The nearby Highlands weather station records an average annual solar exposure of about 17.3 MJ/m² per day – roughly 4.8 kWh/m² of sunshine daily. That strong solar resource supports both a solar hot water heating system and modern heat pump hot water, especially when paired with rooftop solar. For households on fixed incomes or with a median household income of around $1,087 per week, shifting from old gas or resistive electric hot water to technology that slashes energy use can mean sizeable annual hot water energy savings.
Across postcode 3727, there have been 11 efficient hot water installations recorded, including both solar hot water installation and heat pump hot water installation. The busiest years were 2008, 2009 and 2014, with two systems each, and another system going in as recently as 2024. That steady trickle of installs shows growing local interest in electrification and lower running costs. As more Lake Rowan homes add solar, it makes sense to look at solar hot water vs electric hot water, or heat pump vs solar hot water, to see which option fits your roof space, budget and hot water demand.
For a typical Lake Rowan family, hot water can be one of the biggest energy users in the house. Swapping an old electric hot water system for the best heat pump hot water system you can afford can cut energy use by up to two‑thirds. Brands like Rheem heat pump hot water, Sanden heat pump and EvoHeat are popular choices, while Rheem solar hot water, Rinnai solar hot water and Chromagen solar hot water are common for roof‑mounted or split‑system solar hot water tank replacement. Many locals still prefer a straightforward electric hot water installation, especially when it can be timed to run on solar during the day.
Typical savings in a town like Lake Rowan look like this:
• Old electric to heat pump: around $350–$700 a year off bills. • Gas to heat pump: roughly $250–$600 a year saved. • Gas to solar hot water: often $200–$500 a year. • Old electric to new electric with solar: about $200–$450 a year.
These ranges will vary with household size, tariffs and how efficiently the system is set up, but they give a feel for the potential hot water system price / cost payback.
