Full Description

The maintenance requirements of a well designed and constructed solar air-heating system are comparable to those of conventional, forced warm air heating systems. One of the major reasons for this low maintenance is the absence of problems associated with corrosion, freezing, boiling, and leakage often encountered in solar liquid systems.

Experience shows that most problems are due to overly complex designs, control problems, faulty installation, and adjustment of the moving parts in the system. Operational histories show negligible requirements for maintenance of air collectors, pebble-bed heat-storage bins, and system ducts and connections.

Good quality control in the manufacture and installation of airtight collectors, heat-storage bins, and interconnecting ductwork is essential, however.

The paper includes a description of solar air-heating systems and their characteristics, an evaluation of the various maintenance requirements, and several case histories illustrating the handling of solar air system maintenance.
