That is plenty to support a solar hot water heating system on a good north‑facing roof, and it also helps a heat pump hot water system run efficiently, especially when paired with rooftop solar. Many homes already have solar power, so shifting hot water to a heat pump or solar hot water vs electric hot water on a standard tariff is the next logical step in slashing bills. Annual hot water energy savings can easily reach hundreds of dollars per home when you move away from old gas or resistive electric units.

Across 7321 there are 1,888 occupied private dwellings, and hot water is one of the biggest energy users in each of them.
