Condensing gas boiler MCR3 Evo 30/35MI dual-purpose 7716673A

Condensing gas boiler – efficient heating and domestic hot water

This dual-function condensing gas boiler MCR3 Evo 30/35MI is an advanced heating solution, combining high efficiency, compact dimensions and versatile applications. The device is factory pre-set, which simplifies installation and ensures optimal operation immediately after start-up.

A key feature of this model is its high efficiency, reaching up to 110.4% in condensing mode. This means that the maximum amount of heat is obtained from each unit of gas consumed, which translates into lower heating bills and a reduced environmental impact. The heat exchanger made of aluminum is characterized by exceptional resistance to scale formation, and the manufacturer provides an 8-year warranty on it – a solid argument for choosing this model.

Compact dimensions (370 x 550 x 360 mm) and low weight (25 kg) make installation easier even in limited spaces. The boiler is adapted to work with both natural gas and propane – changing the fuel does not require additional conversion kits. The ability to connect to various flue gas systems (horizontal, vertical, chimney, distributed or collective system) provides installation flexibility and adaptation to individual conditions in the building.

Advantages for installers and users:

• High efficiency: Gas savings and lower operating costs.

• Compact dimensions and low weight: Simplified installation even in difficult conditions.

• Fuel versatility: Ability to operate on natural gas and propane without additional costs.

• Installation flexibility: Wide possibilities of connection to various flue gas systems.

• Durable construction: Aluminum-silicon heat exchanger resistant to scale with an 8-year warranty.

• Low NOx emissions: Environmentally friendly – emissions below 60 mg/kWh.

• Burner modulation: Modulation range from 24 to 100% power provides precise adjustment to the heat demand.

• Built-in safety features: Central heating safety valve, flow detector ensure safe operation of the device.

• Remote control possible: Compatibility with SMART TC° thermostats allows you to control the boiler via Wi-Fi using a smartphone or tablet.

The boiler is equipped with a hydraulic module with a modulating pump of class A and a plate heat exchanger made of stainless steel for the production of domestic hot water with a capacity of up to 18.9 l/min (at Δt=25°C). A clear LCD display on the control panel makes operation and monitoring of the device's parameters easier. An expansion vessel with a capacity of 8 liters is mounted directly on the boiler frame, which further simplifies installation.
