What Size Gas Ducted Heating Unit Do I Need?

You can always wrap yourself to feel cosy, but nothing beats a nice warm home in winters. Although there are several heating options, a whole-of-home heating solution is the way to go. That’s exactly what you get with ducted heating. But we often come across a query about “what size ducted heating unit do I need.”

Gas Ducted Heating in Melbourne

Gas in Australia is relatively cheaper than electricity per unit. Due to the abundance of natural gas, a central ducted heating system is one of Melbourne’s most cost-effective, efficient, and popular heating methods. The system works by drawing the air inside your home and heating it through the heat exchange before distributing warm air with the help of a ducted system. This system is mainly installed under the house, in the roof, or out of the house against an exterior wall.

So, What Size Gas Ducted Heating Unit Do I Need In Melbourne?

Given that not every home is the same size, there is no one-size-fits-all gas ducted heating Melbourne unit. Having a ducted heating unit too small could mean you won’t get to enjoy a toasty and warm house in the winters. On the other hand, a unit too big could increase energy bills, and the system will short cycle frequently. You will also need to understand the different kW of heating units and their star ratings, which we explain as well.

First, you need to measure your home. It will allow you to know what kilowatt (kW) ducted heating unit can provide adequate warmth and has less running cost.

Suppose that you have three rooms: A, B, and C. You will need to measure each room’s width and length with a measuring tape. Once you have the length and width of room A, multiply them to get the area in square meters. Next, do the same with rooms B and C. Finally, add square meters of three rooms to get the total area of your home.

Now that you have the total area of your room, you’ll need to find the right size ducted heater. As a general rule of thumb, 1 kW output is required to heat every 10 m2. Therefore, if the total area of your home is 200 m2, a ducted heating unit with a minimum of 20 kW output could provide sufficient whole-house heating.

It is essential that you consider these 3 factors that could affect the ducted heating unit’s size needed for your home:

  1. Insulation
  2. Number of windows and their state (ensure there is no leakage)
  3. Ceiling height

Many homeowners often ignore the importance of ceiling height. Hot air floats upwards because it is less dense than cold air. That’s why it is essential that you consider the ceiling height factor before finding the right size heating unit.

What is The Energy Star Rating?

The energy star rating on a gas ducted heating unit helps determine the system’s energy efficiency (how much gas it uses). If the star rating is higher, it means the unit is more energy efficient. Therefore, choosing a unit with a better energy star rating means more considerable annual savings.

On average, a one-star increase in the energy rating means usage savings of about 10% – the more stars, the better savings. The minimum star rating for a gas ducted heater is 1 star. If you want a highly efficient heating system with surprisingly low running cost, you may want to consider Braemar ECOSTAR® 7 Star – it is the world’s first 7 Star gas ducted heater. In addition, you may want to consider choosing a new unit from the leading ducted gas heating brands in Australia.

Why Selecting The Right Size Ducted Heating is Important?

As there are different styles of homes, ducted heating systems come in a variety of sizes. That’s why the thinking of “bigger is always better” doesn’t make a lot of sense when it comes to choosing the right size ducted heating Melbourne unit. With a properly sized heating unit, you can expect the following benefits:

  • Improved energy efficiency
  • Improved cost-effectiveness
  • Improved comfort
  • Less possibility of a breakdown
  • Reduced possibility of expensive repairs
  • Enhance lifespan of the system

Let’s take a look at why the size of a ducted heating unit matters a lot:

The Problem With Oversized Ducted Heating Unit

If you choose a heating unit too big for your home, it can provide too much warm air in a short burst. It could make your home feel too warm, followed by temperature fluctuations. A heating unit too powerful for your home could short-cycle a lot because it will be warming the space too quickly. It could also increase the possibility of a breakdown or expensive repairs.

The wear and tear could result in shortening the lifespan of the unit. Last but not least, frequent short cycling could lead to high heating bills.

The Problem With Undersized Ducted Heating Unit

The most obvious issue with an undersized gas ducted heating unit is that it could be running non-stop to provide the desired warmth and comfort. However, chances are, it could fail miserably at doing that because of the system’s inability to draw the cool air inside the house and warm it properly. Moreover, constant running will increase the heating bill and maximise the strain put on the heating unit and increase the likelihood of an unexpected breakdown.

Consult With A Professional

From measuring the size of each room to considering other factors, you have to be precise in everything to ensure you find the right-sized ducted heating unit. Instead of a half-baked DIY job, consult with a trusted professional to evaluate your home and help you select the right-sized unit that could provide adequate heating without compromising your comfort or budget.
