For a typical family, hot water can be 20–30% of household energy use, so switching to the most efficient hot water system can deliver meaningful savings year after year. Annual hot water energy savings for Blakehurst homeowners who upgrade from an old electric or gas unit can easily reach hundreds of dollars, especially when paired with existing rooftop solar.
In 2221, there is a mix of larger family homes and townhouses, with strong demand from families and older couples alike. That means a wide range of system sizes from compact 160–200L units through to 300L+ setups with solar hot water tank replacement where needed. Brands like Rheem heat pump hot water, Rinnai solar hot water, Sanden heat pump and Chromagen solar hot water are common choices locally, offering options from premium ultra efficient systems through to more budget friendly units that still qualify as an energy efficient hot water system.
Average annual bill savings in Blakehurst for common upgrade paths typically fall in these ranges:
• Old electric to heat pump hot water installation: $450–$900 per year • Gas to heat pump vs solar hot water: $300–$800 per year depending on tariff and usage • Gas to solar hot water installation: $300–$700 per year • Old electric to modern electric hot water installation with solar: $250–$500 per year
Local interest in efficient hot water is clear. There have already been 192 efficient hot water installations (heat pump and solar) recorded in the Blakehurst postcode. Installations ramped up sharply around 2005 and peaked in 2009, with 56 systems installed in that year alone. While yearly numbers have been smaller since, recent activity in 2021 and 2024 shows ongoing growth as more households look at electrification, lower running costs and moving away from gas hot water.
When it comes to hot water repair and hot water installation, Blakehurst homeowners are increasingly weighing up electric hot water vs gas hot water, and heat pump vs solar hot water. A key factor is hot water system price and long term savings. A quality heat pump hot water system price may look higher upfront than a basic electric unit, but once you factor in the heat pump hot water rebate and lower running costs, the payback period can be quite short. The same applies to a solar hot water price when you include solar hot water rebate support and Small-scale Technology Certificates (STCs).
For many homes, the best hot water system Australia wide for long term savings is either a high quality heat pump such as a Sanden heat pump or Rheem heat pump hot water unit, or a well designed solar hot water system using brands like Rinnai solar hot water or Chromagen solar hot water. Others prefer a simpler electric hot water system rebate eligible upgrade, especially if they already have a decent solar PV array and can use timers or solar diversion to maximise self consumption. In all cases, an electric hot water installation can help households move towards an all electric home and away from volatile gas prices.
Hot Water Rebates, Tariffs & Savings
In Blakehurst NSW, there is strong interest in replacing older gas or electric units with efficient options. Between Federal STCs and state-based hot water rebate NSW programs, eligible homeowners can access a solar hot water rebate, a heat pump hot water rebate or an electric hot water system rebate depending on the technology they choose. These incentives can effectively reduce the upfront hot water system price or heat pump hot water price by a substantial percentage, making premium systems far more accessible.
For many Blakehurst households, typical savings from an efficient hot water upgrade are in the order of a few hundred dollars per year, and even more if they already have solar PV. When rebates and solar are combined, payback periods for a solar hot water vs electric hot water or heat pump upgrade can be cut to just a few years. Smart use of timers, off peak tariffs and solar diversion can further improve savings and make your hot water NSW bills much more manageable.
