Hot water systems in Goulburn
Across Goulburn, more households are swapping old gas and ageing electric units for modern, energy efficient hot water. With an average household size of around 2.4 people and more than 11,900 occupied dwellings, reliable hot water is a big part of everyday life here. Rising energy costs mean upgrading your hot water system is often the next logical step after solar panels, especially when you factor in the strong local sunshine. Goulburn’s average annual solar exposure is about 16.8 MJ/m² a day (roughly 4.7 kWh/m²), which is ideal for a solar hot water system, a heat pump hot water system, or a modern electric hot water system powered by rooftop solar. For many families and homeowners paying around $1,700 a month on mortgages, the annual hot water energy savings from switching away from old gas or resistive electric units can make a real difference to the budget.
In 2580, most people live in separate houses with three or four bedrooms, so hot water demand is steady year‑round. A typical family might use a third of their household energy just on hot water. That is why more locals are looking at the most efficient hot water system they can afford, weighing up heat pump vs solar hot water, and even going all‑electric. Brands like Rheem heat pump hot water, Sanden heat pump units and Rinnai solar hot water are common choices for efficient upgrades, while chromagen solar hot water also appears on many roofs as a proven solar hot water heating system. When you compare solar hot water vs electric hot water, or electric hot water vs gas hot water, it is clear that running costs and emissions are usually far lower with a quality energy efficient hot water system.
For Goulburn, realistic bill savings from a hot water installation or replacement often look like this:
• Old electric to heat pump hot water installation: save roughly $350–$700 per year • Gas storage to heat pump hot water system: save around $250–$600 per year • Gas to solar hot water installation (with electric boost): save about $300–$650 per year • Old electric to efficient electric hot water installation with solar: save around $200–$500 per year
Over time, those savings help offset the hot water system price or cost, whether you choose a Sanden heat pump, Rheem solar hot water, Rinnai or Chromagen. Many homeowners now ask which is the best hot water system Australia‑wide, or the best heat pump hot water system for their family size, rather than just replacing like‑for‑like.
Efficient hot water is not new to Goulburn. There have already been 318 efficient hot water systems installed in the 2580 postcode, including both heat pumps and solar hot water installation projects.
