Does anyone have statistics on the typical costs in Baht of using various household electrical goods. I am particularly interested in how much it costs to boil a full pot of water in a standard sized kettle.

Electricity is about 4 Baht a unit including taxes and fuel surcharge if bought off the authority (if you're in a condo then the sky's the limit).

1 unit is 1 kWh or 1000 Joules per second x 3600 seconds in an hour = 3,600,000 Joules

Specific Heat Capacity of water is 4200 J/kg/C

If your pot holds 1 Litre (1kg) and the water is 25C from the tap then you will use 4200 x 1 x 75 = 315,000 Joules to heat that water to 100C.

So to boil that pot used 315000/3600000 = 0.0875 units or 0.35 Baht.

Add to that the power used whilst the water is boiling waiting to be turned off

Assuming no losses and that my memory of schoolboy physics hasn't been addled in the 35 years since it was last used

Crossy you are the man ! :jap: :jap:

If ever you fancy a few days in Samui doing a bit and a holiday to boot let me know as trying to get any sense electric wise here is a joke.

Crossy, Wow...you are way too smart....seriously. Good info. Cheers.

I second that. Thanks Crossy

555. I just read what I wrote, looks like the sort of thing I wrote 35 years ago in my O level Physics exam. Perhaps I'm regressing to my childhood.

Hmmmm, couldn't be too bad, I could have another shot at the girl next door, Yvonne, blue eyes, blonde hair, big bazookas

We said you are still smart; not necessarily still handsome.
