Many local families are paying off a mortgage of about $1,500 a month and juggling everyday expenses, so shifting to a modern solar hot water system, heat pump hot water system or efficient electric hot water system is a logical next step.
Mulgundawa is well suited to efficient hot water upgrades. The area enjoys strong sunshine, with average solar exposure of about 17.2 MJ/m² per day – roughly 4.8 kWh/m² of usable energy – which is ideal for both a solar hot water heating system and for helping a heat pump hot water system run efficiently. With a median household income of around $1,364 a week and a good mix of owned‑outright and mortgaged homes, many residents are looking to cut bills and future‑proof their properties. Upgrading from older gas or resistive electric units can trim hot water energy use dramatically; it is common for Mulgundawa homeowners to save hundreds of dollars a year in hot water energy alone.
In the 5255 postcode, hot water demand is driven by mostly three‑bedroom family homes, with a sizeable number of retirees and over‑65s who value comfort and low maintenance. Hot water can easily account for a quarter of a home’s total electricity use, so choosing the most efficient hot water system really matters. Brands like Rheem solar hot water, Rinnai solar hot water, Sanden heat pump and Thermann are popular options locally, offering everything from compact heat pump hot water installation through to larger roof‑mounted solar hot water installation with ground tanks. For some properties, a modern electric hot water installation paired with rooftop solar can still be the most efficient and affordable choice.
Typical annual bill savings in Mulgundawa look like this:
• Old electric to quality heat pump: $400–$800 per year • Gas storage to heat pump: $300–$600 per year • Gas storage to solar hot water system: $250–$550 per year • Old electric to new electric hot water system with good solar: $200–$450 per year
Local data shows 471 efficient hot water systems have already been installed in the 5255 area, combining heat pump and solar hot water installation. Uptake spiked around 2003–2010, with peak years such as 2009 seeing over 60 installs, and there has been steady ongoing interest through to 2025. This long‑term trend reflects a clear shift towards electrification, lower running costs and more sustainable hot water SA‑wide, with Mulgundawa households keen to move away from gas and explore options like heat pump vs solar hot water and solar hot water vs electric hot water.
Hot Water Rebates, Tariffs & Savings
For Mulgundawa homeowners, hot water rebate SA programs and federal incentives can make upgrading far more affordable. The Australian Government’s Small‑scale Technology Certificates (STCs) effectively act as an upfront discount on eligible solar hot water systems and heat pump hot water systems, cutting the solar hot water price / cost or heat pump hot water price / cost by a substantial percentage. South Australian schemes often provide a specific heat pump hot water rebate or solar hot water rebate, and there can be an electric hot water system rebate for certain efficient models when replacing gas.
When you stack these rebates with smart tariffs and rooftop solar, payback periods can shorten to just a few years. Many Mulgundawa homes are using timers or solar‑diversion controllers so their hot water system heats mainly during sunny hours, turning a standard unit into a truly energy efficient hot water system. For some, that means choosing the best heat pump hot water system they can afford; for others it is a robust rheem heat pump hot water or sanden heat pump paired with existing PV, or a chromagen solar hot water or rinnai solar hot water setup with a well‑sized solar hot water tank replacement. Either way, the long‑term solar hot water price / cost or heat pump hot water cost is often far lower than sticking with gas.
If your current unit is leaking, older than 10 years or struggling to keep up, it is a good time to compare electric hot water vs gas hot water and heat pump vs solar hot water for your home.
