This trend reflects a growing interest in electrification, lower running costs and moving away from gas hot water. As systems age, more households are looking at heat pump vs solar hot water, solar hot water vs electric hot water, and even solar hot water tank replacement to stay ahead of rising tariffs.
Typical upgrade savings in a sunny coastal climate like Low Isles are impressive. As a rough guide, bill reductions might look like this:
• Old electric to heat pump hot water system: about $350–$650 per year • Gas to heat pump hot water system: about $250–$500 per year • Gas to solar hot water system: about $200–$450 per year • Old electric to modern electric hot water with good solar: about $200–$400 per year
When you factor in the hot water system price and ongoing savings, many locals are finding the payback surprisingly quick. A quality heat pump hot water price or solar hot water price can be higher upfront than a basic tank, but the running costs are dramatically lower.
