Heat Pumps


Heat pump water heaters use electricity to move heat from one place to another instead of generating heat directly. Therefore, they can be two to three times more energy efficient than conventional electric resistance water heaters. To move the heat, heat pumps work like a refrigerator in reverse. While a refrigerator pulls heat from inside a box and dumps it into the surrounding room, a stand-alone air-source heat pump water heater pulls heat from the surrounding air and dumps it — at a higher temperature — into a tank to heat water. 


Heat pumps are one of the most energy-efficient hot water solutions. While they need electricity to run, they are said to be roughly three times more efficient than traditional electric water heaters.

Other advantages are: No panels on roof required and do not require sunlight to operate. Help reduce your carbon footprint and greenhouse gas emissions. Most heat pumps water heaters utilise the same plumbing as electric hot water so perfect to retrofit.


Like solar water heaters, heat pump water heaters cost more to purchase than conventional HWS but save energy and can reduce energy bills. Small-scale technology certificates (STCs) are available from the Australian Government to assist with their purchase cost.

Seek expert advice from Sharpe Services on choosing the most cost-effective heat pump and electricity tariff for your local climate and needs.

Did you know?

Heat pumps use FREE natural energy from the air to create hot water by transferring the heat in the air to the water stored inside. It moves heat rather than generates it, and that is where the cost savings lie.


Solar Hot Water


Solar hot water systems are storage units which generate heat from the sun using panels installed on the roof of the property. This heat is used to warm and maintain the water in your tank. When there is insufficient solar generation, systems can be boosted to a temperature of 60°C by either electric or natural gas boosters. Solar water systems can be split-system or combined.


Solar hot water systems could reduce your hot water system’s energy consumption significantly, although the potential savings are disputed and naturally subject to your personal circumstances, including where you live. Solar hot water systems are generally considered as the most environmentally friendly option. Accredited solar systems might also be eligible for STC rebates from the Federal Government.


Solar hot water systems have the greatest upfront costs after rebates, depending on the system size and excluding any installation costs. Some solar hot water systems may also be unreliable on overcast days, but most models will kick-over to natural gas or electric back-up heating if the water isn’t hot enough.

Gas Hot Water


Storage gas water systems use a gas burner to continuously heat and maintain water in a tank at 60°C. Continuous flow systems also use a burner which ignites only when the water is needed.


Gas hot water systems will produce few greenhouse gas emissions. Additionally, depending on your location, gas systems are usually considered to have lower usage rates compared to electricity, making them a more cost-effective option long term.


Gas hot water systems are only really viable if you’re connected to mains gas, as using LPG bottles is more expensive, and creates the risk of running out of hot water. Gas hot water systems must be located outside or have an exhaust vent if they are located inside.

Electric Hot Water


Standard electric storage water heaters use a heating element inside the tank to heat the water, just like an electric kettle. However, when powered using mainland grid power in Australia, they are responsible for the most greenhouse gases of any water heater and are being phased out for household use. Their emissions can be greatly reduced by using Greenpower or other renewable energy to run the water heater.


Electric hot water systems usually have relatively low upfront costs and can be a reliable way to keep your water warm. Most large electric storage hot water systems are connected to controlled load tariffs and do most of their heating at off-peak periods to help reduce your energy bills.


Electrical hot water systems are almost always the most expensive long-term hot water solution if used on a continuous day rate tariff. The electricity that powers them may also have high greenhouse gas emissions if the power does not come from renewable sources such as solar PV, wind, or from a hydro scheme.
