How Much Does It Cost to Run a Gas Heater?

When the chill of winter rolls in, nothing beats the warmth of a reliable gas heater. It’s the go-to solution for staying warm on those cold evenings. But here’s the burning question: how much does it cost to run a gas heater per hour?

In this blog, we’ll break down everything you need to know. From the typical gas heater running costs to tips for managing your energy bills, we’ve got you covered.

Are Gas Heaters Expensive to Run?

Gas heaters are not expensive to run. In fact, they are more cost-effective than electric heaters.

To understand this better, let’s compare the cost to produce the same amount of heat using both electric and gas heaters. Heat output is measured in megajoules (MJ), and a typical moderate setting on a gas heater uses around 8.5 MJ per hour.

To generate the same 8.5 MJ of heat, an electric heater would need to run at 2.36 kilowatts (kW). Based on Sydney’s current average energy prices:

• Electricity costs around 32.5 cents per kWh (Kilowatt-hour), so a 2.36 kW heater would cost about $0.77 per hour to run.
• Natural gas costs approximately 3.6 cents per MJ, meaning a gas heater at 8.5 MJ/h would cost just $0.31 per hour.

This shows that if you’re getting the same amount of heat, gas heater cost per hour is cheaper than electric ones.

Larger gas heaters (like those using 25 MJ/h) can cost up to $0.90 an hour. They’re made for heating large spaces and generate heat quicker, so you do not need to run them for long.

And even at that higher setting, they’re still more cost-effective than an electric heater producing the same heat, which would need about 6.94 kW of power and cost around $2.25 per hour to run in Sydney.

How Much Gas Does a Gas Heater Use?

As mentioned earlier, a gas heater on a moderate setting usually uses around 8.5 MJ per hour. That said, gas usage can vary depending on the type of heater and how you’re using it. Here’s a guide to give you an idea:

• Portable Gas Heaters: These typically use between 8 to 12 MJ per hour.
• Ducted Gas Heaters: A larger, more powerful system can use 20 to 25 MJ per hour.

What Type of Gas Heater Should You Choose?

There are a few different types of gas heaters available on the market. Let’s take a closer look at the pros and cons of each to help you determine which one best suits your needs:

Portable Gas Heaters

• Pros: Portable gas heaters are highly affordable, easy to move around, and quick to heat small rooms or specific areas of the home.
• Cons: These heaters are only suitable for small spaces and may not provide sufficient warmth for larger homes.
• Cost: They are cheaper to run compared to other types, especially for targeted heating.

Ducted Gas Heaters

• Pros: Ducted gas heaters are perfect for larger homes, providing even and consistent heating throughout multiple rooms. They deliver warmth quickly while keeping your energy use balanced.
• Cons: The initial installation cost can be quite high, especially when considering the complexity of setting up ducts and vents. Additionally, the system requires a flue or ventilation, which can be an added expense.
• Cost: While they are generally more expensive to run due to their higher energy usage, they offer long-term benefits in heating efficiency for large homes, making them a good investment.

Gas Log Fires

• Pros: Gas log fires provide both warmth and ambience, making them a perfect choice for living rooms, open-plan spaces, or any area where you want to create a cozy atmosphere.
• Cons: These systems come with high maintenance requirements, including cleaning and servicing. Additionally, the installation costs can be high, as they require more complex setups compared to simpler heater models.
• Cost: Gas log fires are similar in running costs to ducted heaters but come with the added value of creating an attractive focal point in your home.

Flued Gas Heaters

• Pros: Flued gas heaters are great for larger, well-ventilated rooms, providing continuous airflow and a steady supply of warmth.
• Cons: Installation cost for flued gas heaters is high, as they require proper flue setup and a secure venting system. Additionally, they need to be installed in rooms with adequate ventilation, limiting their placement options.
• Cost: Though the upfront installation cost is high, flued gas heaters are cost-efficient in the long run for large spaces, as they can maintain a consistent and comfortable temperature with minimal energy waste.

Tips to Reduce the Running Costs of Your Gas Heater

While gas heaters tend to be budget-friendly, there are a few smart ways to make them even more cost-effective. Here’s how:

• Use a Timer: Set your heater to turn off after a few hours to avoid wasting energy. This small habit can make a noticeable difference over time.
• Seal Gaps: Ensure windows and doors are properly sealed. This keeps the heat in and reduces the need for your heater to work harder.
• Lower the Thermostat: Keep the room just warm enough. Lowering the temperature by a few degrees can lead to significant savings without sacrificing comfort.
• Regular Maintenance: Have your heater serviced annually to ensure it’s running efficiently. A well-maintained heater uses less energy and performs better.

Final Thoughts on Gas Heater Costs

In conclusion, gas heaters are a great option for heating your home efficiently and affordably, especially when compared to electric models. Their low operating cost and strong performance can keep you warm through winter without putting pressure on your budget.

Now that you know the costs involved, you can make an informed decision about the best heating option for your home.
