Nexus PDWT 300H+100 2-in-1 Stainless Steel Heat Pump Boiler with 100L Buffer Tank

The Nexus PDWT is a 2-in-1 stainless steel solution for heat pump systems: a domestic hot water boiler is positioned above a 100 litre buffer tank. This tank-on-tank design combines shower water storage and heating system buffer volume in one compact product.

The upper Duplex 2205 stainless steel boiler is designed for sanitary hot water production, while the lower AISI 304 buffer tank increases system water volume and improves hydraulic stability. This helps reduce frequent heat pump cycling and supports smoother operation of the heating installation.

The integrated AISI 316L corrugated heat exchanger transfers heat efficiently from the heat pump to the domestic hot water section. The separate buffer section below is ideal for installations where space is limited but both DHW storage and buffer capacity are required.

With Energy Label A, PU insulation, sensor pockets, electric backup connections and a frosted-metal outer casing, the PDWT series is built for professional installers who need a clean and space-saving buffer plus boiler solution.
