Condensing gas boiler MCR3 Evo 35T/SRK150 with DHW heater. 7716671150K

Modern heating and domestic hot water in one package

This package includes a high-efficiency De Dietrich MCR3 Evo 35T condensing gas boiler, combined with a 150-liter (SRK150 model) enamelled DHW tank. This comprehensive solution provides thermal comfort in your home all year round, both in terms of heating and access to hot water. The boiler is distinguished by its compact dimensions – only 370 x 550 x 360 mm and weighing 25 kg – which makes installation easier even in limited spaces.

The boiler is factory set to operate with natural gas, but can be adapted to propane without any additional modifications. Thanks to C10, C13, C33, B23p, C93 and C43 and C53 approvals, it offers great flexibility in terms of connection to various flue systems and exhaust gas removal – both traditional and modern. Efficiency at even 110.4% (at 80-60°C) translates to lower heating bills and a reduced environmental impact. Low NOx emissions (below 60 mg/kWh) is another argument for choosing this model.

Construction and key features

The heart of the boiler is a compact heat exchanger made of aluminum-silicon alloy. This material is characterized by high resistance to scale formation, which ensures long-term device performance – this is confirmed by an 8-year warranty on the heat exchanger. The air/gas module with a modulating burner (24-100%) ensures precise adjustment of power to current heating needs, and the air intake silencer minimizes noise during operation. The hydraulic module includes a modulating pump of class A, a CH/DHW switching valve, a CH safety valve and a flow limiter. An expansion vessel with a capacity of 8 liters is integrated with the boiler frame.

The control panel with a clear LCD display allows easy setting of operating parameters and access to the service menu. Cooperation with modulating or on/off room thermostats is possible, and the boiler can optionally be connected to the Wi-Fi network using the SMART TC° thermostat, which allows remote control and monitoring of the heating system. The SRK150MG DHW tank has a 1/2” drain valve and a 6 bar 1/2” safety valve. It provides efficient water heating thanks to a heat exchange surface of 1.14 m².
