Swapping from older gas or resistive electric to a modern heat pump or solar hot water system can deliver substantial Annual Hot Water Energy Savings for Margaret River homeowners.
Across the 6285 postcode, families make up a big share of the community, which means strong morning and evening hot water demand. A 3–4 bedroom home with two bathrooms will typically be well matched to a 250–315L heat pump hot water installation or a similar‑sized solar hot water tank replacement. Efficient hot water can easily account for a third of household energy use in older homes, so cutting that load has a big impact on bills.
Typical annual bill savings in Margaret River look like:
• Old electric to heat pump hot water system: $400–$900 per year • Gas storage to heat pump: $300–$700 per year • Gas storage to solar hot water system: $250–$650 per year • Old electric to new electric hot water installation powered by rooftop solar: $250–$600 per year
Brands like Rheem heat pump hot water and Rheem solar hot water are popular for robust, well‑supported systems, while Rinnai solar hot water and Sanden heat pump units are often chosen for high efficiency and low running costs. Many locals also compare heat pump vs solar hot water to decide which will be the most efficient hot water system for their roof space, budget and household routine. For some, solar hot water vs electric hot water (with PV) is the key question; for others, it is simply finding the best heat pump hot water system that works quietly and reliably through cooler winters.
Efficient hot water is not new to the area. In fact, around 1,130 efficient hot water systems – mainly heat pump and solar hot water installations – have already gone in across the 6285 postcode. Installations climbed steadily from the early 2000s, with strong years around 2005–2010, and have continued at a consistent rate through to 2024 and 2025. This steady trend shows growing interest in electrification, lower running costs and cleaner hot water in Margaret River, as more households choose to move away from gas and older electric units and invest in an energy efficient hot water system.
Hot Water Rebates, Tariffs & Savings
Right now, there is strong interest in replacing ageing gas and electric units with efficient options like heat pumps, upgraded electric hot water systems or a rooftop solar hot water heating system in Margaret River. Homeowners can often tap into Australian Government incentives in the form of Small‑scale Technology Certificates (STCs), which effectively discount the solar hot water price or heat pump hot water price at the point of sale. On top of this, WA‑based schemes and retailer offers may provide a heat pump hot water rebate, solar hot water rebate or electric hot water system rebate, helping to bring the overall hot water system cost down.
When you combine these hot water rebate WA incentives with smart tariffs and rooftop solar, the upfront cost of a quality Rheem solar hot water, Rinnai solar hot water, Sanden heat pump or similar system can be reduced by a substantial percentage. Many households see hundreds of dollars a year shaved off their bills, with payback periods shortened further by using timers or solar diversion to run a heat pump during the middle of the day. For all‑electric homes aiming to cut emissions as well as costs, solar hot water vs electric hot water on a standard tariff is an easy win, while electric hot water vs gas hot water increasingly favours efficient electric options.
If your existing unit is more than 10 years old, running out of hot water or needing regular hot water repair, it is a good time to check whether your Margaret River home is ready for a hot water upgrade.
