Resumen del manual
Example: For an energy consumption of 21,500 MJ per year and a natural gas tariff of 2.1 cents per MJ ($0.021/MJ), the lifetime running cost is: 21,500 x $0.021 x 12 = $5,418 The labels can also be used to estimate the lifetime greenhouse gas emissions. For each MJ of gas consumed, around 0.06 kg of carbon dioxide is emitted, so for the example above the greenhouse gas emissions are: 21,500 x 0.06 x 12 = 15,480 kg or 15.48 tonnes The actual running costs and greenhouse gas emissions will depend on where you live, your gas type and tariff, cold water temperatures, the amount of hot water used, the quality of installation, the thermostat setting and user behaviour. Call the Sustainable Energy Development Office Energy Smart Line on 1300 658 158 if you need help estimating running costs. If you would like details on models on the market, contact the appliance supplier or your local gas appliance retailer. If you want more information on choosing a gas water heater to suit your needs, contact the Sustainable Energy Development Office Energy Smart Line on 1300 658 158. If you want more information on gas Energy Rating labels, contact the Australian Gas Association’s Technical Office on: Telephone (03) 9580 4500 For more information on Top Energy Saver Award Winner winning appliances log onto the Top Energy Saver Award Winner web site: Based on a usage of 200 litres of hot water per day, 2.1c/MJ tariff $0 $2,000 $4,000 $6,000 Typical 12-year running costs for water heaters 5 star model 3 star model Top Energy Saver Award Energy saving winners features An easy way to make sure you choose the most energy efficient gas water heater is to ask for Australia’s star energy performers—Top Energy Saver Award Winner (TESAW) winners. Each year, a government authority presents TESAW to gas water heaters that have the highest star ratings. Choosing a TESAW of gas water heater could have a big impact on household energy costs. For a typical four-person household, the savings could be as much as $984 over a 12-year lifetime. This would also reduce greenhouse gas emissions by some 3.1 tonnes. Look for the TESAW logo on appliances, and in brochures and catalogues. For more information on Award winning appliances log onto the Top Energy Saver Award Winner web site: Look for these features before you buy: . A size or capacity that matches your hot water needs—this is expressed in litres for storage systems and litres per minute for continuous flow systems . Avoid models with a pilot light if considering a continuous flow system . Adjustable thermostats for temperature control. These allow you to reduce the temperature of the hot water, saving energy . Remote water temperature controls . Consider a gas-boosted solar hot water system. These do not carry gas Energy Rating labels. Gas-boosted solar water heating may be an option if you have a suitable area of north facing roof which is unshaded throughout the year. While they cost more to buy, the typical payback period from the energy savings could be as little as 5 years (for new homes). Government rebates are available in Western Australia. The rebate will reduce the overall installation costs and therefore also reduce the payback period. For further information on rebates, visit the web site at: ...
