised if they are sourcing the units (esp Inverters) from China. I used to be a Voltas fan (I had a B1G!) but then moved on. They were better than many others but by and large were not efficient. Now all of a sudden they have a new range, and the new ones are claiming excellent EER figures!

All weather ACs have been in the market for quite some time, in Delhi every forthcoming winter is getting unbearable now. OGeneral has launched all weather unit. I'm planning to buy one, can somebody, share their experience and most importantly bill and maintance part.

Does Heater part works on the concept of Oil Heater?

I do not think so, there will be coil for heating. Better to get oil heater with more functionality
