Heat Pump Mechanics
Heat-pump hot water systems harness the principles of refrigeration cycles to extract heat from the surrounding air. This heat is then transferred to water within an insulated storage cylinder through a heat exchanger. The energy efficiency of these systems is impressive, consuming approximately 60 to 75% less electricity compared to conventional electric hot water systems. Unlike the direct heating mechanism employed by traditional electric systems, heat pumps employ electricity to power the heat pump itself, which then heats the water indirectly.
Sun-Powered Efficiency: A Kinship with Solar Heaters
An interesting analogy emerges when considering heat-pump hot water systems and solar water heaters. Both systems harness the sun’s energy, albeit in different ways. Heat-pump systems derive heat from the air, which is ultimately warmed by the sun. Unlike solar systems, heat pumps don’t rely on electric or gas boosters, utilizing electricity solely for operating the evaporator fan and compressor during water heating. This distinction positions heat-pump systems as efficient alternatives to solar heaters.

Brandon LiWe had our gas hot water system changed by Geoff last month. From start to finish, he was an absolute pleasure to deal with. Initial call was full of information to allow us to do all the research we needed and no pushy sales tactic, just a caring approach to solve your issue which is what we really appreciated. Extremely organised, he even installed a mini temp heater to get us through the week! Installation was brilliant, really well priced and went out of his way to help us with everything and more. Couldn't recommend Geoff and his son Trent enough. Extremely clean, methodical work - everyone we have shown have been extremely impressed with the work done - let the pictures speak for themselves! A BIG thank you to Janey behind the scenes for making things happen with our rebate too!! We have already started recommending Geoff to people we know on the peninsula for when they need their hot water system fixed/changed/updated! We will be a lifelong customer. Thank you again & speak soon. BrandonPosted on Google

Clean Energy Regulator – STCs
STC Rebate
STC’s are a Federal Government rebate. The good news about this rebate is that if you install a heat pump hot water you will qualify for a rebate amount, that is only dependent on which brand and model you install.
STC’s are used as a way to meet renewable energy targets and reduce carbon emissions. They make renewable energy systems more accessible and attractive.
When you install an eligible renewable energy system, you earn a certain number of STCs.
Â
Â
The average amount of this rebate is approximately $800.
Victorian Energy Upgrades
VEEC Rebate
The Victorian Energy Upgrades (VEU) program offers incentives for households to upgrade to efficient hot water systems. Only products meeting the VEU program requirements can be installed under this program. This is commonly called the VEEC rebate.
VEEC rebate amounts vary depending if the system you are replacing is common storage electric or gas. Existing solar hot water systems now qualify subject to conditions*.
amount of this rebate is approximately $675 when replacing storage electric and $450 when replacing gas hot water.
*To be eligible for VEEC’s, the solar system must be at least 5 years old and must have non-functioning components.
