This single-room alternate-flow heat recovery unit provides continuous background ventilation while recovering warmth that would otherwise escape. It maintains healthier indoor conditions by managing humidity, supplying filtered outdoor air, and removing stale, moisture-laden air. Its compact, wall-mounted design suits bedrooms, living areas, bathrooms, and retrofit projects where space is limited. Quiet operation and low power consumption ensure year-round performance with minimal running cost.
The unit operates in a timed extract–supply cycle. Warm indoor air is drawn through a ceramic heat exchanger that captures heat before the airflow reverses, allowing incoming air to collect stored warmth. This balanced process maintains comfort while reducing heat loss. An integrated humidity sensor activates increased airflow when moisture rises, supporting mould prevention without user input. Remote control provides simple commissioning, adjustable speed modes, night settings, and the option to lock parameters for compliance in rented homes.
By tackling condensation at its source, the system supports long-term mould reduction and maintains a healthier living environment. Pre-warmed incoming air reduces cold draughts and helps stabilise room temperatures, aiding energy efficiency. Whisper-quiet performance makes it suitable for homes where low noise is essential. Its tamper-resistant configuration helps landlords meet regulatory obligations, while homeowners benefit from reliable, low-maintenance ventilation that protects building fabric and occupant wellbeing.
This solution is suited to single-room ventilation in homes, apartments, and social housing. It is effective in bedrooms, bathrooms, utilities, and other moisture-prone spaces where condensation and mould frequently occur. The compact, duct-free design makes it ideal for retrofit properties, restricted wall spaces, and developments where minimal disruption is required. Landlords, housing providers, and installers can use it to meet internal air quality requirements and support compliance with damp and mould regulations.
The ceramic heat exchanger recovers up to 75% of outgoing heat during alternate-flow operation. Airflow rates accommodate typical single-room applications, and continuous background operation is supported by an energy-efficient EC motor. The unit runs at approximately 16 dB at three metres, suitable for quiet environments and night-time use. Power draw is approximately 2.3 W, enabling 24/7 operation at low running cost. A 140 mm core drill opening is recommended for installation, providing clearance and ensuring the required downward slope for condensation drainage.
