The hydronic and forced air components of the ground source heat pump system at Bryant Avenue Syracuse, were completed in December 2016, thus completing the urban retrofit geothermal project. The heat pump is a 4-ton combination (water-to-air and water-to-water) unit. The forced air is given priority to bring the house to temperature. The system then switches to water to fill the buffer tank for the radiant system. Three zones of hydronic call for water from the buffer tank to heat the floors.
Given the contribution of the solar PV the first utility bill following installation shows delivery charges only! Note the drastic reduction in natural gas usage from 2016 to 2017!
Stay tuned. An analysis of the return on investment to follow on this blog.
