Waterloo is actually well suited to efficient hot water technology. Nearby Beaufort records an average annual solar exposure of about 15.7 MJ/m² per day, which works out to roughly 4.4 kWh/m² of sunshine daily. That’s plenty to drive a solar hot water heating system or help a heat pump run efficiently, especially if you already have rooftop solar.

In the 3373 postcode there are more than a thousand occupied private dwellings, most with three or four bedrooms, so hot water demand is steady even as the median age sits in the early fifties. For many of these homes, hot water energy use is one of the biggest single loads on the power bill. Swapping an old electric hot water system or gas unit for an energy efficient hot water system can trim a big chunk from annual running costs. Brands like Rheem, Rinnai, Sanden and Thermann are common choices locally, whether that’s a rheem solar hot water package on the roof, a rheem heat pump hot water unit in the side yard, a rinnai solar hot water system, a sanden heat pump for maximum efficiency, or a straightforward Thermann electric hot water installation.
