That level of solar energy is ideal for a solar hot water heating system or a high‑performance heat pump hot water system that sips electricity while pulling most of its heat from the air. For many homes, hot water can be one of the biggest single users of energy, so the annual hot water energy savings from an upgrade can be substantial over the life of the system.
Around 3,765 occupied private dwellings in the postcode means a lot of bathrooms, laundries and kitchens needing dependable hot water. Many of these are three‑ and four‑bedroom separate houses, so hot water demand is steady, especially for working families on median household incomes of about $1,429 per week. When you compare the hot water system price or cost of keeping an old gas or electric unit running to the long‑term savings from an energy efficient hot water system, the numbers start to favour upgrading.
In Merungle Hill, you will see familiar brands like Rheem and Rinnai in both traditional and efficient models, as well as premium options such as Sanden heat pump systems and Chromagen solar hot water setups. Locals often ask about heat pump vs solar hot water, or solar hot water vs electric hot water. The right choice depends on roof space, budget, whether you already have solar panels, and when your household uses the most hot water. Many homes pair a rheem heat pump hot water or sanden heat pump unit with rooftop solar to create one of the most efficient hot water system combinations available. Others prefer a rheem solar hot water or rinnai solar hot water system with a solar hot water tank replacement to make the most of our sunshine.
To give you an idea of savings, here are typical average annual bill reductions when you combine smart hot water installation with the right tariff and, where possible, solar power:
• Old electric to heat pump hot water system: save roughly $400–$800 per year. • Gas to heat pump hot water system: save around $300–$600 per year. • Gas to solar hot water system: save about $250–$550 per year. • Old electric to modern electric hot water installation with solar: save roughly $250–$500 per year.
Over time, those savings help offset the heat pump hot water price or cost, or the solar hot water price or cost, especially when you factor in rebates.
