Swedish heat pump manufacturer Qvantum has launched the QG water-to-water heat pump in the UK for apartment projects using 5th generation ambient heat networks and shared boreholes. The company says the unit is designed for new build and retrofit projects in cities where space, noise and air quality can add complexity to heat pump deployment.
The QG is suitable for a mix of energy sources, including ground arrays, surface water, centralised plant and waste heat from nearby assets. It delivers heating, cooling and domestic hot water in a single integrated unit.
The heat pump includes an accumulator tank that acts as a thermal battery with heat storage up to 90°C (194°F). Domestic hot water is produced instantly via a heat exchanger, which the company says eliminates legionella risk and simplifies water quality requirements.
The QG uses R290 refrigerant and is available with an inbuilt source-side pump for individual or shared ground source projects, or with a PIC-valve as the QG-C for ambient loop applications. Both versions are available in 7 kW (approx. 24,000 BTU/h) and 14 kW (approx. 48,000 BTU/h) options.
Key features include a -10°C to 40°C (14°F to 104°F) operating envelope, pre-plumbed plug-and-play design, integrated thermal store, Qvantum app support for remote diagnostics, over-the-air updates and built-in flexible tariff readiness. FlexReady functionality and API connectivity allow the unit to operate during periods of low electricity prices or renewable surplus.
“At Qvantum, we are committed to creating products for the harder to solve projects – for example the challenge of decarbonising urban homes. We believe that you can find real advantages of planning residential energy systems in the context of the wider urban environment. The QG is a solution that allows you take advantage of heat that is being wasted elsewhere to create a system that benefits the homeowner, the property developer and the wider community,” said Philip Ord, UK CEO.
