## Long description

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.
