In Victoria, heating accounts for the largest amount of energy used in the home. Upgrading to an electric reverse cycle split system is the most energy efficient, lowest cost heating option available that generates the lowest greenhouse emissions.
Many Victorian homes have both gas heating and reverse cycle air conditioning systems. Using the heating function on your air conditioner instead of your gas heater will save you money without the need to invest in new technology.
Individual split systems are the most efficient as they only heat the space in use. For ducted systems, opting for zone control improves efficiency by allowing control over the rooms that are heated.
