Typical hot water system price or cost will vary by size and technology, but the savings can be substantial. As a rough guide for Ernestina homes:
• Old electric to heat pump: save about $350–$700 per year on bills. • Gas to heat pump: save roughly $250–$600 per year. • Gas to solar hot water: save around $300–$650 per year. • Old electric to modern electric hot water installation with rooftop solar: save $250–$500 per year.
When you compare heat pump vs solar hot water, both can be the most efficient hot water system for Ernestina, depending on roof space, budget and when you use hot water. A solar hot water vs electric hot water decision often comes down to whether you already have rooftop PV and if you want to use timers or solar diversion to run an electric hot water system when the sun is shining. If your roof tank is ageing, a solar hot water tank replacement paired with your existing panels can be a smart middle ground. For some households, the best heat pump hot water system will beat solar on flexibility, especially where roof space is tight.
