House solar heating system - has collector in roof where blower circulates air before delivering to rooms

摘要

The system heats a house by means of air heated in a solar collector with a dark body. The collector (34) is mounted in the roof (12), and is connected to a blower (16) causing the air to circulate in the roof before delivering it into the house. Where the house already has an air-heating system, the blower of this system can be used. Where the rafters are thermally insulated, the collector can be mounted in the roof so as to heat them by the air flowing over then under thermosiphonic action.
