As far as the water temperature is concerned, you get to choose from 80-150 degrees Fahrenheit.

After 20 minutes of continuous operation, this tankless water heater will shut off automatically. As long as you have 20-100 PSI of water pressure going into it, it will function properly. Another thing that makes this portable unit great, is that when the power is out, you’re still guaranteed hot water.

How? The two D batteries provide a spark to ignite the flame that heats the water, thereby eliminating the need for a standard outlet hookup.
