In a typical Sebastian home, hot water can be one of the biggest single energy loads, so choosing the most efficient hot water system you can afford is a smart move. Whether you are comparing heat pump vs solar hot water, looking at solar hot water vs electric hot water, or weighing up electric hot water vs gas hot water, the right choice depends on your roof space, tariffs and household usage.
Sebastian and surrounding areas have already seen strong uptake of efficient systems, with 1,192 heat pump and solar hot water installations recorded. Installations were modest in the early 2000s, then jumped sharply around 2009 and 2012, and have stayed solid through to 2024, reflecting growing interest in electrification and lower running costs.
