Lossnay HRV Systems

Lossnay Heat Recovery Ventilation from Mitsubishi Electric is revolutionising indoor air quality. While most ventilation systems are no better than opening a window letting valuable heat escape, Lossnay brings fresh filtered air in and recovers heat energy from the outgoing stale air which is then used to pre-warm the incoming fresh air. The end result is a healthier, drier and warmer home whilst maximising energy efficiencies.

Combat Condensation & Prevent Overheating
