Brivis StarPro 21kW EXT gas ducted 5 star (SP521ENV4)
The Brivis StarPro SP521ENV4 is a 21kW gas ducted heater with a 5 star gas energy rating, configured for external installation.
- Capacity: 21kW
- Model: SP521ENV4
- Series: StarPro
- Gas energy star rating: 5 stars
- Installation: external
The heater is fixed outside the building, and heated air is distributed through ducting to ceiling or floor outlets inside. Room air is drawn back to the cabinet through a central grille and duct to be heated again. Because the cabinet is external, there is no heater or flue in the roof space, only the ducts that run from the heater to each outlet. When replacing an older external heater, the existing duct connections and base can often guide the position, though the installer must confirm the new cabinet's clearances. Installation and gas connection must be carried out by a licensed gasfitter.
An X/A variant of this heater is listed separately, so confirm the SP521ENV4 is the model your installer has specified. Check the gas type at the property against the heater, as it is not given here, and make sure the outdoor position allows the required clearances around the flue outlet and access for servicing.
