The nearby Morrl Morrl weather station records an impressive 16.9 MJ/m² of average annual solar exposure – roughly 4.7 kWh of solar energy per square metre each day. That strong sunlight supports both a solar hot water heating system on the roof and a high performance heat pump hot water system in the yard, delivering solid annual hot water energy savings for households making the switch.
Across the 3381 postcode there are 777 dwellings, with around 490 occupied. Many still rely on older gas or resistive electric units that chew through power. In a typical home, hot water can account for a quarter of total energy use, so choosing an energy efficient hot water system has a big impact. Over time, the hot water system price / cost to run matters more than the upfront tag, which is why so many people are comparing heat pump vs solar hot water and even solar hot water vs electric hot water when planning their next upgrade.
For a small community, Callawadda has seen strong interest in efficient systems, with 102 heat pump and solar hot water installations recorded so far. Installations spiked around 2008–2010 when rebates were generous and have continued at a steady pace through to 2025, showing ongoing interest in electrification, lower bills and cutting emissions. Brands like Rheem heat pump hot water and Sanden heat pump units are popular for rural properties chasing the best heat pump hot water system performance, while Rheem solar hot water, Rinnai solar hot water and Chromagen solar hot water are common choices for a reliable solar hot water installation and long lasting solar hot water tank replacement.
When you look at hot water system price / cost over the life of the unit, the savings add up quickly. Typical bill reductions in Callawadda might look like this:
• Old electric to heat pump hot water installation: save roughly $350–$700 per year • Gas to heat pump hot water system: save around $250–$600 per year • Gas to solar hot water system: save about $200–$500 per year • Old electric to modern electric hot water installation with rooftop solar: save roughly $200–$450 per year
Those savings are helped along by government incentives. Federal Small-scale Technology Certificates (STCs) apply to eligible solar hot water systems and heat pump hot water systems, effectively acting as an upfront solar hot water rebate or heat pump hot water rebate. In Victoria, extra state programs can further cut the heat pump hot water price / cost or solar hot water price / cost for owner occupiers and some rentals. There are also schemes that support an electric hot water system rebate when replacing gas, helping more homes move to all-electric living. For Callawadda households, these hot water rebate vic programs can knock a substantial percentage off the installed cost, shortening the payback period to just a few years, especially if you run your unit on a solar-friendly tariff or use timers and solar diversion.
If your current unit is leaking, unreliable or more than 10–15 years old, it may be time to look at hot water repair versus full replacement. In many cases, upgrading from electric hot water vs gas hot water to a new energy efficient hot water system delivers better value than ongoing hot water repair bills. Local installers can talk you through options such as Rheem solar hot water, Rinnai solar hot water, Sanden heat pump or a quality Chromagen solar hot water setup, and help you compare solar hot water vs electric hot water based on your roof space, budget and household size.
