Hot Water Systems in Mordialloc

Hot water systems in Mordialloc

Across Mordialloc and the 3195 area, more households are swapping old gas and electric units for an energy efficient hot water system. With an average household size of around 2.6 people and more than 13,700 occupied dwellings, hot water is a big part of local energy use. Many homes are owned with a mortgage or outright, so investing in a modern hot water system that cuts running costs is a logical next step, especially as power prices keep rising.

Mordialloc’s coastal climate and strong sunlight make it ideal for efficient hot water. The Moorabbin Airport weather station records mean daily solar exposure of about 15.2 MJ/m², or roughly 4.2 kWh/m² per day over the year. That level of sunshine supports reliable performance from a solar hot water system, solar hot water heating system or a heat pump hot water system using ambient air. When you upgrade from an older gas or electric hot water system, annual hot water energy savings can be substantial, often hundreds of dollars a year for a typical family in Mordialloc.

With a mix of separate houses and townhouses, plus more than 1,700 flats and apartments, there’s no one-size-fits-all solution. Families and downsizers alike are looking at the best hot water system Australia can offer for their situation, whether that is a compact electric hot water system, a high-performance heat pump hot water system or a roof-mounted solar hot water installation. Brands like Rheem heat pump hot water and Rheem solar hot water are popular for reliability, while Sanden heat pump units are well regarded as some of the best heat pump hot water system options for efficiency. Rinnai solar hot water and Chromagen solar hot water are also common choices for solar hot water tank replacement and new builds.

In 3195, efficient hot water installations have steadily grown, with 940 heat pump and solar hot water systems installed to date. Installations picked up from the mid‑2000s, peaking around 2009, and there has been renewed interest again in recent years, with dozens of systems going in each year from 2017 onwards. This trend shows how households in Mordialloc are moving towards electrification, lower running costs and a more energy efficient hot water system as their old units reach the end of their life.

For many homes, hot water can account for 20–30% of electricity use, so the right hot water upgrade can make a real dent in bills. Typical annual bill savings in Mordialloc might look like:

• Old electric to heat pump hot water system: $450–$900 per year • Gas to heat pump hot water system: $350–$700 per year • Gas to solar hot water system: $300–$650 per year • Old electric to modern electric hot water installation with solar PV: $250–$600 per year

When comparing heat pump vs solar hot water, local roof space, shading, household size and hot water demand all matter. A heat pump hot water installation usually suits smaller blocks or shaded roofs, while a solar hot water installation can be ideal for sunny roofs with good north or north‑west exposure. Many Mordialloc homes already have rooftop solar, making solar hot water vs electric hot water a timely conversation, especially if you want to maximise self‑consumption of your solar generation.

Hot water repair and replacement is often the moment to rethink your setup. Instead of a like‑for‑like gas storage tank, more residents are choosing an energy efficient hot water system such as a Sanden heat pump or a quality Rheem or Rinnai unit. The heat pump hot water price or cost, and solar hot water price or cost, can look higher upfront than a basic electric hot water installation, but lower running costs and hot water rebate VIC incentives help balance it out. Over the system’s life, the total hot water system price or cost is often lower for efficient options.

Hot Water Rebates, Tariffs & Savings

Around Mordialloc, interest is growing in replacing old gas or electric hot water with efficient options like a heat pump hot water system, a newer electric hot water system or a solar hot water system. Federal incentives such as Small-scale Technology Certificates (STCs) apply to eligible heat pump and solar hot water installations, effectively acting as an upfront discount. On top of that, state programs can offer a heat pump hot water rebate, solar hot water rebate or electric hot water system rebate for qualifying homes, further reducing the heat pump hot water price or cost and solar hot water price or cost.

For many Mordialloc households, these hot water rebate VIC programs can cut the system cost by a substantial percentage and shorten the payback period to just a few years, especially if you already have solar PV. Using timers or smart controls to run your electric hot water system when solar is producing can boost savings even more. Compared with electric hot water vs gas hot water, an efficient heat pump or solar hot water system can be the most efficient hot water system choice, slashing bills and emissions at the same time.
