More than 100 years ago, Edwin Ruud, a Norwegian mechanical engineer, came to America and developed the first successful automatic water heater. That early success marked the beginning of a tradition of innovation and value that led to the introduction of RUUD heating and air conditioning equipment in the 1950s.
Since then, the RUUD has grown into one of North America’s largest manufacturers of quality heating, cooling and water heating products for residential and light commercial use.
Today, RUUD operates manufacturing facilities employing highly trained workers and state-of-the-art equipment. Over the years, the product lines have expanded, changed, and improved significantly as new design techniques and better manufacturing technologies have become available.
What remains unchanged throughout our history, however, is our commitment to producing the most reliable, long-lasting, efficient equipment you can buy.

There’s just no limit to the usefulness of instant hot water.
Making tea & coffee is just the start. With an instant hot water dispenser, there is a near limitless list of uses for near-boiling water that’s ready all of the time.
Things like getting a head start on recipes. Washing baby toys & equipment. Even cleaning up around the kitchen is faster & easier than ever before. Nearly every day that goes by you’ll find a new use for near-boiling water on demand. And, nearly every day you’ll wonder how you ever got along without it.
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.
