Hot Water Systems for Central Coast

The Central Coast gets plenty of sunshine, so roof-mounted solar hot water (thermosiphon) is the best fit for most homes—especially those with unshaded, north-facing roof space. It’s simple, proven and highly efficient in our conditions.

If your roof isn’t suitable, there are great alternatives:

Heat pump hot water – Ideal for heavily shaded roofs, apartments/units, or limited roof space. Heat pumps use ambient air to heat water and run on electricity, making them a strong, affordable option where collectors aren’t practical.

Split solar hot water – Good for heritage façades or weight-restricted roofs. Collectors go on the roof while the tank sits at ground level, reducing roof load.

Solahart PowerStore® (PV-ready electric) – Best when you already have rooftop solar panels. It diverts excess solar PV to heat your water, cutting grid use and bills.

Savings vary between home to home, but families can save:
• $600-1000 per year on energy bills
• Up to 90% of water heating costs
• With additional discounts through government rebates (STCs + NSW ESCs).

Even on the sunny Central Coast, your exact savings will depend on current energy costs, household hot water usage, and the exact system type installed. With an average lifespan of 20+ years and rapidly rising electricity prices, the savings from a true solar hot water system are exponential.

Solar hot water works by ‘collecting’ the sun’s heat and transferring this energy to the solar collectors either directly to water or indirectly to anti-freeze fluid, which is used in frost prone areas. The heated water or fluid is then circulated back to the storage tank to provide hot water free from the sun®.

Solar Power (PV panels), on the other hand, rely on sunlight to generate DC electricity, which is fed into an inverter and converted into AC current to power your home.

Although both technologies rely on the sun’s free energy, they have entirely different purposes.

Water heating accounts for around 25% of the average Australian household’s energy use, clearly outweighing other forms of energy consumption.

The great thing about solar water heaters is that they store energy from the sun in a storage tank for later use,
which is in effect, just like a battery. And because they are so efficient, solar water heater collectors take up
about ⅓^ of the roof space needed for an equivalent sized solar power system.

Getting your hot water free from the sun® not only saves energy but also saves greenhouse gas emissions that would have been produced in the generation of that energy. By replacing an electric storage water heater with a Solahart Solar Water Heater, you could reduce greenhouse gas emissions by around 3 tonnes a year*, which is the equivalent of taking a small car off the road.

STCs are part of the government’s commitment to renewable energy. STCs are created when you install and commission qualifying solar hot water, solar/wind power systems or residential solar power systems.

Each STC represents 1 MWh (Megawatt hour) of energy produced. The number of STCs you are eligible for varies
depending on the size of the system you install and your location.

STCs have a market value (which may vary over time) and are tradable; they can be sold, or used to get a discount or cash. Solahart offers an up front discount on the price of a solar power system in return for the STCs.

Of course we service our Solahart products however we also service other brands including Rheem, Dux and Saxon. Get in touch regardless of which brand you have installed and we can help.
