Quick Answer
Choose a location for a thermal mass bench that receives direct sunlight and is close to the heat source, ideally within 10-15 feet of a rocket mass heater.
Site Selection Criteria
When selecting a location for a thermal mass bench, consider the site’s aspect and orientation. Ideally, the bench should face south in the northern hemisphere to maximize direct sunlight exposure. A slight deviation of 15-20 degrees east or west can also work, depending on the site’s specific conditions. Ensure the location is clear of obstructions, such as trees or buildings, to allow for unobstructed solar radiation.
Distance and Heat Transfer
Position the thermal mass bench within 10-15 feet of the rocket mass heater to optimize heat transfer. This proximity allows for efficient heat transfer through radiation and convection. As a general rule, the bench should be positioned at a 90-degree angle to the heater’s flue pipe to maximize radiant heat transfer.
Bench Placement and Integration
When placing the thermal mass bench, consider integrating it with the surrounding architecture. A well-designed bench can serve as a functional space for cooking, seating, or even as a night-time heat sink. Ensure the bench is level and securely anchored to the ground or foundation to prevent settling or movement over time.
