This training rig enables the principles of Ground Source heat pumps to be demonstrated on a single unit and is an ideal teaching tool. It allows students to familiarise themselves with the connections of a heat pump and its components. Trainees can also physically feel the heat generated by the heat pump and understand how it absorbs heat from the ground via the ground array. The training rig features a high temperature single compression heat pump positioned above a ground array (Approx. 25M x 32mm MDPE flexible pipe) and 3-Portheating manifolds linked to short sections of heating pipe.
