Bonaire MB4

Ducted Gas Heater


The Bonaire M Series MB4 4 star Gas Ducted Central Heating System is a first class unit with enough features to rival those with a 5 star rating (NZ energy star rating).

The MB4 achieves its four star efficiency with its multi tube heat exchanger combined with a modulating gas valve which minimises gas usage.

The secret to the MB4’s outstanding energy efficiency is its unique multi-tube heat exchanger, with its modulating gas valve and modulating room air fan, that minimises gas usage and maximises the heat transfer to your home.

The MB4 also offers you the choice of the Navigator Remote Controller, or the Navigator Wall Mounted Controller, which are both fully programmable with 4 integrated zones2 for total heat control. There is also an option to upgrade to an 8 zone system3.

The Bonaire MB4, using the advanced technology of unique modulation, is able to match the load requirements of your home by reducing its heating capacity to 10%4. This reduces gas consumption, giving you reduced energy bills while providing the ultimate in comfort.

Of course, the MB4 comes with the peace of mind of a 5 year domestic parts and labour warranty and 10 year parts only warranty on the heat exchanger and burner1.

The Bonaire MB4 4 star has all the benefits of the 3 star plus more.
