Eemax

The Best Technology Period. It's Simple Physics
Eemax’s Direct Heating Technology blows away other water heating technologies.

Direct Heating Elements transfer heat directly to the water, heating it faster, and giving you hot water when you need it. The lower thermal mass means it adjusts faster, giving you consistent temperature. It instantly shuts down when you’re done and cools faster, causing minimal overshoot, and no energy being wasted.
