Brands like Rheem and Rinnai are common choices for the best hot water system Australia can offer in remote and coastal conditions, with options spanning rheem solar hot water, rheem heat pump hot water and rinnai solar hot water. Premium heat pump options such as Sanden heat pump units are also popular where households want the most efficient hot water system possible.
In the 4875 postcode, there have already been 137 efficient hot water systems installed, combining both heat pumps and solar hot water installation jobs. Installations peaked around 2007 and 2008, when dozens of systems went in each year, with solid activity again in 2014 and a smaller wave from 2017 to 2018. This steady history of heat pump hot water installation and solar hot water repair work shows growing local interest in electrification, lower running costs and more resilient, energy efficient hot water system options that suit island life.
When it comes to system sizes and savings, most Stephens Island homes will be looking at a 250–315 litre electric hot water installation or a similar‑sized heat pump or solar hot water tank replacement for families of three to five people. With so many separate houses and multi‑bedroom dwellings, hot water demand is steady year‑round. Choosing between heat pump vs solar hot water or solar hot water vs electric hot water will depend on roof space, budget, and whether you already have rooftop solar.
Typical hot water system price or hot water system cost will vary with brand and size, but energy savings are where the real value lies. To give you a feel for it, here are some indicative annual bill savings for Stephens Island households:
• Old electric to heat pump hot water system: save around $400–$800 per year. • Gas to heat pump hot water: save roughly $300–$600 per year. • Gas to solar hot water system: save about $250–$600 per year. • Old electric to modern electric hot water with solar PV: save around $300–$700 per year.
Heat pump hot water price or cost can be higher upfront than a basic electric hot water system, but rebates and lower running costs usually mean a shorter payback period. For some households, the best heat pump hot water system might be a premium Sanden heat pump; others might prefer a robust rheem heat pump hot water unit or a chromagen solar hot water setup that pairs neatly with rooftop PV. In all cases, the aim is to create an energy efficient hot water system that keeps showers hot while keeping bills manageable.
