Hot water systems in Streatham
Across Streatham and the wider 3351 area, more households are quietly moving away from old gas and power‑hungry electric units and upgrading to an energy efficient hot water system. With most homes here being separate houses and an average household size of about 2.7 people, long showers, farm mud and kids’ baths all add up – so hot water energy use can be a big slice of the power bill.
Streatham’s climate is actually well suited to efficient hot water. Nearby Wongan records an average annual solar exposure of around 15.6 MJ/m² per day – roughly 4.3 kWh of sunshine a day – which is great for both a solar hot water system and a modern heat pump hot water system. With many households on a mortgage and median household income sitting around $1,684 a week, cutting running costs without sacrificing comfort is a pretty logical next step. Switching from older gas or an ageing electric hot water system to efficient technology can deliver solid annual hot water energy savings for Streatham homeowners.
In the 3351 postcode there are more than 3,000 dwellings, many with three or four bedrooms, so hot water demand is steady year‑round. That is driving interest in options like a solar hot water heating system on the roof, a high‑efficiency heat pump hot water system in the yard, or a well‑sized electric hot water system paired with rooftop solar. Brands such as Rheem heat pump hot water units, Sanden heat pump systems and Rinnai solar hot water setups are common choices for those chasing the most efficient hot water system. For others, Rheem solar hot water or Chromagen solar hot water can be a practical way to use the sun for everyday showers.
Typical savings in Streatham will vary by home, but a hot water upgrade can make a real dent in bills:
• Old electric to heat pump hot water installation: save roughly $350–$700 per year. • Gas to heat pump: save about $250–$600 per year. • Gas to solar hot water installation: save around $200–$500 per year. • Old electric to modern electric hot water installation with rooftop solar: save roughly $250–$550 per year.
Local data shows 664 efficient hot water systems have already been installed in the 3351 area, combining heat pump and solar hot water installation projects. Uptake really took off around 2008–2011, when installations jumped from single digits to peaks of 58 in 2008 and 88 in 2009. More recently, there has been steady interest, with 40–51 systems going in each year from 2019 to 2023. This trend reflects growing awareness of electrification, lower running costs and the appeal of an energy efficient hot water system as power prices rise.
Hot Water Rebates, Tariffs & Savings
For Streatham households comparing heat pump vs solar hot water or even solar hot water vs electric hot water, rebates are a big part of the story. Australian Government Small‑scale Technology Certificates (STCs) apply to eligible solar hot water systems and many heat pump units, effectively acting as an upfront discount off the solar hot water price / cost or heat pump hot water price / cost. On top of that, Victorian hot water rebate programs can support heat pump hot water installation and sometimes solar hot water tank replacement, and there may be an electric hot water system rebate for efficient all‑electric upgrades.
When you combine STCs with state heat pump hot water rebate offers and a good tariff, the overall hot water system price / cost can be cut by a substantial percentage. That means payback periods for the best heat pump hot water system or a quality rheem solar hot water setup can shrink to just a few years, especially if you use timers or solar‑diversion to run the system when your PV is generating. For many homes, that translates into hundreds of dollars off annual bills, plus the comfort of a reliable, energy efficient hot water system.
If you are weighing up electric hot water vs gas hot water, or trying to choose between heat pump vs solar hot water for your place in Streatham VIC, it is worth looking closely at both running costs and rebates. A well‑designed solar hot water repair or hot water installation – whether that is heat pump, solar or modern electric – can reduce bills, cut emissions and future‑proof your home as more households shift to all‑electric living.
If your existing unit is older, noisy or needing regular hot water repair, now is a good time to check whether your Streatham home is ready for a hot water upgrade.
