When you are comparing heat pump vs solar hot water, it is worth looking at both upfront hot water system price and long‑term savings. A quality heat pump hot water price might be higher than a basic electric hot water system cost, but it can use around 70% less electricity. Likewise, a solar hot water price can be offset by generous rebates and the free energy from the sun. Here are some typical bill savings Keilor Park households might see:
• Old electric to heat pump hot water system: $350–$700 a year • Gas storage to heat pump hot water system: $250–$600 a year • Gas storage to solar hot water system: $200–$550 a year • Old electric to modern electric hot water installation with solar PV: $250–$500 a year
On top of lower bills, many residents are also planning for hot water VIC tariffs and a future all‑electric home powered by rooftop solar. When you factor in a solar hot water rebate, a heat pump hot water rebate and, in some cases, an electric hot water system rebate, the effective heat pump hot water cost or solar hot water price can drop sharply. Federal Small‑scale Technology Certificates (STCs) reduce the upfront cost of eligible systems, and Victorian hot water rebate VIC programmes can offer additional discounts on approved heat pump and solar units. For many Keilor Park households, these incentives can cut the system cost by a substantial percentage and shorten payback to just a few years, especially when combined with timers or solar‑diversion controls that heat water when your panels are producing.
