I picked up one of these Zojirushi hot water pot with stainless steel vacuum flask within (they called it "VE hybrid") from a local thrift store, it's very efficient I must say:
Amazon.com: Zojirushi CV-DSC40 VE Hybrid Water Boiler and Warmer, Stainless Steel: Electric Hot Pots: Kitchen & Dining
Mine has all the essential features such as various temp control, de-chlorine (a timer set boiling for 3 mins before turning off the heating element), timer (can set to delay the re-heating by up to 8 hours, so as to conserve energy).
I think if hot water (for drinks) is what you want, this may be another option for you.
Just a thought on the subject.
