Helty Flow Plus w/ Hygrometric Sensor - Retro Fit Dual Flow Decentralised Wall-Mounted HRV

The Helty Flow Plus is a premium wall-mounted, decentralised heat recovery ventilation (HRV) system designed for energy-efficient, humidity-regulated air exchange. Built with an integrated hygrometric sensor, it continuously monitors indoor moisture levels and adjusts ventilation performance automatically-ideal for keeping condensation and mould at bay in bedrooms, bathrooms, apartments, and home offices.

With a TUV-certified 91% heat recovery rate, the unit captures and reuses warmth from outgoing stale air to pre-condition incoming fresh air, cutting energy waste significantly. The manual electronic bypass (free cooling function) allows users to enjoy naturally cool air during mild summer evenings, contributing to thermal comfort without running the air conditioner.

Extremely quiet with a sound pressure level starting at just 18 dB(A), the Flow Plus operates discreetlyeven at night. Installation is simple, requiring only two 80 mm wall cores and a standard 230V power connection, making it a perfect solution for occupied homes, retrofits, and DIY upgrades.;
