Hot water systems in Forest Hill
Across Forest Hill and the 4342 area, more locals are rethinking their old gas and electric hot water system and switching to energy‑efficient options. With most of the 947 dwellings being separate houses and an average household size of 2.6 people, hot water demand is steady – and so are the bills if you stay on outdated technology.

Forest Hill’s sunshine is a big advantage. The local weather station records an average annual solar exposure of about 18.7 MJ/m² per day – roughly 5.2 kWh/m² of solar energy hitting your roof daily. That strong sunlight helps a solar hot water system or heat pump hot water system run efficiently, slashing running costs compared with older electric hot water vs gas hot water setups. For many homes, upgrading to an energy efficient hot water system can deliver substantial annual hot water energy savings without sacrificing comfort.
In a family‑oriented community, with 696 families and plenty of three‑ and four‑bedroom homes, a correctly sized hot water system is important. A modern heat pump hot water system or solar hot water heating system can cover typical household demand while using a fraction of the energy. Brands like Rheem heat pump hot water, Sanden heat pump and Rinnai solar hot water are common choices for Forest Hill homeowners wanting the most efficient hot water system they can reasonably afford. For those preferring a simpler option, a quality electric hot water system from a trusted brand can still work well, especially when paired with rooftop solar.
Locally, there have been 142 efficient hot water installations (heat pump and solar) recorded in the postcode, showing growing confidence in these technologies. Installations peaked around 2004 and 2009–2010, with a new wave of interest from 2023 onwards, including 10 installs in 2024 alone. That recent lift reflects a broader push towards electrification, lower running costs and reduced emissions in Forest Hill QLD, as people compare heat pump vs solar hot water and look for the best hot water system Australia has to offer for their budget.
Typical annual bill savings for Forest Hill homes can look like this:
• Old electric to heat pump hot water installation: save roughly $350–$700 per year. • Gas to heat pump hot water installation: save around $250–$600 per year. • Gas to solar hot water installation: save about $250–$650 per year. • Old electric to modern electric hot water installation with solar: save roughly $200–$500 per year.
When you factor in hot water system price / cost, these savings can quickly add up. A heat pump hot water price / cost is usually higher upfront than a basic electric hot water installation, but the running costs are dramatically lower. Similarly, a solar hot water price / cost is higher at the start, yet the ongoing bills can be minimal, especially with a good solar hot water tank replacement and smart controls.
