"The Ariston products specify the recovery rate - 'temp. rise' based on the GPM flow; what do you mean by this?"
Temperature rise is the amount the heater raises the temperature of the incoming water, based on the flow rate shown of that water.

"Can any of the Ariston models be used on the hot side of the plumbing? My hot water heater takes a minute or two to reach several sinks, wasting time and water. I want to put a small tanked water heater in-line on the hot side."
Yes, any of the Ariston models can be used for that application.

"Do these Ariston water heaters have drain valves?"
No. These units are small enough to disconnect and drain into a sink if desired.

"Do the Ariston heaters have to be hard-wired?"
The 2.5 and 4 gallon models plug into standard 110 volt outlets, while the 8gal model requires hard-wiring.

"The truth is cruel, but it can be loved, and it makes free those who have loved it." - George Santayana
