Millers Forest has solid sunshine, with average solar exposure of about 16.8 MJ/m² per day – roughly 4.7 kWh/m²/day – which is ideal for a solar hot water heating system or supporting a heat pump hot water system on a solar PV array. For many locals, moving from older gas or resistive electric units to the most efficient hot water system they can afford is the logical next step in cutting energy use. Over the life of the unit, annual hot water energy savings can easily add up to thousands of dollars for families and retirees alike.

In this part of NSW, separate houses dominate and many are three‑ and four‑bedroom homes, so hot water demand is steady, especially for families and multi‑generation households. Hot water can be one of the biggest energy users in the home, so choosing the best hot water system Australia has to offer for your needs really matters. Brands like Rheem heat pump hot water and Sanden heat pump systems are popular options for low‑running‑cost upgrades, while Rinnai solar hot water and Chromagen solar hot water are common choices for those who want a roof‑mounted solar hot water installation with a ground or roof tank.

When you compare heat pump vs solar hot water, both can dramatically cut usage compared with older electric hot water vs gas hot water systems. A well‑sized heat pump hot water installation or solar hot water tank replacement can slash the hot water system price you pay over time through lower bills. Typical savings in Millers Forest look like this:

• Old electric to heat pump hot water system: around $350–$700 a year off bills. • Gas to heat pump hot water: roughly $250–$600 a year. • Gas to solar hot water system: often $300–$650 a year. • Old electric to modern electric hot water installation backed by rooftop solar: about $200–$500 a year.

Since 2001 there have been 2,006 efficient hot water installations – mainly heat pump and solar hot water – recorded in the 2324 postcode. Installations peaked around 2009–2011, when more than 800 systems went in over three years, and there has been steady interest ever since, with new systems still being added every year through to 2025. This ongoing pattern shows how households in Millers Forest are gradually electrifying, moving away from gas hot water and chasing lower running costs and emissions.

Hot Water Rebates, Tariffs & Savings

For Millers Forest homeowners, the appeal of replacing an old gas or electric hot water system with an energy efficient hot water system just keeps growing. Federal incentives such as Small‑scale Technology Certificates (STCs) can reduce the effective solar hot water price / cost or heat pump hot water price / cost at the point of sale. On top of that, NSW hot water rebate programs often include a heat pump hot water rebate or solar hot water rebate, and in some cases an electric hot water system rebate when moving away from gas. Together, these hot water rebate NSW schemes can trim the upfront hot water system price / cost by a substantial percentage, turning a five‑to‑seven‑year payback into something much shorter when combined with solar.

With the right set‑up – for example, a Rheem solar hot water or Rinnai solar hot water system on a timer, or a Sanden heat pump controlled to run during the day – you can use your rooftop solar to drive your hot water almost for free. Smart controls and solar diversion can push you closer to the most efficient hot water system for your property and lifestyle, while still allowing for straightforward hot water repair or solar hot water repair if anything goes wrong.
