Recover up to 95% of your heat that would otherwise be lost using traditional extractor fans.
Enjoy fresh, filtered air all day and night without opening windows, keeping you warmer in the winter and cooler in the summer.
Eliminate condensation and stop black mould before it damages your property — or your health.
Invested in solar or heat pumps? Don’t throw your money away — recover precious heat and energy while ventilating your home.
For landlords: Stay protected against mould claims with compliant, heat-recovery ventilation.
Install it through a single wall in under two hours, with no ducts, minimal mess, and long-term peace of mind.
Breathe cleaner air and keep the heat you’ve paid for.
Whether you're tackling black mould, improving indoor air quality, or simply creating a healthier home, your indoor air needs to be refreshed at least four times every hour.
The problem? Traditional ventilation systems throw all that warm air — and your money — straight out the wall.
Blauberg heat recovery systems capture and reuse that heat while ventilating your home.
"For every £1 of heat and energy typically wasted by extractor fans, Blauberg can recover up to 95p."
By recovering heat instead of losing it, you lower your energy use. It’s a simple, responsible step toward more sustainable ventilation.
Better air quality, less risk of mould, and lower energy bills — all from one smart solution.
With our German heritage, Blauberg is built on precision engineering, reliability, and long-term performance.
The technology in our single-room heat recovery fans is independently recognised by the German DIBt (German Institute for Building Technology) — one of Europe’s most respected authorities in building ventilation.
Blauberg has taken this commitment further, with products like the VENTO-MIDI undergoing independent testing, and achieving DIBt certification to verify airflow performance, energy consumption, and heat recovery efficiency — ensuring the figures we quote are proven for VENTO-MIDI, not theoretical.
For homeowners, specifiers, installers, and social housing providers, that means confidence in a tested, proven solution that supports compliance with Part L , Part F , and the latest requirements under Awaab's Law — all while protecting both properties and people.

Heat recovery fans aren’t just for new builds — they’re often the simplest and most effective choice for existing homes, especially when ducted systems aren’t an option.
They can be installed in any room with an external wall — including bathrooms, kitchens, wet rooms, living spaces, and even bedrooms.
You can use them as standalone units in problem areas or link multiple fans together via Wi-Fi for a coordinated, whole-house solution.
Whether you're solving a specific damp issue or upgrading your entire home’s ventilation, Blauberg offers the flexibility to suit your layout, lifestyle, and budget.
