Unico System FAQs
Where can the Unico System be installed?
With its compact, modular design it suits all types of homes — new builds and renovation projects. The flexible ducting fits within the building's fabric and the compact air handler is ideally suited to loft installation.
Why choose Unico over radiators or air conditioning?
It's an all-in-one system, so you can do without radiators and underfloor heating in winter and enjoy conditioned air in summer. It can run on a renewable air source heat pump or complement your existing heating.
How does it improve indoor air quality?
The air handler can run in ventilation-only mode. Alongside standard filtration, UV and high-performance filters can be added to tackle odours and germs, remove airborne bacteria, disinfect the air and help prevent mould through dehumidification.
Is it noisy, and what do the outlets look like?
Sound-deadening insulation on the air handler and flexible supply tubing bring noise down to a soft whisper. The small, discreet room outlets are designed to blend into any décor — and with no radiators, you get more freedom with your interior.
How even is the temperature?
Using the aspiration principle, the Unico System delivers draught-free comfort with less than 2°C difference room to room and floor to ceiling, and removes up to 30% more humidity than conventional systems.
