In the 5291 area, most dwellings are three‑ and four‑bedroom separate houses, which usually means higher hot water demand – morning showers, dishwashers, laundries and guests. Hot water energy use can easily be a quarter of a home’s electricity bill, so shifting to an energy efficient hot water system delivers real savings. Many households are now weighing up heat pump vs solar hot water and even solar hot water vs electric hot water to find the best fit for their roof space, lifestyle and tariff.
Typical bill savings in Wye look like this:
• Old electric to heat pump hot water system: save roughly $350–$700 per year. • Gas to heat pump hot water system: save around $250–$600 per year. • Gas to solar hot water system: save about $300–$650 per year. • Old electric to modern electric hot water installation with rooftop solar: save about $250–$550 per year.
Brands like Rheem, Rinnai, Sanden and Thermann are common choices locally, with options ranging from rheem solar hot water and rinnai solar hot water through to rheem heat pump hot water and premium sanden heat pump units.
