Lossnay / Home ventilation
Fresh air for your home.
Lossnay brings filtered air in from outdoors and extracts stale indoor air. Its heat-recovery core transfers warmth between the separate air streams. On a cold day, that helps temper the fresh air before it reaches the rooms.
How it works
Fresh air comes from outside.
The intake draws from outdoors, even when the equipment is installed in the roof space. The system extracts stale air while supplying fresh air. A heat pump does a different job: it heats or cools the air in your rooms.
We can assess ventilation on its own or price it alongside a compatible ducted heat pump. We’ll check the duct routes, the outdoor intake and exhaust positions, and access for filter changes.

Manufacturer case study / Christchurch
A vertical unit in the laundry.
At a different home, the roof hatch was too small for the unit. A vertical Lossnay fitted above the laundry freezer and supplied fresh air to three bedrooms and the living area. The position also left the filters within reach.

Wi-Fi control, if you want it.
On a compatible Lossnay system with the right interface, you can adjust ventilation from your phone. We’ll confirm what is included and show you how to use it.
