Ducted split systems or perhaps more simply “ducted air conditioning” works by having a central location where the air is treated, then sent by fans through a system of ducts into each room. Ducted air conditioning is more expensive to install due to the cost of running the ducting but is a better solution than split systems where multiple rooms or large areas are involved. Ducted air conditioners are also quieter than split systems because all the motors are outside of the house or in the ceiling. Ducted air conditioning can be zoned. Zoning allows different people in different rooms to dial in different temperatures. Zoning also improves efficiency by turning of zones that are not currently in use.
Although ducted systems tend to cost more upfront, they are generally more efficient at cooling large areas than split systems. Ducted systems tend to be more aesthetically pleasing. Inside the house, a ducted system is almost invisible. The only way you will know it’s there is if you see the vents or the controller on the wall. Most units sold are “reverse cycle”.
Reverse cycle is an air conditioner in which the refrigeration cycle can be reversed, producing heating instead of cooling. It’s really two systems in one that work in a most efficient way together. When the reverse cycle unit is in cooling mode, it works like a normal air conditioner.
A ducted gas system is where heated air is created by a gas burning unit located outdoor and the heated air is passed through the house via a series of duct work and then through an outlet in the floor or wall.
The advantage of ducted gas heating systems is efficiency. Gas heaters are in general more efficient than reverse cycle air conditioners at producing heat. The downside of ducted gas systems is that they do not cool and need to be coupled with a separate cooling systems if this is required. The outdoor units required for ducted gas technically simpler than outdoor units for reverse cycle air conditioners and are there cheaper to install.
As the name implies, add on cooling is for homes that have existing ducted gas heating but want cooling for the summer months. It works with your existing gas ducted system to keep you cool and comfortable all summer long. The add on system will use the existing ducting to deliver cold air when needed without having to go to the expense and inconvenience of running new ducting throughout your home.
A split system is ‘split’ into two units. One that is inside, and one that is outside. Split systems are relatively easy to install since no ductwork is required. These systems are known for being quiet and energy efficient. With a split system users can choose to mix and match different indoor and outdoor units to match your heating and cooling requirements as well as our internal decor.
A premium split system is set apart from the others because of its advanced set of features. These advanced features vary by unit and by manufacturer. See the page for details.
Hydronic heating using natural convection and radiant heat.Your home or workplace will achieve the warmth you desire without stirring dust and allergens or creating that stuffy feeling many other heating options such as central heating and split system air conditioners create.
The hydronic system simply heats water and moves it through sealed pipes to radiators throughout the home. Hydronic Heating heats water at its source via super energy efficient Gas Boilers. Once used the water is returned to be reheated via a recirculating system. Hydronic heat can be delivered using in floor or wall based systems.
The advantage of hydronic heating is that it is more efficient than reverse cycle air conditioning.
A cooling unit can be added to the hydronic heating system to ensure year round comfort.
An evaporative air conditioner uses evaporation to help cool the air. Hot, dry outside air is pumped through water-soaked cooling pads. As the air is pushed through the cooling pads, the water evaporates and the heat in the air is absorbed, which lowers the air temperature. A fan then pushes the cool air throughout a house via a network of ducts.
Evaporative cooling is much cheaper to operate than reverse cycle air conditioning, but it not as effective as reverse cycle air conditioning on humid days or in humid climates. Air from an evaporative cooler is not recycled so a window or door should be left open to allow the warm air to be replaced by cooler air brought into the house from the evaporative cooler.
Energy created by the heat and light of the sun is called solar energy. Solar power is produced when solar energy is converted into electricity using Photovoltaic cells which are typcially mounted on your roof.
Excess energy that you do not use can be sold to the electricity companies for a “feed-in-tarrif”.
A feed-in-tariff is the amount your electricity retailer pays you for any electricity your solar system generates that you do not use and is fed back into the grid. Feed-in tariffs differ depending on where you live. In Victoria the feed-in tarrif is set each year. From 1st July 2019 the new single-rate minimum feed-in tariff is set at 12 cents per kilowatt hour.
VRV and VRF are interchangeable terms. These units are usually have several (or many) indoor units powered by a single outdoor compressor. These system are similar to a multi-split systems and can the same internal components as a multi-split. What makes these units different is the outdoor units can run at varying speeds depending on the need, whereas most air conditioning compressors either run at a single speed or are turned off.
VRF units have include an inverter and DC motors which facilitate running at different speeds. Variable compressor motor speed and means variable refrigerant flow. By operating at varying speeds, VRF units work only at the required rate to maintain the environment, allowing for substantial energy savings.
