Trianco introduces the Activair R290 indoor heat pump, offering heating and cooling for properties where outdoor units are impractical.
Trianco has introduced the Activair R290 Indoor Heat Pump, a new heating and cooling solution designed specifically for properties where fitting a standard outdoor heat pump unit presents installation challenges. The system provides both space heating and active cooling capabilities while utilising R290 refrigerant, a propane-based gas with a low Global Warming Potential (GWP).
Traditional air-source heat pumps require significant exterior wall space or ground clearance, which can complicate retrofits in flatted developments, listed buildings, or properties with strict local planning constraints. By housing the primary unit indoors, the Activair system offers heating engineers and installers an alternative approach for tight urban sites and multi-occupancy buildings.
What does this mean for a UK tradesperson or DIYer actually buying this kit — does it change what they should pay, buy, or watch out for?
For heating installers and plumbing contractors, this unit opens up heat pump retrofits in properties previously deemed unsuitable for outdoor monobloc or split units due to planning restrictions or space limits. When quoting job costs, installers will need to factor in the specific ducting and ventilation requirements necessary to discharge air internally or through minor wall penetrations, alongside handling R290 refrigerant safely. While exact trade pricing will depend on merchant stockists, positioning an indoor R290 unit as a problem-solving option allows installers to capture heat pump installation work in urban domestic flats without relying on external wall mounting.
Plumbing and heating professionals should ensure proper space planning inside the property to accommodate the unit footprint, alongside reviewing ductwork runs to maintain efficiency. As the UK market continues to shift towards low-carbon heating solutions to meet updated building performance targets, alternative internal formats broaden the options available to heating engineers specifying work for difficult domestic layouts.
