electric hotplates
Posted: Wed Dec 05, 2012 9:16 pm
tested out my electric hotplate tonight.
its a cheap 2 element portable type thing - this one http://www.productreview.com.au/p/breville-hot-top-2.html
from my calcs on how much vapour its producing - Im only getting out about 300 watts!! not including heat losses from the boiler and column both of which are insulated.
Any one else used something like this?
I know it has a rheostat and before actually using it figured that the max setting would be maximum power
(ie no 'off time') but i can hear the rheostat switching on and off even at full power -- Im guessing this is either a safety measure as the crappy device cant actually safely output 1600 watts or its just a design fault. Im considering just bypassing the rheostat - already have my controller wired up anyway.
thoughts?
