Hot water systems in The Keppels
In The Keppels, hot water is not something you want to think about until the shower runs cold or the power bill lands. With energy prices rising, more locals are looking at an energy efficient hot water system – whether that is a modern electric hot water system, a solar hot water system or a heat pump hot water system – to keep costs down without sacrificing comfort.
The Keppels and the wider 4700 area have a lot going for them when it comes to efficient hot water. The region enjoys strong sunshine, with mean daily solar exposure of about 19.5 MJ/m² – roughly 5.4 kWh/m² per day – which is ideal for a solar hot water heating system or a high‑performance heat pump hot water system. With around 6,601 occupied private dwellings, an average household size of 2.3 people and a big mix of separate houses and flats, there is steady demand for reliable hot water installation, hot water repair and sensible running costs across families, retirees and renters alike.
Many homes in The Keppels are still running older gas or resistive electric units. Swapping to the most efficient hot water system you can reasonably afford is a logical next step in cutting bills and emissions. For a typical 4700 household, upgrading to an energy efficient hot water system can trim a big slice off annual energy use, especially when hot water makes up a large share of total consumption.
Across the 4700 postcode, 1,443 efficient hot water systems – mainly heat pumps and solar hot water systems – have already been installed. Installations climbed steadily through the 2000s, peaking around 2010, then picked up again from 2020 to 2021 as interest in electrification and lower running costs surged. Even with a small drop in 2022–2024, these numbers show growing confidence in options like heat pump hot water installation and solar hot water installation as locals move away from gas hot water.
For a typical The Keppels home, the choice often comes down to heat pump vs solar hot water, or solar hot water vs electric hot water. Quality brands such as Rheem, Rinnai, Sanden and Thermann are common in the local market, with options that cover everything from a compact electric hot water installation in a unit through to a large rheem solar hot water or rinnai solar hot water system on a family home. Premium systems like a Sanden heat pump or Rheem heat pump hot water unit can offer some of the best heat pump hot water system efficiencies available, while chromagen solar hot water and other solar brands remain popular where roof space and aspect are favourable.
Average annual bill savings will vary, but realistic ranges for The Keppels households look like:
• Old electric to heat pump hot water system: $450–$900 per year • Gas hot water to heat pump: $300–$700 per year • Gas hot water to solar hot water system: $250–$650 per year • Old electric to modern electric hot water system with rooftop solar: $250–$600 per year
When you factor in hot water system price, it is worth weighing not just the upfront cost but also the long‑term savings. A quality heat pump hot water price or solar hot water price can look higher at first, but lower running costs often deliver a solid payback, especially in a sunny, coastal climate like The Keppels.
