Bonaire 18.5kW external gas ducted heater (MB320E)

The Bonaire MB320E is an external gas ducted heater rated at 18.5kW, from the Bonaire MB series with a 3 star rating. The cabinet is an outdoor mounted unit.

  • Capacity: 18.5kW
  • Model: MB320E
  • Star rating: 3 stars
  • Installation: external, outdoor mounted cabinet
  • Configuration: ducted heating

Placed outside against the house, the heater sends warm air through supply ducts into the building and out through outlets in each room. Air from the rooms comes back to the cabinet through a central grille and duct to be heated again. Keeping the cabinet outdoors means the roof space does not have to hold the heater or an internal flue, though the ducts still run through the roof or under the floor. Installation, gas connection and flueing must be carried out by a licensed gasfitter.

If this heater is replacing an older external unit, compare the duct connections and base position with the existing one. Check the outdoor position keeps the clearances required from windows, doors and boundaries, confirm the property's gas type against the heater ordered because the listing does not state it, and have an 18.5kW output confirmed by a heat load assessment.

Manufacturer's warranty terms vary by brand, and some manufacturers require installation by a licensed technician or purchase from a dealer they have authorised, so please ask us for the manufacturer's published warranty terms before you buy; your rights under the Australian Consumer Law are not affected.

Refrigerant-based systems must be installed by an ARC-licensed technician, gas appliances by a licensed gasfitter, and electrical work by a licensed electrician. Manufacturers may refuse warranty claims where installation does not meet these requirements.

If you have a problem, contact us with your order number and a description of the fault, and we will help you with the claim.
