Condensing gas boiler MCR3 Evo 24T/SRK100 with DHW heater. 7716670100K

Modern condensing heating – MCR3 Evo 24T/SRK100 boiler

This condensing gas boiler combines high efficiency with compact dimensions. The MCR3 Evo 24T model, together with the SRK100 hot water tank, is an ideal solution for both installers looking for reliable equipment and users who value comfort and savings. The boiler is characterized by a modern design and ease of installation, and its efficiency exceeds 110%, which translates into lower heating bills.

Efficiency and versatility in one

The MCR3 Evo 24T boiler utilizes condensation technology, which means it recovers heat from flue gases, increasing combustion efficiency. The heat exchanger made of aluminum is exceptionally resistant to scale build-up – the manufacturer provides an 8-year warranty on it. The device is factory set to operate with natural gas, but it can be adapted to propane without additional costs. The ability to connect to different flue gas systems (chimney, separate or collective system) provides great freedom in choosing the installation.

• High efficiency: up to 110.5% / 100% – minimizes heating costs.
• Compact dimensions: 370 x 550 x 360 mm and weighing only 25 kg make installation easy even in limited space.
• Versatility: possibility of connection to different flue gas systems (C10, C13, C33, B23p, C93, C53, C43 approvals).
• Durable construction: aluminum-silicon heat exchanger with an 8-year warranty ensures long-lasting and trouble-free operation.
• Low NOx emissions: meets stringent environmental standards (below 60 mg/kWh).
• SRK100 tank included: provides constant access to 100 liters of domestic hot water. The tank is protected against corrosion by a magnesium anode.

Construction and operating parameters

The boiler is equipped with a modulating gas burner with a range of 24 to 100% power and a circulation pump of class A. The hydraulic unit contains a central heating/domestic hot water switching valve, a safety valve and a flow limiter. The expansion vessel with a capacity of 8 liters is mounted directly on the boiler frame. The control panel with a clear LCD display allows easy setting of operating parameters and access to the service menu. The device can cooperate with modulating or on/off room thermostats as well as with SMART TC° thermostats via Wi-Fi.

• Nominal power (80-60°C): 23.8 kW – provides sufficient heating power for most single-family homes.
• Nominal power (50-30°C): 24.8 kW – high efficiency even at low outdoor temperatures.
• Electrical power supply: 230 V/50 Hz – standard mains voltage simplifies electrical installation.
• Protection class: IP X4D – resistance to splashing water and dust ensures safe operation in various conditions.
