Hot water systems in Knockwood
Across Knockwood and the wider 3723 area, more households are shifting from old gas and electric units to an energy efficient hot water system that keeps bills down and showers hot all year round. With an average household size of around 2.2 people and many homes owned outright or with a mortgage, a modern hot water system is a simple upgrade that can make a real dent in running costs, especially with energy prices rising.
Knockwood enjoys solid solar exposure, with average daily sunshine equivalent to roughly 4.2 kWh per square metre, which suits both a solar hot water system and a heat pump hot water system. That means a well designed solar hot water heating system or a quality heat pump, such as a Sanden heat pump or Rheem heat pump hot water unit, can work efficiently even through the cooler Victorian months. For many families and retirees on median household incomes around $1,293 per week, it is an easy way to lock in long term savings without sacrificing comfort.
Locally, separate houses dominate the 1,218 occupied dwellings, and hot water demand is steady rather than extreme, which suits a wide range of options. A modern electric hot water system paired with rooftop solar can be surprisingly efficient, and for some homes, the best hot water system Australia offers might be a smart electric unit on a timer. Others will find the most efficient hot water system is a high performance heat pump hot water system or a roof mounted solar hot water installation. Brands like Rheem solar hot water, Rinnai solar hot water and Chromagen solar hot water are common choices, while heat pump specialists such as Sanden are popular for those chasing the best heat pump hot water system.
When you look at hot water system price and ongoing costs, the numbers are compelling. Roughly speaking, households in Knockwood can expect average annual bill savings like:
• Old electric to heat pump: $400–$800 per year • Gas to heat pump: $300–$700 per year • Gas to solar hot water: $250–$600 per year • Old electric to modern electric with solar: $200–$500 per year
These savings stack on top of the Annual Hot Water Energy Savings that come from moving to an energy efficient hot water system, especially when hot water energy use can be one of the largest single loads in a smaller home.
In the 3723 postcode there have already been 154 efficient hot water installations, combining both heat pump hot water installation and solar hot water installation. Installations really took off around 2008–2012, with a peak of 38 systems in 2009 and solid numbers through 2010, 2011 and 2012. More recent years show a steadier trickle of upgrades, reflecting ongoing interest in electrification, lower running costs and getting away from ageing gas hot water. Each new solar hot water tank replacement or hot water repair is an opportunity for Knockwood households to step into cleaner, cheaper technology.
Even if you are simply planning a like for like electric hot water installation, it pays to understand rebates and tariffs. Across hot water VIC programs, there are Australian Government Small-scale Technology Certificates (STCs) that apply to eligible heat pump and solar hot water systems, effectively acting as an upfront discount. On top of that, state based schemes can offer a heat pump hot water rebate, solar hot water rebate or even an electric hot water system rebate in some circumstances. For many Knockwood homes, these incentives can cut the heat pump hot water price or solar hot water price by a substantial percentage, bringing the overall hot water system cost closer to a basic replacement.
When you factor in typical savings of hundreds of dollars per year, the payback period on a quality system can shrink to just a few years, especially if you also have solar PV and use timers or smart controls to run your electric hot water vs gas hot water at the cheapest times. For some properties, solar hot water vs electric hot water will come down to roof space and household pattern of use, but in both cases the aim is the same: a reliable, energy efficient hot water system that keeps bills low and emissions down.
If your current unit is old, noisy or needing frequent hot water repair, it is a good time to compare heat pump vs solar hot water, look at options like Rheem solar hot water, Rinnai solar hot water or a Sanden heat pump, and decide what will future proof your home.
