The amount of water in the tank simulates the weight of the boat and crew, the more water in the tank the heavier the boat and crew. The standard Calibration Level is Level 17. If the user is lighter in weight, Level 15-16 can be used. If the user is heavier in weight, level 18-19 can be used. The maximum level to fill the tank is Level 19. DO NOT fill above the maximum level – this could void the warranty.

The reason I'm writing now, two years after purchase, is, I broke one of the wheels. I proceeded to order the wrong replacement, so I emailed them pictures to ask for the right parts. They wrote back asking for the serial number to get the right unit AND to see if it was under warranty. (Hadn't even occurred to me.) Turns out it was, they're sending me the wheels, they're refunding me for the wrong part, AND included a link for the Puri-Tabs which I didn't know they provide for the life of the ROWER! They're also replacing all eight wheels even though there's only one broken one.
A 125-pound person moving at an average pace for 30 minutes on a treadmill will burn roughly 250 calories. However, they aren’t able to take advantage of this after-burn effect. The same person rowing vigorously will burn around to 250 calories but will have less stress placed upon their joints and continue to burn calories after the workout has ended. Rowing machines have been shown to burn on average 800 calories an hour if you work harder and are slightly heavier.

The frame is beyond durable and is designed for absorbing sound and vibration. There’s no creaking or other sounds that you might expect from wood components. It has a low center of gravity that keeps the rower in place while exerting full rowing power. The polycarbonate water tank is equally durable and practically indestructible. The Classic Rower doesn’t have any moving parts that can wear out, or belts and pulleys that need to be maintained.
The model E’s seat stands 6 inches higher. And while the model D’s monitor rests on an adjustable arm, the E’s sits on unbending metal. These few technical differences do nothing to impact ride feel. We recommend the $200-cheaper model D as the best buy, but the Concept 2 E will appeal to anyone who values a higher seat and more solid construction.
The WaterRower Natural is handcrafted from solid Ash wood, finished with a honey oak stain and danish oil. The WaterRower's patented WaterFlywheel has been specifically designed to emulate the dynamics of a boat moving though water and is unsurpassed in its simulation of the physical and physiological benefits of rowing. WaterRower will not provide support or documentation for any product transported outside of the original country of purchase
