EZYAIR Specialise in Split System Air Conditioning

At EZYAIR, we specialise in Split system air conditioning.

The reason why we are able specialise in such a specific niche of the heating and cooling market is because they are a popular choice not only in the Australian, but also the American, German, Austrian, Swiss, Swedish, Danish and Japanese markets.

So, why are split systems so popular?

Well, for a start - they are the most energy efficient forms of heating available. Almost incidentally, they cool too! They not only remove humidity (water) from the air, but they will clean and purify the air as well.

And they can operate in almost complete silence.

At EZYAIR, we strive to provide our customers with the most relevant information to enable them to make an informed decision. If you would like more information, please contact us by phone: 1300 399 247 or via our contact page!

Apartment Split System installation

EZYAIR specialise in the installation of split system air conditioners into a high rise apartments in Melbourne.

Here is a picture of a job we recently did in Fitzroy... the fourth unit we have installed into the block.

Split System Heating - More Efficient than Natural Gas.

Gas Vs Split System Heating

This procedure will explain how to calculate the running costs of natural gas heating appliances and split system air conditioners, then illustrate how to compare their running costs and efficiency when both are used as heaters.

How to Calculate the running cost of a Heating Appliance

1. Find out the appliance's input power in MegaJoules or Kilowatt. (Depending if it’s a gas appliance or split system).
2. Multiply the input power by the energy Tariff (MJ for gas / Kilowatt for electricity).

Measurement	Cost (Peak)	Supplier	Date of Publication
Gas MegaJoule (MJ)	$0.03 per MJ	Origin Energy	September 2013
Electrical Kilowatt (kW)	$0.23 per kW	Red Energy	September 2013

Gas Appliance Consumption Analysis

Gas Appliance	Input of Energy	Output of Heat	Cost per hour
Rinnai Energysaver 309FT	9.5MJ/h	2.9kW	$0.28
Rinnai Energysaver 561FT	16MJ/h	5.0kW	$0.48
Rinnai Energysaver 1004FTR	24MJ/h	8.6kW	$0.72

Split System Air Conditioning Analysis

Split System	Input of Energy	Output of Heat	Cost per hour
Panasonic CS/CU-E09PKR	0.75kW/h	2.6kW	$0.17
Panasonic CS/CU-E189PKR	1.69kW/h	5.0kW	$0.38
Panasonic CS/CU-E28PKR	2.64kW/h	8.0kW	$0.60

Result - Split System air conditioners are more efficient heaters than gas appliances.

As you can see from the analysis above, split system air conditioning can be up to 30% more efficient heaters than natural gas.

The Reason

Natural gas heating appliances burn natural gas to create a flame. This flame then heats up a heat exchanger within the gas heating appliance and air is drawn over the heat exchanger to add heat to the air. This is a very basic form of heat exchange and not very energy efficient.

Split systems compress refrigerant to create heat. As when a refrigerant is compressed, it get’s hot. The air is then drawn over the coils, and the air is heated. All the electricity does, is run two small fans (one in the indoor unit and one in the outdoor unit) and a small compressor. All of the hard work is done by a thermodynamic process of the refrigerant changing state from a liquid to a gas.
