Gas Ducted Heating Installation Melbourne

Ducted gas heating systems are traditionally the most common form of whole-of-home gas heating.

These systems draw air from inside the home through a heat exchanger for rapid warming and distribution through outlets in the floor or ceiling

  • Highly efficient
  • Cost effective
  • Requires little maintenance
  • Uses natural gas or liquefied petroleum gas (LPG)

These systems are adaptable to the option of introducing cooling through the same outlets. Commonly referred to as ‘gas add-on’, this involves a cooling fan coil being incorporated at the design stage, allowing you the versatility of receiving cooling from the same system during the hot summer months.

Zone control may also be introduced to further reduce the running cost of ducted heating systems, and allow you the option of deciding which areas or rooms to heat or cool by switching the zones on or off.

These options, combined with the ducted heating specials we offer our Melbourne customers, make it a cost-effective gas central heating solution.

Gas Ducted Heating Melbourne

What do the systems consist of?

  • A furnace fueled by natural gas or LPG. Air is drawn in by a fan, and passed over a heat exchanger to warm it. The furnace is usually installed in the roof space or externally, but can also be placed under the floor or even in internal cupboards if space is limited.
  • Ducting distributes the heated air through the home. It is usually laid above the ceiling or under the floor, but can be placed between floors or in other cavities, depending on available room.
  • Registers (also called ‘outlets’ or ‘vents’), attached to the floor or ceiling, or sometimes the wall, direct warm air into rooms. Provided ceiling registers are correctly positioned, and of appropriate design, they will provide a similar heating effectiveness to floor registers. Floor registers are usually located near outside walls to allow heat to fully flow back through the house to the return air grille. Ceiling registers should be located centrally in a room, or between the center and external walls.
  • A return air vent (grille) recirculates air to the furnace, beginning the cycle again. The grille should be located at or near floor level or in ceiling or roof.
