    1 USER INSTRUCTIONS 1.1 Intended Use The Warmflow Ground source heat-pump units are intended for the production of hot water for space heating and sanitary water. The units can be used to provide heating and domestic hot water (DHW) via underfloor heating circuits, radiators and approved hot water cylinders. The units are designed to extract heat from the ground using a horizontal ground collector or a vertical borehole collector.

  • Page 6: Product Data

    Heat is extracted from the ground by pumping brine around a horizontal surface collector or vertical borehole collector. Brine is a mixture of water and anti-freeze (mono ethylene glycol), to allow operation in sub-zero temperatures. This collected heat is then transferred into the heat pump’s refrigerant via a heat exchanger known as the evaporator.

  • Page 43: Incoming Supply

    3.6.1 Incoming Supply Both the GS08 and GS16 units require a single phase 230V 50Hz electricity supply. The GS08 is rated at 30Amps whilst the GS16 is rated at 40Amps. As these units are variable speed, during starting the compressor speed is ramped up slowly meaning there is not a high starting current commonly associated with fixed speed units and as such there is no need for a very large power supply or the use of starting capacitors.

    The heating pump should then be turned to ‘ON’ and the speed set to 25%. The flow rate for the heating circuit can then be found in the in/out sub-menu of the engineer menu as shown in Figure 82 above. This value should be recorded in the commissioning certificate. The heating pump should then be set to 100% and the flow rate value again recorded in the commissioning certificate.
