Many Colbrook homes already have rooftop solar, so pairing that with an energy efficient hot water system – whether a chromagen solar hot water unit, rheem solar hot water, rinnai solar hot water or a top‑tier sanden heat pump – can be one of the easiest ways to lift solar self‑consumption and cut bills. For some, the best hot water system Australia has to offer will be a premium heat pump; for others, a well‑sized solar hot water heating system or a simple, well‑timed electric hot water installation will be the right fit.
