In Mermaid Beach 4218, hot water energy use is a significant slice of the household bill, particularly in smaller apartments where hot water can be one of the biggest single loads. That’s why efficient hot water installation is on the rise. Typical annual bill savings can look like this:
• Replacing an old electric hot water system with a heat pump hot water system: save around $350–$700 per year. • Switching from gas hot water to a heat pump hot water system: save about $250–$600 per year. • Moving from gas to a solar hot water system: save roughly $250–$550 per year. • Upgrading an old electric hot water system to a modern electric hot water installation paired with rooftop solar: save about $300–$650 per year.
Over time, these savings easily outweigh the hot water system price / cost, especially when you factor in a heat pump hot water rebate, solar hot water rebate or electric hot water system rebate where available. For many homes, the most efficient hot water system will be either a quality heat pump (often the best heat pump hot water system for smaller blocks and units) or a well-sized solar hot water vs electric hot water upgrade on a sunny roof. Comparing heat pump vs solar hot water comes down to roof space, shading, budget and whether you already have solar PV. Our local installers can also advise on solar hot water vs electric hot water for specific Mermaid Beach properties.
