Hydraulic module Easyflow Logic 1

Heating and hot water preparation design

• For condensing boiler systems with a mixed or unmixed heating circuit
• Optimal condensing technology utilisation as the radiator’s high return temperature is mixed into the underfloor heating or wall heating system’s flow, and thus the total return is cooled down to such a point where condensation always occurs in the condensing boiler
• Simple fixing due to stable metal base plate
• Lower investment and operating cost as a pump in the direct circuit is not required (a heating device pump is used)
• Compact and fully pre-assembled
• Fully pre-wired (in the design with control system)
