Quick Answer
A Rocket Mass Heater (RMH) does not necessarily require a permanent installation, as it can be designed and built to be mobile and easily relocated.
Design Flexibility
A well-designed RMH can be built using a variety of materials, such as steel, ceramic, or refractory concrete, which can be transported and set up in a new location. The core components, including the heat riser and flue, can be disassembled and reassembled as needed. This makes it ideal for seasonal or temporary use.
Portability and Relocation
To make an RMH more portable, it’s essential to use lightweight materials and a compact design. For example, a small RMH can be built using a 6-inch diameter heat riser, which can be easily transported and set up in a new location. When relocating an RMH, it’s crucial to ensure that the new site has proper ventilation, as the flue gases can be hazardous if not properly dispersed.
Considerations for Permanent Installations
While an RMH can be designed for portability, it’s often more practical to build a permanent installation, especially in areas with harsh weather conditions. A permanent RMH can be designed to withstand extreme temperatures, wind, and snow loads. This can be achieved by using more robust materials, such as steel or concrete, and by incorporating features like windbreaks and snow shields.
