Hot water systems in Erub Island
On Erub Island, more homeowners are looking for a hot water system that keeps showers comfortable without sending power bills through the roof. With a young community, an average household size of 3.3 people and many larger family homes, hot water demand is high. At the same time, median household income is modest, so switching from old gas or tired electric hot water to an energy efficient hot water system is a smart way to free up cash for other priorities.
Erub Island’s tropical location is ideal for a solar hot water system or heat pump hot water system. The nearby Albany Island weather station records around 20.6 MJ/m² of sunshine a day on average – roughly 5.7 kWh/m² – which is excellent for both a solar hot water heating system and high‑efficiency heat pumps. With most dwellings being separate houses and a big share of rented homes, there is real potential for landlords and families to upgrade from basic electric hot water vs gas hot water units to modern, efficient options and lock in long‑term savings. Annual hot water energy savings can easily reach hundreds of dollars per home when older systems are replaced.
Across the 4875 postcode, hot water energy use is a big slice of overall household electricity, especially where older resistive electric units run on standard tariffs. For a typical Erub Island family, the most efficient hot water system will usually be either a quality heat pump hot water system or a well‑designed solar hot water system backed up by efficient electric boosting. Brands such as Rheem heat pump hot water, Sanden heat pump and Rinnai solar hot water are popular choices nationally, and systems like Rheem solar hot water or Chromagen solar hot water are often used where reliability in remote conditions matters.
Average annual bill savings from a hot water upgrade on Erub Island can look like:
• Old electric to heat pump hot water installation: $400–$800 per year • Gas to heat pump vs solar hot water: typically $300–$700 per year • Gas to solar hot water installation: $300–$600 per year • Old electric to modern electric hot water installation with rooftop solar: $250–$500 per year
In total, around 137 efficient hot water systems have already been installed in the 4875 area, mainly heat pump and solar hot water installation projects. There was a strong burst of activity between 2007 and 2011, with 45 installs in 2007 and 27 in 2008, and more recent upgrades in 2014 and 2018. These hot water installation figures show a clear local interest in electrification, lower running costs and stepping away from expensive gas or ageing cylinders. As older units reach the end of their life, demand for solar hot water tank replacement, solar hot water repair and hot water repair in general is likely to keep growing.
Even in a remote community like Erub Island, there is rising awareness of hot water rebate QLD programs and the benefits of moving to efficient systems. Federal incentives such as Small‑scale Technology Certificates (STCs) reduce the solar hot water price / cost and heat pump hot water price / cost by providing an upfront discount based on system size and performance. QLD hot water rebate schemes and electric hot water system rebate offers can further cut the effective hot water system price / cost, sometimes trimming 20–40% off the installed cost. When you combine these rebates with rooftop solar and smart timers or solar‑diversion controls, payback periods on a best heat pump hot water system or quality solar hot water vs electric hot water upgrade can drop to just a few years, while ongoing savings of several hundred dollars a year are realistic.
