This could be another one for Nereus!!
I’ve previously looked here in Thailand for an electric kettle with a 3kw heating element, but the majority seem to be rated at just 1.8kw, so a kettle takes an age to boil. Whilst I was back in the UK, I bought a 3kw kettle and “smuggled” it back in my suitcase. Now although I didn’t time it in the UK, I’m absolutely certain that it boiled a given quantity of water faster than it does here in Thailand - I can’t think of a plausible explanation (other than my mind is playing tricks with me) - can anybody suggest something?

Re: Electric Kettles
Assuming that your supply is constant at 220 volts, there should be no difference.
Low power in Thailand is quite common. I suggest you check your voltage.
BTW 3 KW kettles are readily available here online.

Ohms law:
Ohm's Law is a formula used to calculate the relationship between voltage, current and resistance in an electrical circuit.
Where you are the voltage may only be 220 volts at its best. In the UK it was probably around 240 volts.
Your kettle is a pure resistance, so the watts that do the heating is: volts x amps = watts
Watts Law also states that the power of an electrical circuit is the product of its voltage and current.
So volts less = less watts (pure resistive circuit only), so to get the same amount of heat, or BTU's, it is going to take longer.

My wife said to consider yourself fortunate, you can go back to Britain, while Thais have to stay here and suffer, waiting for their water to boil.

Re: Electric Kettles
Thanks - I’m sure that the voltage will be the reason - I don’t have the means to test what the actual voltage is, but in any case, the new kettle does boil quicker than the old one, so it’s a step in the right direction.Nereus wrote:Ohms law:

Re: Electric Kettles
It's taking longer because you are at sea level.
Next time your ready for a quick cuppa, head to Chiang Mai
