Heat recovery units with a diameter of 100 mm for local ventilation of smaller spaces

The category heat recovery units with a diameter of 100 mm includes compact local devices intended for ventilating smaller spaces such as bathrooms, toilets, smaller rooms, and hallways. The 100 mm heat recovery unit is an ideal choice when you need efficient supply-exhaust ventilation with heat recovery but lack space for a larger unit. Despite the small diameter of the duct, it ensures a stable airflow, reduces humidity, and prevents mold formation.

In our offering, you can find various models, from simple units for basic local ventilation to advanced solutions with multiple speed settings, quiet operation, and advanced control options. This way, you can choose a 100 mm heat recovery unit that optimally adapts to your space and usage – with minimal construction interventions and low energy consumption.

Mini and local heat recovery units with a diameter of 100 mm for bathrooms and smaller spaces

Mini heat recovery units or local systems with a diameter of 100 mm are particularly suitable for spaces where humidity is present and rapid temperature changes occur – most commonly for a heat recovery unit for bathrooms or separate toilets. By installing such a system, you ensure a constant supply of fresh air from outside while simultaneously removing used air, transferring most of the heat back into the room.

This category also includes specialized models, such as aRheat and selected heat recovery units with a diameter of 100 mm, which combine a high level of efficiency, quiet operation, and easy installation. These mini heat recovery units are an excellent solution for bathroom renovations or smaller apartments where there is no option for central systems.

Ducted heat recovery unit with a diameter of 100 mm – discreet installation in the wall or duct

Ducted heat recovery unit with a diameter of 100 mm is designed mainly for installation in an exterior wall or a short section of a round air duct. Due to its 100 mm diameter, the structural penetration is minimal, facilitating installation in both new constructions and renovations. At the same time, this solution typically does not require a complex duct system, as the device works directly through the wall – meaning less construction work and faster installation.

Advanced features: WiFi, filtration, and easy management

More modern heat recovery units with a diameter of 100 mm can be equipped with additional features, such as WiFi heat recovery units, allowing control via a mobile app or smart home. This way, you can adjust the airflow and operating modes to your schedule and reduce energy consumption when the space is not in use.

Special attention is also given to filtration. Selected models have built-in filter cartridges that remove dust and larger particles from the air, contributing to better indoor air quality. Filters can be easily replaced, ensuring long-term hygienic operation of the device. For demanding buildings, we recommend combining the 100 mm heat recovery unit with more advanced air recovery systems in other rooms for a unified ventilation concept for the entire apartment or house.

When to choose a 100 mm heat recovery unit instead of a larger diameter?

100 mm heat recovery unit is the optimal choice when:

• it is a smaller space (bathroom, toilet, smaller room),
• you want minimal wall penetration and a discreet external finish,
• there is no space or need for a larger local or central system,
• you need a quick and cost-effective solution for local humidity and odor issues.

For larger living spaces or if you want to connect multiple rooms into a unified system, it may make sense to also consider stronger models or a combination with other categories of heat recovery units. For assistance in choosing, you can contact our support, which helps you find the appropriate local system based on the size of the spaces and the intended use.
