Hot Water Systems in Mortlake

Hot water systems in Mortlake

Across Mortlake and the 2137 postcode, more households are rethinking their old gas and electric hot water and moving to energy efficient options. With an average household size of 2.6 people and more than 10,000 dwellings, reliable hot water is non‑negotiable – but so are rising power prices. For many Mortlake homeowners and businesses, upgrading to a modern heat pump hot water system, solar hot water system or efficient electric hot water system is the logical next step to cut bills and future‑proof their property.

Mortlake’s climate is well suited to efficient hot water. The local solar exposure at Concord averages about 16.2 MJ/m² per day – roughly 4.5 kWh/m² of sunshine – which supports strong performance from both a solar hot water heating system and a quality heat pump hot water system. With a healthy mix of separate houses (around 4,484) and more than 4,600 flats and apartments, there is demand for compact, quiet systems that still deliver strong savings. Many families here have solid incomes (median total household income sits around $2,377 per week), so shifting from electric hot water vs gas hot water to the most efficient hot water system is often about comfort, running costs and lowering emissions rather than just getting the cheapest unit.

In Mortlake 2137, hot water energy use can be a big slice of the household bill, especially in all‑electric homes. That is why we are seeing more interest in heat pump vs solar hot water comparisons, solar hot water vs electric hot water options, and the best hot water system Australia can offer for medium‑density living. Brands like Rheem heat pump hot water and Sanden heat pump units are popular where ultra‑low running costs matter, while Rheem solar hot water, Rinnai solar hot water and Chromagen solar hot water systems are common on townhouses and larger homes with good roof space. For many, a modern electric hot water installation paired with rooftop solar can still be a very energy efficient hot water system.

Typical annual bill savings in Mortlake for a well‑designed hot water installation can look like:

• Old electric to heat pump hot water installation: save around $400–$900 per year. • Gas to heat pump hot water system: save roughly $300–$700 per year. • Gas to solar hot water installation: save about $250–$600 per year. • Old electric to new electric hot water installation with solar: save around $250–$500 per year.

Local data shows this shift is already under way. In the 2137 area, there have been 180 efficient hot water systems installed – a mix of heat pump and solar hot water installations. Install numbers ramped up in the late 2000s, peaking around 2008–2009, and while yearly figures have steadied since, there is still a consistent trickle of new systems each year through to 2025. That pattern reflects growing long‑term interest in electrification, lower running costs and smarter hot water NSW‑wide, especially among Mortlake owners who have already invested in rooftop solar.

Hot Water Rebates, Tariffs & Savings

For Mortlake households, the appeal of replacing old gas or electric units with a heat pump hot water system, a modern electric hot water system or a solar hot water system is boosted by generous incentives. The Federal Government’s Small‑scale Technology Certificates (STCs) apply to eligible solar hot water heating system and heat pump installs, effectively acting as an upfront discount on the hot water system price. On top of that, NSW hot water rebate programmes can provide a specific heat pump hot water rebate or solar hot water rebate for qualifying homes, while some schemes also support efficient electric hot water system rebate options when moving away from gas.

When you combine STCs with state incentives, it is common for the heat pump hot water price or solar hot water price to be reduced by a substantial percentage. That brings premium options like Sanden heat pump systems or the best heat pump hot water system from brands such as Rheem into reach for more Mortlake families. With typical savings of hundreds of dollars per year, payback periods can shrink to just a few years, especially if you use timers or solar diversion to run your hot water system when your rooftop solar is producing. For many, that makes an energy efficient hot water system one of the quickest upgrades to pay for itself.

If your current unit is older, unreliable or you are facing a solar hot water tank replacement or hot water repair, it is a good time to review the full hot water system cost rather than just patching the old one. Experienced local installers can guide you through hot water repair vs replacement, explain electric hot water vs gas hot water running costs, and help you choose between heat pump vs solar hot water based on your roof, tariffs and household size.
