Buying Guide

Buying Guide

We understand that buying a wood heater can be a big decision. To help transform your home into a warm, comfortable living space in winter, here are some simple considerations to find your perfect heater.

Quick Questions to Ask Before Buying a Wood Heater

  • How many rooms would you like to heat? How big are the rooms?
  • Is your home single or double-storey? Is it well insulated?
  • Will you be using other types of heating?
  • Do you have an existing fireplace?
  • Where do you live? Your region's climate?
  • Is the wood heater you’re looking for certified by the Australian Home Heating Association?
  • Where will the wood come from and how much will it cost?

How many rooms do you want heated? How big are they?

Determining the size, space and layout of your home requirements would help you decide what type of heating style and coverage is suitable. Convection heaters are ideal for rooms or homes with standard ceiling heights, while radiant heaters are great for rooms with high ceilings. If your home is well insulated, you may not need too powerful a heater. But also consider the layout of your home, and if you will be using other types of heating appliances.

Do you have an existing fireplace?

An existing fireplace means you can upgrade with our range of inbuilt insert heaters. We also have a wide range of freestanding wood heaters or zero clearance heaters for homes that don’t.

How would you like your heater installed? Is your home single or double-storey?

The type of home you have will be an important consideration to your wood heater installation requirements. Your heater could be installed as a 45 degree wall penetration, floor penetration, cathedral ceiling install or an insert installation. Each installation type will help determine the length of flue kits, roof flashing and extra components needed for your wood heater. Read more about the different installation types and requirements.

Where do you live?

If you live on the coastal region of Queensland, you may only need smaller heater coverage. If you live in a colder the regions like Tasmania or Victoria, you should consider a wood heater with higher coverage for a small room. If you’re in a bushfire prone area, you’ll need to consider a BAL rated roof flashing. There's plenty to consider based on where your home is.

Is your wood heater certified by the Australian Home Heating Association (AHHA)?

All wood heaters must adhere to the Australian Standard for wood heater emissions (AS/NZS 4013) to ensure that they are clean burning and environmentally responsible. All of the wood heaters sold at Barbeques Galore are certified and complies with the AS/NZS 4013. If you're looking at other wood heater brands, you can visit the AHHA website for a list of certified wood heaters.

Basic Installation Kit

Basic Installation Kit

While shopping for your wood heater with us online, you will need to manually add the installation components. These components will vary, based on your home’s requirements; such as whether you're replacing a current wood heater, or installing one for the first time in a single or double storey home. To make it easy for you, we have recommended some of the more basic components you may need on this page.

In most installations, you will need a flue kit, a roof flashing, and maybe a hearth. There could also be other components that we may not have available on our website, but we’ll help you when you come in-store to collect your order.

Recommended roof flashing

Every flue system must be flashed (sealed) at the point where it exits the roof lining. The choice of roof flashing depends on your roof type – whether it is a tile or metal roof; and if you live in a bushfire prone area.

The following roof flashing are recommended for your selected wood heater:

Recommended hearth

Wood heaters can expel a lot of heat, so a hearth is a great way to protect your home if you have carpet, timber and any combustible flooring. It is also a great way to limit cleaning wood or ash to the direct area beside your heater. Check your heater’s hearth clearance requirements to determine which size will suit your home.

The following hearth are recommended for your selected wood heater:
