Product information
Efficient and corrosion-resistant for modern low-temperature boiler systems
The same DW ECO 2.0 platform also provides an excellent solution for gas condensing and standard pressurised boilers operating at lower flue gas temperatures. When equipped with the appropriate H1-class sealing joint, the system achieves P1 pressure class and W-class moisture resistance, making it fully compatible with condensing technology.
The DW ECO 2.0 316 version, featuring an AISI 316L stainless steel inner liner, is specifically designed to withstand the acidic condensates typical of condensing gas appliances. It is certified for use in systems with flue gas temperatures as low as 120 °C and includes a dedicated condensing joint seal (DW2526C) for airtight performance.
This makes DW ECO 2.0 a highly flexible solution for both new and retrofit installations in commercial buildings, where space, efficiency, and compliance are key.
