Hot water systems in Mulgrave
Across Mulgrave, more homeowners and local businesses are rethinking their hot water system and moving to energy efficient options like a heat pump hot water system, solar hot water system and modern electric hot water system. With power prices rising and many households aiming for an all‑electric home, upgrading away from old gas or ageing electric units is becoming the logical next step.
Mulgrave’s climate is ideal for efficient hot water. The Windsor Bowling Club weather station records around 16.2 MJ/m² of solar exposure a day on average – roughly 4.5 kWh/m² – which is strong support for a solar hot water heating system or a high quality heat pump hot water system. In postcode 2756 there are more than 11,700 occupied private dwellings, most of them separate houses with an average household size of 2.9 people, so hot water demand is solid. With over 8,500 homes either owned outright or with a mortgage, plenty of families are in a good position to invest in long‑term energy savings from an energy efficient hot water system.
For a typical Mulgrave family of three to four people, hot water can be one of the biggest single energy loads in the home. That is why the choice between heat pump vs solar hot water, or solar hot water vs electric hot water, really matters. Modern systems from brands like Rheem, Rinnai, Sanden and Thermann are designed to work well with rooftop solar, off‑peak tariffs and smart controls so you get reliable hot water with far lower running costs.
In the 2756 area there have already been 886 efficient hot water installations, combining heat pump hot water installation and solar hot water installation. Install numbers jumped sharply around 2009 and 2010, then settled into steady yearly demand, showing strong local interest in cutting bills and emissions. Recent years still see new systems going in as more households electrify, replace old gas hot water and look for the most efficient hot water system they can afford.
Typical savings will depend on your current setup and the hot water system price or cost, but many Mulgrave homes see meaningful reductions in bills. As a guide, average annual bill savings can look like this:
• Old electric to heat pump: $400–$800 per year • Gas storage to heat pump: $300–$600 per year • Gas storage to solar hot water: $250–$550 per year • Old electric to modern electric with good solar: $250–$500 per year
When you are comparing options, it helps to look at total ownership cost, not just the upfront heat pump hot water price or cost, solar hot water price or cost, or electric hot water installation fee. A premium sanden heat pump or rheem heat pump hot water unit may cost more to buy but can pay for itself sooner through lower running costs. Likewise, a rheem solar hot water, rinnai solar hot water or chromagen solar hot water system paired with PV can dramatically cut the electricity used for water heating. For homes staying with an electric hot water system, choosing an efficient model and using timers or solar diversion can still make a big difference.
Hot Water Rebates, Tariffs & Savings
There is growing interest in hot water NSW upgrades as households look to move away from gas and older resistive tanks.
