I buy a water heater made by china company.they give me warrenty 2 years but I fit this in my bathroom only 5 days it will work good but after 5 days one day sparkels happen in that water heater.wire of that heaters are burn.
my godness is that I fit mcb in my homes it help to automatic cut the power supply and my home saved by shot circuit.
