Water Source Heat Pumps

Recently, we attended a seminar on Water Source Heat Pumps (WSHPs). It seems that the HVAC industry is pushing the installation of WSHPs, in commercial buildings, in order to help reduce green house gas emissions. In effect, WSHPs are taking the place of gas fired furnaces and boilers. Why should the insurance industry be concerned? As shown in the diagrams below, WSHPs use a water loop, much like a chilled water cooling system, to transfer heat to or from the space to be cooled or heated. The amount of piping used in these systems indicates that the volume of water can amount to hundreds of gallons, depending on the size of the building. If a leak occurs, the cost to repair can extend into the hundreds if not thousands of dollars. Similary, the cost to repair or replace property can extend into the hundreds of thousands of dollars. Possible causes of water leakage can include faulty workmanship by the installing contractor and defective materials used during installation.
