Concept / Description

ATAG IC Economiser Plus is a sophisticated module engineered to enhance the efficiency of condensing boiler systems. It operates by recovering waste heat from flue gases—heat that would otherwise be discarded—and redirecting it into the heating circuit. The product is composed of several interdependent components that work in unison to achieve this goal:

• Flue Gas Recovery System: Captures excess heat from flue emissions using a network of sensors and heat exchangers. This system is calibrated to monitor the temperature and flow of exhaust gases, ensuring that heat recovery is optimised in real time.
• Modulation Algorithms: Advanced control algorithms adjust the operational parameters of the economiser based on dynamic environmental and system conditions. These algorithms enable the module to maintain an optimal return water temperature, which directly influences boiler efficiency.
• Heat Exchanger Design: At the core of the unit is a high-efficiency heat exchanger that transfers recovered heat from the flue gas to the potable water in the heating circuit. The exchanger is engineered for maximum thermal conductivity while minimising heat loss.
• Integrated Sensor Suite: A collection of temperature sensors, flow metres, and pressure gauges continuously monitor system performance, allowing the module to self-adjust and maintain stability.

Together, these components create a system where energy is conserved during operation, contributing appreciably to lower energy consumption and improved system longevity. The design supports integration into a wide variety of heating systems, from single-family homes to large commercial installations.
