Wall-mounted air heat recovery unit ARHEAT 100mm by No name

The wall-mounted ARHEAT 100mm heat recovery unit by No name is designed for energy-efficient ventilation in residential and small commercial spaces. The unit installs directly into an external wall and integrates with 100 mm duct connections to recover heat from exhaust air and transfer it to incoming fresh air. Its compact design allows for continuous or intermittent ventilation strategies while reducing heat loss and improving indoor air quality.

Advantages

The ARHEAT 100mm unit provides passive heat recovery to lower heating demand without requiring extensive ductwork. Its wall-mounted format saves interior space and simplifies installation compared with large centralized systems. Compatibility with standard 100 mm ducts ensures straightforward connection to existing ventilation outlets or new installations. The unit is suitable for use year-round and contributes to more stable indoor temperatures and reduced energy consumption.

Suitable for

• Individual apartments and single rooms where wall penetration is possible
• Small offices and commercial spaces requiring localized ventilation
• Renovation projects replacing simple extract fans with heat recovery
• Homes aiming to reduce heating costs while maintaining fresh air supply

Key specifications

• Mounting: wall-mounted design for through-wall installation
• Duct connection diameter: 100 mm
• Function: heat recovery from exhaust air to preheat incoming air
• Operation modes: compatible with continuous or intermittent ventilation setups
• Application: suitable for residential and small commercial use

How to use

Install the unit in a suitable external wall opening sized for 100 mm duct connection following building regulations and local codes. Connect the unit to the interior and exterior ducts so that exhaust air flows through the recovery core and fresh air is drawn in the opposite direction. Configure ventilation controls for continuous or intermittent operation as required by occupancy and indoor air quality needs. Regularly inspect and clean filters or cores according to the manufacturer's maintenance guidance to preserve heat recovery performance.

Usage recommendations

For effective performance, place the unit where airflow paths are unobstructed and avoid installing near strong external pollution sources. Combine the heat recovery unit with basic filtration and timed or demand-controlled ventilation to balance energy efficiency and indoor air quality. Schedule periodic checks of seals and ducts to prevent thermal bypass and maintain expected recovery efficiency.
