The Maitland Belmore Bridge weather station records an average annual solar exposure of about 16.7 MJ/m² per day – roughly 4.6 kWh of usable solar energy per square metre, per day. That strong sunlight supports both a solar hot water system and a heat pump hot water system, especially when paired with rooftop solar. Upgrading from an old gas or resistive electric hot water system to a heat pump or solar hot water heating system can deliver sizeable annual hot water energy savings for Mount Dee homeowners.
Around 9,700 local homes are owned outright or with a mortgage, so plenty of residents can choose a hot water upgrade that suits their long term plans. Many are weighing up heat pump vs solar hot water, or even a modern electric hot water system that runs mainly on solar. Brands like Rheem heat pump hot water, Sanden heat pump units, Rinnai solar hot water and Chromagen solar hot water are all common options when people ask for the most efficient hot water system or the best heat pump hot water system for their family.
In 2320, efficient hot water is becoming a bigger slice of the energy picture. For a typical three or four bedroom home, hot water can account for up to a third of electricity use, so shifting to an energy efficient hot water system has a real impact. Locals are looking at solar hot water vs electric hot water, and even electric hot water vs gas hot water, to work out what delivers the best mix of comfort, reliability and savings.
Typical annual bill savings in Mount Dee look like:
• Old electric to heat pump hot water system: about $350–$700 per year • Gas to heat pump hot water system: about $250–$500 per year • Gas to roof mounted or split solar hot water system: about $200–$450 per year • Old electric to modern electric hot water system with solar PV: about $200–$400 per year

Hot Water Rebates, Tariffs & Savings
Across Mount Dee, more people are now 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 systems, effectively acting as an upfront discount on the solar hot water price / cost or heat pump hot water price / cost. On top of this, NSW hot water rebate programs for heat pumps and efficient electric units can further reduce the hot water system price / cost for homeowners.
Depending on the model and eligibility, combined solar hot water rebate, heat pump hot water rebate and electric hot water system rebate support can trim the installed cost by a substantial percentage, often shortening payback periods to just a few years. When you add timers, smart controls or solar diversion that sends excess rooftop solar into your electric hot water system instead of the grid, many Mount Dee households are saving hundreds of dollars a year. For some, that turns an already energy efficient hot water system into the best hot water system Australia has to offer for their situation.
