Geothermal Installation – Holliston, MA

TJ’s most recent project involved replacing two 3-ton air-source heat pumps with two Florida Heat Pumps.   The ground loop heat exchanger is two 510-foot vertical bore, closed loop wells.   Every effort was taken not to damage the home’s beautiful landscaping.  TJ’s used a Wilo Stratos ECM-motor circulator with Bulimo zone valves to optimize the efficiency of this geothermal system.  The Wilo Stratos circulator pumps the loop field and two three-ton Bosch heat pumps.  The Bulimo full port valve allows for proper flow through the heat pump. Additionally, TJ’s used braided flexible connections to keep vibration to a minimum and Caleffi flow meters to ensure adequate flow through the unit.  All of our piping is secured to the structure using Raywall struts with vibration isolation.
