Cowirra enjoys strong sunshine, with mean daily solar exposure of about 17.5 MJ/m² – roughly 4.9 kWh/m² per day – which is ideal for a solar hot water system or a heat pump hot water system. That solar resource, combined with rising energy prices and modest median household incomes, makes heat pump hot water, solar hot water and efficient electric hot water system options a logical next step from older gas or resistive electric units. Many homes in the district already have rooftop solar, so using a solar hot water heating system or smart electric hot water vs gas hot water is a natural way to turn daytime sunshine into free showers and lower bills.
In a postcode with 1,933 occupied private dwellings and a high proportion of separate houses, hot water demand is steady but predictable, which suits right-sized systems. A three to four person home might look at a 250–315 litre heat pump hot water installation, while couples and retirees are often better off with a smaller, very efficient hot water system to avoid wasting energy. Brands like Rheem heat pump hot water, Sanden heat pump systems and Rinnai solar hot water are common choices for reliable, quiet operation, while Chromagen solar hot water remains popular for roof-mounted solar hot water installation and solar hot water tank replacement when older systems fail.
Typical annual bill savings in Cowirra can look like this:
• Old electric to heat pump: save around $400–$800 per year • Gas to heat pump: save roughly $300–$600 per year • Gas to solar hot water system: save about $250–$550 per year • Old electric to modern electric hot water with rooftop solar: save around $250–$500 per year
