Is Bonaire a Good Choice for Melbourne Homes?
Yes. Bonaire ducted heating Melbourne outer suburbs install pays off most in growth corridor homes, where cold nights and mild shoulder days turn the MB4's wide modulation range into real savings.
The Bonaire MB4 pairs a modulating gas valve with a variable speed fan, letting it run anywhere from full output to as low as 10% of its total capacity. Conventional staged heaters jump between fixed steps, so on a 16°C April afternoon they overshoot, shut off and restart. The MB4 simply idles low, keeping rooms steady and trimming gas use across the long outer-suburban heating season.
King & Sons installs every current Bonaire heater Melbourne homes can choose from: the MB4 (14kW to 35kW, 4-star), the MB5 (15kW to 35kW, 5-star) and the Rhino (21kW or 30kW, 5-star downflow external unit). The MB4 and MB5 include integrated 4-zone control as standard through the Bonaire Navigator controller, which Melbourne homeowners can mount on the wall or use as an RF remote.
