Specifications                   component. Most commonly seen
                                 in the form of indirect water tanks.

                                 supplemental because it is very
                                 difficult to heat 100% of a building.
                                 This is because our annual solar
                                 radiation pattern does not meet our
                                 heating load pattern.
