Hot water systems in Rosedale
Across Rosedale, more locals are swapping old gas and ageing electric units for modern, energy efficient hot water systems. With most of our 857 dwellings being separate houses and an average household size of 2.4 people, a reliable hot water system is essential – but so is keeping running costs under control. Many households are on a median total household income of around $1,302 a week, so upgrading to a smarter hot water system that slashes bills is a logical next step.
Rosedale’s strong sunshine also helps. The local weather station records an average annual solar exposure of about 15.2 MJ/m² a day – roughly 4.2 kWh/m² – which is excellent for both a solar hot water system and a heat pump hot water system. That solar resource means a well-designed solar hot water heating system or high quality heat pump can cover most of a family’s hot water needs, especially for three and four bedroom homes that make up the bulk of the area.
We are already seeing the shift. There have been 160 efficient hot water installations – mainly heat pump and solar hot water – across postcode 3847. Installations jumped from just a couple in the early 2000s to peaks around 2009–2010, with steady activity every year since. Recent years, including 2022 and 2023, have held up well, reflecting growing interest in electrification, lower running costs and getting ready for more rooftop solar in Rosedale VIC.
For many homes, hot water is one of the biggest energy users, so moving from old gas or an inefficient electric hot water system to a modern heat pump hot water system or solar hot water system can deliver serious savings. Typical annual bill savings in Rosedale look like this:
• Old electric to quality heat pump: around $350–$700 a year • Gas storage to heat pump: around $250–$600 a year • Gas to solar hot water: around $200–$550 a year • Old electric to modern electric with solar: around $200–$500 a year
Brands like Rheem heat pump hot water and Rheem solar hot water are popular for their reliability, while Rinnai solar hot water and Sanden heat pump options are often chosen by households chasing the most efficient hot water system on the market. Many locals researching the best hot water system Australia offers are weighing up heat pump vs solar hot water and even solar hot water vs electric hot water, looking for the best heat pump hot water system or a robust chromagen solar hot water style setup that will last.
In Rosedale, hot water installation decisions often come down to hot water system price, ongoing running cost and roof orientation. A heat pump hot water installation can work brilliantly even on shaded blocks, using ambient air instead of direct sun, while a solar hot water installation suits homes with good north-facing roof space. Some households opt for a modern electric hot water installation paired with solar PV and a timer, making it a very energy efficient hot water system in practice. When older systems fail, solar hot water tank replacement or a switch to heat pump is a smart way to future-proof.
Hot Water Rebates, Tariffs & Savings
With so many homes in Rosedale owned outright or with a mortgage, there is strong interest in using rebates to upgrade from gas to an efficient hot water system. Homeowners can usually tap into Australian Government Small-scale Technology Certificates (STCs) for eligible heat pump and solar hot water systems, plus state-based heat pump hot water rebate and solar hot water rebate programs that apply in hot water vic. There are also schemes that support an electric hot water system rebate when shifting away from gas.
These hot water rebate vic incentives can cut the upfront heat pump hot water price or solar hot water price by a substantial amount, sometimes by 30–50% once STCs and state discounts are applied. That brings the effective hot water system cost right down and can shorten payback to just a few years, especially if you use timers or solar diversion to run your electric hot water vs gas hot water mostly on cheap solar. Over the life of the unit, that can mean thousands saved compared with an old gas or resistive electric system.
If your current unit is more than 10 years old, running out of hot water, or your bills seem too high, it is a good time to check whether your Rosedale home is ready for a hot water upgrade. Whether you are considering heat pump hot water, a solar hot water repair and upgrade, or a new electric hot water system, working with experienced hot water installers like us makes the process simple.
