  • The Italian Job

    Open loop systems abstract groundwater from one or more boreholes. Heat is either extracted or added by the primary refrigerant loop, and the water is returned to a separate well or body of water. The supply and return lines need to be placed far enough apart to ensure thermal recharge of the source. The key issues for open loop systems relate to borehole yields, licensing and, most importantly, ...
