Stiebel Eltron Stratos power-flued gas room heater

The Stratos from Stiebel Eltron Australia is an energy-efficient, power-flued gas room heater, designed for Class 1 buildings such as freestanding houses and townhouses. Power-flued heaters are sealed units where air for combustion is drawn from outside. The heater must be installed on the inside of an exterior wall to allow the flue to be passed directly through the wall.

The heaters are designed to provide consistent warmth through efficient uniform heating emitted from the base of the system. This is said to minimise stratification of the air and improve overall heating. An in-built humidifier tray can increase comfort levels for those more sensitive to air quality. There are four sizes available in the range with up to a 4.6-star energy efficiency rating.

The combustion chamber of the unit is separated from the air that heats a room and the exhaust gas is blown through the flue to the outside of the building. Isolating the two air flows means there are no harmful fumes inside. The heaters achieve a 6-star indoor emissions rating as per AS4553 confirming zero indoor emissions.

The design is versatile, with the flexibility of wall or floor mounting and an optional, programmable, wireless climate controller. The wireless climate controller can control up to three heaters and can be positioned up to 10 m from the heater. The climate controller has a temperature sensor that overrides the manual thermostat on the heater, so the positioning of the climate controller in colder parts of the room assists in providing greater heating comfort.
