Bonaire MB4 – the 4 star premium choice
The Bonaire M Series MB4 4 star Gas Ducted Central Heater is a first class unit
with enough features to rival those with a 5 star rating.
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 zones
*
for
total heat control. There is also an option to upgrade to an
8 zone system
**
.
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%
***
. 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.
