Solar air heating
The Illustrated Guide to Renewable Technologies BG 1/2008, By Kevin Pennycook, published by BSRIA in March 2008, states: ‘Solar air systems collect solar energy to heat air. The air can be used to pre-heat ventilation air, heat air inside a building, or to heat water. A basic system comprises a solar collector and a hot air distribution system. Solar air systems can also incorporate thermal storage using either the thermal mass of the building or dedicated thermal stores, such as a rock store. The solar collectors can be purpose-built panels or a glazed cavity over an existing façade.’
