Whole House Recirculation Diagram with an Ariston Mini Hot Water Tank


Avoid long pipe run from the Tankless Water Heater to the Ariston Hot Water Heater. 

Any Tankless Water Heater will work and we recommend using an Ariston GL4 or GL6+.

Timed operation is suggested. Mini tank remains heated at all times while circulator pump can be programmed with a timer to circulate in early morning hours and evening, when demand is greatest. Also, cold water plugs will be eliminated with this method when using the proper size tank with a tankless water heater.
