Control your Heat With a Ducted Heating System!

Coldflow recommends the energy efficient Braemar range. Top of the range energy efficiency is achieved from the 3.7 – 5 .6 star gas heaters. Using less gas to heat your home means extra dollars in your pocket.

Gas ducted heating is adaptable to the option of introducing cooling through the same outlets. Commonly referred to as gas add on, a cooling fan coil is incorporated at the design stage allowing you the versatility of cooling for the hot summer months.

Zone control may also be introduced to further reduce running costs and allowing you to decide which areas or rooms to heat or cool by switching the zones on or off.

What do Gas ducted heating systems consist of?

  • A furnace fueled by natural gas or liquefied petroleum gas (LPG). Air is drawn in by a fan, and passed over a heat exchanger to warm it. Furnaces are 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 a 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.
