Active Solar Heating is a low energy heating method that relies on the heat of the sun's rays to warm air in a large panel oriented to the sun. The active component involves a series of small computer fans that pump the air down chimneys into a room for directly heating the air, or as in our case into a large solar battery below the floor. The computer fans require only a very small solar panel to operate. For the pit we dug out 3.5 ft of the floor inside the room, reinforced the walls with stone masonry, applied insulating lime and perlite plasters, and filled the cavity with large rocks leaving space between to allow the air to easily move between allowing the rocks to absorb the heat. The cooler air is then recycled through another chimney bak up to the roof panel to be heated again. The next stage is to install either an earthen or lime floor above it. The system will operate when the sun is out and the rocks will radiate heat up through the floor 24hrs a day. It is anticipated this room will remain a comfortable 12 to 14 degrees celsius even when outside temperatures dip to minus 30. Previously this system had been installed at other properties using cement and steel and thermocouples insulation. Ours is the first all natural system. We had a talented team from Ladakh help us with the installation.
