Across Windsor and the wider 5501 area, more households are rethinking their old gas and electric hot water system and moving to smarter, energy efficient options. With around 2,800 occupied dwellings and an average household size of 2.8 people, hot water demand here is solid, especially for busy families and farm households.

Windsor is well suited to efficient hot water. The nearby Wild Horse Plains weather station records an average of about 18 MJ/m² of solar exposure per day – roughly 5 kWh/m² – across the year. That strong sunlight supports both a solar hot water heating system and high‑performance heat pump hot water, particularly when paired with rooftop solar. With a median household income of about $1,708 a week and many homes owned with a mortgage, upgrading from older gas or off‑peak electric units to the most efficient hot water system is a logical way to cut running costs and free up cash. Annual hot water energy savings can easily reach hundreds of dollars for Windsor homeowners switching from ageing systems.
In the 5501 postcode, separate houses dominate, which typically means larger hot water cylinders and higher usage. For a typical Windsor family, hot water can account for 20–30% of total household energy use, so choosing the best hot water system Australia has to offer for your needs really matters. Many locals are now comparing heat pump vs solar hot water, and even solar hot water vs electric hot water, to see what stacks up best with their roof space, budget and tariffs.
Typical annual bill savings for Windsor homes can look like this:
• Old electric to heat pump hot water installation: save roughly $400–$800 per year. • Gas to heat pump hot water system: save around $300–$700 per year. • Gas to solar hot water installation: save about $300–$600 per year. • Old electric to modern electric hot water installation with rooftop solar: save about $250–$500 per year.

Hot Water Rebates, Tariffs & Savings
More Windsor households are now weighing up electric hot water vs gas hot water and asking whether a solar hot water price / cost or heat pump hot water price / cost makes sense after rebates. Australian Federal Government incentives, like Small‑scale Technology Certificates (STCs), help bring down the upfront solar hot water cost and heat pump hot water cost. On top of that, South Australian hot water rebate SA programs can offer a solar hot water rebate, heat pump hot water rebate or electric hot water system rebate for eligible homes, especially when replacing old electric or gas units. These hot water rebate SA incentives can effectively cut the installed system cost by a substantial percentage and shorten payback times, particularly if you use timers or solar diversion so your electric hot water system runs mainly on your own rooftop solar.
