Ducted gas heating is one of the cheapest and most efficient ways to heat your home. But how much does it cost? We'll go through the cost of running a ducted gas heating system, installation, maintenance and repairs.

Gas Ducted Heating Running Costs

Gas ducted heating is an attractive option for whole home heating, especially due to the running costs. In almost all situations, gas ducted heating has the cheapest running costs compared to any other system. Low-efficiency gas ducted heating is still efficient compared to other heating systems like electric heating or the heating function on a split system air conditioner. High-efficiency systems can reduce running costs further by up to $200 a year.

Gas Ducted Heating Installation Costs

The cost of a gas ducted heating unit generally varies between $1500 and $3500 depending on the capacity of the unit, the energy efficiency and additional features such as zoning which allows you control over heating certain sections of the home.

The installation of the unit is made up of a combination of labour and parts. These costs are much more variable and will be unique to your home. Factors such as the size of your home, the configuration and the construction of your home will all affect the cost of the installation and must be quoted on an individual basis. Quotations for installation will take into account things like the number of vents to be installed, the distance ducting needs to be run and ease of access to crawl space in the roof or under the house.

Gas Ducted Heating Repair Costs

Repair costs for gas ducted heating are very reasonable compared to other styles of units. They will be more expensive than small portable units, however, many small gas heaters are sealed systems and cannot be repaired if the break and replacement is the only option.

The amount of labour required will depend on the parts being replaced and your particular unit configuration and ease of access. The cost of parts required for the repair will depend on the particular issue, but also on the age of the unit, the brand, whether parts are still in production and whether aftermarket parts are available.
