Hot water systems in Mount Barker
In Mount Barker, hot water is a big chunk of the power bill, so more locals are moving from old gas and electric units to an energy efficient hot water system. With most homes here being separate houses and an average household size of around 2.4 people, there is steady hot water demand, from busy families to older couples. At the same time, power prices keep climbing while many households are on fixed incomes, with a median household income of about $1,191 a week. That makes upgrading to a modern hot water system a practical way to cut running costs without changing your lifestyle.
Mount Barker is well suited to both heat pump hot water and solar hot water. The area enjoys strong sunshine, with average annual solar exposure of about 16.5 MJ/m² per day – roughly 4.6 kWh/m²/day – which is ideal for a solar hot water system or a solar hot water heating system backed up by an efficient electric hot water system. When you factor in the number of owner‑occupied homes, especially those owned outright, it makes sense that many residents are looking at long‑term savings and lower maintenance options instead of patching up an ageing gas unit.
Across the 6324 postcode, there are 1,358 occupied private dwellings, many with three or four bedrooms, so a correctly sized hot water installation is important. Hot water use can easily be a quarter of household energy, so choosing the most efficient hot water system you can afford has a big impact on bills. Brands like Rheem, Rinnai, Sanden and Chromagen are common in Western Australia, offering options from rheem solar hot water and rheem heat pump hot water through to rinnai solar hot water and chromagen solar hot water systems. For many homes, the best hot water system Australia can offer will be either a quality heat pump hot water system or a well‑designed solar hot water installation with electric backup.
Average annual bill savings in Mount Barker for typical upgrades can look like this:
• Old electric hot water system to a heat pump hot water system: $400–$800 per year • Gas hot water to heat pump hot water: $300–$700 per year • Gas hot water to solar hot water system: $300–$700 per year • Old electric hot water to modern electric hot water installation with rooftop solar: $250–$600 per year
Over time, those savings can easily outweigh the hot water system price, especially when you include a solar hot water rebate, heat pump hot water rebate or electric hot water system rebate that may apply in WA.
In Mount Barker, around 300 efficient hot water systems – mainly heat pumps and solar hot water – have already been installed, and the yearly numbers show how interest has grown. Installations picked up through the 2000s, with strong years around 2008–2011, and while the pace has varied since, there are still new systems going in every year, including in 2024 and 2025. This steady uptake reflects a clear shift towards electrification, more energy efficient hot water system choices and lower running costs, as homeowners weigh up heat pump vs solar hot water and even solar hot water vs electric hot water with rooftop PV.
Hot Water Rebates, Tariffs & Savings
More Mount Barker households are now replacing old gas or resistive electric hot water with options like heat pump hot water installation, solar hot water installation or efficient electric hot water installation.
