Condensing gas boiler, MCR3 evo 35T/AQUAvie125 + iSense package 7716671125AQVIS

Modern heating with the De Dietrich MCR3 evo 35T + Aquavie125 package

This package combines high efficiency and comfort. The De Dietrich MCR3 evo 35T condensing gas boiler, paired with the Aquavie125 hot water tank, is the ideal solution for both new installations and the modernization of existing heating systems. Its compact dimensions and ease of installation make the boiler suitable even for limited spaces. The set is designed for reliability and low operating costs.

Performance and savings

The MCR3 evo boiler utilizes condensation technology, meaning it recovers heat from the flue gases, increasing energy efficiency to up to 110.7% at 30% load. This translates to lower gas bills and a reduced environmental impact. High seasonal heating efficiency of 94% guarantees optimal energy consumption throughout the year. The compact heat exchanger made of aluminum-silicon alloy is resistant to scale formation and is covered by an 8-year warranty. The modulating gas burner adjusts the power to current needs, further increasing savings.

User comfort and flexibility

The set offers not only efficient heating but also comfortable domestic hot water thanks to the Aquavie125 tank. The boiler is factory-set and ready to operate with natural gas, but can be adapted to propane without additional costs. The ability to connect to various flue gas systems (C10, C13, C33, B23p, C93, C53, C43p approvals) provides installation flexibility. The control panel with a clear LCD display allows easy setting of the boiler operating parameters. Additionally, remote control is possible via the SMART TC thermostat through Wi-Fi – a convenient solution for those who appreciate modern technologies.

Construction and installation

The compact dimensions of the boiler (368 x 541 x 364 mm) and its low weight (25 kg) facilitate transport and installation. The set includes a hydraulic connection cover and a boiler-DHW tank connection kit, which speeds up the installation process. The hydraulic module contains a modulating pump of class A and a central heating/DHW switching valve, ensuring optimal operation of the heating system. An expansion vessel with a capacity of 8 liters mounted on the boiler frame stabilizes the pressure in the installation.
