The new RW-B2 500ml Vertical Steam Boiler is designed to provide stable steam power, elegant craftsmanship, and excellent performance for medium-sized model boats from 70cm to 150cm.

Whether you are upgrading an existing steam-powered boat or building a new project from scratch, the RW-B2 delivers the perfect combination of traditional steam engineering and modern safety design.

A High-Quality Steam Boiler Built for Model Boat Performance

The RW-B2 Vertical Steam Boiler is carefully engineered for model ship enthusiasts who demand both performance and appearance. It features a copper-silver brazing process, providing a strong and durable boiler structure while maintaining excellent heat transfer efficiency.

The boiler body is wrapped with a high-efficiency insulation layer and elegant hardwood cladding, creating a premium vintage appearance while helping improve thermal efficiency during operation.

According to the product specification, the RW-B2 features a 500ml water capacity, a 90mm boiler diameter, and a 140mm boiler height, making it an ideal size for many medium-scale steam boat projects.

Advanced One-Piece Bent Combustion Tube Design

One of the key highlights of the RW-B2 is its integrated curved combustion tube design.

Compared with traditional structures, this one-piece bent combustion tube provides a cleaner internal layout and efficient heat transfer, helping the boiler generate steam steadily for your model steam engine.

The RW-B2 uses butane gas as fuel and operates at a working pressure of 2–4 kg/cm², with a pressure gauge range of 0–6 Bar (kg/cm²), allowing users to monitor steam pressure during operation.

Designed for 70–150cm Steam Boat Models

Finding the right boiler size is essential for a balanced steam boat system.

The RW-B2 is specifically designed for 70cm–150cm model boats, providing enough steam capacity for enjoyable cruising performance without adding excessive weight.

With its 500ml medium-capacity boiler design, it offers an excellent balance between:

It is an ideal upgrade choice for hobbyists who want to transform their model boat into a fully functional steam-powered vessel.

Complete Safety and Monitoring System Included

Safety and control are essential when operating miniature steam systems.

The RW-B2 comes equipped with:

✅ Two pressure relief valves
✅ High-precision pressure gauge
✅ Superheater tube
✅ Water level gauge

These components allow users to monitor pressure, water level, and operating conditions more effectively.

During operation, users can check the water level through the gauge and ensure proper water supply. The instruction manual recommends adding purified water through the filling port and not exceeding the upper limit shown on the water level gauge.

Important Operating Tips for Safe Use

Before operation:

1. Connect the boiler outlet pipe to the steam engine.
2. Connect the butane gas cylinder and make sure the valve is closed.
3. Check that all screws and safety valves are properly secured.

When steam pressure reaches 2–4 kg, open the valve to supply steam to the engine. Always monitor the water level and stop operation when the water reaches the lower limit.

For safety, operate in a well-ventilated area and avoid touching the boiler directly during or shortly after operation, as the system remains hot.
