Swapping an older gas or electric hot water system for a heat pump or solar hot water heating system can deliver substantial annual hot water energy savings for Riverstone homeowners.
With so many separate houses and growing families, demand for reliable hot water is constant. A typical Riverstone hot water installation might be a 250–315L heat pump hot water system for a family of four, or a roof‑mounted solar hot water installation matched to existing rooftop solar. Brands like Rheem solar hot water, Rinnai solar hot water, Sanden heat pump and Thermann heat pump options are all popular, giving you a choice of some of the best hot water system Australia has to offer. For many homes, the most efficient hot water system will be either a quality heat pump or a solar hot water vs electric hot water upgrade that uses cheap daytime solar.

If you prefer simplicity, a modern electric hot water system with a smart timer, running mostly on rooftop solar, can still be one of the best heat pump hot water system alternatives for smaller households. Either way, a quality electric hot water installation, solar hot water tank replacement or hot water repair done properly will keep showers hot and bills low.
