Add authentic steam power to your model boat with the RW-B2 Vertical 500mL Copper Steam Boiler. Designed for medium-sized steam-powered model boats, this beautifully crafted boiler combines traditional copper construction, vintage styling and practical safety features in a compact package.
With a 500mL capacity, operating pressure of 2–4 kg/cm² and a butane-powered burner system, the RW-B2 is designed to provide a stable steam supply for compatible model steam engines.
Its elegant copper and hardwood construction also makes it an attractive addition to a model engineering collection, whether used as a functional power system or displayed as a detailed piece of miniature engineering.
The boiler features an integrated curved burner tube, designed to optimize the combustion path and heat transfer within the boiler.
The 500mL capacity provides a practical balance between size and steam output, making the boiler suitable for medium-sized model boats approximately 70–150cm in length, depending on the engine and overall model configuration.
Safety is an important part of the design. The boiler is equipped with several monitoring and protection components, including:
The boiler is designed to operate within a 2–4 kg/cm² working pressure range, with the safety valve providing additional pressure protection.
The boiler is manufactured from copper with copper-silver brazed construction, providing a strong and durable assembly.
A thermal insulation layer and hardwood outer cladding help reduce heat loss while giving the boiler an attractive vintage industrial appearance.
The combination of polished copper, wood and traditional steam-engine styling makes this an excellent choice for model engineers, steam enthusiasts and collectors.
The boiler uses an M7 × 0.75 fitting thread, allowing convenient connection with compatible steam-engine accessories and components.
Its compact dimensions make it easier to integrate into different model boat layouts without taking up excessive space.
