Description: A heat exchanger system using hot water supplied by a biomass boiler burning wood logs was installed in combination with a passive solar hay batch dryer. The dryer could hold up to 7620 small 22.5-kg bales stacked over 8 rows. Bales were dried down to 12 % moisture content (m.c.) in 20 days. The dryer consisted of four 3.70-kW centrifugal fans mounted with 64-kW heat exchangers that heated a fraction of the total solar pre-heated airflow. The 146-kW boiler could supply 2 heat exchangers for an 8-hour period with a single wood load of 150 kg. The average gain of air temperature was 8.8
