If you're handy and know the rules about electricity well enough to make mains powered stuff that won't kill people, you can make a power controller using those electric cooker power controllers. I think they are called 'simmer stats' or something of the sort. A stirdy insulated project box with a power socket mounted on it and a simmer stat in it with a knob on the front with a power cord coming out the back ending in a nice three pin plug would do the trick Cwrw. You can plug in teh lead and then plug your Ace into the socket with the simmerstat in between. That should control it fine. Those simmer what nots can control a big fat ring on an electric cooker so you can surely find one to manage your 1.6KW element. Mine is 2.6KW or thereabouts and it boils like some torture vat in Hell. It is almost volcanic during the boil, especially when you get the hot break and for a few minutes after putting in the Protoflock stuff.
Cheers Tony, I'll have to look into that. Mine too boils like a volcano and I'm often misjudging my volumes so it's pretty damn full as it comes to the boil - haven't had a full boil-over for a while though.:
Ok I've ordered one - looks easy enough to wire up.
