ComfoAir Q, the new range of MVHR units from Zehnder, has been awarded Passivhaus certification for its “outstanding” heat recovery benefits. The range provides up to 96 percent heat recovery, making it the most energy-efficient unit available today.

MVHR (mechanical heat recovery and ventilation) units are whole house systems which have been developed to achieve a comfortable, energy efficient and healthy indoor environment in line with the latest Building Regulations for modern homes.

In addition to offering world-leading heat recovery benefits, the ComfoAir MVHR range protects homes from excessive humidity and ensures a healthy, dust-free environment. The units are almost silent during operation, running at 42dB(A).

Available in three sizes (350, 450 and 600m³/h), the units benefit from a simple installation process and are convenient to commission. A simple, integrated commissioning wizard and app assists with setting up the system exactly as required, and the process concludes with an automatic system test and confirmation.

The units can be operated through a smart phone app and can be easily monitored through removed access on the Zehnder web portal.  

By attaining the Passivhaus standard, ComfoAir Q units can be specified by architects to minimise a building’s ‘heating demand’ and achieve a sustainable and energy efficient environment.
