Bivalent Systems
The following designs show the impact of a single 40kW heat pump on various numbers of properties.
Each property is 2 bedroom 3 person, and 4kW heating load.
Topping up boilers are included to achieve peak loads.
| Properties | % Heat Pump | Design Link |

This graph shows how the vast majority of load (for 2021) is driven by heat pumps (blue & orange), with boilers (green) used to top up.
Heat Pump Selection
Specifically designed for commercial sanitary hot water application, where gas boilers, combined heat and power systems (CHP) or electric water heating have been traditionally utilised, the QAHV provides a low carbon solution for hospitals, hotels, leisure centres and student accommodation. Utilising the natural and stable refrigerant CO2 (R744), the environmentally clean solution enables compliance to strict local planning laws and boosts BREEAM points. Compounded by the increasing decarbonisation of the electrical grid and the UK’s commitment to Net Zero 2050, the QAHV provides a high efficiency, low carbon hot water delivery solution with leaving water temperature up to 90°C.
