How use a Recirculation Pump for a Tankless Water Heater using an Ariston Mini Hot Water Tank

SAVE ENERGY and SAVE WATER! 

Avoid long pipe run from the Tankless Water Heater to the Ariston / Bosch 300T Hot Water Heater. 

Any Tankless Water Heater will work and we recommend using an Bosch 3000T - formely 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.

This diagram is for reference only. Always refer to the manufacturers installation manual for exact information.

This is just an example. Actual layouts vary from job to job.
