In a postcode with around 7,600 occupied dwellings and an average household size of 2.6 people, hot water demand is steady all year round, so getting the most efficient hot water system you can makes real financial sense.
Locally we enjoy strong sunshine, with average solar exposure of about 17.4 MJ/m² per day – roughly 4.8 kWh/m² of solar energy. That makes Howick well suited to a solar hot water system or a heat pump hot water system that can sip power while still keeping a family-sized tank hot. With more than 5,300 owner-occupied homes (owned outright or with a mortgage), plenty of households are in a good position to upgrade from old gas or electric units to an energy efficient hot water system and lock in long-term savings. Swapping a tired gas or electric storage unit for a modern system can cut annual hot water energy use dramatically, often saving hundreds of dollars a year.
In the 2330 postcode, efficient hot water systems have already made their mark, with 1,261 heat pump and solar hot water installations recorded. Installations ramped up sharply from 2009 to 2011, when households first jumped on rebates, and while numbers have steadied since, recent years still show a solid trickle of heat pump hot water installation and solar hot water installation as systems reach end-of-life and people upgrade. Brands like Rheem heat pump hot water and Rheem solar hot water are popular for reliable, well-known performance, while Sanden heat pump units are often chosen for ultra-efficient, whisper-quiet operation. Rinnai solar hot water and Chromagen solar hot water are also common options when homeowners want a robust solar hot water heating system with a proven track record.
For many homes in Howick, hot water energy use is one of the biggest single loads after heating and cooling. That is why comparing heat pump vs solar hot water, and even solar hot water vs electric hot water, is worth the effort. A modern electric hot water system paired with rooftop solar and a timer can be surprisingly cheap to run, while a quality heat pump can be the most efficient hot water system for shaded sites. When you are weighing up hot water system price or cost, it is smart to look beyond the sticker price and factor in running costs over 10–15 years, plus any hot water repair history on your existing unit.
Typical annual bill savings in a Howick home might look like:
• Old electric to heat pump hot water system: $350–$700 per year • Gas storage to heat pump hot water: $250–$600 per year • Gas storage to solar hot water system: $200–$550 per year • Old electric to modern electric hot water system with solar: $200–$500 per year
Well-known brands such as Rheem, Rinnai, Sanden and Thermann all offer options that can qualify as the best hot water system Australia for different households, depending on budget, space and hot water demand.
