Flued Gas Heaters

Experts in Flued Gas Heater Services

Flued gas heaters are a reliable way to bring consistent warmth and comfort into your home.

What sets them apart is their built-in flue, which safely channels combustion gases – such as carbon monoxide, nitrogen dioxide and water vapour – outdoors, making them a safer choice for indoor use.

These heaters can operate using either natural gas or bottled LPG (liquefied petroleum gas), offering flexibility based on your home’s existing fuel source. While many are fitted into an existing fireplace for convenient flue installation, flued gas heaters can also be installed in other areas with proper ventilation.

Whether you're looking to warm up a spacious living area or just need focused heating in a smaller room, there’s a flued gas heater to suit. Metropolitan Heating and Cooling can help you choose and install the right unit for your space, ensuring efficient performance and safe operation year-round.

What’s the Difference Between Flued and Unflued?

When choosing a gas heating system, it’s important to understand the key differences between flued and unflued gas heaters. The main difference comes down to how they handle exhaust gases.

A flued heater uses a flue to vent these gases safely into the outside atmosphere, helping to maintain fresh air inside your house.

Unflued gas heaters, on the other hand, release combustion by-products directly into the room. While these unflued systems are often portable and provide strong heat output, they require excellent ventilation to be used safely. Without proper airflow, unflued heaters can contribute to condensation, dampness, and even mould.

Flued heaters are fixed in place and often installed in existing fireplaces, making them ideal for long-term use. Unflued heaters are more flexible but come with safety considerations.

If you’re unsure which option suits your home best, simply request a consultation with Metropolitan Heating and Cooling – we’ll help you choose the right heating solution.

Understanding the Different Types of Flued Heaters

Flued gas heaters are generally available in two main types: radiant and convection.

Radiant models feature an open flame visible behind a metal grate, creating a warm, glowing ambience while directly heating nearby surfaces and people. Many modern versions now include a built-in fan to help circulate warmth more effectively throughout the room.

Convection flued heaters, in contrast, warm the air by drawing it in, heating it internally, and then pushing it back out to evenly heat the entire space. Both styles connect to a natural gas supply and continue to be a popular choice for their efficiency and reliability in colder climates.

Whether you prefer the direct heat of a radiant model or the broader coverage of a convection unit, Metropolitan Heating and Cooling is here to ensure your chosen system is professionally installed for optimal comfort and peace of mind.

Benefits of Flued Gas Heaters

Flued gas heaters offer an ideal balance of safety, comfort and energy efficiency, making them a smart choice for today’s homes. These systems are designed to deliver powerful warmth while preserving indoor air quality and keeping energy bills manageable.

Take a look at the key advantages:

• Safe indoor air: The built-in flue is what sets these heaters apart – it safely vents harmful gases like carbon monoxide outside, ensuring clean, healthy air indoors.
• Added protection: For extra peace of mind, pairing your flued gas heater with a carbon monoxide detector can provide early warning of any potential gas leaks.
• Impressive efficiency: Leading models, such as the Rinnai EnergySaver, boast energy ratings up to 4.8 stars, combining performance with low environmental impact.
• Affordable heating: Flued gas systems typically cost less to run than reverse cycle units, helping you save without sacrificing comfort.
• Inviting ambience: Radiant versions replicate the look and feel of a traditional fireplace, adding charm along with warmth and easy remote operation.
• Plenty of choices: With a wide range of styles and features – including fixed, radiant and convection models – there’s something to suit every space.
