Bunyip’s solar exposure is a real strength. The nearby Garfield weather station records an average of about 14.4 MJ/m² of sunshine each day, which is roughly 4 kWh/m² per day. That level of sun is ideal for a solar hot water heating system or a high‑quality heat pump hot water system that uses ambient air. Swapping out an older gas or electric unit can deliver solid Annual Hot Water Energy Savings for Bunyip homeowners, especially with rising energy prices and median household incomes carefully balanced against mortgages and everyday costs.
Across the 3815 postcode, most dwellings have three or four bedrooms, so hot water demand is steady, particularly for families with kids and older relatives under one roof. Hot water can easily make up a quarter of a home’s energy use, so choosing the most efficient hot water system has a big impact. Local homes are increasingly pairing rooftop solar with a heat pump hot water installation or solar hot water installation to soak up surplus solar and reduce grid reliance.
In Bunyip, typical annual bill savings from an upgrade can look like this:
• Old electric to heat pump hot water system: around $400–$800 per year • Gas to heat pump: around $300–$600 per year • Gas to solar hot water system: around $250–$600 per year • Old electric to modern electric hot water installation with solar: around $200–$500 per year
Brands like Rheem, Rinnai, Sanden and Thermann are common in the local market, offering options from rheem solar hot water and rheem heat pump hot water through to rinnai solar hot water and premium sanden heat pump units. Many households ask which is the best hot water system Australia can offer for their situation, or the best heat pump hot water system for a growing family. Others are weighing up heat pump vs solar hot water, or comparing solar hot water vs electric hot water and electric hot water vs gas hot water for running costs, reliability and noise. For some, a chromagen solar hot water or similar system may suit roof space and budget; for others, a quiet heat pump on an off‑peak tariff is the winner.
Recent installs in Bunyip show how quickly things are changing. There have been 296 efficient hot water systems installed in the 3815 postcode, combining heat pump and solar hot water installations. Install numbers were modest in the early 2000s, then picked up sharply from around 2009, with a peak of 46 installations in 2019 and consistently strong years through 2020 and 2021. While 2022–2024 show fewer installs, the total still reflects strong local interest in electrification, lower running costs and using Bunyip’s sunshine to power hot water.
Hot Water Rebates, Tariffs & Savings
Right now, many Bunyip households are looking to replace old gas or resistive electric units with efficient options such as a heat pump hot water system, a newer electric hot water system or a solar hot water heating system. Federal incentives like Small‑scale Technology Certificates (STCs) apply to eligible systems, effectively acting as an upfront solar hot water rebate or heat pump hot water rebate that can trim the heat pump hot water price or solar hot water price by a substantial percentage. Victoria also offers additional state‑based support, including heat pump and electric hot water system rebate schemes that further reduce the hot water system price or cost for homeowners in hot water vic. With these hot water rebate vic programs, it is common to see payback periods drop to just a few years, especially when you run the unit on a smart tariff, add timers, or use solar diversion so your hot water system soaks up excess rooftop solar. Over time, the typical savings can reach hundreds of dollars per year off bills from an energy efficient hot water system, and a well‑timed solar hot water tank replacement or hot water repair can be an opportunity to upgrade rather than just patch an old unit.
If you are in Bunyip and wondering whether to stick with gas, choose electric, or go all‑in on solar, it is worth getting tailored advice. A local specialist can walk you through hot water installation options, electric hot water installation, solar hot water repair and hot water repair for existing systems, and help you decide between solar hot water vs electric hot water or heat pump vs solar hot water for your roof, budget and family size.
