Unlike traditional positive pressure ventilation systems, Lossnay is a balanced pressure solution that pre-warms (or cools) incoming air which can help save on your power bill. It does this by recovered heat energy from the outgoing stale damp air. The end result is a healthier, drier and warmer/cooler home.
There are two types of Ventilation systems available in New Zealand:
Air goes in and gets trapped.
These systems typically force air into the home from the attic space and specifically require gaps in the building structure (common in older homes) to facilitate air displacement. As these systems are not designed to recover heat energy to help pre-warm incoming air, colder incoming air will require more additional heating – adding to your power bill.
Air goes in and comes out.
Balanced ventilation mechanically removes stale air and replaces it with clean, fresh air at the same rate. It is also fitted with a heat exchanger that actively recovers heat energy from the outgoing stale indoor air to pre-warm incoming fresh air. As such, the need for additional heating of fresh air is reduced. This system is specifically designed for modern homes that are of more airtight construction.
