Hot water systems in Mundrabilla
Out on the Nullarbor, a reliable hot water system is not a luxury, it is essential. Around Mundrabilla, WA 6443, more locals are looking at energy efficient options like a heat pump hot water system, solar hot water system and modern electric hot water system to cut running costs and get off ageing gas units. With an average household size of just 1.9 people and a median age of 50, many homes are owned outright and run by long term residents who want low maintenance, dependable hot water without bill shock.
Mundrabilla’s big advantage is sunshine. The local weather station records an impressive 18.2 MJ/m² of solar exposure annually, which works out to roughly 5 kWh of solar energy per square metre per day. That is excellent for both a solar hot water heating system and for powering a heat pump hot water system from rooftop solar. When you combine that with modest median mortgage repayments and a high share of separate houses (252 dwellings), upgrading from old gas or resistive electric to an energy efficient hot water system is a logical next step. Over a year, many Mundrabilla households can save hundreds of dollars in hot water energy use compared to older systems.
For a small postcode, Mundrabilla is already seeing a quiet shift towards efficient hot water. There have been 26 efficient hot water installations (mainly heat pump and solar hot water installations) recorded, with a noticeable peak between 2005 and 2009 when installations climbed to six systems in 2009 alone. While numbers have been flatter since, this early uptake shows strong local interest in lower running costs and more independent, all electric homes. With many residents over 65 and on fixed incomes, the most efficient hot water system you can reasonably afford is often the smartest choice.
Typical annual bill savings for Mundrabilla homes look like this:
• Old electric to heat pump hot water system: $400–$800 per year • Gas to heat pump hot water system: $300–$700 per year • Gas to solar hot water system: $300–$600 per year • Old electric to modern electric hot water installation powered by solar: $250–$500 per year
Brands like Rheem heat pump hot water and Rheem solar hot water are popular for their reliability in remote WA conditions, with options for both roof mounted and ground mounted tanks. Rinnai solar hot water and Chromagen solar hot water units are also common choices where roof space and strong sun make a solar hot water price or cost stack up well over time. For those chasing the best heat pump hot water system on the market, premium units such as Sanden heat pump systems are known for very low running costs, which is ideal where power can be expensive and service visits are a long drive away.
When you are weighing up heat pump vs solar hot water, it often comes down to your roof layout, existing solar, and how you use hot water. A heat pump hot water installation can be very flexible and is often the most efficient hot water system for smaller households, especially when run on timers to soak up daytime solar. A solar hot water installation makes sense if you have clear north facing roof and want to maximise the solar hot water rebate opportunities. Either way, a good installer will talk you through solar hot water vs electric hot water, and even electric hot water vs gas hot water, so you land on the best hot water system Australia can offer for your situation.
There are also options for those who simply need a straight electric hot water installation or hot water repair. A modern, well insulated electric storage unit can still be an energy efficient hot water system when paired with rooftop solar or controlled tariffs. If your old tank is rusting out, a solar hot water tank replacement or upgrade to a heat pump can be timed so you are not left without hot water. Local technicians can handle solar hot water repair, general hot water repair, and full hot water installation, including trusted brands like Rheem, Rinnai and Sanden.
