With an average household size of around 2.8 people and more than 6,300 occupied dwellings, reliable hot water is essential – but so is keeping running costs under control. Rising energy prices mean upgrading to a heat pump hot water system, solar hot water system or efficient electric hot water system is becoming the logical next step.
Grenville’s solar exposure averages about 15.1 MJ/m² a day over the year, which equates to roughly 4.2 kWh/m² of sunshine daily – ideal conditions for a solar hot water heating system or a high performance heat pump.

In practical terms, the most efficient hot water system for your home will depend on your roof space, power supply and hot water demand. A solar hot water system with roof panels and a well-insulated solar hot water tank replacement suits many of Grenville’s separate houses, especially when paired with rooftop solar. A quality heat pump hot water system, such as a Sanden heat pump or Rheem heat pump hot water unit, can be a great choice where roof space is limited or shading is an issue. Brands like Rheem solar hot water, Rinnai solar hot water and Chromagen solar hot water are common options when people research the best hot water system Australia wide and then narrow it down to what works in hot water VIC conditions.
For some homes, a modern, well-insulated electric hot water system still makes sense, especially when linked to rooftop PV or off-peak tariffs. Electric hot water vs gas hot water is increasingly tilting towards electric in Grenville as residents look to decarbonise and future-proof their homes. Many homeowners compare heat pump vs solar hot water, or solar hot water vs electric hot water, to find the right balance of upfront hot water system price / cost, running expenses and maintenance. Typical heat pump hot water price / cost and solar hot water price / cost can look higher at first, but lower bills and rebates often deliver a solid payback.
Around Grenville, hot water energy use can be a big slice of the household bill, so upgrading pays off. As a guide, average annual bill savings can look like:
• Old electric to heat pump hot water installation: $400–$800 per year • Gas storage to heat pump hot water installation: $300–$600 per year • Gas storage to solar hot water installation: $250–$550 per year • Old electric to modern electric hot water installation with solar: $200–$450 per year
Brands such as Sanden, Rheem and Rinnai are popular choices when locals are hunting for the best heat pump hot water system or a dependable solar hot water installation. Many households also look for prompt hot water repair and solar hot water repair services to keep existing systems running efficiently rather than replacing too early, helping manage overall hot water system cost.
Efficient hot water has been steadily taking off in Grenville. There have already been 1,457 efficient hot water systems installed in the 3352 postcode, covering both heat pump and solar hot water installation projects.

Even in recent years, dozens of new systems go in annually, reflecting growing interest in electrification, lower running costs and energy efficient hot water system options.
Hot Water Rebates, Tariffs & Savings
