HEATING

What are the options?

Gas Ducted
Fixed gas heater which uses natural or LPG gas to heat the air which is then distributed through ducts into your home.


Ducted Reverse Cycle
Ducted reverse cycle air conditioners and heaters consist of a compressor, fan and heat exchange coil and use a refrigerant to cool or heat the air.

How does it work?
Gas Ducted Ducted gas heating consists of a furnace, ducting outlet registers and a return air grille.  The furnace is fuelled by Natural gas or LPG Air is drawn in by a fan and passed over a heat exchanger which warms the air.  Ducts distribute the warm air through the home. The return air grille recirculates air to the furnace beginning the cycle again. Ducted gas heaters can be installed inside the roof space, on an external wall or under the house (the most suitable installation type depends on your house construction).

Ducted Reverse Cycle Ducted Reverse Cycle Refrigerated Air Conditioners have two separate mechanical parts, an outdoor compressor and an indoor unit with fan and heat exchange coil. The outdoor compressor unit compresses liquid into a gas state to allow the refrigeration effect to take place, exactly the same way as does your home refrigerator. When in heating mode the cooling cycle is simply reversed. The compressed gas is transferred into the indoor unit. The fan is connected and then controlled by a room installed thermostat that draws the air from inside the home, passes it through a filter and then recirculates throughout your home approximately 10 times each hour.
How much will it cost?

Gas Ducted Heating
Supply and Installation – $2,000 to $7,000
* Prices are a guide only and could vary depending on a number of factors including size, brand and difficulty of installation. An in house quote is recommended for an accurate price.

Running Cost – Running costs will vary in every home based on a number of factors including the size of the home, the efficiency of the unit installed, and the quality of materials used. Gas heaters will generally provide heating at a lower cost for heating a whole home than refrigerated options.


Ducted Reverse Cycle
Supply and Installation – $5,000 to $25,000
* Prices are a guide only and could vary depending on a number of factors including size, brand and difficulty of installation. An in house quote is recommended for an accurate price.

Running Cost – Electric heat generally is more expensive to run than gas ducted heating. The sizing and zoning of your system is critical to reduce running costs. At Sustainable Air, we specialize in developing energy efficient solutions, and designing systems that will work effectively regardless of the conditions outside.

What is the most effective system?

Gas Ducted
Ducted Gas Heating works efficiently no matter how cold it is outside, so is suitable for all climates. It will cope with all extremes of climate.


Ducted Reverse Cycle
Split ducted systems are suitable for most climates. The colder the climate, the less effective this form of heating will be. This makes sizing the unit you purchase critical. If your ducted refrigerated system is undersized, it will never effectively heat your home.

Considerations?

Gas Ducted
Gas ducted heating can remove moisture from the air and create a drying effect. Optional humidifiers are available on some units, which can reduce this effect and also reduce running costs.
Quality filters and regular cleaning of filters are recommended to reduce dust circulating within your home.
An environmentally friendly option, gas heaters have lower greenhouse emissions compared to electric heaters and inefficient solid fuel heaters. Correct sizing and zoning of your system will minimize wastage and impact on the environment.


Ducted Reverse Cycle
Electric heating can remove moisture from the air and dry the skin and eyes. Optional humidifiers are available on some units which can reduce this effect and also reduce running costs.
Electric heaters have higher greenhouse emissions compared to gas heaters. Correct sizing and zoning of your system will minimize wastage and impact on the environment.
Sustainable air recommends smart zoning option for ducted refrigerated systems.

COOLING

What are the options?

Ducted Evaporative
Evaporative cooling is an entirely natural method of cooling, using only air and water – to cool air through the simple principle of evaporation of water.


Ducted Reverse Cycle Refrigerated
Ducted Refrigerated air conditioners consist of a compressor, fan and heat exchange coil and use a refrigerant to cool or heat the air.

How does it work?
Ducted Evaporative Hot air is drawn into the cooler and passes through water-moistened pads or specifically designed cells. Some of the water evaporates, absorbing the heat as it does so, and cools the air.  This cooled air is then blown into home which forces hot air out through open windows and doors. Ducted evaporative air conditioning units are positioned on the roof with ducting throughout the roof space to direct air into the rooms of the home.


