    Your Gas Heater FAQs

    Give Winter the Cold Shoulder with a Gas Heater!

    Which type of gas heater is best?

    Winter nights in Australia can get surprisingly cold, but the right gas heater can make your home feel warm, cosy, and inviting. At Harvey Norman, you’ll find the best wall and portable gas heaters from trusted brands like Rinnai, Omega Altise, and Bromic.

    There are two main types of gas room heaters to choose from:

    • Gas Convection Heaters – Warm the air and circulate it throughout the room, making them a great choice for heating larger areas.
    • Radiant Gas Heaters – Provide instant, direct heat to you and your surroundings – perfect for smaller spaces or when you need warmth fast.

    Natural Gas vs LPG – Which option is right for my home?

    When choosing between natural gas or LPG, you need to consider your home’s set-up, location, and how often you plan to use the heater. Here’s a quick guide to help you compare:

    • How It’s Delivered – Natural gas is supplied through underground pipes, so it’s ideal if your home is already connected. LPG comes in bottles, which is great for rural properties or homes without a gas line.
    • Where It’s Used – Natural gas is more common in cities and suburbs with established infrastructure, while LPG is often used in regional or off-grid areas.
    • How Convenient It Is – If you’re already connected, it’s hard to beat the set-and-forget convenience of natural gas. If not, LPG offers more flexibility, but you’ll need to stay on top of refilling bottles.
    • How Much It Costs – Natural gas is generally cheaper for regular use, though there’s usually a daily supply fee. LPG might cost more per refill, but it can be an affordable alternative if you’re only using the heater occasionally.

    How do I choose an indoor gas heater?

    Choosing the right indoor gas heater isn’t just about deciding between LPG or natural gas. From how cold it gets where you live to the features that make it more efficient, here are a few key things to keep in mind when shopping:

    • Match the Heater to Your Room Size – Larger rooms need more heating power, so check that the heater can warm your space effectively.
    • Check the Heating Capacity (MJ/hr) – This tells you how much heat the unit can produce – higher numbers mean more warmth.
    • Consider Your Local Climate – If you live in a particularly chilly area, opt for a higher-capacity heater that can handle lower temperatures.
    • Choose the Right Flue Type – Flued heaters vent gases outside for better air quality. Unflued models are portable but require good ventilation and aren’t suitable for bedrooms or bathrooms.

    Are gas heaters cheap to run?

    Gas heater running costs are a hot topic every winter! Gas heating is a cost-effective and reliable way to stay warm, especially compared to some electric alternatives, but your running costs will depend on several factors, like how often you use it, the size of your space, the heater’s energy efficiency, and local gas prices.

    To stay cosy without burning through your budget, look for energy-saving features like thermostats, programmable timers, and automatic shut-off that help you heat your home more efficiently.

    Are gas heaters safe to use indoors?

    Gas heaters are perfectly safe to use indoors if you follow the right precautions. Most new models include built-in safety features that offer extra peace of mind, such as:

    • Tilt Switch – Automatically shuts off power if the heater is tipped over.
    • Oxygen Depletion Sensor – Cuts the gas supply if oxygen levels drop too low.
    • Flame Failure – Instantly stops gas flow if the flame goes out, preventing gas build-up.

    Remember to let fresh air in by ventilating the space or cracking open a window, and keep the area around the heater tidy and free of anything flammable. With the right safety features and a few simple steps, gas heaters are a safe, effective way to stay warm and toasty all winter long!
