In this video you will see how we boil water with an immersion heater inside a thermos flask.
This is an option for us that works well with a relatively low power consumption as the heater only uses a 1000W. 
Boiling a liter of water at around 20°C (68F) takes around 5 to 5.5 minutes. The heater costs around 25 EUR (25 CHF or 22 GBP).
