Indirectly fired Fast Boiler tank CAWT-300L Duplex 2205 300 liter with coil (Spiral) For heat pump

CAWT-300L Fast Boiler Tank – 300 Liter Stainless Steel Boiler with Spiral for Heat Pumps

The CAWT-300L Fast Boilertank is the solution for modern heating systems where energy efficiency and hot water comfort are paramount. This indirectly fired stainless steel boiler tank of 300 liters has been specially developed for use in combination with heat pumps and other sustainable energy sources, such as solar boilers or hybrid installations.

What sets this boiler apart is the use of Duplex 2205 stainless steel – a high-quality alloy that provides optimum corrosion protection, a longer service life and excellent hygienic properties. Thanks to this material, the tank can withstand high temperatures and pressure, making it extremely suitable for long-term, demanding applications.

The tank contains a powerful spiral heat exchanger (coil), which efficiently heats the water using an indirect heating principle. This heat exchanger is optimized for low-temperature systems such as heat pumps, and therefore guarantees high heat transfer with low energy consumption.

With a net capacity of 300 litres, this Fast Boiler is perfect for medium-sized households, apartment complexes or small-scale utility buildings. Thanks to its horizontal design, the CAWT-300L is particularly suitable for technical rooms with limited height or where vertical placement is not possible.

The high-quality PU insulation around the tank prevents heat loss and ensures maximum energy efficiency. In addition, the boiler is equipped with multiple connection options for easy integration into various heating systems.

✅ Key benefits:

• 300 litre capacity – perfect for medium hot water requirements
