This 9 September 2026 review examines a compact MVHR announcement through selection criteria. It is neither a brand ranking nor universal product approval.
Event and source
Zehnder UK announced EVO for constrained installation spaces on 21 April 2026. This is a manufacturer release; verify certification and performance claims for the exact model.
Compactness is not installation readiness
Small dimensions do not eliminate space for ducts, attenuators, drainage and filter replacement. The project needs the full installation volume, not merely the casing.
Comparable data
Request flow at required pressure, electrical input, heat recovery, sound and leakage. Compare matching test conditions rather than maxima from different promotional pages.
Modes and maintenance
Check frost protection, bypass, condensate and any moisture recovery. Verify local service, consumables and documentation availability separately.
What is not established
ZeroHouse has not tested this product and makes no superiority finding. The next review target is 9 October 2026; selection needs the datasheet and relevant certificate where claimed.

What this means for your project
Use the announcement to reconsider installation options. Base final selection on duct calculations and verified model data.
