Gas Furnace Heating

Gas central heating is a ducted system, which means that heated air is distributed throughout the home by a network of ducts, usually in the roof cavity or under the floor.

Air is heated in a heat exchanger, which is heated by clean burning gas. The warm air enters each room through an outlet located in the floor, ceiling or wall.

All gas central heaters have a star rating which is a guide to their energy efficiency. The AGA star rating label shows you the appliance’s efficiency. This is an Australian approved standard for evaluating the energy efficiency of an appliance. The more stars, the more energy efficient the unit.
