This document is the repository of Beacon’s core facts and knowledge about unflued gas heaters drawn from a range of publications and research.
Unflued gas heaters burn gas to produce heat but they have no flue or chimney to transfer combustion products outside. These combustion products include: water, nitrogen dioxide, sulphur dioxide, carbon dioxide, carbon monoxide, benzene, butadiene, fine particulates and
formaldehyde. These significantly reduce the indoor environment quality of New Zealand homes, harming occupants and reducing the durability of the building.
