So getting to the stage where I need to get a heater for the 220 so I can get it going. Needs to be able to heat a total water volume of about 300g. I am thinking that titanium will be the way to go, unless anyone can tell me otherwise. Any ideas on wattage and/or brand, single versus mulitple heaters... etc. etc etc. I do have a ranco dual stage temp controller that will be used in conjunction with the heater(s).
