By eliminating the need for outdoor units, delivering high-temperature operation, incorporating low-GWP refrigerants and providing advanced remote monitoring capabilities, the Activair range demonstrates how modern heat pump technology has evolved. For specifiers seeking practical, scalable and future-proof heating solutions, it offers compelling evidence that the next phase of heat pump adoption will be driven not by policy alone, but by products designed to solve real-world challenges.
More than a decade after the introduction of renewable heating incentives, air source heat pumps continue to attract mixed opinions across the building services sector. While concerns over cost, performance and suitability for existing housing stock persist, advances in technology are helping to address many of the barriers that have slowed adoption.
One manufacturer leading this evolution is Trianco; the Activair range has been developed not only to improve efficiency, but also to overcome the practical challenges that specifiers, installers and homeowners face when transitioning to low-carbon heating.
A longstanding obstacle for heat pump deployment has been the requirement for an outdoor unit, limiting the product’s suitability for apartments, conservation areas and properties with restricted external space. Activair R290 Indoor Heat Pump directly addresses this issue by locating the heat pump within the building and using ducted air connections through an external wall. Available in 3.2kW wall-mounted and 5kW floor-standing models, the system eliminates the need for an external unit while providing an effective renewable heating solution for applications previously considered unsuitable for heat pumps.
Alongside the indoor model, the wider Activair High Temperature range has been designed for both retrofit and new-build projects. Available in outputs from 5kW to 22kW, the units utilise inverter-driven technology to optimise performance and reduce energy consumption. The use of R290 refrigerant, one of the lowest GWP refrigerants available, supports sustainability objectives while enabling flow temperatures of up to 75°C. This can help reduce the need for immersion boosting and, in some refurbishment projects, may allow existing radiators to be retained, simplifying installation and reducing costs.
As with any heating technology, successful heat pump performance depends on good design, correct sizing and quality installation. Encouragingly, industry standards continue to improve through initiatives such as MCS certification and ongoing installer training, helping to ensure systems deliver their intended efficiency and comfort levels.
Another important development is connectivity. Activair heat pumps feature smart app controls and integrated SIM technology, allowing remote commissioning, performance monitoring and diagnostics. For housing associations, local authorities and other large-scale housing providers, this provides valuable operational insight while helping to reduce maintenance costs and improve resident support.
With enhanced government grants improving affordability and manufacturers developing solutions that address real-world installation challenges, the conversation around heat pumps is beginning to change. The issue is no longer whether heat pumps can contribute to decarbonisation, but how quickly they can be deployed across the UK’s diverse housing stock.
By eliminating the need for outdoor units, delivering high-temperature operation, incorporating low-GWP refrigerants and providing advanced remote monitoring capabilities, the Activair range demonstrates how modern heat pump technology has evolved. For specifiers seeking practical, scalable and future-proof heating solutions, it offers compelling evidence that the next phase of heat pump adoption will be driven not by policy alone, but by products designed to solve real-world challenges.
