Price upon request
In the winter months I found myself with 80% humidity in the bedroom. After extensive research, I bought a Helty HRV: it really was a gift from the gods! The humidity problem is now under control, and the best thing is that in the morning you breathe clean, fresh air, and at 21 degrees without fail.

The dual flow wall-mounted HRV keeps moisture under constant control and automatically adjusts ventilation to guarantee comfort without wasting energy.
Humidity and condensation under control
With FlowPLUS, indoor air is always fresh, pleasant and purified. Equipped as standard with a humidity sensor, this HRV unit measures the moisture level in the air and automatically adjusts its operation, maintaining optimal indoor climatic conditions and helping to prevent condensation and mould formation. The heat exchanger enables the system to recover up to 91% of the energy from the extracted air, using it to pre-heat or pre-cool the incoming air before supplying it to the rooms.
Comfort and savings, even in summer
With FlowPLUS HRV, indoor temperature remains stable, avoiding on the one hand energy waste and thermal losses caused by opening windows and, on the other, generating savings on energy bills. Thanks to the innovative automatic free-cooling function, the FlowPLUS ventilation system also provides a free contribution to indoor cooling when outdoor temperature conditions are more comfortable. For example, during summer evenings, when outdoor air is cooler and more pleasant than indoor air, the HRV can be used to introduce naturally cool and continuously purified air into indoor spaces, enabling natural cooling at zero cost.
Advanced, quiet, engineered for superior performance
FlowPLUS introduces a significant aesthetic evolution: the new satin-finish plastic cover, characterised by clean, modern lines, further enhances the product, making it even more discreet and easy to integrate into any indoor environment. Compact dimensions and an essential design language recall contemporary lighting fixtures and furnishing elements. For the first time, FlowPLUS is available in two different versions, with either an enthalpy heat exchanger or the new sensible heat exchanger. The enthalpy heat exchanger recovers both heat and moisture, while the sensible version focuses exclusively on thermal recovery, making it ideal for milder climates.
Easy to install, easy to use
Wall-mounted in less than an hour, FlowPLUS can be installed easily and quickly into any residential environment, especially when buildings are occupied or for light retrofits.
In addition to the function panel and infrared remote control, the ventilation system can also be managed via smartphone or tablet through the convenient Helty Home app. The application, developed by Helty, connects units to the Wi-Fi network allowing you to regulate HRV operation and monitor the temperature and relative humidity values in the individual rooms. The only user maintenance is the straightforward replacement of the spent filter when indicated by the unit.
Vertical installation and radon-mitigation version
Compact and modern, FlowPLUS is available in a vertical configuration, an installation that enhances the new geometries and allows optimal condensate drainage management in the version with sensible heat exchanger. For radon gas mitigation, the FlowPLUS-R version is available, enabling the programming of an unbalanced operating mode that prevents radon present in the ground or walls from infiltrating indoor spaces. When combined with the optional Radon Monitor sensor, FlowPLUS-R continuously monitors gas levels and automatically adjusts HRV operation to keep values below threshold.

Frequently asked questions
Helty Flow HRV systems replace and filter the air; they are not air conditioners. Under certain outdoor temperature conditions, the HRV can be used to deliver cooler or warmer air and contribute to the air conditioning of an indoor room.
A wall-mounted HRV can be installed quickly and without costly work. Simply drill two 80mm cores on the perimeter wall, prepare the power supply and fix the unit to the wall using screws and dowels.
