Zehnder was extremely helpful with planning and implementing the system also ensuring that it works as intended.”

“The Zehnder system allows us to install a high quality balanced and distributed ERV/HRV solution without the need to install large soffits or chases. ┬áThis systems ducts fit nicely in a 2 x 4 wall, and operate using very low energy, actually exceeding the Passive House requirements for energy use.”

“We chose Zehnder HRVs for the Hollis Montessori Passive House School because of its great combination of high efficiency, low noise, and adaptable controls. The demand controlled ventilation option allows us to automatically vary the ventilation rate based on the occupancy of the classroom”

Jordan Goldman, Engineering Principal, ZeroEnergy Design, Boston, MA

“For TerraHaus we needed an HRV to be as efficient as possible in order to meet the passive house standard for annual heating demand. The Comfoair 550 had the required capacity for this residence hall with 10 occupants, and the Zehnder tubing system made the installation easy without altering framing or building chases.”
