Across 2251, most dwellings are separate houses, with plenty of roof space for a solar hot water installation or PV‑powered electric hot water installation, and enough side access for a compact heat pump hot water installation. Hot water typically makes up around a quarter of household energy use, so switching to the most efficient hot water system you can reasonably afford has a big impact on bills. Many locals are weighing up heat pump vs solar hot water, or solar hot water vs electric hot water, and looking closely at total hot water system price, running cost and payback rather than just the sticker.
