When you compare heat pump vs solar hot water, both can be the most efficient hot water system for different homes. A solar hot water vs electric hot water decision will depend on your roof space, budget and how much sun your property gets. In some cases, the best hot water system Australia‑wide for small households might be a compact electric hot water system with a good timer and solar diversion; for larger families, a chromagen solar hot water or rheem solar hot water setup with a generous solar hot water tank replacement can make more sense.
