Summerhill is well suited to efficient hot water upgrades. Local solar exposure at nearby Mount Leslie averages about 14.9 MJ/m² a day, which is roughly 4.1 kWh/m² of sunshine to drive a solar hot water heating system or support a heat pump hot water system. Many homes already have rooftop solar, so a modern electric hot water system on a timer, or a dedicated solar hot water system, can soak up excess daytime generation instead of sending it back to the grid for a low feed in rate. With a median household income of about $1,400 a week and plenty of homes still paying mortgages or rent, cutting running costs without sacrificing comfort makes real sense.
In 7250 there is a healthy mix of separate houses and townhouses, plus more than 2,000 flats and apartments. That means there is no single "best hot water system Australia" wide for everyone – the right choice depends on roof space, access, tariffs and hot water demand. For many Summerhill homes, a heat pump hot water system is now the most efficient hot water system option, using ambient air to heat water and slashing electricity use compared with an old electric hot water system. Others prefer a roof mounted solar hot water installation with a ground or roof tank, especially where there is clear northern roof space.
Local installers are seeing steady interest in brands such as Rheem heat pump hot water units, Rheem solar hot water systems and Chromagen solar hot water solutions, alongside premium options like a Sanden heat pump for households chasing ultra low running costs. Rinnai solar hot water is also common where owners want a trusted name and good backup service. Whether you are comparing heat pump vs solar hot water or weighing up solar hot water vs electric hot water, a tailored design makes all the difference.
In the 7250 postcode there have already been 699 efficient hot water installations, including both heat pump and solar hot water systems.

• Replacing an old electric hot water system with a quality heat pump hot water system: about $350–$700 per year. • Switching from gas hot water to a heat pump hot water system: roughly $250–$600 per year. • Moving from gas to a well designed solar hot water system: around $200–$500 per year. • Upgrading an old electric unit to a modern electric hot water installation controlled by timers and powered by rooftop solar: often $200–$450 per year.
Well known brands like Rheem solar hot water, Rinnai solar hot water and Chromagen solar hot water are common choices for a solar hot water tank replacement where the old cylinder has failed. For compact blocks or shaded roofs, a Sanden heat pump or other best heat pump hot water system options can deliver similar savings without needing large collector panels. Thoughtful system sizing based on your family’s usage pattern helps keep the hot water system price or cost under control while still meeting demand for showers, laundry and dishes.
When you are comparing heat pump hot water price or cost and solar hot water price or cost, remember to factor in rebates. Summerhill homeowners can usually tap into Federal Small scale Technology Certificates (STCs) for eligible solar hot water and heat pump systems, plus Tasmanian energy efficiency programs that operate as a hot water rebate tas. These can act like an instant discount at the point of sale, cutting the upfront hot water system price by a substantial percentage. On top of that, a heat pump hot water rebate or solar hot water rebate may apply during certain schemes, and there are times when an electric hot water system rebate is available for replacing old, inefficient units.
With lower running costs, it is common for an efficient hot water upgrade to save hundreds of dollars a year on bills, particularly when paired with solar. That means payback periods can shrink to just a few years, especially if you use timers or solar diversion controls to heat water in the middle of the day. Over the life of the system, those savings can easily add up to several thousand dollars, all while reducing emissions and improving comfort.
Of course, even the best systems need looking after. If you have an older unit, keeping up with hot water repair and servicing helps avoid cold showers and surprise failures. Local specialists can handle solar hot water repair, valve replacements, element changes and full solar hot water tank replacement when the time comes. The same goes for heat pump hot water repair and maintenance – a quick check‑up can keep performance high and energy use low.
