In this part of Adelaide’s inner east, most homes are two- or three-bedroom places, so hot water demand is steady but not extreme – perfect for a 250–315L heat pump hot water installation or solar hot water installation sized for small to medium families. Many properties still run older gas or resistive electric units, even though hot water energy use can be one of the biggest single loads in the home. Upgrading to an energy efficient hot water system can significantly reduce that share, particularly if you already have rooftop solar.
Typical annual bill savings in St Morris look like this:
• Old electric to heat pump: $400–$800 per year • Gas to heat pump: $300–$700 per year • Gas to solar hot water: $250–$600 per year • Old electric to modern electric with solar: $200–$500 per year
Locally, brands such as Rheem and Rinnai are popular for both electric hot water installation and solar hot water repair, with options like Rheem solar hot water, Rheem heat pump hot water and Rinnai solar hot water widely used. Premium systems like Sanden heat pump units are often chosen by households chasing the best heat pump hot water system and the most efficient hot water system overall, while value-focused buyers might look at Chromagen solar hot water as a cost-effective solar hot water tank replacement.
