Hot Water Systems in Merrijig

Hot water systems in Merrijig

In Merrijig, more locals are rethinking their old gas and electric hot water systems and moving to energy efficient options like a heat pump hot water system, solar hot water system and modern electric hot water system. With many homes owned outright or with a mortgage, and an average household size of around 2.2 people, it makes sense for Merrijig households to lock in lower running costs and more reliable hot water. Upgrading to an efficient hot water system is one of the simplest ways to cut bills without changing how you live.

Merrijig’s climate helps too. The nearby Bald Hill weather station records an average annual solar exposure of about 15.7 MJ/m² a day, which is roughly 4.4 kWh/m² of sunshine. That is strong support for a solar hot water heating system or a high quality heat pump hot water system, both of which can turn free renewable energy into hot showers. With many families and older residents on fixed incomes, and a median household income that rewards careful budgeting, switching from older gas or resistive electric hot water to a more efficient hot water installation is a logical next step.

Across postcode 3723, there are 1,218 occupied private dwellings, most of them separate houses with three or four bedrooms. That means decent hot water demand for showers, washing and cleaning, especially in winter. A significant share of these homes still use gas or older cylinders, even as efficient options grow. When you look at heat pump vs solar hot water, both can dramatically reduce the share of hot water energy use in your overall household energy bill, especially if you already have rooftop solar.

Typical annual bill savings in Merrijig look like this:

• Replacing an old electric hot water system with a heat pump hot water system: save around $350–$700 per year. • Switching from gas hot water to a heat pump: save roughly $250–$600 per year. • Switching from gas to a solar hot water system: save about $250–$550 per year. • Upgrading an old electric hot water system to a modern electric hot water installation timed to run on solar: save around $200–$450 per year.

Local homes are choosing trusted brands such as Rheem heat pump hot water and Rheem solar hot water for reliability, while many see Sanden heat pump units as among the best heat pump hot water system options on the market. Rinnai solar hot water and Chromagen solar hot water are also popular where roof space and good northern exposure make solar hot water installation an easy win. For many households, the best hot water system Australia can offer is simply the one that balances upfront hot water system price or cost with very low running bills and long warranties.

In Merrijig and the wider 3723 area, there have already been 154 efficient hot water installations, combining heat pump hot water installation and solar hot water installation. Installations spiked around 2009, with 38 systems going in that year, and there has been a steady trickle every year since, including new systems in 2017, 2018, 2019 and 2024. This long-term trend shows growing interest in electrification, lower running costs and a more energy efficient hot water system that suits local conditions.

Hot Water Rebates, Tariffs & Savings

The interest in hot water VIC upgrades is being driven not just by energy prices, but by generous incentives. For Merrijig homeowners, Australian Government Small-scale Technology Certificates (STCs) can reduce the solar hot water price or cost, as well as the heat pump hot water price or cost, at the point of sale. On top of that, state-based hot water rebate VIC programs often include a solar hot water rebate, heat pump hot water rebate and even an electric hot water system rebate when replacing old, inefficient units. Combined, these discounts can effectively cut the system cost by a substantial percentage and bring payback periods down to just a few years, especially if you already have solar and use timers or solar diversion to run your system when the sun is shining.

For many households weighing up solar hot water vs electric hot water or electric hot water vs gas hot water, the numbers now strongly favour efficient electric options. The most efficient hot water system for your home might be a Sanden heat pump paired with solar, a Rheem solar hot water tank replacement, or a compact Rinnai solar hot water system. The right choice depends on your roof, budget and how much hot water repair or solar hot water repair your current unit needs.
