Hot Water Systems in Mornington

Hot water systems in Mornington

Across Mornington and the wider 7018 area, more households are swapping tired old gas and electric units for a modern hot water system that is cheaper to run and easier on the environment. With an average household size of around 2.4 people and more than 9,400 dwellings in the postcode, reliable hot water is a big slice of local energy use. As power prices rise and many families juggle median mortgages of about $1,600 a month, upgrading to an energy efficient hot water system is becoming the logical next step after installing rooftop solar.

Mornington’s climate is well suited to efficient hot water. The local solar exposure at Mount Rumney averages about 13.9 MJ/m² per day over the year, which is roughly 3.9 kWh/m² per day. That steady sunlight supports both a solar hot water system and a heat pump hot water system, especially when paired with PV panels. For many owners who have already electrified heating and cooking, shifting from gas hot water to a heat pump hot water system or a high-efficiency electric hot water system is one of the easiest ways to lock in annual hot water energy savings.

In a suburb where more than 3,600 homes are owned outright and over 3,100 are mortgaged, long-term running costs matter. Families and retirees alike are comparing heat pump vs solar hot water, looking at the hot water system price and deciding what fits their budget and roof space. Brands like Rheem, Rinnai, Sanden and Thermann are common choices locally, with options ranging from rheem solar hot water and chromagen solar hot water style systems through to sanden heat pump and rheem heat pump hot water units that are among the best heat pump hot water system choices on the market.

Across the 7018 postcode there have been 286 efficient hot water installations recorded, combining heat pump hot water installation and solar hot water installation. Install numbers climbed strongly from 2008, peaking around 2010–2011, when many households first tapped into rebates for a solar hot water heating system. While yearly totals have eased back since, recent installs in 2024 and 2025 show steady interest as people replace ageing cylinders and consider the most efficient hot water system for their home. This trend towards electrification reflects a broader local push to cut running costs and future-proof homes in Mornington.

When you look at hot water energy use versus overall household energy, the savings can be significant. Typical annual bill reductions for Mornington homes can look like:

• Old electric to quality heat pump: save roughly $350–$700 per year. • Gas storage to heat pump: save around $250–$550 per year. • Gas to roof-mounted solar hot water: save about $250–$600 per year. • Old electric to modern electric hot water with solar diversion: save about $200–$450 per year.

Actual figures vary with tariffs, usage and whether you run timers or use solar diversion, but it is clear that an energy efficient hot water system can make a real dent in bills.

Rebates are another big driver. Federal incentives through Small-scale Technology Certificates (STCs) help cut the upfront solar hot water price / cost or heat pump hot water price / cost, and there are state-based hot water rebate tas programs that can further reduce the hot water system price / cost for eligible Mornington households. Depending on the setup, discounts can effectively knock a substantial percentage off a solar hot water price / cost or a heat pump hot water price / cost, shortening payback times to just a few years, especially if you already have solar PV. There are also electric hot water system rebate options in some schemes that reward moving away from gas.

Many locals are weighing up electric hot water vs gas hot water, or solar hot water vs electric hot water, when their old unit fails. Some opt for a straightforward electric hot water installation as a stopgap, while others go straight to a hot water upgrade with a heat pump or solar hot water heating system. For homes with older roof collectors, a solar hot water tank replacement combined with solar hot water repair can breathe new life into an existing system. Regular hot water repair and servicing also helps keep any hot water system running efficiently, whether it is a rinnai solar hot water setup, rheem solar hot water system or a newer sanden heat pump.
