Sure, Mella
The difference is the volume. It will take much longer to fill a tub, and you may not be able to use two or more hot water appliances at the same time. An on-demand hot water heater may only produce 2-3 gallons / minute at a 90 degree temperature rise, while you may be able to get 6 to 8 gallons a minute from a tank-type water at whetever temperature it is set for. For most applications this won't be a bother, but if your trying to fill a hot tub, it will take much longer. Generally, when shopping for an on demand type water heater, the larger and more expensive units are able to produce a higher volume of water per minute. My Paloma at the cabin works fine for showers and the kitchen sink, and produces .7 gallons per minute of water at a 100 degree temperature rise. This equates to 140 drgree water if the incomming is 40 degrees...the volume will be greater with your warmer water.
Hope this helps... they really are the way to go if the goal is to save energy.
