Hydraulic module Easyflow Logic direct circuit, mixing circuit hot water charging

Heating and hot water system design

• For condensing boilers with a mixed and unmixed heating circuit
• Optimal condensing boiler utilization and energy savings, as the high return temperature of the radiators is mixed with the flow temperature of the underfloor or wall heating, thus cooling the overall return temperature sufficiently to ensure condensation always occurs in the condensing boiler.
• Easy mounting thanks to stable metal base plate
• Lower investment and operating costs, as one pump in the direct circuit is no longer needed (heating unit pump is used).
• Compact and fully pre-assembled
• Fully pre-wired (in the version with control)
