Vento Maxi - For Kitchens & Utility Rooms MVHR Single Room Heat Recovery Unit
BIM Objects
User Guides & Data Sheets
The VENTO MAXI is a wall-mounted single room heat recovery unit designed for kitchens and utility rooms - spaces where cooking, laundry and daily tasks create heat, moisture and odours.
Using a push-pull ventilation process, VENTO MAXI works in cycles: it first extracts warm, stale air, then supplies fresh, filtered air from outside. As the warm air is removed, the unit stores valuable heat inside. When the airflow switches, the heat created is transferred to the fresh air and then supplied back into the room.
This continuous ventilation process keeps kitchens and utility rooms dry, fresh and energy-efficient, helping reduce condensation, clear out lingering smells, lower humidity and cut the risk of mould- all while saving heat and energy.

Why choose VENTO MAXI?
VENTO MAXI delivers all the benefits of traditional kitchen and utility room ventilation without extracting heat or energy.
It works like a centralised heat recover system (MVHR) system but for single rooms, making it an ideal solution for kitchens and utility rooms, where condensation and odour control are essential.
"With VENTO MAXI, you can recycle up to 85% of the energy and heat that is normally lost through standard kitchen extractor fans.
That means for every £1 of heat extracted using kitchen ventilation, you could save up to 85 pence."
By recycling warmth from the air it extracts, VENTO MAXI helps cut energy use, lower heating bills and takes the pressure off your central heating system.
If you’re upgrading to renewables like solar panels or heat pumps, VENTO MAXI is a smart addition, helping you get even more from your energy-saving setup.
The VENTO MAXI operates using a push-pull heat recovery cycle, specially designed to ventilate kitchens and utility rooms.
The unit runs in timed phases, first extracting warm, humid air from the room, then drawing in fresh, filtered air from outside.
During the extraction phase, heat from the outgoing air is absorbed and stored inside the high-efficiency thermal core.
When the fan reverses direction, the stored heat is transferred to the incoming air, allowing fresh air to enter your kitchen or utility room without losing warmth.
This alternating cycle runs continuously, maintaining a balanced airflow while retaining up to 85% of the room’s heat, unlike traditional extractor fans that vent warmth straight outdoors.
The result is a smarter, energy-efficient ventilation method that helps keep moisture, odours, and condensation under control, especially in rooms where steam, cooking and washing machines create a demanding air environment.

How to install a VENTO MAXI.
VENTO MAXI is built for quick, hassle-free installation through an external wall, making it ideal for kitchens and utility rooms—whether in new builds, renovations or retrofits with limited access. Note: VENTO MAXI units are not suitable for in line, or duct installations.
The unit requires a 160mm wall opening, so a 180mm core drill is recommended. This size is widely available online or from builder’s merchants.
It comes in two versions to suit different wall types: a standard model for walls between 300mm–500mm thick, and a compact version for slimmer constructions down to 150mm.
With no ducting required and easy access for maintenance, VENTO MAXI provides a simple, mess-free upgrade to your kitchen or utility room ventilation—improving air quality without disrupting the fabric of the building.
