The CAWT-300L Fast Boiler Tank is the ideal solution for modern heating systems where energy efficiency and hot water comfort go hand in hand. This 300-litre indirectly heated stainless steel tank is specially designed to work in combination with heat pumps and other renewable energy sources such as solar thermal or hybrid installations.
What sets this boiler apart is its construction from Duplex 2205 stainless steel – a premium-grade alloy that provides exceptional corrosion resistance, a long service life, and excellent hygienic properties. The material ensures the tank can withstand high temperatures and pressure, making it ideal for intensive and long-term use.
Inside the tank is a high-performance spiral coil heat exchanger, which transfers heat efficiently through indirect heating. Optimised for low-temperature systems like heat pumps, the coil ensures excellent heat transfer with minimal energy consumption.
With a net capacity of 300 litres, the CAWT-300L is perfectly suited for medium-sized households, apartment complexes, or small commercial applications. Thanks to its horizontal design, it’s also ideal for technical rooms with limited ceiling height or where vertical placement isn’t feasible.
The tank is surrounded by high-density PU insulation, which reduces standby heat loss and ensures maximum energy savings. Multiple connection points make it easy to integrate into various heating system configurations.
