Frequently Asked Questions


Can I attach Evaporative Cooling to my Heating?

No, Evaporative cooling systems have much more air volume than ducted heaters.

Therefore, the ducting needs to be much bigger and the outlets go in different position in the room than the heating vents.

What is the difference between air-conditioning systems and evaporative cooling?

Air-conditioners, condition the same air and have a return air and supply registers.

Evaporative coolers don’t condition the air, they change air, so they bring in cool air and push out hot air via open windows (so no Return Air)

What does the term “split system” mean?

Split system simply means that the system is “split in two”. There is an indoor unit and an outdoor unit.

Some people think this means that the system will heat and cool.

Most systems do both heating and cooling

A Split system can be a wall type (most popular) or indeed a ceiling cassette, a ducted system or a floor console type.

What is zoning?

Zoning applies to ducting systems. It enables the user to turn “Off” areas of the home when no-one is using it, and turn “On” the other areas that are being used in the home.

This saves the end user significantly in energy usage and costs.

How does a High Efficiency ducted heater save me money and how much?

A standard efficiency heater, is approximately 70% fuel efficient. That means that 30% of all the heating generated goes to outside, via a flue (Older system can be much less than the 70%)

High Efficiency heating systems can be as much as 96% fuel efficient! Much less heat is emitted via the flue thus saving real money.

If I have a large split system installed will it condition the entire home?

No, oversizing a split system, can be just as bad as a unit which is too small.

A split system is a room air-conditioner and designed to condition the room that it is in.

Depending on the design of the home you may however, get some spill over effect into other rooms.

What is a Multi-split?

A multi split means that you would have one outdoor unit connected to several indoor units. You have individual temperature controls in each room.

It is an economical way to go as you only pay to run one condensing unit for all rooms.

What is an Inverter type unit?

Inverter is the name of the technology that allows the capacity of the unit to increase and decrease according to the demand on the home.

There are three main benefits to “Inverter” compared with standard air-conditioners:

  1. The system will be much cheaper to run (up to 50% )
  2. The system will be much quieter (both indoor and outdoor units)
  3. The system will provide a much better comfort level. This is because the compressor will adjust itself automatically and not simply turn On and Off according to room temperature
