In a suburb where separate houses are still common alongside townhouses and apartments, we see everything from compact electric hot water installation jobs in units through to full solar hot water heating system upgrades on larger family roofs. Swapping an old gas or electric hot water system for an energy efficient hot water system can deliver substantial annual hot water energy savings for Bardwell Valley homeowners.
In 2207, hot water demand is driven by busy family homes as well as a sizeable older population, so reliability matters just as much as efficiency. Many properties still use gas, but the trend is shifting towards all‑electric homes, with people comparing electric hot water vs gas hot water and weighing up heat pump vs solar hot water. Modern options include a straightforward electric hot water system, a high‑efficiency heat pump hot water system, or a roof‑mounted solar hot water system with a well‑insulated solar hot water tank replacement. Brands like Rheem solar hot water, Rinnai solar hot water, Sanden heat pump and EvoHeat are common choices when locals ask for the best hot water system Australia has to offer or the best heat pump hot water system for their situation.
Typical hot water system price and running costs vary, but the savings can be impressive. A heat pump hot water price may be higher upfront than a basic electric unit, yet the most efficient hot water system options can cut energy use by 60–75%. To give a sense of what Bardwell Valley households might save each year on bills:
• Old electric to heat pump hot water system: $400–$800 • Gas to heat pump hot water system: $300–$600 • Gas to solar hot water system: $300–$700 • Old electric to modern electric hot water system with solar: $250–$500
Over time, these upgrades help reduce overall hot water system cost, especially when paired with rooftop solar. Many locals also ask about solar hot water vs electric hot water and solar hot water vs electric hot water with solar diversion; with Bardwell Valley’s good sun, both can work well when properly sized.
