|Brief Project Description||
This solar space heating project uses a large storage mass below the slab. Pex tubing was installed in a 6" flowable fill slab which sits below a 6" concrete slab with another set of tubes (for backup if used). Any time solar energy is available, it is actively gathered and sent into the storage mass for passive discharge.
This allows for high collector efficiency because of the low temperature operation and the lack of heat exchangers.
In the harsh Northern Vermont climate, 500 gallons of propane was used between October 2009 and May 2010 for a 12,000 sq. ft. building.
