Hot water systems in Lower Light
Across Lower Light and the wider 5501 area, more households are shifting from old gas and electric units to an energy efficient hot water system. With an average household size of about 2.8 people and more than 2,800 dwellings, reliable hot water is a daily essential – and so are manageable power bills. Many homes are owned with a mortgage, so every saving on running costs helps free up cash for other priorities.
Lower Light is blessed with strong sunshine, averaging around 17.9 MJ/m² of solar exposure a day over the year – roughly 5 kWh/m² per day. That is ideal for both a solar hot water system and a heat pump hot water system, because there is plenty of free energy in the air and on your roof to do the heavy lifting. Upgrading from an older gas or resistive electric hot water system to a modern heat pump, solar hot water heating system or efficient electric hot water system can trim hundreds of dollars a year from bills, especially for busy families and larger homes.
In a postcode where most dwellings are three or four bedrooms, hot water demand is steady, and hot water energy use can quietly make up a big slice of overall household energy. That is why more locals are comparing heat pump vs solar hot water and even looking at solar hot water vs electric hot water to find the most efficient hot water system for their situation. Brands like Rheem heat pump hot water, Sanden heat pump and Rinnai solar hot water are popular options, along with systems from Thermann and other reputable suppliers. Many households still choose a straightforward electric hot water installation, pairing it with rooftop solar and smart timers to run when solar is producing.
Typical average annual bill savings in Lower Light look like this:
• Upgrading old electric to a heat pump hot water system: $400–$800 per year • Switching gas to heat pump hot water: $300–$700 per year • Switching gas to a solar hot water system: $250–$600 per year • Upgrading old electric to a modern electric hot water system run on solar: $250–$500 per year
Since the early 2000s there have been 421 efficient hot water installations (heat pump and solar hot water installation jobs) recorded in the 5501 area. Install numbers peaked between about 2003 and 2010, when annual installs were often in the 30–40 range, and there is now a steady trickle of new systems each year as older units fail or energy prices rise. This pattern shows growing local interest in electrification, lower running costs and using Lower Light’s strong solar resource. As systems age, demand for hot water repair, solar hot water repair and solar hot water tank replacement is also increasing, and many residents are choosing to replace like-for-like gas or electric with a more energy efficient hot water system instead.
Hot Water Rebates, Tariffs & Savings
For Lower Light homeowners, the numbers stack up even better once rebates are added. The Federal Government’s Small-scale Technology Certificates (STCs) effectively act as an upfront discount on eligible solar hot water systems and heat pump hot water installation, cutting the solar hot water price / cost or heat pump hot water price / cost by a substantial percentage. On top of that, South Australian schemes often provide a heat pump hot water rebate or solar hot water rebate, and there can be an electric hot water system rebate when replacing inefficient models. Together, these hot water rebate SA programs can bring the hot water system price / cost down to something much more affordable, often shaving years off the payback period.
For many Lower Light homes, moving to the best heat pump hot water system they can reasonably afford, or a quality rheem solar hot water, rinnai solar hot water or chromagen solar hot water setup, can mean saving hundreds of dollars a year while cutting emissions. Using timers or solar diversion to run an electric hot water system during the middle of the day makes even more sense where rooftop solar is common. With the right design, hot water SA households can enjoy some of the most efficient hot water system options available in Australia.
