cold spell and electrified water

it has been cold of late.

intriguingly, metro manila and tagaytay have low temperatures separated only by one degree these days. imagine that. tagaytay ridge temperatures right here in the metro (both in makati and here in las pinas), add wind chill and it gets even colder.

therefore: get a plug-in drop-in-bucket type water heater. i had not paid close attention to these gadgets, having gotten a red one (deep well type) at the start of the stay in the las pinas apartment. after a while, i had taken it to makati, and had always wondered if it really took 20 or so minutes to boil 3 liters of water...

and now the cold spell, and a need for heated water in the mornings here in las pinas. so, another red one was purchased, and the effect was, well, electrifying.

not that i got myself electrified or anything like that, but the way the device worked was worth some description. either that or the particular unit i purchased, within the bounds of manufacturing variability, was more different, somehow.

instructions for use: plug in, and then dip in water-filled bucket.

plug in: it began to hum. eh? i didn't recall that of the first red one.

dip in bucket: the entire bucket began to hum deeply, kind of like the noise made by those large-ish transformers that metalworking shops use to power arc welders. ?!

add to that, crackling, popping noises within the device itself, and a readily apparent flow of heated water.

hmm. and a bucket of boiling water in 6 minutes. well, about 3 liters worth of water in a bucket.

interesting.

now to try and see whether the "nawasa" type will do a similar water electrification act in makati.
