There are two main types of electric water heaters:
For those considering the merits of a gas electric water heater, there are two main types:
Gas systems rapidly heat water, making them ideal for larger households with higher consumption. However, they result in more greenhouse gas emissions than electric options.
Our experienced plumbers are ready to help you select the best option.
Heat pumps are more energy efficient than traditional electric hot water system options. They work by extracting latent heat from ambient air and using this to heat your water.
Unlike a traditional storage water heater that uses heating elements, heat pumps leverage the renewable thermal energy in the surrounding air. An integrated compressor and evaporator takes heat from the air, pressurising refrigerant which gets hot. This thermal energy gets transferred via a heat exchanger into the water.
Although more costly initially, the superior efficiency of heat pump units can lead to reduced running costs, offsetting the initial expense over time. Efficiently designed systems can significantly reduce energy bills by achieving over 300% efficiency, producing more energy than consumed.
Their efficiency also depends on factors like climate and international performance standards vary.
Modern heat pumps are designed to perform well in various climates, ensuring you get a system with an excellent energy rating. Look for well-known brands meeting Australian MEPS standards for optimal efficiency. We advise on heat pump systems that provide the best long-term value, tailored to your household’s needs.
When compared, gas electric water heaters and standalone electric models have their merits with moderate operating costs.
Storage tank systems are more affordable initially but take longer to heat and have limited capacity. Storage tanks consist of an insulated tank where water is stored and maintained at a consistent temperature, ready for use.
Tankless electric water heaters provide hot water on demand, eliminating the need for storage capacity. Gas tankless systems have higher flow rates than electric water options and boast lower operating costs.
The tankless system is applicable to both electric and gas configurations. Tankless water heaters provide unlimited hot water but can be an expensive purchase initially.
Gas electric hot water systems are suitable for households with low to medium hot water demand. Electric gas tankless options work better for larger families with high peak demands. For ultimate efficiency, we suggest gas tankless units but will align the system with your specific context, opting for electric if a gas line isn’t present.
Get in touch with Kareela Plumbing to identify the water heater that aligns with your financial plan, hot water demand, and home setup.
When analysing efficiency and operating costs, gas hot water systems generally come out ahead of electric. Studies show gas systems are around 30-45% more energy efficient than electric on average.
This begs the question of how much you might save with gas systems - with approximate operating cost savings of $100-150 per year compared to electric. However, actual costs ultimately depend on local energy prices, household usage patterns and the age/specs of your existing system.
While gas systems edge out electric overall, heat pump technology can match or even exceed gas efficiency in certain applications. Properly sized heat pumps require less electricity due to their use of ambient thermal energy.
Consider long-term savings against initial costs when aiming to save money over time. Newer systems may cost more upfront but deliver better efficiency and faster payback which can be beneficial in the long term. Our team of plumbers can install and provide tailored advice for your home.
When installing hot water systems, electric and gas units have some differing requirements to consider.

When considering the lifespan of gas vs electric hot water systems, gas units generally last longer with a lifespan between 10-15 years on average.
Electric storage type water units typically last 8-12 years, while electric heat pumps can function effectively for 15+ years if properly maintained. The compressor of a heat pump system will likely need replacing at the 10-12 year mark at a cost of $1000+.
Natural gas LPG systems need new burners and seals replacing every 5 years or so at a lower cost. Anode rods and valves also need periodic replacement. We offer discounted parts and can source most common spares required for maintenance and repairs.
Ultimately regular servicing is key to maximising lifespan for both electric and gas systems. Kareela Plumbing’s annual maintenance plans help optimise functionality and longevity. For part replacements or repairs, feel free to reach out at any time.
Selecting the appropriately sized hot water system is essential to meet demand efficiently without squandering energy and funds on surplus heating. Consider factors for your hot water system like:
Gas systems require existing lines, whereas heat pumps and electric storage tanks need only an appropriate power outlet. We assess your unique requirements during site inspections to select the right types water heaters for your home.
Kareela Plumbing offers free household water audits. We evaluate your property’s water setup, measure flow rates and pressures, and suggest optimally sized systems considering demand.
When it comes to environmental impact, electric hot water systems are generally seen as the greener, more eco-friendly option compared to gas systems.
Gas systems emit higher levels of greenhouse gases like carbon dioxide and nitrogen oxides from burning fossil fuels. The carbon footprint of gas hot water units is estimated to be nearly double that of a solar hot water system or electric heat pump.
Electric systems can also take advantage of renewable energy from the grid to heat water only when necessary, with zero emissions, acting as an energy saver. Utilising solar water heating solutions, such as solar-powered heat pumps or electric systems augmented by rooftop solar panels, have very low carbon footprints.
Analysing the spectrum of hot water vs environmental concerns, gas does heat water faster and often has a lower operational cost, but eco-conscious households may prefer electric options. Electric water heater technology, especially heat pumps, also offers gas-rivalling efficiency without the air pollution.
Making small changes like switching to which hot water system is energy efficient like an electric one can reduce your environmental impact over time. Kareela Plumbing expertly installs electric and solar hot water solutions for an eco-friendly home.
There are several ways homeowners can enhance efficiency to save on hot water system operating costs:
Modest upgrades in water systems can lead to substantial savings, curbing both unnecessary heating and reducing energy use and emissions. Contact Kareela Plumbing to assess efficiency improvements tailored for your property.
When deciding between electric and gas hot water systems in Kareela, weigh up the efficiency, operating costs, environmental impact and installation requirements against your household’s unique hot water needs.
Gas systems heat water faster and can supply larger homes with ease but produce more greenhouse emissions compared to an electric water heater. Modern hot water heaters offer more advanced features, like those with heat pump technology, which can match straight gas efficiency without the large carbon footprint—especially when solar-assisted.
Carefully consider the number of occupants, bathing habits, laundry loads, dishwasher use and simultaneous water draw. This helps size the right system to meet demands without wasting money and energy heating excess water.
While gas heaters are generally cheaper to run long-term, electricity prices and new rebates make heat pumps very affordable. Installation is simpler and less expensive to install than gas systems, as they don’t require a gas line, making electric models easier and cheaper to set up.
