I think this dual unit is awesome but it takes 20 to 60 mins to heat up. My question is; how long, once the heater is turned off does the water stay warm? It heats up 11 liters so if it is well insulated it could maintain the water temperature a little bit. It would be nice to heat it up, go on a hike/fish/ski and then 4 hours later there is still water that is still warm enough to use. I understand it has a lot to do with external temperature and where the unit is located.

Where can I purchase this unit
With the digital unit, could you make adjustments for altitude?
