Hybrox

Air source heat pumps deliver outstanding energy efficiency, significantly reducing heating costs compared to traditional gas boilers or electric heating systems. The Modutherm range achieves COPs up to 5.55 and A+++ energy efficiency ratings, meaning they produce over five times more heat energy than the electricity they consume. The Hybrox series (10-18kW) achieves COP up to 5.55 at A7/W35 conditions, whilst the AW290 range (35-100kW) delivers COP up to 4.4. This exceptional efficiency translates directly to lower energy bills and reduced carbon emissions. Air source heat pumps extract renewable heat from outdoor air, even at temperatures as low as -22°C, making them reliable year-round heating solutions for UK climates. With natural R290 refrigerant that has a Global Warming Potential of just 3 and zero Ozone Depletion Potential, these systems offer both economic and environmental benefits that align with net-zero carbon targets and increasingly stringent building regulations.

Air source heat pumps provide both heating and cooling from a single system, offering year-round climate control and exceptional value for money. The AW290 range delivers 35-100kW heating capacity and 8.6-85kW cooling capacity, making it ideal for commercial applications including offices, hotels, schools, and leisure facilities. This dual functionality eliminates the need for separate heating and cooling systems, reducing capital costs, installation complexity, and ongoing maintenance requirements. The systems can provide space heating via radiators or underfloor heating, domestic hot water production, and air conditioning during summer months. With flow temperatures up to 78°C at -22°C outdoor temperatures (Hybrox), these heat pumps work effectively with existing radiator systems in retrofit applications, whilst also being optimised for low-temperature systems in new builds. The ability to cascade multiple units allows heating capacities up to 1,600kW, making air source heat pumps suitable for large-scale commercial developments.

Air source heat pumps are at the forefront of the UK's transition away from fossil fuels, fully aligned with the Future Homes Standard and net-zero carbon commitments. Unlike gas boilers that burn fossil fuels, air source heat pumps extract renewable heat from the outdoor air and use electricity to transfer that heat into buildings. When powered by renewable electricity from solar panels or green tariffs, they offer a truly zero-carbon heating solution. The Modutherm range uses natural R290 refrigerant with a Global Warming Potential (GWP) of just 3, compared to thousands for synthetic refrigerants or the carbon emissions from gas combustion. This makes them one of the most environmentally responsible heating technologies available. With no combustion & no flue requirements, air source heat pumps eliminate carbon monoxide risks and reduce maintenance demands. As grid electricity continues to decarbonise, the environmental performance of heat pumps improves automatically, providing long-term sustainability without equipment replacement.

Air source heat pumps offer flexible, scalable solutions suitable for single dwellings through to large commercial developments. The Hybrox range (10-18kW) is ideal for individual apartments, houses, and small commercial properties, whilst the AW290 series (35-100kW, expanding to 100kW in Q3 2026) serves larger applications. Multiple units can be cascaded together to achieve heating capacities up to 1,600kW, making them suitable for hotels, apartment blocks, schools, leisure centres, and industrial facilities. This scalability provides design flexibility and allows systems to be sized precisely to match building loads, avoiding the inefficiencies of oversized equipment. Air source heat pumps can be installed as standalone systems or integrated into heat networks, combined with buffer vessels for hydraulic separation, or paired with thermal stores for domestic hot water production. The compact outdoor units equire minimal space making them suitable for properties with limited plant room space or restricted external areas.

Modutherm's air source heat pumps feature advanced controls and connectivity options that maximise efficiency, comfort, and ease of management. Smart controls optimise operation based on outdoor temperatures, occupancy patterns, and electricity tariffs, reducing running costs whilst maintaining precise indoor comfort levels. The systems integrate seamlessly with building management systems (BMS) via Modbus connectivity, enabling remote monitoring, performance analytics, and fault diagnostics. This connectivity is particularly valuable for commercial properties, housing associations, and multi-dwelling buildings where centralised management reduces operational overhead. Weather compensation adjusts output automatically based on outdoor conditions, eliminating temperature overshoots and improving comfort whilst reducing energy waste. The Modutherm range is compatible with smart home systems, time-of-use electricity tariffs, and demand-side response programmes, allowing operation to be scheduled when grid electricity is cheapest or greenest. When paired with solar PV systems, air source heat pumps can be configured to operate primarily when renewable electricity is being generated, further reducing energy costs and carbon emissions.
