An average house using gas to heat water produces about 1 tonne of greenhouse gas each year. Using electricity would produce about 4 tonnes.Water heating is the second largest source of household greenhouse gas emissions after transport.Buying an energy-efficient water heater that uses a low greenhouse impact fuel is a great start to greenhouse gas saving.Consider installing a solar hot water system with a booster - gas boosted is best. This will reduce both your hot water bills and greenhouse gas emissions. Gas water heaters carry energy labels to help you choose an efficient model.Avoid gas heaters with continuous pilot lights: save 300 kilograms of greenhouse gas and $55 each year.When selecting a hot water system ensure that its size matches your hot water needs. |
