It is also critical that the heat emitters and pipework are sized to deliver the required heat output at the lower heat pump system flow temperature. The heat pump and additional complimentary heating technologies are then delivered to site ready for installation. Step Two The location for the heat pump should have already been determined, taking into account the clearances required. Anti- vibration feet are put into position on a flat level base - in this case a new patio, and the heat pump is bolted to the feet. T R A I N I N G Step Three A new high-performance cylinder is installed with adequate hot water storage for the household’s needs. This has a larger indirect coil than a standard cylinder to effectively provide hot water with the lower flow temperature from the heat pump. Step Four The heat pump plumbing connections are made between the unit and the cylinder. Step Five Both the electrical supply and controller for the heat pump, along with the system heating controls, are wired and tested by the electrician. Step Six The heat pump pipework is lagged to protect against heat loss. Step Seven A Grant field engineer arrives to assist with system set up and commissioning. They run through the heat pump parameters on the controller with the installer and check the heating system controls are set to achieve the required system performance. Step Eight A comprehensive handover with the homeowner is provided to ensure they fully understand the system and the importance of having it serviced on an annual basis. The job is complete.
