Ducted Heating vs Split System

Getting a heating system installed in your home in Melbourne is a must. If you are thinking whether ducted heating or a split system can suit your property, here is a guide.

Property owners across South Australia depend on their central heating systems for warming their spaces. It becomes important to keep the family members comfortable when the temperature drops outside. You can call a heating system to be effective only when it can generate and spread warm air all through the interior space, irrespective of the level of temperature drops outside. When you plan to install a heating system in Melbourne, you might be wondering whether to choose a ducted heating system or a split system. Before we compare these two systems, let us gain some basic details about them:

Ducted Gas Heating

What Does Ducted Gas Heating Mean?

Gas ducted heating is something referred to as GDH, and it functions either using LPG or natural gas. This system will have an external furnace. This furnace will heat the cold air by passing the air via a heat exchanger. It will do this process before pumping the air to other areas of your home through a system of outlets and ducts.

You should know the components that will be part of a ducted heating system. This system will have many different components. All these components work in conjunction with other components for gathering cold air, warming it and sending it through ducts into the spaces that are open in your property. To properly work, a ducted heating system should have a heating unit. Also, it should have register vents, grilles, a thermostat and insulated ducts. This system is a pass-through system. It means that it cannot work if even a single component is not present.

How About Running Cost?

When you take the case of an average home in Australia, studies show that homeowners spend nearly 40% of their energy costs on heating and cooling their property. When you compare gas ducted heating and split systems, you should consider the annual cost an essential factor. The thing to remember here is that many different factors go into deciding the annual running cost of a gas ducted heating system. Some of these factors include the energy efficiency of your heating system, your home size, and the insulation in your property. You can get to know the energy efficiency of any heating system before buying it with the help of the energy star rating given to the system. From the table below, you can somewhat get an idea of the annual running cost of a gas ducted heating system:

House Size
Star Rating Small House (100 m2) Medium House (160 m2) Large House (220 m2)
3 Star $835 $1250 $1645
4 Star $735 $1095 $1445
6 Star $635 $950 $1250

 

So, irrespective of the size of your home, the better the star rating you choose, the more will be your savings on the energy costs.

You might think that the average costs mentioned above are high. But, you can follow certain measures to ensure that you do not get high electricity bills. For instance, you can consider weatherizing your home to prevent air leaks. Go for windows with double or triple glazed options. Also, ensure that your property remains properly insulated to prevent leakage of heat. When the heat leaks, the ducted heating system will have to work hard to heat your rooms. In turn, you will have to spend too much on electricity.

Split System

What Is A Split System?

With the basic knowledge you have gained about the ducted heating system, you should know some basic things about the split system as well, isn’t it?

When talking about the split system, it is one of the two types of reverse cycle air conditioning systems. Yes, want to know the name of the other type? It is a ducted reverse cycle. As the name of the split system reverse cycle denotes, it is a two-in-one system. It means that during summer, it will cool your home, while in the winter, it will keep your home warm.

When you take the case of a split system, it has been designed to be more energy-efficient as compared to the ducted heating system. The reason is that it focuses on a single room in your house as against the entire house heating or cooling. Also, as compared to the other system, it will not occupy much space in your home. Apart from heating and cooling your home, it can also dehumidify and filter your home, thereby making the air around your home clean, healthy, and pleasant.

When talking about the split reverse system, you should know about the components in it, isn’t it? The reverse cycle air conditioning is taken care of by a device commonly referred to as a Heat Pump.  It works under the heat exchange principle. This heat pump takes care of the cost of absorbing the heat from the outside air, even during the cold winter nights and then transfers it inside. Also, this system uses refrigerant gas for heat exchange, while other systems create heat with the help of electricity. The heat pump in this system again will have four components. They are evaporator, restriction device, condenser and compressor.

Running Cost

The average cost you will have to spend for running a reverse split system for heating your home will differ based on different factors. For instance, the size of the system that is measured in kW is an essential factor. Another key factor is the particular area in Australia your home is located. Here is a table to give you an idea:

 

City Size
  2-2.5 kW 2.5-5 kW 4-6kW
Canberra $197.75 $259.22 $405.67
Hobart $257.25 $337.22 $527.73
Melbourne $213.50 $279.87 $437.98
Perth $97.92 $123.84 $189.50

Conclusion – Which is The Best?

When you compare gas ducted heating vs reverse cycle air conditioning, the decision purely depends on your personal preference, your budget and your usage pattern. When you take the case of reverse system, it will cost you low upfront. But, during winter, you will find a ducted heating system more suitable for cosy heating. When talking about the quality of air, as compared to ducted gas heating, the other system can ensure the best quality internal air for your family to remain safe. So, which one have you decided on?
