Wonders Pty Ltd recommends, sells and installs only Brivis Gas Central Heating Systems. Brivis have a solid history of producing reliable units and have been the market leader in this industry for a number of years. During our history we have installed most brands and have found Brivis to be the most reliable. Brivis have a range which will cover all applications for both domestic and some commercial use. You can choose from a traditional 3 star rated unit which are fixed in their heat and air output; or a 4 or 5 star rated unit which have greater energy efficiency and are more compact in size. If you require a system where you want to shut some of the outlets off or incorporate a zone into it, then you will require a 4 or 5 star rated unit as these units have the ability to reduce their output accordingly.
Zones are created by installing shutters in the main duct to a specific area. There are rules with the minimum number of outlets open but generally speaking only larger homes benefit by installing zones. The switching of these is done by the wall control and can be installed for both running cost savings or lifestyle convenience, such as being able to not heat bedrooms at the same time as the living areas or vice versa.

We only use silver sleeve fire rated ducting which is carefully sourced from 2 suppliers. There are a few differences in duct types and generally the industry will use either a wire cored duct with either a silver foil or plastic outer sleeve over the insulation. Silver sleeve is more expensive and longer lasting than plastic which perishes more quickly. In amongst the main different suppliers there are various different qualities of both types. You can be sure when we install your system you will have good quality duct and fittings. From an installation point of view it is always easier to work with higher quality materials so it benefits everybody We can handle and do all sorts of jobs, from new installations, changeover heating units, adding or changing ducts and outlets, upgrades, improvements and designing systems We also have the experience to handle older upflow, downflow and crossflow systems which are found in older homes.
