What would you like to do:
Efficient brine-to-water units sourcing renewable energy from the ground or boreholes to provide heating and cooling services to all building types.
Get in touch
Ground source heat pumps (GSHP) offer a greater all year-round efficiency compared to an air source or water source heat pump alternative. They do require early consideration, however, due to the space needed to bury the ground loop or factor in digging a borehole.
Benefits and Application
The energy efficiency of our units can be seen through their Coefficient of Performance (COP). Our GSHPs have a COP of circa 5.0+ at a water temperature of 35°C. We offer both high temperature and reversible units, with MCS approved and ETL listed ranges.
Our heat pumps are tested to the latest EN standards, including EN15316, EN14511 and EN14825. We use our advanced testing facilities within our German and Irish factories to ensure we are giving you accurate information and products that perform to the standards you require.
Applying single or cascaded GSHPs to your design can be difficult, which is why our specialist engineers are on hand to offer you advice. When specifying our products, we will offer guidance on required buffer vessels and water cylinders, alongside hydraulic schematic advice.
We offer a range of three phase ground source heat pumps for commercial and residential projects:
| Product Range | Description | Nominal Rating at B0/W35* | Controller | Max Flow Temp |
|---|---|---|---|---|
| SITU | Brine-to-water heat pumps | 18 - 22kW | WPM ECONPLUS controller This is a BMS compatible controller via additional plug in cards, able to work with BACnet and ModBus |
58-62°C |
| SITU inc. circulation pumps | Brine-to -water units including a circulation pump | 26-130kW | 62°C | |
| SIH | High temperature brine-to-water heat pump | 20 - 90kW | 70°C | |
| SITUR+ | Reversible brine-to-water heat pump with waste heat recovery | 130kW | 58°C | |
| *B0= brine temperature at 0°C / W35= water temperature 35°C Brine refers to a water anti-freeze mix | ||||