Ducted Reverse Cycle Refrigerated Refrigerated air conditioners have two separate mechanical parts, an outdoor compressor and an indoor unit/fan coil. The outdoor compressor unit compresses refrigerant gas into a liquid state to allow the refrigeration effect to take place, exactly the same way as does your home refrigerator. The compressed gas is transferred into the indoor unit. The indoor unit basically consists of a fan and a heat exchange coil. The fan is connected and then controlled by a room installed thermostat that draws the air from inside the home, passes it through a filter and then recirculates throughout your home approximately 10 times each hour. Ducted refrigerated air conditioning units are normally positioned inside the roof, as well as an inverter unit outside the house (usually on a side wall) with ducting throughout the roof space to direct air into the rooms of the home.

How much will it cost?
Ducted Evaporative Supply and Installation – $3,000 to $6,000   
*This is approximate and could vary depending on the size of your home, number of ducts and quality of brand. Evaporative air conditioners generally use much less energy to cool than refrigerated air conditioners. They are the cheapest form of whole of home cooling. They will run from as little as 3 cents per hour for your whole home. The low running costs and low installation costs are a big reason why evaporative cooling is very popular.


Ducted Reverse Cycle Refrigerated Supply and Installation – $5,000 to $20,000 *This is approximate and could vary depending on the size of your home, number of ducts and quality of brand. Ducted reverse cycle air conditioning is generally much more expensive to run than evaporative cooling. A ducted system cooling a whole home may cost more than $1 per hour to run. This amount can be significantly reduced through the use of smart zoning to reduce energy wastage.
How much water is used?

Ducted Evaporative
All evaporative air conditioners use water to produce the cooling effect.
The amount varies with the size of the air conditioner, the amount of cooling selected, and the ambient conditions.
Braemar and Breezair units have unique, market leading water management features which keeps the system clean by minimises water loss through dumping


Ducted Reverse Cycle Refrigerated
Refrigerated units do not use water to cool.

What are the differences in circulation?

Ducted Evaporative
Evaporative air conditioners constantly draw clean fresh air into the home rather than circulating the air.
Because water is used in the cooling process, the air will have added moisture.


Ducted Reverse Cycle Refrigerated
Refrigerated air conditioners continually recirculate the air.
This cooling type removes moisture from the air as it cools.
It can have a drying effect.

What is the temperature reduction?

Ducted Evaporative
The performance will vary depending on quality of unit. As a general rule, a good quality evaporative cooler is capable of bringing the temperature down by a maximum of approximately 12°C from the outside temperature.
Sizing your unit correctly, and purchasing a good quality brand will optimise performance.
Our expert team will show you how. Evaporative cooling works best in hot, dry conditions. These conditions are typical to Victorian Summers.


Ducted Reverse Cycle Refrigerated
Is capable of bringing the temperature down by a maximum of approximately 25°C (45F) from the outside temperature.
Note: this is largely dependent on the outside air temperature and how long the system has been running and the correct sizing of the system to cool the required area.
Sizing your unit correctly, and purchasing a good quality brand will optimise performance.
Our expert team will show you how.

Considerations

Ducted Evaporative
Evaporative air conditioners constantly draw clean fresh air into the home rather than circulating the air.
Windows or doors must be left open to allow the hot air to be pushed out and replaced with cool fresh air.


Ducted Reverse Cycle Refrigerated
Because the cool air is recirculated, windows or doors need to be closed to prevent the cool air from escaping.

HEATING & COOLING

What are the options?

Ducted Gas Heating with Integrated Refrigerated Air Conditioning
Fixed gas heater which uses natural or LPG gas to heat the air, combined with a refrigerated air conditioner which uses the same ducts to distribute cool or warm air into the home.
These systems typically use the same controller to control both heating and cooling.


Ducted Reverse Cycle Refrigerated Air Conditioning
Ducted reverse cycle refrigerated air conditioners consist of a compressor, fan and heat exchange coil and use a refrigerant to cool or heat the air.


Ducted Gas Heating with Separate Evaporative Air Conditioning
Fixed gas heater which uses natural or LPG gas to heat the air which is then distributed through ducts into the home.
The separate evaporative air conditioner uses only air and water – to cool air through the simple principle of evaporation of water.
These systems typically use the same controller to control both heating and cooling
