Heating water

[Carlo09]

Ok so I have some vinegar and Bicarb and want to generate an exothermic reaction, but just mixing them produces co2 in an endothermic reaction! How can I do this? Thank you.

Ok I have an idea, Mixing bicarb and vinegar produces sodium acetate solution in water. Concentrating this by boiling off the water and then maybe making a handwarmer type solution ... supersaturated sodium acetate solution and then cause it to crystalise to heat the water? Could it work using basic lab equipment?
